Corey invested $1500 when he was a freshman in order to save for college. If he chooses to invest it in an account that earns 3.

Tcecarenko [31]

Answer: He will have $1721.28. after 4 years.

Step-by-step explanation:

The formula we use to find the compounded amount A is :

$A=P(1+r)^t$ , where P= principal value, r = rate of interest , t= time.

As per given , we have

P=$1500 , r=3.5%=0.035 , t= 4 years

Money he will have after 4 years = $1500(1+0.035)^4$

$=1500(1.035)^4\\\\=1721.28450094\approx1721.28$

Hence, he will have $1721.28. after 4 years.

miv72 [106K]

Answer:

The equation of the line normal to the curve of y=cos1/3x, where x=pi is y= 2√3 x - 10.38

Step-by-step explanation:

The equation of the normal to the curve is

Y- y1 = - 1/m (x- x1)

Where m is the gradient.

A cylinder with radius r and height 2r+4 contains a cube with edge length r + 2, as shown.

marishachu [46]

Volume is the amount of space in an object. The fraction occupied by the cube is: $\frac{r\sqrt2}{\pi(r + 2)}$

First, we calculate the volume of the cube.

$Volume = Length^3$

From the figure, we have:

$Length = r\sqrt 2$

So:

$V_1 = (r\sqrt2)^3$

$V_1 = (2\sqrt2)r^3$

Next, the volume of the cylinder

$Volume=\pi r^2h$

So, we have:

$V_2 = \pi r^2 (2r + 4)$

The fraction (n) occupied by the cube is:

$n = \frac{V_1}{V_2}$

So, we have:

$n = \frac{(2\sqrt2)r^3}{\pi r^2(2r + 4)}$

Factor out 2 in the denominator

$n = \frac{(2\sqrt2)r^3}{2\pi r^2(r + 2)}$

Cancel out common terms

$n = \frac{r\sqrt2}{\pi(r + 2)}$

<em>Hence, the fraction occupied by the cube is: </em> $\frac{r\sqrt2}{\pi(r + 2)}$ <em />
