Answer:
7/3
Step-by-step explanation:
f(x) = 3x^2 + 2x + 1, [0, 2]
f(0)=1
f(2)=17
f'(c)=f(2)-f(0)/2-1
f'(c)=17-1/1=16
f'(c)= 6x+2
6x+2=16
6x=16-2
6x=14
x=14/6
x=7/3
I am assuming that 114114 is actually 114.
Toni: 20 + 0.80/lap
Marcy: 15 + 0.85/lap
Marcy: x laps
Toni: 114x laps
[20 + 0.80(114x)] + [15 + 0.85x] = 257
20 + 91.2x + 15 + 0.85x = 257
92.05x = 257 - 35
92.05x = 222
x = 222/92.05
x = 2.41 laps
Marcy: x = 2.41 laps
Toni: 114x = 114(2.41) = 274.74 laps
20 + 0.80(274.74) = 20 + 219.79 = 239.79 or 240
15 + 0.85(2.41) = 15 + 2.05 = 17.05 or 17
240 + 17 = 257
Rectangle.
Explanation: Rectangles have four interior angles, all of which are right angles measuring 90 degrees each.
