Bingel [31]2 years ago

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

If y varies directly with x when y=8,x=20 find the value of x when y=42
Alecsey [184]

The value of x is 105 when y=42

Step-by-step explanation:

A direct proportion means that the change in one quantity will also cause the change in other quantity

Given

y varies directly with x

x ∝ y

when the proportionality symbol is removed a proportionality constant is introduced

x=ky\\k=\frac{x}{y}\\Putting\ y=8\ and\ x=20\\k=\frac{20}{8}\\k = \frac{5}{2}\\So,\ the\ equation\ will\ be\\x=\frac{5}{2}y\\Putting\ y=42\\x=\frac{5}{2}*42\\x=5*21\\x= 105

The value of x is 105 when y=42

Keywords: Proportion, Direct variation

Help please? Suppose you have a normally distributed set of data pertaining to a standardized test. The mean score is 500 and th
Lina20 [59]
The formula to calculate the z-score of a certain value is:

z = (x - (mean))/(standard deviation)

In this example, the x-value is 450, the S.D. is 100, and the mean is 500.

So, substitute these values into the formula.

z = (450-(500))/100
z=-50/100
z=-0.5

Therefore, the z-score is -0.5.

How did they get the -5? I got -3
Naya [18.7K]
F(x) = x² - 3x
g(x) = √x - 1

f(g(x))= (√x - 1)² - 3(√x - 1) = (√x - 1)(√x - 1 - 3) =(√x - 1)(√x - 4) =
= √x √x -1*√x -4*√x +4 = x -5√x +4

Answer:  x -5√x +4

Write a linear equation in point-slope form for the line that goes through (1, -3) and (3,9).
dimaraw [331]
The slope of the line is 6, meaning that you can eliminate A,C. Since the point slope formula is y-y1=m(x-x1) you just need to see if the points are correct.

B. (3,9)
D. (1,-3)

While these do contain one point, substitute the coordinates to see which contain both.

B.

(1,-3): -3-9=6(1-3): -12=-12
(3,9): 9-9=6(9-3): 0= 6(6)

D.

(1,-3): -3+3=6(1-1): 0=6(0); 0=0
(3,9): 9+3=6(3-1): 12=6(2): 12=12

D is correct since the coordinate are on the line.
