The answer is D- 20/12

Step-by-step explanation:

Answer: B

Step-by-step explanation: 6^2 = 36

36*4= 144

144-7= 137

Answer:

B. 137

Step-by-step explanation:

Assuming by 4x2 you meant 4[tex]x^{2}[/tex], you plug in the 6 into x.

After, you would square 6, giving you 36.

Then you multiply 36 by 4, getting 144

All that's left to do is subtract 7 from 144 and ending with 137.

Answer: The correct answer is option C; 90√2

Step-by-step explanation: The line segments are labelled as base 1, base 2 and base 3 respectively. This we shall call point 1, point 2 and point 3. These three points form a right angle. Also we have been told that Marcus is on point 3 and Jean is on point 2. They are both 90 feet apart. Also Joel is on point 1 and he is 90 feet away from Jean. The unmeasured distance therefore is from point 1 to point 3, which is the distance from Joel to Marcus (or Marcus to Joel).

The distance from point 1 to point 3 is the hypotenuse of the right angled triangle derived. Using the Pythagoras' theorem, the distance from  Joel to Marcus (or JM) is calculated as follows;

JM² = JC² + JL²

Where JM is the distance between Joel and Marcus (hypotenuse), JC is the distance from Jean to Marcus and JL is the distance from Jean to Joel.

JM² = 90² + 90²

JM² = 8100 + 8100

JM² = 16200

Add the square root sign to both sides of the equation

√JM = √16200

JM = √100*√81*√2

The right hand side of the equation can be further solved as

JM = 10*9*√2

JM = 90√2

Therefore the distance between Marcus and Joel is calculated as 90√2 feet

Answer: 9.2 meters

Step-by-step explanation:

Hi, since the situation forms a 2 right triangles (see attachment) we have to apply the Pythagorean Theorem:  

c^2 = a^2 + b^2  

Where c is the hypotenuse (x) of each triangle (in this case the distance between the opposite corners) and a and b are the other sides.  

Replacing with the values given:  

c^2 = 6^2 + 7^2  

c^2 = 36+49

c^2 = 85

c = √85

c = 9.2 meters

Feel free to ask for more if needed or if you did not understand something.  

Final answer:

To find the distance the gopher needs to run between the holes in a rectangle yard, use the Pythagorean Theorem with the given sides (7 meters by 6 meters) to calculate the diagonal distance of approximately 9.2 meters.

Explanation:

A gopher dug holes in opposite corners of a rectangle yard. If the yard is 7 meters by 6 meters, how far will the gopher have run to get from one of its holes to the other, rounded if necessary to the nearest tenth? Use the formula a square plus b square equals c square.

Identify the two sides of the rectangle as a and b, where a = 7 meters and b = 6 meters.

Apply the Pythagorean Theorem: a² + b² = c². Substitute the values: 7² + 6² = c².

Calculate the distance: 7² + 6² = c² ➔ 49 + 36 = c² ➔ 85 = c² ➔ c ≈ √85 ≈ 9.2 meters. So, the gopher would need to run approximately 9.2 meters to move between the holes.

Answer:

x=-1

Step-by-step explanation:

here is an example for my class, these really helped

A quadratic equation is any second-degree polynomial equation — that’s when the highest power of x, or whatever other variable is used, is 2. The solution or solutions of a quadratic equation,

Solve the equation,

with the quadratic formula:

Bring all terms to one side of the equation, leaviign

Plug the coefficients into the formula.

In this example, a equals 2, b is –5, and c is –12, so

You can also use the quadratic formula for factoring trinomials.

Here’s what you do.

Use the quadratic formula to get solutions for x. (You can also use your calculator to get the solutions.) Make sure the solutions are written as fractions rather than as decimals and that they’re reduced to lowest terms.

Take the two solutions and put them in factors. If a solution is positive, use subtraction. If a solution is negative, use addition.

If either solution is a fraction, take the denominator and bring it in front of the x.

And, voilà, the trinomial is factored:

(x – 4)(2x + 3)

Answer:

X= -1

Step-by-step explanation:

how u can see I apply the formula, and I have two answers X1= -1 and X2= -1

U only need to see the information that they give u, it was x^2+2x+1=0

and we know that

a= 1

b=2

c=1

then you replace in the formula and do the exercise:)

Why is this? Choice B is true because of the Pythagorean theorem. If vectors u and v are perpendicular, then we can form a rectangle. The diagonals of the rectangle are each of length ||u+v|| units long. From here you can form a right triangle with vector u+v as the hypotenuse. The expression shown in choice B is of the form c = sqrt(a^2+b^2), though with substitutions applied.

Choice D is true because of the triangle inequality theorem. This theorem says that the sum of any two sides of a triangle will always be larger than the third side. Otherwise, a triangle is not possible. I recommend cutting out strips of paper of various lengths and trying it out for yourself.

Choices A and C can be eliminated as they contradict B and D. Choice A contradicts choice D. Choice C contradicts choice B.

Answer:

x<2.5

Step-by-step explanation:

-4x +5>-5

-4x>-5-5

-4x>-10

x<10/4(on multiplying (-)ve sign both the sides inequality changes)

x < 2.5

The inequality -4x + 5 > -5 simplifies to x < 2.5 after isolating the variable and dividing by -4, which also reverses the inequality sign.

To solve the inequality -4x + 5 > -5, we first isolate the variable on one side:

Let's solve the inequality step-by-step:

Therefore, the solution to the inequality is x < 2.5.

You will find all of the surface area of all of the sides and add them together to find the surface area of the retangular prisim. So, what I would do is the front and back are both 54, so 108. The sides are 27, so 54. The top and bottom are 18, so 36. Add them together, and you will get 198. I hope this helps.

The value of n is 0 and the coordinate of D is at (0, -2)

Find the coordinate of the plane attached.

Given the following coordinates:

C = (0, -2)

D = (n, -2)

E = (n, 2)

Get the distance from point D to point E using the distance formula:

[tex]DE=\sqrt{(2+2)^2+(n-n)} \\DE=\sqrt{(4)^2} \\DE=4 units[/tex]

Get the distance from point D to point C using the distance formula:

[tex]DC=\sqrt{(2+2)^2+(n-n)} \\DC=\sqrt{(4)^2+n^2} \\DC=\sqrt{16+n^2}[/tex]

If the distance from point D to point E is equal to the distance from point D to point C, hence;

[tex]\sqrt{16+n^2}=4\\16+n^2=4^2\\n^2=16-16\\n=0[/tex]

Get the coordinate of point D(n, -2)

D = (0, -2)

Hence the value of n is 0 and the coordinate of D is at (0, -2)

The distance from point D to point E is 4 units. The value of n is indeterminable from the information given in the question.

In this question, we know the distance from point D to point E is equal to the distance from D to point C. Given this information, we can infer that coordinates of point E are (n, 2), while coordinates of point D are(n, -2). The distance formula on a cartesian plane is given by Distance = √[(x2-x1)² + (y2-y1)²].

Here, since D and E both have the same x-value (n), the distance between them depends only on the difference in their y-values. Therefore, the distance between D and E (and hence also D and C) is 4 units.

The value of n is irrelevant to the distance calculation, as it doesn't impact the distance between D and E or D and C. As such, it isn't possible to determine n's value given the information from the question.

Answer:

B) 5 x 4 x 3 x 2 x 1

Step-by-step explanation:

When you see a ! directly next to a number (such as 5!), it means that you are multiplying starting from that number, and stepping down each time:

5! = 5 * 4 * 3 * 2 * 1

For example, take factoral 10: 10!

10! = 10 * 9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1 = 3,628,800

In this case, you are multiplying 5!.

5! = 5 * 4 * 3 * 2 * 1 = (20) * (6) * 1 = 120

Primero tienes que hacer el 25% de ambas cantidades y luego sumarlo

The required, tax would be $25,750 if the Tanners file jointly.

The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.

Here,

Assuming that the tax rate of 25% applies to their combined taxable income, here's how to calculate their taxes if they filed jointly:

Calculate their combined taxable income:
$75,000 + $28,000 = $103,000

Calculate their tax liability based on their combined taxable income: $103,000 x 0.25 = $25,750

Therefore, the answer is C. $25,750, if the Tanners file jointly.

Answer:

c.  log 64.

Step-by-step explanation:

By the laws of logs:

3 log 4 = log 4^3

= log 64.

The correct value of the given logarithmic function is log 64. Option c is correct.

The opposite of an exponential function is a logarithmic function. A log function and an exponential function both use the same base. An exponent is a logarithm. [tex]f(x) = b^x[/tex] is how the exponential function is expressed. The formula for the logarithmic function is f(x) = log base b of x.

The expression 3 log 4 can be rewritten as:
