The plane that contains points C and T can also be named plane...

A) CUB
B) BED
C) ACE
D) ABE

Answer:

Step-by-step explanation:

The values at two points that differ by 1 year differ by $125, so the slope is $125 per year.

The graph shows the total cost of membership, which includes the initiation fee (y-intercept) and yearly membership dues (increase per year). The slope represents the increase per year: the yearly membership dues.

The slope of a line is determined by the change in the y-axis divided by the change in the x-axis. In this case without specific graphical data, it is conjectured that the slope may represent the yearly membership cost increase or decrease over time. A positive slope shows an increase, while a negative slope shows a decrease.

The question seems to be asking about the slope of a line related to the cost of a membership at a nature preserve. However, the provided reference information does not connect directly to this question, but outlines concepts of slope in economics and business scenarios rather than the nature preserve context. In general, the slope of a line is calculated by the change in the y-axis divided by the change in the x-axis. In this context, without a graph, one can conjecture that the slope may represent the yearly membership cost increase or decrease over time. A positive slope indicates an increase, whereas a negative slope indicates a decrease.

Answer:

  17.2 m

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you the relationship between the adjacent side of a right triangle and the opposite side is given by ...

  Tan = Opposite/Adjacent

Filling in the given information, we have ...

  tan(25°) = (8 m)/distance

  distance = (8 m)/tan(25°) ≈ 17.156 m

The man is about 17.2 meters from the tower.

Final answer:

The distance of the man from the tower can be found by dividing the height of the tower (8m) by the tangent of the 25-degree angle, using trigonometry.

Explanation:

The distance of the man from the tower is determined using trigonometry, where we have a right-angled triangle with the tower's height as the opposite side and the distance of the man from the tower as the adjacent side to the 25-degree angle.

To find the adjacent side (the distance from the man to the tower), we can use the trigonometric function tangent, which relates the opposite side to the adjacent side in a right-angled triangle.

The formula is:

tangent(25 degrees) = opposite / adjacent

Plugging in the value of the tower's height:

tangent(25 degrees) = 8m / distance

Solving for the distance:

distance = 8m / tangent(25 degrees)

Answer:

1.5 < x < 4

Step-by-step explanation:

Let x be the pH of lemon juice

As it is said that the pH is less than it will be denoted by

x<4

Similarly it is also given that lemon juice's pH is greater than 1.5

x>1.5

So,

both inequalities will be combined.

1.5 < x < 4

It is read as x is greater than 1.5 and less than 4 ..

So option 2 is correct ..

Final answer:

The correct compound inequality to represent the normal pH range of lemon juice is 1.5 < x < 4, where x is the pH value. It indicates that the pH of lemon juice is greater than 1.5 but less than 4.

Explanation:

The pH scale measures how acidic or basic a substance is. To model the normal range of pH values for lemon juice, which is said to have a pH of less than 4 and greater than 1.5, we must use a compound inequality. A compound inequality that accurately represents this scenario is 1.5 < x < 4, where x stands for the pH value of lemon juice. It is important to use the less than symbol (<) and not the less than or equal to symbol (≤) because a pH of exactly 1.5 or 4 is not included in the "normal" range as stated.

Answer: Option 1) 2.33

Step-by-step explanation:

For the 98% confidence interval we have that the area between 0 and the z score is equal to:

98% corresponds to 0.98

then the area between 0 and z is half of that:

a = 0.98/2 = 0.490

Now you can search in a table, and you will find that the z-score for this is z = 2.326

So the correct answer is 1) 2.33

where the result is rounded up.

The value of z we should  use when making a 98% confidence interval for p is mathematically given as

x= 2.33

Answer:

If there's no limits on the shape of the triangle, the length of the third side shall be between (excluding the endpoints)

Step-by-step explanation:

Let the length of the third side be [tex]x[/tex] kilometers. The length of each side shall be positive. In other words, [tex]x > 0[/tex].

Consider the triangle inequality theorem. The sum of any two ends shall be greater than the third end. For this triangle, the lengths of the three sides are:

By the triangle inequality theorem,

[tex]\left\{\begin{aligned}& 20 + 35 > x\\ & 20 + x > 35\\ & 35 + x > 25\end{aligned}\right.[/tex].

Rewrite and simplify each inequality:

[tex]\left\{\begin{aligned}& x < 55\\ & x > 15\\ & x > -15\end{aligned}\right.[/tex]

[tex]x[/tex] shall satisfy all three inequalities. As a result, the range of [tex]x[/tex] shall be the intersection of the solution sets of all three inequalities.

Refer to the sketch attached. On the sketch, the intersection is the region where the three colored lines are above each other. That's represents the interval

Answer:

Iris can make 2 hats in an hour.

Step-by-step explanation:

3 hats in one and a half hours is 1 hat per half hour. 2 hats would take two half hours, which is one whole hour.

She can make 2 hats.

Since she can make 3 hats in 1.5 hours, divide 1.5 by 3 to find the unit amount of hats she can make.

1.5/3=.5

.5 of an hour is 30 mins.

Now, multiply 30 mins by 2 to find the amount of time it would take to make 2 hats.

30*2=60 or 1 hour.

She can make 2 hats in an hour.

[tex]H=1\frac{1}{2}\ m=\frac{1*2+1}{2}=\frac{3}{2}\ m[/tex]

substitute

[tex]V=(19)(\frac{27}{2})(\frac{3}{2})[/tex]

[tex]V=\frac{1,539}{4}=384.75\ m^{3}[/tex]

Answer:

We'll be making 35 liters of 19% glucose.

How much of a 15% solution and a 35% solution do we mix in order to get 35 liters of a 19% glucose solution?

X = liters of 15% and Y = liters of 35%

(.15 X + .35 Y) / 35 = .19

The number of Y liters will equal (35 -X) so the equation becomes

(.15 X + .35 *(35-X) ) / 35 = .19

(.15X + 12.25 -.35X) / 35 = .19

(-.20 X / 35) + (12.25 / 35) = .19

(-.20 X / 35) + .35 = .19

(-.20 X / 35) = -.16

-.20X = -5.6

X = 28 liters of 15% and

Y = 7 liters of 35% glucose

Answer:

-x⁴ + 3x² is the standard form, and this is a quartic binomial.

Step-by-step explanation:

We look to see if there are any like terms first. x² and 2x² are like terms; they combine to make 3x². So this polynomial really only has two terms when simplified.

The standard form of a polynomial has all of its terms in decreasing order of degree.

  -x⁴ ⇒ degree 4

  3x² ⇒ degree 2

Therefore, standard form is

  -x⁴ + 3x²

The degree of this polynomial is the degree of the highest degree term, which is 4. A degree 4 polynomial is called a quartic polynomial.There are two terms, so we can further classify this as a binomial.

Therefore, the answer is quartic binomial

To round the sum of a sequence properly, consider the precision of the terms given. For example, an answer of 921.996 from a calculator should be rounded to 922.00, aligning with the hundredth place of the term 13.77 as the most precise figure. Apply appropriate rounding rules such as rounding up if the next digit is greater than 5.

When calculating the sum of a sequence and needing to round the answer to a specific decimal place, we must pay close attention to the significant figures and rounding rules.

For instance, if a calculator gives an answer of 921.996, we should round to the nearest hundredth.

This is because the last significant figure in the given sequence's general term (for example, 13.77) is in the hundredth place.

Following the rule of rounding, if the first digit to be dropped is greater than 5, we round up.

Therefore, the answer would be rounded to 922.00.

Let's consider other examples:

For the calculation resulting in 119.902, since we're limiting it to the tenths place, we round down to 119.9.

For 201.867, rounding to the hundredth place gives us 201.87.

When rounding 2,085.5688 to five significant figures, we get 2,085.6.

For a quick intuitive check, recall that one eighth of 1,000 is 125, a simple multiplication by a reciprocal number without doing long division.

In summary, always align your rounding method to the precision indicated by the sequence terms or the specific requirements of the question.

Answer:

[tex]x = 16.6\ cm[/tex]

Step-by-step explanation:

To answer this question use the secant line theorem.

If two secant segments are drawn towards a circle from an outer point, then the product of the length of the secant segment y and the length of its outer secant segment is equal to the product of the length of the other secant segment and its external secant segment.

This is:

[tex](12+6)*6 = (5+x)*5[/tex]

Now we solve the equation for the variable x

[tex]18*6 = 5*5+x*5[/tex]

[tex]108 = 25+5x[/tex]

[tex]5x = 108-25[/tex]

[tex]5x = 83[/tex]

[tex]x = \frac{83}{5}[/tex]

Answer:

the vertex is:

(2, -1)

Step-by-step explanation:

First solve the equation for the variable y

[tex]x^2-16y-4x-12=0[/tex]

Add 16y on both sides of the equation

[tex]16y=x^2-16y+16y-4x-12[/tex]

[tex]16y=x^2-4x-12[/tex]

Notice that now the equation has the general form of a parabola

[tex]ax^2 +bx +c[/tex]

In this case

[tex]a=1\\b=-4\\c=-12[/tex]

Add [tex](\frac{b}{2}) ^ 2[/tex] and subtract [tex](\frac{b}{2}) ^ 2[/tex] on the right side of the equation

[tex](\frac{b}{2}) ^ 2=(\frac{-4}{2}) ^ 2[/tex]

[tex](\frac{b}{2}) ^ 2=(-2) ^ 2[/tex]

[tex](\frac{b}{2}) ^ 2=4[/tex]

[tex]16y=(x^2-4x+4)-4-12[/tex]

Factor the expression that is inside the parentheses

[tex]16y=(x-2)^2-16[/tex]

Divide both sides of the equality between 16

[tex]\frac{16}{16}y=\frac{1}{16}(x-2)^2-\frac{16}{16}[/tex]

[tex]y=\frac{1}{16}(x-2)^2-1[/tex]

For an equation of the form

[tex]y=a(x-h)^2 +k[/tex]

the vertex is: (h, k)

In this case

[tex]h=2\\k =-1[/tex]

the vertex is:

(2, -1)

The answer is:

The interval notation will be:  (-∞,-1.59) and (-4.41,∞+)

To solve the expression, we need to perform the following steps:

- Find the roots or zeroes of the expression:

Using the quadratic equation, we have:

[tex]\frac{-b+-\sqrt{b^{2}-4*a*c } }{2*a}[/tex]

We are given the quadratic expression:

[tex]x^{2} +6x+7[/tex]

Where,

[tex]a=1\\b=6\\c=7[/tex]

Then, substituting and calculating we have:

[tex]\frac{-6+-\sqrt{6^{2}-4*1*7 } }{2*1}=\frac{-6+-\sqrt{36-28 } }{2}\\\\\frac{-6+-\sqrt{36-28}}{2}=\frac{-6+-\sqrt{8}}{2}\\\\x_{1}=\frac{-6+\sqrt{8}}{2}=\frac{-6+2.82}{2}=-1.59\\\\x_{2}=\frac{-6-\sqrt{8}}{2}=\frac{-6-2.82}{2}=-4.41[/tex]

- Inequality interpretation:

Now that we already know the roots of the quadratic expression, and we can see that the parabola open upwards (positive quadratic coefficient), we can conclude that the function is less than 0 between the numbers -4.41. and -1.59

The interval notation will be:and  (-∞,-1.59) and (-4.41,∞+)

Answer: There are 30 gallons of anti freeze of  first brand and 120 gallons of anti freeze of second brand.

Step-by-step explanation:

Since we have given that

Percentage of anti freeze in first brand = 35%

Percentage of anti freeze in second brand = 85%

Percentage of anti freeze in mixture = 75%

Total number of gallons of mixture = 150 gallons

We will use " Mixture and Allegation":

 First brand         Second brand

      35%                      85%

                      75%

------------------------------------------------------------------

85%-75%         :            75%-35%

    10                :               40

     1                 :                 4

So, Number of gallons of anti freeze in first brand is given by

[tex]\dfrac{1}{5}\times 150\\\\=30\ gallons[/tex]

Number of gallons of anti freeze in second brand is given by

[tex]\dfrac{4}{5}\times 150\\\\=40\times 3\\\\=120\ gallons[/tex]

Hence, there are 30 gallons of anti freeze of  first brand and 120 gallons of anti freeze of second brand.

b.  quantitative, continuous

Step-by-step explanation:

Since here Dog = 0.07

Cat = 0.1

Snake = 0.12, and so on.

It is a numeric form So, it is quantitative data. And we can't count them(it include numbers between two natural number) so it is Continuous Variable.

The variable which is in numeric form is called Quantitative Variable. Example: Weight, Marks, etc.

And, the variable which we can't count is known as Qualitative Variable. Example: Smoking, Non- Smoking, etc.

Further Quantitative Variable can be divided into two parts:

The variable which we can count is known as the Discrete variable. It includes the natural numbers only. Example: Number of apples, Number of senior citizens in a particular area, etc.

The variable which we can't count is known as Continuous Variable. Example: Height, Weight, etc.

The company inventory consists of 51 bags of Colombian and 33 bags of Brazilian beans. Each bag holds 80 pounds of beans, so in total the company has 4080 pounds of Colombian and 2640 pounds of Brazilian beans.

The company wants to use up its entire inventory, a total of 6720 pounds of beans.

Let [tex]r[/tex] and [tex]m[/tex] denote the amount (in pounds) of the robust and mild blends, respectively, that the company should end up producing.

To use the entire inventory, we must have

[tex]r+m=6720[/tex]

Each pound of the robust blend uses 12 ounces (3/4 = 0.75 pound) of Colombian beans, and each pound of the mild blend uses 6 ounces (3/8 = 0.375 pound) of Colombian beans, so that

[tex]0.75r+0.375m=4080[/tex]

while each pound of the robust blend uses 4 ounces (1/4 = 0.25 pound) of Brazilian beans, and each pound of the mild blend uses 10 ounces (5/8 = 0.625 pound) of Brazilian beans, so that

[tex]0.25r+0.625m=2640[/tex]

Multiply both equations by 8 to get rid of the rational coefficients:

[tex]\begin{cases}6r+3m=32640\\2r+5m=21120\end{cases}[/tex]

Subtract 3(second equation) from (first equation) to eliminate [tex]r[/tex]:

[tex](6r+3m)-3(2r+5m)=32640-3\cdot21120[/tex]

[tex]-12m=-30720\implies\boxed{m=2560}[/tex]

Then

[tex]r+2560=6720\implies\boxed{r=4160}[/tex]

So the company needs to produce 4160 pounds of the robust blend and 2560 pounds of the mild blend.

Answer:

Right side towards positive x axis

Step-by-step explanation:

Let us see the basic rule to find the orientation of parabolas.

1.  If power if x is 2 and y is 1 , the parabola opens up or down.

2. If the power of y is 2 and that of x is 1 , the parabola opens right or left.

3. If the coefficient of [tex]x^{2}[/tex] in case 1 is negative it opens downward

4. If the coefficient of [tex]y^{2}[/tex]  in case 2 is negative , it opens left towards negative x axis.

Hence our equation is

[tex]x=y^2-9[/tex]

here is satisfies the case 2. hence it opens right or left . Also the coefficient of  

[tex]y^{2}[/tex] is positive so it opens up to the right side , that is towards positive x axis.

the correct answer is c.) right.

The student's question pertains to the orientation of a parabola described by the equation x = y² - 9. In order to determine the direction in which the parabola opens, we observe the equation. The parabola relates y² to x, indicating that for every value of y, we have a corresponding value of x. Since y² is the variable being squared and x is by itself, the parabola is a sideways parabola. Furthermore, because there is no negative sign in front of the y² term, the parabola opens to the right of the coordinate system. Therefore, the correct answer is c.) right.
