The situations that describe a quantity that changes in an exponential manner relative to the other quantity are,
A. The value of a printer decreases in value by 15% each year.
E. The amount of money in Devonte's savings account in it he earns 3.5% interest each year.
What are some rules of exponents?Some common rules of exponents are
xᵃ×xᵇ = xᵃ⁺ᵇ.
xᵃ/xᵇ = xᵃ⁻ᵇ.
Addition and subtraction of exponents is only possible for the same base value and when the base is different and both have the same exponent we just multiply the bases and write the exponent.
The situations that describe a quantity that changes in an exponential manner relative to the other quantity are,
The value of a printer decreases in value by 15% each year,
It is an exponentially decaying function.
Suppose the first year it decayed to 85% of it's original value, next year it will decay 15% of 85% of its value.
The amount of money in Devonte's savings account it he earns 3.5% interest each year.
Suppose he earned 3.5% for $100, which is 103.5, next year he will earn
3.5% on $103.5, an exponentially growing function.

Angelique makes 5 4/7 quarts of chili. She and her family eat 2 1/4 quarts. Will a 4-quart container hold the remaining chili?
Answer:
Yes
Step-by-step explanation:
The chilli remaining is:
5 4/7 - 2 1/4
[tex]5\frac{4}{7} - 2\frac{1}{4}[/tex]
=[tex]3\frac{16 - 7}{28}[/tex]
= [tex]3\frac{9}{28}[/tex]
3 9/28 is less than 4 quarts so the container would hold the remaining chilli

Find the slope of the line that contains (2, -10) and (-4, 2)
Answer:
slope=(2--10)/(-4-2)=12/-6=-2
The required slope of the line is -2.
Given that,
To find the slope of the line that contains (2, -10) and (-4, 2).
The slope of the line is a tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.
What is simplification?
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
The slope of any line is given as if two points are given,
m = [y₂ - y₁] / [x₂ - x₁]
the slope of the line that contains (2, -10) and (-4, 2)
m = [2 + 10 ] / -4 - 2
m = 12 / -6
m = -2
Thus, the required slope of the line is -2.

Answer:
B = 10.5
Step-by-step explanation:
From the figures, it looks like triangle HER is similar to triangle KPS.
From that we get
[tex] \dfrac{HE}{KP} = \dfrac{ER}{SP} [/tex]
[tex] \dfrac{B}{7} = \dfrac{7.5}{5} [/tex]
Multiply both sides by 7.
B = 10.5
Answer:
B = 10.5
C = 10
Step-by-step explanation:
When one divides the corresponding sides of similar triangles, one will attain the ratio of similitude. If one multiplies one of the similar triangle's sides by the ratio of similitude, then one will attain the corresponding side of the similar triangle. In simple terms, the ratio of similitude is the scaling factor between two similar polygons.
As per the given information, the two triangles are similar, therefore one can set up a proportion with their corresponding sides;
[tex]\frac{ER}{PS} = \frac{HE}{KP} = \frac{HR}{KS}[/tex]
Substitute;
[tex]\frac{7.5}{5} = \frac{B}{7} = \frac{15}{C}[/tex]
Solve for B with cross products;
[tex](7.5)(7) = (5)(B)\\52.5 = 5B\\10.5=B[/tex]
Solve with cross products for C;
[tex](7.5)(C) = (15)(5)\\7.5C = 75\\C=10[/tex]
