Noah wants to buy a 5 year annuity that pays $1000 at the end of each year, starting one year from now. It earns interest at 6.2

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

Sharon kicks a ball from the ground into the air with an upward velocity of 64 feet per second. The function h = -16t2 + 64t mod

pychu [463]

To find when the ball reaches the ground, you would need to find the time that gives you a height value of zero.

Your answer would be 4 seconds

h = -16(4)^2 + 64(16)
h = -16(16) + 256
h = -256 + 256
h = 0

Hope this helps!

Which step brings you closest to getting the variable alone on one side of the equation

Oliga [24]

Answer:

Adding 5 from both sides then dividing by 7

Step-by-step explanation:

The best way to isolate x is to add 5 to both sides first:

21 = 7x

Then to isolate x by itself divide both sides by 7

x = 3

That would be the value of x and your final answer.
