Answer: 72
Solution:
According to the question:-
S= 4 x 5 + 3 x 5 + 5 x 5 + 3 x 4
= 20 + 15 + 25 + 12
= 72
Answer:
x + 2y - 18 =0
y = x - 3 is x = 3
Step-by-step explanation:
Average rate of change can be calculated by the following
Δy/Δx
Our Δx refers to displacement.
Δx = 4 - 64 = -60
Our Δy refers to our Δf(x)
To get our f(x) values, we must plug in 64 and 4 into the function f(x)
f(64) = 8√64 = 64
f(4) = 8√4 = 16
Δf(x) = 16 - 64 = -48
So our rate of change is -60/-48 = 0.8
I believe the answer should be positive 0.8, but that's my best estimate.
The answer would be 8.6 I believe :)
