Answer:
51. A/P = (2.2t +25)/(2.6t +29)
52. A/P for t=0 is about 0.862
A/P for t=4 is about 0.858
Step-by-step explanation:
51. The ratio of the two given functions is ...
r(t) = A/P
r(t) = (2.2t +25)/(2.6t +29)
__
52. Fill in the required numbers and do the arithmetic.
r(0) = (0 +25)/(0 +29) = 25/29
r(0) ≈ 0.862
_
r(4) = (2.2·4 +25)/(2.6·4 +29) = 33.8/39.4
r(4) ≈ 0.858
The salary ratio is approximately flat at 0.86 over the 4-year period. It is declining slightly each year.
Part a.
<span>The perimeter formula is: </span>P = 2w + 2L
Your answer for part A is P = 2w + 2L
Part b.
They tell us in part b, that:
w = 6L + 20
Substitute that into what we got for part a.
P = 2(6L + 20) + 2L
P = 12L + 40 + 2L
P = 14L + 40
Your answer for partb is P = 14L + 40
Part c.
So we take what we got from part b, and solve for L.
P = 14L + 40
14L = P - 40
That is your answer for part 3 ^
part d.
Plug in w = 32 into what we first got in part b.
w = 6L + 20
32 = 6L + 20
6L = 12
L = 2
Your answer for part d is L = 2

<span>The perimeter formula is: </span>P = 2w + 2L
Your answer for part A is P = 2w + 2L
Part b.
They tell us in part b, that:
w = 6L + 20
Substitute that into what we got for part a.
P = 2(6L + 20) + 2L
P = 12L + 40 + 2L
P = 14L + 40
Your answer for partb is P = 14L + 40
Part c.
So we take what we got from part b, and solve for L.
P = 14L + 40
14L = P - 40
That is your answer for part 3 ^
part d.
Plug in w = 32 into what we first got in part b.
w = 6L + 20
32 = 6L + 20
6L = 12
L = 2
Your answer for part d is L = 2
