8.57 i used the google calculator
It too would be tripled along with everything else.
From the given function, to explain the correct answer I will plot the graph for :
y(t)=-t^2+14t-40
thus the graph will be as shown in the figure:
From the graph we deduce that the correct statement is:
y'(t)=-2t+14=0
thus
t=7
thus
y(7)=0
thus the correct statement is:
<span>c. The average rate of change over the interval 6≤t≤8 is 0</span>
Answer:
Repeating
Step-by-step explanation:
11/3
11 ÷ 3 = .3666 this 6 repeats
Factor the equation out into (x-5)(x+3)
(x-5)=0
x=5
(x+3)=0
x=-3
x=5, -3
