Barbara wants to restore her '66 Mustang in 4 years. She puts $200 into an account every month that pays 4.5% interest, compound

Tcecarenko [31]

Answer:

$10496.77

Step-by-step explanation:

We have been given that Barbara puts $200 into an account every month that pays 4.5% interest, compounded monthly.

To find the money in the account after 4 years, we will use future value formula.

$FV=R(\frac{1+\frac{r}{n})^{nt}-1}{\frac{r}{n}})$ , where,

R = Regular deposits,

r = Interest rate in decimal form

n = Number of times interest in compounded per year,

t = Time in years.

$4.5\%=\frac{4.5}{100}=0.045$

Substitute given values:

$FV=\$200(\frac{1+\frac{0.045}{12})^{12*4}-1}{\frac{0.045}{12}})$

$FV=\$200(\frac{1+0.00375)^{48}-1}{0.00375})$

$FV=\$200(\frac{1.00375)^{48}-1}{0.00375})$

$FV=\$200(1.1968143774194609-1}{0.00375})$

$FV=\$200(0.1968143774194609}{0.00375})$

$FV=\$200(52.4838339785229066667)$

$FV=\$10496.76679570458133334$

$FV\approx \$10496.77$

Therefore, there will be an amount of $10496.77 in the account after 4 years.

The radius of a cylinder is 3.5 ft. The height is 14 ft. Find the surface area and volume of the cylinder to the nearest tenth o

ICE Princess25 [194]

Given:
radius : 3.5 ft
height : 14 ft

Surface Area of a cylinder = 2πrh + 2πr²
S.A. = 2 * 3.14 * 3.5ft * 14ft + 2 * 3.14 * (3.5ft)²
S.A. = 307.72ft² + 2 * 3.14 12.25ft²
S.A. = 307.72ft² + 76.93ft²
S.A. = 384.65 ft²

Volume of a cylinder = πr²h
V = 3.14 * (3.5ft)² * 14ft
V = 3.14 * 12.25ft² * 14ft
V = 538.51 ft³

Answer:

The smallest model - bottom right - in the question diagram represents $\sqrt[3]{64}=4$ .

Step-by-step explanation:

Considering the radical expression

$\sqrt[3]{64}$

Lets simply this radical expression first

As

$\sqrt[3]{64}$

$\mathrm{Factor\:the\:number:\:}\:64=4^3$

$=\sqrt[3]{4^3}$

$\mathrm{Apply\:radical\:rule}:\quad \sqrt[n]{a^n}=a,\:\quad \:a\ge 0$

$\sqrt[3]{4^3}=4$

$=4$

Therefore, $\sqrt[3]{64}=4$

Now, as we can determine that $\sqrt[3]{64}=4$ . So, the smallest model in the question diagram represents $\sqrt[3]{64}=4$ as each face of the cube of the smallest model in the diagram - bottom right - has 4 squares.

Therefore, the smallest model - bottom right - in the question diagram represents $\sqrt[3]{64}=4$ .
