thw answer is c if you count the blocks
Answer:
144m
Step-by-step explanation:
To find the area of trapezoidal prism, you would have to multiple the area of the trapezoid by the height of the prism.
The formula for trapezoid is 1/2(L+W) x H
So the area of trapezoid would be 1/2(10+6) x 2 = 16
The height is 9m so it would be 16 x 9, which is 144m
Normallly people want miles per hour or miles/hour
so divvided 420 by 7 =420/7=60/1=60 miles per hour
Answer:
Average rate of change for the function 
over the interval -1<x<1 is -1
Step-by-step explanation:
We need to find average rate of change of f over the interval -1 < x < 1
The function given is:
The formula used to find average rate of change is:
We have, a = -1 and b = 1
Finding f(b) when b=1
Now, finding f(a), when a= -1
Now, putting values and finding average rate of change
So, average rate of change for the function over the interval -1<x<1 is -1
Let's plug in x = 2.
f(x) = x^2
f(2) = 2^2 ... replace every x with 2
f(2) = 4
----------
Now plug in x = 3.
f(x) = x^2
f(3) = 3^2 ... replace every x with 3
f(3) = 9
-----------
And x = 5 as well.
f(x) = x^2
f(5) = 5^2 .... replace every x with 5
f(5) = 25
-----------
We see that
f(2)+f(3) = 4+9 = 13
which is not equal to f(5) = 25.
So f(2)+f(3) = f(5) is false.
------------
Another way to phrase why it doesn't work is because (2,3,5) isn't a pythagorean triple. The equation 2^2+3^2 = 5^2 is false.
If it said f(3)+f(4) = f(5), then it would be correct because 3^2+4^2 = 5^2 is a true equation.
