What is the slope of a line that is perpendicular to 4x-8y=64
aleksley [76]

Answer:

- 2

Step-by-step explanation:

1) Write the equation in slope-intercept form.

4x - 8y = 64

-8y = -4x +64

y = 1/2 x - 8

slope of this line = 1/2

2) For perpendicular line the slope is negative reciprocal.

So, slope for perpendicular line is equal  -2.

Use the compound interest formulas A=P1+
Bingel [31]

The accumulated value of an investment if the money is a. compounded​ semiannually; b. compounded​ quarterly; c. compounded​ monthly; d. compounded continuously is $30731.4 $ , $30785.98  $30823.14 , 30841.95

<h3>What is Interest ?</h3>

Interest is the amount received by a person as a result of investing certain amount of money for a certain period of time.

It is given that

Principal = $ 25000

Time = 3 years

Interest Rate = 7 %

The amount is given by

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

Compounded semiannually

n = 2

Compounded Quarterly

n = 4

Compounded Monthly

n =12

Compounded Continuously

P = P₀ \rm e ^{rt}

Therefore the accumulated value for

compounded Semiannually is

\rm A = 25000( 1+ \dfrac{7}{200}) ^{2*3}

A = $30731.4

Compounded Quarterly

\rm A = 25000( 1+ \dfrac{7}{400}) ^{4*3}

A = $30785.98

Compounded Monthly

\rm A = 25000( 1+ \dfrac{7}{1200}) ^{12*3}

A = $30823.14

Compounded Continuously

\rm P = 25000 e ^{ 7 * 3 }

P = $30841.95

Therefore the accumulated value of an investment if the money is

a. compounded​ semiannually; b. compounded​ quarterly; c. compounded​ monthly; d. compounded continuously is

$30731.4 $ , $30785.98  $30823.14 , 30841.95

Sabrina rode on a ferris wheel at the state fair. in one rotation she traveled 778.72 ft. What is the appointment radius of the
adelina 88 [10]

The radius of ferris wheel is 124 feet

<em><u>Solution:</u></em>

Given that, Sabrina rode on a ferris wheel at the state fair

In one rotation she traveled 778.72 ft

To find: Radius of ferris wheel

The distance traveled in one rotation is equal to circumference of circle

Thus circumference of circle is equal to 778.72 feet

<em><u>The circumference of circle is given as:</u></em>

C = 2 \pi r

Where, "r" is the radius and \pi is a constant equal to 3.14

Substituting, C = 778.72

778.72 = 2 \times 3.14 \times r\\\\778.72 = 6.28r\\\\r = \frac{778.72}{6.28}\\\\r = 124

Thus radius of ferris wheel is 124 feet
