A series of equal quarterly payments of $10,000 for 15 years is equivalent to what future worth amount at an interest rate of 6%
kogti [31]

Answer:

  $976,578.71

Step-by-step explanation:

We assume the deposits are made at the <em>beginning</em> of each quarter. The quarterly interest rate is 6%/4 = 1.5%. The number of quarterly payments is 15×4 = 60. The future value of an annuity due is ...

  A = P(1+r)((1+r)^n -1)/r

where r is the quarterly interest rate, n is the number of payments, and P is the payment amount.

  A = $10000(1.015)(1.015^60 -1)/.015 ≈ $976,578.71

The future value is $976,578.71.

Iris is building a model of the Washington Monument. Her model measures 15 in. tall and is 1.5 in. wide at the base. The actual
irina [24]
Using how tall it is over how wide
=>tall/wide
The model 15in/1.5in
The actual x/55ft

Convert everything into the same units so 55ft to inches
There are 12in in 1ft
55ft * 12in/1ft
The ft cross out leaving in
55*12in= 660 in

So
15in/1.5in = x/660in
Now solve for x my multiplying both side by 660in
660in *15in/1.5in=x
x= 6600in tall

A rocket is launched from a tower. The height of the rocket, y in feet, is related to the time after launch, x in seconds, by th
Hoochie [10]

Step-by-step explanation:

Given the height of the rocket y in feet related to time after launch x related by the equation:

Y=-16x^2+189x+79

The rocket will hit the ground when y = 0

The equation will become:

0=-16x^2+189x+79

Rearrange

-16x^2+189x+79 = 0

multiply though by minus

16x^2-189x-79 = 0

Factorize and solve for x:

x = 189±√189²-4(16)(-79)/2(16)

x = 189±√35721+5056/32

x = 189±√40777/32

x = 189±201.93/32

x = 189+201.93/32

x = 390.93/32

x = 12.22secs

hence the rocket will hit the ground after 12.22seconds (to the nearest hundredth of a sec)
