It is given that f(t) = -16t² + 32t + 90
<span>The average rate of change will be calculated as following
</span>
At t₁ = 4 ⇒⇒⇒ f(t₁) = -16*(4)² + 32*(4) + 90 = -38
At t₂ = 6 ⇒⇒⇒ f(t₂) = -16*(6)² + 32*(6) + 90 = -294
∴
<span>So, The average rate of change of f(t) from t = 4 seconds to t = 6 seconds is
128 feet per second .

First what your gonna do is find the slope. So y2-y1/x2-x1 so 17-12/220-120= 5/100 so 1/20. Then you have to put that into slope intercept form. So y=1/20x + b. Then plug in points for x and y. I’ll use 12 and 120. So 12 = 1/20(120)+ b = 12=6+b then subtract 6 from both sides to get b= 6. So your answer is y= 1/20x +6
40 is 1 tenth because 40 x 10 is 400
Answer:
Step 3 i think because 10-7+7=13 because if u do that problem u actually get 10 instead of 13
Step-by-step explanation:
because 10-7+7=13 because if u do that problem u actually get 10 instead of 13
