Answer:

3a^2 - 7a - 6

Step-by-step explanation:

Find the average length of the light gray shaded figure. It is:

4a + 5 + 2a - 1 6a + 4

--------------------- = --------------- = 3a + 2

2 2

Now multiply this average length, 3a + 2, by the width, a - 3:

Area of light gray figure is (3a + 2)(a - 3) = 3a^2 - 7a - 6

Charlie deposits $250 on the last day of each month into an account that earns 6% annual interest compounded monthly. Complete t

Ierofanga [76]

Answer:

A=$265.42

Step-by-step explanation:

The formula to apply here is;

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

where;

A=amount at the end

P=principal amount=$250

r=rate of interest=0.06%

n=number of compounding per year=12

t=total number of years=1

$A=250(1+\frac{0.06}{12} )^{12*1} \\\\A=250(1.005)^{12}\\ \\\\A=265.42$

Which of these is a point-slope equation of the line that is perpendicular to y – 3 = 4(x – 10) and passes through (–3, 7)? A. y

love history [14]

So, we know the slope of the original equation is 4. So the perpendicular slope is the negative reciprocal, so it's -1/4. Then, the points have to be -3, 7. So when we plug that into our equation, we get

$Y-7 = -\frac{1}{4}(x--3)\\ Y-7=-\frac{1}{4}(x+3)$
