ANSWER
B) -1
EXPLANATION
From the graph,
f(1)=3 and f(4)=0.
The average rate of change from x=1 to x=4 of this function is,

Substitute the functional values

Simplify

The correct choice is .
6 * 2.5 = 15 That’s the area of the base
2.5 * 4 = 10
10 * 2 = 20
That’s the area of the 2 smaller sides
6 * 4 = 24
24 * 2 = 48
That’s the area of the 2 larger sides
Then you add all the dimensions together.
15+20+48 = 83.
So, the final equation is (6*2.5) + 2(2.5*4) + 2(6*4) = 83
I'm not sure that I am 100% right but I'll give it a shot.
50+75= 125*0.35=43.75
$43.75
14 divided by 20 is 0.7
Multiply that by 100
The answer is 70%
Answer: B) 70.50
Step-by-step explanation: john is buying 3 tickets for each of 2 movies total : 6 tickets each ticket costs 11.75
so 11.75*6
= 70.50
