H= 6g -4
h= -2g+28

6g -4 = -2g +28

8g -4 = 28
8g = 32
g= 4

h= 6(4)-4
24-4= 20

Joshua has $4,200 to invest for college. If Joshua invests $4,200 for 3 years and earns $630, what is the simple interest rate?
Rama09 [41]

Answer:

The simple interest rate is 5%.

This is possible with a rate of 6%, since in this case, his amount earned will be $5,208.

Step-by-step explanation:

This is a simple interest problem.

The simple interest formula is given by:

E = P*I*t

In which E is the amount of interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.

After t years, the total amount of money is:

T = E + P

Joshua has $4,200 to invest for college. If Joshua invests $4,200 for 3 years and earns $630, what is the simple interest rate?

We have that P = 4200, E = 630, t = 3. We have to find I.

E = P*I*t

630 = 4200*I*3

I = \frac{630}{4200*3}

I = 0.05

The simple interest rate is 5%.

Joshua’s goal is to have $5,000 after 4 years. Is this possible if he invests with a rate of  return of 6%?

We have to find T when P = 4200, t = 4, I = 0.06

So

E = P*I*t

E = 4200*0.06*4

E = 1008

T = E + P = 4200 + 1008 = 5208

This is possible with a rate of 6%, since in this case, his amount earned will be $5,208.

<u>Trigonometry</u>

[Right Triangles Only] SOHCAHTOA

[Right Triangles Only] sinθ = opposite over hypotenuse

Step-by-step explanation:

<u>Step 1: Identify Variables</u>

Angle θ = 23°

Opposite Leg = <em>x</em>

Hypotenuse = 21

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Substitute in variables [sine]:                                                                         \displaystyle sin(23^\circ) = \frac{x}{21}
  2. [Multiplication Property of Equality] Isolate <em>x</em>:                                              \displaystyle 21sin(23^\circ) = x
  3. Rewrite:                                                                                                           \displaystyle x = 21sin(23^\circ)
  4. Evaluate:                                                                                                         \displaystyle x = 8.20535
  5. Round:                                                                                                             \displaystyle x \approx 8.2
