Answer:
9.74 feet
Step-by-step explanation:
the formula for finding a hypotenuse is 
. We can rearrange that to get: 
. So: 49 + b^2 = 144. We get the square root of 95, AKA around 9.74.
Dividing by a fraction is like multiplying with the inverse.
So 14 / (2/7) is the same as 14 * 7/2, which is 49
Answer:
90.3125 cm³
Step-by-step explanation:
Since the perimeter of the bottom square is 17, you can divide by four to find out what the lenght of each side is.
17/4=4.25 cm
We know the height of pyramid is 15 cm
The formula for the volume of a square pyramid is
V=a²(h/3)
V=a2(h/3)=4.252·15/3=90.3125 cm³
Answer:
1,8 and 5,10
Step-by-step explanation:
Answer:
average rate of change is 3/2
Step-by-step explanation:
Recall that the average rate of change in an interval [x1, x2], is defined as:
[f(x2)-f(x1)] / (x2 - x1)
which for the interval [0, 2] becomes:
[f(2)-f(0)] / (2 - 0)
From the graph we read that f(0)= 1 and f(2) = 4, therefore:
[f(2)-f(0)] / (2 - 0) = [4 - 1] / 2 = 3/2
