Answer:
150
Step-by-step explanation:
h = hight
s = sides
surface = 10 x 15
surface = 150
(V = 10 x 10 x 15
(V = 100 x 15)
(V = 1500)
(Base area = B)
(B = Lenght x Width)
(B = 10 x 10)
(B = 100)
A.) according to the graph, Austin appears to be burning 10 calories per minute. If you look at a perfect point on the graph, which I chose (50,5) and you do x over y or calories per minute, you get a unit rate of 10 calories per minute.
b.) Since you have already found the unit rate in question a, your slope would be 10.

A=43
Answer:
2
Step-by-step explanation:
Given the function
f(x) = x^3 − x + 4 in the interval [1,2]
We are to find the value of x for which f(x) = 7
Substitute f(x) = 7 into the expression as shown!
f(x) = x^3 − x + 4
7 = x^3 − x + 4
x^3 − x + 4 -7 = 0
x^3 − x - 3= 0
x^3 -x = 3
x(x²-1) = 3
x²-1 = 3 and x = 3
x² = 3+1
x² = 4
x = ±√4
x = ±2
Since x lies within the interval, [1,2] hence the value of x is 2
