Answer:

(1) $11955.38

(2) $12228.62

(3) $12293.527

(4) $12326.6

Step-by-step explanation:

Compound interest is given by

A= P( 1 + r/n)^n*t

A= Final amount

P = initial amount = 6000

r = interest rate  = 9% = 0.09

n = number of times interest applied per time period

t = number of time periods elapsed

(1) Compounded annually

    n = 1 , t = 8

    A = 6000( 1+ 0.09/1) ^1*8

     A = 6000( 1.09) ^8 = $11955.38

(2) compounded quarterly

    n = 4 , t = 8

A = 6000( 1+ 0.09/4) ^4*8

     = 6000( 1.0225)^32 = $12228.62

(3) compounded monthly

     n = 12 , t = 8

 A = 6000( 1+0.09/12)^12*8 = $12293.527

(4) compounded continuously

       A = P* e^rt

      r = 0.09 , t = 8

           =  6000* e^0.09*8

           = 6000* e^0.72 = $12326.6

A road rises 50 feet over a horizontal distance of 600 feet. What is the slope of the road?
Hatshy [7]

Answer:

1/12 (or 0.833)

Step-by-step explanation:

Recall that the definition of "slope" is the change in vertical distance divided by the change in the horizontal distance. (aka. rise ÷ run)

it is given that rise = 50 feet and the horizontal distance (i.,e "run") = 600feet

hence slope = rise / run = 50 / 600 = 1/12 (or 0.833)

If 12,025 was invested at 3.25% compounded monthly 3 years, how much interest will be earned
wariber [46]

Answer:

$1,229.75

Step-by-step explanation:

Lets use the compound interest formula provided to solve this:

A=P(1+\frac{r}{n} )^{nt}

<em>P = initial balance</em>

<em>r = interest rate (decimal)</em>

<em>n = number of times compounded annually</em>

<em>t = time</em>

<em />

First, change 3.25% into a decimal:

3.25% -> \frac{3.25}{100} -> 0.0325

Since the interest is compounded monthly, we will use 12 for n. Lets plug in the values now:

A=12,025(1+\frac{0.0325}{12})^{12(3)}

A=13,254.75

Lastly, subtract A from P to get the interest earned:

13,254.75 - 12,025 = 1,229.75

Hi could someone just help me with this I'm not sure if i'm doing it correctly.
salantis [7]
Two angles are supplementary when they <span>add up to 180 degrees </span>⇒
m∠1 + m∠2 = 180°
4y + 7 + 9y + 4 = 180
13y + 11 = 180
13y = 180 - 11
13y = 169
y = 169/13
y = 13

m∠2 = 9y + 4 = 9 * 13 + 4 = 121°
