Suppose your friend's parents invest 15,000 in an account paying 7% compounded annually. What will the balance be after 5 year

meriva

Answer:

FV= $21,038.28

Step-by-step explanation:

Giving the following information:

Initial investment (PV)= $15,000

Interest rate (i)= 7% compounded annually

Number of periods (n)= 5

To calculate the future value (FV), we need to use the following formula:

FV= PV*(1 + i)^n

FV= 15,000*(1.07^5)

FV= $21,038.28

The generic equation of the line is:

$H-H0 = m (T-T0)$

Where,

m: slope of the line

(T0, H0): ordered pair belonging to the line.

The slope of the line is:

$m =\frac{H2-H1}{T2-T1}$

Substituting values we have:

$m =\frac{15-17}{5-3}$

Rewriting:

$m =\frac{-2}{2}$

$m = -1$

Then, choosing an ordered pair we have:

$(T0, H0) :( 5, 15)$

Substituting values we have:

$H-15=-(T-5)$

Rewriting the equation:

$H-15=-T+5$

$H=-T+5+15$

$H=-T+20$

Then, for 8 hours we have:

$H=-8+20$

$H=12$

Answer:

a linear equation to model the relationship between height H of the candle, and T time is:

$H=-T+20$

the candle will be 12 inches after burning 8 hours

Find the value of x 12x 6x+28 Your answer

Irina18 [472]

Step-by-step explanation:

Hey there!

By looking at the figure, the given "2x" and "6x + 28" are co-interior angle.

So,

2x + 6x + 28 = 180°. ( sum of co-interior angle is 180°)

8x + 28°=180°

8x = 180° - 28°

8x = 152°

$x = \frac{152}{8}$

X = 19°

Therefore, X = 19°.

Hope it helps...
