Answer:

1.5 ft

Step-by-step explanation:

Use the Pythagorean theorem and rearrange it to find the third length.

3.6^2 + x^2 = 3.9^2

3.9^2 - 3.6^2 = x^2

15.21 - 12.96 = 2.25

sqrt 2.25 = 1.5

x = 1.5

pav-90 [236]

Answer:

cost is $4183.87

Step-by-step explanation:

given data

time t = 5 year

amount A = $1000

rate r = 6.25 % = 0.0625

to find out

how much it will cost

solution

we will apply here formula for present value of annuity that is express as

present value = amount × $\frac{1-(1+r)^{-t}}{r}$ ....................1

put here all these value we get cost we will pay

present value = amount × $\frac{1-(1+r)^{-t}}{r}$

present value = 1000 × $\frac{1-(1+0.0625)^{-5}}{0.0625}$

present value = 4183.869221

so cost is $4183.87
