If 47400 dollars is invested at an interest rate of 7 percent per year, find the value of the investment at the end of 5 years f

Anni [7]

Answer:

Part A) Annual $\$66,480.95$

Part B) Semiannual $\$66,862.38$

Part C) Monthly $\$67,195.44$

Part D) Daily $\$67,261.54$

Step-by-step explanation:

we know that

The compound interest formula is equal to

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

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest in decimal

t is Number of Time Periods

n is the number of times interest is compounded per year

Part A) Annual

in this problem we have

$t=5\ years\\ P=\$47,400\\ r=0.07\\n=1$

substitute in the formula above

$A=\$47,400(1+\frac{0.07}{1})^{1*5}$

$A=\$47,400(1.07)^{5}$

$A=\$66,480.95$

Part B) Semiannual

in this problem we have

$t=5\ years\\ P=\$47,400\\ r=0.07\\n=2$

substitute in the formula above

$A=\$47,400(1+\frac{0.07}{2})^{2*5}$

$A=\$47,400(1.035)^{10}$

$A=\$66,862.38$

Part C) Monthly

in this problem we have

$t=5\ years\\ P=\$47,400\\ r=0.07\\n=12$

substitute in the formula above

$A=\$47,400(1+\frac{0.07}{12})^{12*5}$

$A=\$47,400(1.0058)^{60}$

$A=\$67,195.44$

Part D) Daily

in this problem we have

$t=5\ years\\ P=\$47,400\\ r=0.07\\n=365$

substitute in the formula above

$A=\$47,400(1+\frac{0.07}{365})^{365*5}$

$A=\$47,400(1.0002)^{1,825}$

$A=\$67,261.54$

Answer:

Step-by-step explanation:

Area of an equilateral triangle = $\frac{\sqrt{3}}{4} } a^{2}$

Sub in your value of 16ft

A = $\frac{\sqrt{3}}{4} } *16^{2}$

A = 110.85 $ft^{2}$

Algebraically solve the system of equations 2x + y = 5 and 5x − 2y = 8.

Tpy6a [65]

Answer:

x=2, y=1

Step-by-step explanation:

2x + y = 5

5x − 2y = 8.

Multiply the first equation by 2

2( 2x + y) = 5*2

4x +2y = 10

Add this to the 2nd equation to eliminate y

4x+2y = 10

5x -2y = 8

--------------------

9x = 18

Divide by 9

9x/9 = 18/9

x = 2

Now find y

2x+y = 5

2(2)+y = 5

4+y = 5

Subtract 4 from each side

y = 5-4

y =1

160% of what number is 144

givi [52]

Step-by-step explanation:

Let the number be x

160% of x=144

$160x \div 100 = 144$

then we cross multiply

$160x = 100 \times 144$

$160x = 14400$

divide both sides by 160

$160x \div 160 = 14400 \div 160$

$x = 90$

therefore the number is 90
