Answer:

52cm^2

Step-by-step explanation:

I did the splitting in my head and that's pretty hard to explain like this so, just BTW if your confused on where I got my lengths from.

(7*6) + (5*2)

(42) + (10)

I separated them into an almost square and a rectangle, then I found the area of each rectangle and then added them together.

Hopefully this was useful and you didn't have any issues with this!

a person invests 9000 dollars in the back. The back pats 4.75% interest compounded quarterly. To the tenth of a year, how long m

MaRussiya [10]

Answer:

5.7 years

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

in this problem we have

$t=?\ years\\ P=\$9,000\\A=\$11,800\\r=4.75\%=4.75/100=0.0475\\n=4$

substitute in the formula above

$11,800=9,000(1+\frac{0.0475}{4})^{4t}$

Solve for t

$\frac{11.8}{9} =(1.011875)^{4t}$

Applying property of exponents

$\frac{11.8}{9} =(1.011875^{4})^{t}$

Applying log both sides

$log(\frac{11.8}{9})=log[(1.011875^{4})^{t}]$

$log(\frac{11.8}{9})=(t)log[(1.011875^{4})]$

$t=log(\frac{11.8}{9})/log[(1.011875^{4})]$

$t=5.7\ years$

The initial value is where the line intersects the y-axis. So, this does it at y = 2. The graph has a slope (rate of change) of 1, because for every x-value, the y-value goes up by exactly 1. So, the answer is C.

A missile is fired at an angle of 75 from the horizontal. At one point, its speed was 900 mph. Find its horizontal velocity in m

mezya [45]

Hello Chrisd117991999.

If the missile was going 900mph and we are trying to find the horizontal velocity

This could be 3.88, and rounding it to the nearest hundredth would be <u><em>3.90 miles per minute</em></u>
