Answer:
4x=32
or,x=32/4
therefore,x=8
Answer:
it is D because you would need to divide both numbers by 4 to get x by itself and 32 divided by 4 is 8 so X=8

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

The answer is C, reflection over the y-axis.
Step-by-step explanation:
It is reflection because everything was flipped over the y-axis.
The conversion of ammonium cyanide to urea is a second-order reaction. This means that the concentration C of ammonium cyanide at time t is given by 1/C = kt + 1/C0, where C0 is the initial concentration and k is the rate constant. Assume the initial concentration is known to be 0.1 mol/L exactly. Assume that time can be measured with negligible uncertainty.
a. After 45 minutes, the concentration of ammonium cyanide is measured to be 0.0811 ? 0.0005 mol/L. Estimate the rat? constant k, and find the uncertainty in the estimate.
b. Use the result in part (a) to estimate the time when the concentration of ammonium cyanide will be 0.0750 mol/L, and find the uncertainty in this estimate.

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.

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%
In the following diagram which is not drawn to scale, why can't both line AB and line AC be perpendicular to line BC?
Answer:
AC and AB both can't be perpendicular to line BC because if they were, then AB and AC would be parallel to each other and would never intersect. In this diagram, AB and AC intersect, so it it not possible.
Perpendicular lines meet at a right angle.
AB and AC cannot be perpendicular to BC because AB and AC are not parallel
From the diagram, we can see that line AB and line AC intersects at point A.
This means that both lines are not parallel
For any two lines to be perpendicular to a third line, the two lines must be parallel to each other.
So, we can conclude that:
Lines AB and AC cannot be perpendicular to line BC because both lines are not parallel.

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
