Answer:
[tex]t=46.4\ years[/tex]
Step-by-step explanation:
we know that
The compound interest formula is equal to
[tex]A=P(1+\frac{r}{n})^{nt}[/tex]
where
A is the Final Investment Value
P is the Principal amount of money to be invested
r is the rate of interest in decimal
t is Number of Time Periods
n is the number of times interest is compounded per year
in this problem we have
[tex]t=?\ years\\P=\$200\\A=\$500\\ r=1.98\%=1.98/100=0.0198\\n=4[/tex]
substitute in the formula above
[tex]500=200(1+\frac{0.0198}{4})^{4t}[/tex]
[tex]2.5=(1.00495)^{4t}[/tex]
Apply property of exponents
[tex]2.5=[(1.00495)^{4}]^t[/tex]
Apply log both sides
[tex]log(2.5)=log[(1.00495)^{4}]^t[/tex]
[tex]t=log(2.5)/log[(1.00495)^{4}][/tex]
[tex]t=46.4\ years[/tex]
Final answer:
To find when the investment of $200 at a 1.98% annual interest rate compounded quarterly will reach $500, we use the compound interest formula and solve for t, representing time in years.
Explanation:
The subject is Mathematics, specifically focusing on the concept of compound interest. To find out when the investment will reach $500, we can use the formula for compound interest:
[tex]A = P(1 + r/n)^(nt)[/tex]
Where:
A = the amount of money accumulated after n years, including interest.
P = the principal amount (the initial amount of money).
r = the annual interest rate (decimal).
n = the number of times that interest is compounded per year.
t = the time the money is invested for in years.
In the case of the student's question:
P = $200
n = 4 (since the interest is compounded quarterly)
A = $500
We rearrange the formula to solve for t:
t = (log(A/P)) / (n×log(1+r/n))
Substitute the given values:
t = (log(500/200)) / (4×log(1+0.0198/4))
Use a calculator to compute t, which will give us the number of years it takes for the investment to reach $500.
How can u solve 40x16 by breaking apart the numbers
Answer: 640
Step-by-step explanation:
You can break 16 up into 10 and 6: 40(10+6)
40(10)+40(6)
400+240
640
Final answer:
To solve 40x16, break apart the numbers into tens and use the distributive property to calculate the partial products, then sum up these products to get the final result of 640.
Explanation:
To solve 40x16 by breaking apart the numbers, you can use a strategy known as decomposing or partial products. Here's a step-by-step explanation:
Break apart the number 40 into 10s: 40 = 30 + 10.
Break apart the number 16 into 10s: 16 = 10 + 6.
Now use the distributive property to multiply each part:
(30 + 10) × (10 + 6)
Multiply each part individually: 30 x 10, 30 x 6, 10 x 10, and 10 x 6.
Calculate the partial products: 300, 180, 100, and 60.
Finally, add all the partial products: 300 + 180 + 100 + 60 = 640.
So, 40x16 equals 640 when you apply the breaking apart method.
factorise 9f²-12f plus 4
Answer:
(3f - 2)²
Step-by-step explanation:
Given
9f² - 12f + 4
Consider the factors of the product of the coefficient of the f² term and the constant term which sum to give the coefficient of the f- term.
product = 9 × 4 = 36 and sum = - 12
The factors are - 6 and - 6
Use these factors to split the f- term
9f² - 6t - 6t + 4 ( factor the first/second and third/fourth terms )
= 3f(3f - 2) - 2(3f - 2) ← factor out (3f - 2) from each term
= (3f - 2)(3f - 2)
= (3f - 2)²
Answer:
9f² - 12f + 4 = (3f - 2)²
Step-by-step explanation:
9f²-12f+4 =
= (3f)²-2×(3f)×(2)+2²
= (3f-2)²

n
a_{n}=9n-26a
n
=9n−26
a_{n}=-17-9(n-1)a
n
=−17−9(n−1)
Answer:
The nth term of the given arithmetic sequence is [tex]a_n=-17+(n-1)9[/tex]
Step-by-step explanation:
Given sequence is -17,-8,1,...
To find the nth term of the given sequence :
Let [tex]a_1=-17,a_2=-8,a_3=1,...[/tex]
To find the common difference d :
[tex]d=a_2-a_1[/tex]
[tex]=-8-(-17)[/tex]
[tex]=-8+17[/tex]
Therefore d=9
[tex]d=a_3-a_2[/tex]
[tex]=1-(-8)[/tex]
[tex]=1+8[/tex]
Therefore d=9
The common difference d is 9
Therefore the given sequence is an arithmetic sequence
The nth term of an arithmetic sequence is given below
[tex]a_n=a_1+(n-1)d[/tex]
Substitute [tex]a_1=-17[/tex] and d=9 in the above equation we get
[tex]a_n=-17+(n-1)9[/tex]
Therefore the nth term of the given arithmetic sequence is [tex]a_n=-17+(n-1)9[/tex]
The formula for the nth term of the sequence -17, -8, 1 is a_n = 9n - 26, where n is the position of the term in the sequence.
Explanation:The sequence provided is -17, -8, 1, which suggests that there is a common difference between terms since it is an arithmetic sequence. To find the nth term of an arithmetic sequence, we use the formula a_n = a_1 + (n - 1)d, where a_n is the nth term, a_1 is the first term, and d is the common difference. In this case, the common difference is 9 (since -8 - (-17) = 9).
So, using the formula for the nth term of an arithmetic sequence:
a_1 = -17 (the first term)d = 9 (the common difference)Our formula becomes a_n = -17 + (n - 1) × 9. Simplifying this:
a_n = -17 + 9n - 9
a_n = 9n - 26
Therefore, the formula for the nth term of the given sequence is a_n = 9n - 26.

if the measurement of the angle P is three less than twice the measure of angle Q and angle P and angle Q are supplementary angles. what is each angle measure
Answer:
Step-by-step explanation:
Let angle Q = x°
Angle P = (2x - 3)°
And angle P and Q are supplementary angle which implies there sum is 180°
x + 2x - 3 = 180
3x = 180 + 3
3x = 183
x = 183/3
x = 61°
Angle Q = 61°
Angle P = 2x - 3
Angle P = 2(61) - 3
Angle P = 122 - 3
Angle P = 119°

The population of Cincinnati is 301,305 people. If 28.7% of people in Cincinnati live poverty, how many people live in poverty
Answer:
86,475 people live in poverty.
Step-by-step explanation:
We are given that the Total Cincinnati population is [tex]X_{TOT}=301,305[/tex] people.
We want to find the [tex]28.7[/tex]% of the Total population that lives in poverty. To do so we can use:
[tex]X_{POV}=\frac{28.7}{100}X_{TOT}[/tex]
where [tex]X_{POV}[/tex] is the amount of people that live in poperty. Plugging in values and solving we have:
[tex]X_{POV}=\frac{28.7}{100}301,305 \\X_{POV}=0.287*301,305\\X_{POV}=86,474.535[/tex]
However since here we are referring to number of people (i.e. population) we can not accept any irrational values so we need to round up our value so that
[tex]X_{POV}=86,475[/tex] people live in poverty in Cincinnati.
To find how many people live in poverty in Cincinnati, multiply the city's total population by the given percentage (expressed as a decimal). In this case, it is 301,305 * 0.287, which equals 86,574. Thus, an estimated 86,574 people live in poverty in Cincinnati.
Explanation:To find out how many people live in poverty in Cincinnati, you need to calculate 28.7% of the city's total population. To calculate the percentage of a number, you can multiply that number by the percentage expressed as a decimal. The calculation will look like this:
Population x Percentage = Number of people in poverty
So, it will be:
301,305 x 0.287 = 86,574.135
Normally in population estimates, we don't count fractions of people, so we'll round this down to the nearest whole number. Therefore, the number of people living in poverty in Cincinnati is approximately 86,574.

f(x)= x2-5x+2. Find f(-4)
Answer:
f ( 4 ) = 18
Step-by-step explanation:
Explanation:
f ( x ) = 5 x − 2
Replace 4 instead of x to find f ( 4 )
f ( 4 ) = 5 ( 4 ) − 2 = 20 − 2 = 18
The value of f(-4) for the function f(x) = x^2 - 5x + 2 is 38.
Explanation:To find the value of f(-4) for the function f(x) = x^2 - 5x + 2, you substitute -4 for x in the function.
It looks like this:
f(-4) = (-4)^2 - 5(-4) + 2
First, you square -4, which is (-4)^2 = 16.
Then, you calculate -5 times -4, which is 20.
Finally, you add 2 to the result.
So, f(-4) is equal to:
f(-4) = 16 - 20 + 2 = 38
The final answer is 38.

Use the triangle inequality theorem to determine the smallest angle in the figure.
ZSCI
ZCIS
ZCSI
Lisc
Answer:
∠CIS.
Step-by-step explanation:
This angle is opposite from the smallest side. Therefore, according to the triangle inequality, it is the smallest angle.
The smallest angle that the angular momentum vector can make with the z-axis for an electron with quantum number l=2 is found using the magnetic quantum numbers. For m₁=+2, the angle would be the smallest, approaching 0 degrees.
Explanation:The question pertains to the calculation of the smallest angle that the angular momentum vector ℓ can make with the z-axis given the quantum number l for an electron. To find this, we use the concept of quantized angular momentum in quantum mechanics.
For an electron with a quantum number l=2, it can have multiple magnetic quantum numbers m₁, ranging from -l to +l. Therefore, for l=2, m₁ can be -2, -1, 0, 1, or 2. Each of these values corresponds to a different angle with the z-axis.
The smallest angle corresponds to the maximum value of m₁, which is 2 in this case. The formula cos 0 = Lz/L uses the magnetic quantum number m₁ and the total angular momentum to calculate the cosine of the angle. For m₁=+1, the value of cos 0 would be 0.707, using the provided ratios and simplifying the formulas given. This corresponds to an angle whose cosine is 0.707, which through the inverse cosine function can be determined to be approximately 45 degrees. However, for m₁=+2, the angle would be even smaller, approaching 0 degrees as the z-component of angular momentum becomes maximally aligned with the z-axis.

7. The sun is at an angle of elevation of 58º. A tree casts a shadow 20 meters long on
the ground. How tall is the tree?
The height of tree is 32 meter
Solution:
Given that, The sun is at an angle of elevation of 58 degree
A tree casts a shadow 20 meters long on the ground
The sun, tree and shadow forms a right angled triangle
The figure is attached below
ABC is a right angled triangle
AC is the height of tree
AB is the length of shadow
AB = 20 meters
Angle of elevation, angle B = 58 degree
By definition of tan,
[tex]tan \theta = \frac{opposite}{adjacent}[/tex]
In this right angled triangle ABC,
opposite = AC and adjacent = AB
Therefore,
[tex]tan\ 58 = \frac{AC}{AB}\\\\tan\ 58 = \frac{AC}{20}\\\\1.6 = \frac{AC}{20}\\\\AC = 1.6 \times 20\\\\AC = 32[/tex]
Thus height of tree is 32 meter
Final answer:
To determine the height of the tree using the angle of elevation of the sun and the shadow length, apply the tangent function. With an elevation of 58º and a shadow of 20 meters, the tree’s height is calculated to be approximately 33.94 meters.
Explanation:
To find the height of the tree given the angle of elevation of the sun and the length of the shadow it casts, we can make use of trigonometry. Specifically, we will use the tangent function, which relates the angle of elevation with the opposite side (the height of the tree) and the adjacent side (the length of the shadow).
Step-by-step solution:
Let's denote the height of the tree as H and the length of the shadow as 20 meters.The angle of elevation of the sun is given as 58º.Using the tangent function: tan(θ) = opposite/adjacent, where θ is the angle of elevation.Plugging in the values, we get tan(58º) = H / 20 meters.Solve for H by multiplying both sides by 20 meters: H = 20 meters · tan(58º).Use a calculator to find tan(58º), and then compute H.After calculating, we find that the height of the tree is approximately 33.94 meters.Thus, the height of the tree is approximately 33.94 meters.

Question 3
Answer: Choice A) {(3,4) (3,5)}-----------
Explanation:
Note how in choice A we have repeated x values
x = 3 pairs up with y = 4 and y = 5 at the same time.
The input x = 3 must only pair up with one output only if we want a function to happen.
If you plotted the points (3,4) and (3,5), it is possible to draw a vertical line through them. So this fails the vertical line test.
The other answer choices do not have repeated x values, so they are all functions.
==========================================
Question 4
Answer: choice A) 2x+3y = 10 and choice D) y = 18-----------
If you plotted choice A and choice D on an xy coordinate system, you should see straight lines forming.
2x+3y = 10 turns into y = (-2/3)x+10/3 which is y = mx+b form.
Choice D's equation is equivalent to y = 0x+18, so its slope here is 0, making it a flat horizontal line.
Choice B does not count as an answer because while it is a linear vertical line, it is not a function for similar reasons back in question 3. The fact that x = 16 pairs up with infinitely many y values is what makes this not be a function.
Choice C is not a linear equation. Instead it is a quadratic equation because the largest exponent is 2.

The total of 3 games is $38.97 . Each game costs the same amount. Write an equation that can be used to determine n , the cost of 1 game
Answer:
Step-by-step explanation:
3games cost38.97 so you have to divide 38.97divided by 3=12.99 so each game was 12.99 a game
To determine the cost of 1 game, set up an equation: 3n = $38.97. Divide both sides of the equation by 3 to isolate n. The cost of one game is $12.99.
Explanation:To find the cost of one game, we can set up the equation 3n = $38.97based on the given information. where n represents the cost of one game. Since each game costs the same amount, we can write the equation:
3n = $38.97
Divide both sides of the equation by 3:
n = $38.97 / 3
Dividing both sides of the original equation by 3 is a way to undo the multiplication by 3 on the left side, thereby isolating the variable n.
When we perform this division, we find that n is equal to $12.99.
n = $12.99
Therefore, the cost of one game is $12.99.

x+y= -3.........(2)
Making y as subject bin (2)
y = -3 - x
Substituting in (1)
5x + 2(-3 - x) = 9
5x - 6 - 2x = 9
3x = 9 + 6
3x = 15
x = 15/3
x = 5
And y = -3 - x
y = -3 - 5
y = -8
Answer:
The solution for the system of linear equations is x = 5, y = -8
Step-by-step explanation:
Let's solve the system of linear equations by substitution:
5x + 2y = 9
x + y = -3
Solving for x in the 1st equation, this way:
5x + 2y = 9
5x = 9 - 2y
x = (9 - 2y)/5
Substituting x in the 2nd equation:
x + y = -3
(9 - 2y)/5 + y = -3
9 - 2y + 5y = - 15 (Multiplying by 5 at both sides)
3y = - 15 - 9
y = -24/3
y = - 8
Substituting y in the 1st equation:
5x + 2y = 9
5x + 2 * - 8 = 9
5x - 16 = 9
5x = 25
x = 25/5 = 5
The solution for the system of linear equations is x = 5, y = -8

16. 5 = 3.5 + 0.5n - 0.5
16.5 = 3 + 0.5n
16.5 - 3 = 0.5n
13.5 = 0.5n
n = 13.5/0.5
n = 27
Therefore , it will take the cat (n-1) weeks to weigh 16.5 ounce, which will be 27 - 1 = 26
check:
3.5 + 26 ( 0.5)
= 3.5 + 13
= 16.5

The length of a rectangle is 3 1/6 cm longer than the width. The perimeter of the rectangle is 15 1/3 cm. What are the width and length of this rectangle?
The width of rectangle is [tex]2\frac{1}{4}\ cm[/tex] and length is [tex]5\frac{5}{12}\ cm[/tex]
Step-by-step explanation:
Let,
Width of rectangle = w
Length of rectangle = w+[tex]3\frac{1}{6}=w+\frac{19}{6}[/tex]
Perimeter of rectangle = [tex]15\frac{1}{3}=\frac{46}{3}\ cm[/tex]
Perimeter of rectangle = 2(Length + Width)
[tex]2(w+\frac{19}{6}+w)=\frac{46}{3}\\2(2w+\frac{19}{6})=\frac{46}{3}\\4w+\frac{19}{3}=\frac{46}{3}[/tex]
Subtracting [tex]\frac{19}{3}[/tex] from both sides
[tex]4w+\frac{19}{3}-\frac{19}{3}=\frac{46}{3}-\frac{19}{3}\\4w=\frac{46-19}{3}\\4w=\frac{27}{3}\\4w=9[/tex]
Dividing both sides by 4
[tex]\frac{4w}{4}=\frac{9}{4}\\w=\frac{9}{4}[/tex]
Therefore,
Width of rectangle = w = [tex]\frac{9}{4}=2\frac{1}{4}[/tex] cm
Length of rectangle = [tex]w+\frac{19}{6}=\frac{9}{4}+\frac{19}{6}=\frac{27+38}{12}=\frac{65}{12}=5\frac{5}{12}\ cm[/tex]
The width of rectangle is [tex]2\frac{1}{4}\ cm[/tex] and length is [tex]5\frac{5}{12}\ cm[/tex]
