What is an exponential function?Mathematical functions with exponents include exponential functions. f(x) = bˣ, where b > 0 and b 1, is a fundamental exponential function.
Given:
The function c(x) = 72 ⋅ (1.04)ˣ models the cost in dollars, c, of 1 ounce of a certain chemical used in a laboratory.
x represents the number of years since 2010.
An ounce of the chemical cost in 2018 is,
= 72 × (1.04)⁸
= $98.54
Therefore, the cost is $98.54.

The formula for centripetal acceleration, a, is given by this formula, where v is the velocity of the object and r is the object’s distance from the center of the circular path:
a=v^2/r
.
Solve the formula for r.
Answer:
Step-by-step explanation:
For this case we have the following equation:
a = v ^ 2 / r
From here, we must clear the value of speed.
We have then:
v ^ 2 = a * r
v = root (a * r)
Answer:
the formula for the velocity is:
v = root (a * r)

what is the value of x?
Answer:
x = 6
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
[tex]\frac{FG}{MN}[/tex] = [tex]\frac{GH}{NP}[/tex] , substitute values
[tex]\frac{12}{x}[/tex] = [tex]\frac{20}{10}[/tex] = 2 ( multiply both sides by x )
12 = 2x ( divide both sides by 2 )
6 = x

A woman has 31 coins in her pocket, all of which are dimes and quarters. If the total value of the coins is $ 5.65, how many dimes and how many quarters does she have?
Answer:
14 dimes and 17 quarters
Step-by-step explanation:
d and q are the number of dimes and quarters, respectively.
"31 coins, all of which are dimes and quarters."
d+q = 31
d = 31-q
"the value of the coins is $5.65"
0.10d + 0.25q = 5.65
substitution
0.10(31-q) + 0.25q = 5.65
3.10-0.10q + 0.25q = 5.65
0.15q = 2.55
q = 17
d = 31-q = 14
14 dimes and 17 quarters

Give answer plzz
yes here x and y are directly proportional when looking at the x-coordinate
Step-by-step explanation:
here,
x1=7, y1=14
x/y=7/14
=1/2.
when considering the second coordinates,
X2=9/18=we will get the answer again
1/2.
all the coordinates is proportional in this form it is all will get the answer one by two so this x -axis and y-axis are directly proportional

pls give me the height only!!
Answer: Height = 41 in
Step-by-step explanation:
Alrighty, I was trying to dodge this question but I guess I'll have to split my brain cells.
To find the Height we can turn the information we have into an equation
15,577.54 = 3.14 * 11 ^ 2 * h
we do some distrubutive property
15,577.54 = 3.14 * 121 * h
15,577.54 = 379.94 * h
15,577.54 = 379.94h
divide by 379.94
H = 41
THE HEIGHT IS 41 YAY ( My head hurts )

You already have two points so that's what we'll use.
(4, 7) (12, 17)
17 - 7
12 - 4 = 10/8

Find the perimeter of an isosceles triangle whose base is 16 cm and whose height is 15 cm.
Answer:
50 cm
Step-by-step explanation:
The altitude from the vertex to the base bisects the base and divides the triangle into 2 right triangles.
Using one of the right triangles with legs 8 and 15 , then hypotenuse h is
h² = 8² + 15² = 64 + 225 = 289 ( take the square root of both sides )
h = [tex]\sqrt{289}[/tex] = 17
The 2 congruent sides of the isosceles triangle are 17 cm
Then the perimeter P is
P = 17 + 17 + 16 = 50 cm
