Answer:
Emily: 13, Peter: 9, Joshua: 18
Step-by-step explanation:
Emily = x
Peter = Emily - 4 = x - 4
Joshua = 2(Peter) = 2(x - 4)
Total = 40 = Emily + Peter + Joshua = (x) + (x - 4) + 2(x - 4)
40 = 2x - 4 + 2x -8
40 = 4x - 4 - 8
40 = 4x - 12
52 = 4x
x = 13
Emily = 13
Peter = 13 - 4 = 9
Joshua = 2(13 - 4) = 2(9) = 18
13 + 9 +18 = 40
Answer:
18
Step-by-step explanation:
Substitute 9 as y. 6(9-6). Subtract: 6(3). Multiply: 18
Answer:
cubic units
Step-by-step explanation:
Given is a function exponential as
The region bounded by the above curve, y =0 , x =13 is rotated about x axis.
the intersection point is at x=4
The limits for x are 4 and 13
The volume when rotated through x axis is found by
Here a = 4 and b =13
volume =
=.cubic units
Answer:

Answer:
i think it is 50ft but i'm not too sure
Step-by-step explanation:
