The volume, V, of a rectangular prism is determined using the formula V=lwh, where l is the length, w is the width, and h is the height of the prism.
Using this formula, what is the width of a rectangular prism that has a volume of 138.24 cubic inches, a height of 9.6 inches, and a length of 3.2 inches? Round to the nearest tenth.
0.2 inches
4.5 inches
46.1 inches
414.7 inches
Answer:
4.5inches
Step-by-step explanation:
Given the volume of a prism expressed as:
V =lwh where:
l is the length
w is the width,
h is the height of the prism.
Given
V = 138.24in³
h = 9.6in
l = 3.2in
w = ?
Substitute the given values into the formula to get the width
138.24 = 9.6*3.2*w
138.24 = 30.72w
w = 138.24/30.72
w = 4.5in
Hence the width of the rectangular prism is 4.5inches
The width of the rectangular pyramid that has a volume of 138.24 cubic inches, a height of 9.6 inches, and a length of 3.2 inches is 4.5 inches.
Volume of a rectangular pyramid:v = lwhwhere
l = length
w = width
h = height
v = 138.24 inches³
h = 9.6 inches
l = 3.2 inches
w = ?
138.24 = 9.6 × 3.2 × w
138.24 = 30.72w
w = 138.24 / 30.72
w = 4.5 inches

What is the effective annual rate for an APR of 10.60 percent compounded quarterly?
Answer:
The effective annual rate is 11.03%
Step-by-step explanation:
The effective interest rate is calculated through the formula:
[tex]r = (1 + i/n)^n - 1[/tex]
In this formula, r represents the effective interest rate, i represents the stated interest rate or APR, and n represents the number of compounding periods per year.
For a quarterly compounded interest, n=4. The APR i=10.60%=0.106
Given an APR r, the effective annual rate for a quarterly compound is:
[tex]r = (1 + 0.106/4)^4 - 1=1.0265^4-1[/tex]
[tex]r=1.11029-1=0.1103[/tex]
The effective annual rate is 11.03%

Which of the following exponential equations shows a reflection over the y-axis, a vertical
stretch by a factor of 2, and horizontal shift right 1.
a. y = -2(4)* – 1
b. y = -2(4):-1
c. y = 2(4)-x-1
d. y = 4(2)-x-1
Answer:
we are given
parent function as
(1)
vertical stretch of factor 2
so, we can multiply y-value by 2
then a shift right of 3 units
so, we can replace x as x-3
(2)
a shift left by 2 units
we can replace x as x+2
then a horizontal shrink factor of 1/2
so, we can multiply by 2 to x-value
then a shift down of 5 units
we can subtract y-value by 5
so, we get
(3)
a shift to the right 1 unit
we can replace x as x-1
stretched vertically by a factor of 1/2
we can multiply y-value by 1/2
then is shifted down 4 units
we can subtract y-value by 4
(4)
reflected across the x-axis
we can multiply y-value by -1
tretched vertically by a factor of 3
multiply y-value by 3
shifted left 7 units
we can replace x as x+7

Elijah is trying to make extra money on his summer vacation from school. He works two different jobs, earning $8 per hour babysitting and $10 per hour lifeguarding. How much money would Elijah earn in a week in which he worked 3 hours babysitting and 7 hours lifeguarding?
Answer:
$94
Step-by-step explanation:
8x + 10x = y
8 (3) + 10 (7) = y
24 + 70 = y
94 = y
Answer with step-by-step explanation:
If he were to work a full week, then 3 hours babysitting × 7 days a week × $8 for work = $168 for babysitting. 7 hours lifeguarding × 7 days a week × $10 for work = $490 for lifeguarding.
The total amount of money that Elijah would earn is $168 + $490 = $658

Find the axis of symmetry for this parabola:
y = -4x2 - 8x - 7
Answer:
Step-by-step explanation:
If we want to find the axis of symmetry of the parabola of [tex]y=-4x^{2} -8x-7,[/tex] we would use the formula of [tex]-\frac{b}{2(a)}[/tex] to find it.
b=-8
a=-4
so the formula would look like this [tex]-\frac{-8}{2(-4)}[/tex], simplify it >>>[tex]-\frac{-8}{-8}[/tex] which is -1
So -1 would be the axis of symmetry

what is a thesis statement?
Answer:
A thesis statement is a claim
Step-by-step explanation:
The thesis statement is the sentence that states the main idea of a writing assignment and helps control the ideas within the paper. It is not merely a topic. It often reflects an opinion or judgment that a writer has made about a reading or personal experience. For instance: Tocqueville believed that the domestic role most women held in America was the role that gave them the most power, an idea that many would hotly dispute today.
