I think it’s irrational because it does not end

The second option. The 5.5w part shows that its $5.50 times each window. The -3.25 is because he deducted 3.25 from the total. And then you have the price that he got on the other side.

Here's the work to find the windows in case you want it:
5.5w-3.25=35.25
5.5w=38.50
w=7
He washed 7 windows

Answer:

B and D

Step-by-step explanation:

$\frac{5}{6}$ × 13 = $\frac{5(13)}{6}$ = $\frac{65}{6}$ = 10 $\frac{5}{6}$ < 13

4 × 13 = 52 > 13

$\frac{3}{4}$ × 13 = $\frac{3(13)}{4}$ = $\frac{39}{4}$ = 4 $\frac{3}{4}$ < 13

$\frac{10}{10}$ × 13 = 1 × 13 = 13

Band D are equal to or greater than 13

I need help solving this problem. <img src="https://tex.z-dn.net/?f=4x%20cos%20%5E%7B-1%7D%20%282x%2B4%29-%20%5Csqrt%7B3-3%20x%5

Given:
$f(x)=4xcos^{-1}(2x+4)-\sqrt{3-3x^2}$

Using
$\frac{d}{dx}cos^{-1}(x)=-\frac{1}{\sqrt{1-x^2}}$
we derive
$\frac{d}{dx}4xcos^{-1}(2x+4)$
$=4cos^{-1}(2x+4)-\frac{8x}{\sqrt{1-(2x+4)^2}}$

Similarly, using
$\frac{d}{dx}\sqrt{x}=\frac{1}{2\sqrt{x}}$
we derive
$\frac{d}{dx}(-\sqrt{3-3x^2})$
$=\frac{3x}{\sqrt{3-3x^2}}$

Therefore, the derivative is
$f'(x)=\frac{d}{dx}(4xcos^{-1}(2x+4)-\sqrt{3-3x^2})$
$=4cos^{-1}(2x+4)-\frac{8x}{\sqrt{1-(2x+4)^2}}+\frac{3x}{\sqrt{3-3x^2}}$

8g+10=35 + 3g math 1

lilavasa [31]

Answer:

g= 5

Step-by-step explanation:

8g+10 = 35 + 3g

-3g -3g

5g+10=35

-10 -10

5g= 25

now divide 5 from both sides

5g/5= 25/5

g= 5
