L. The width, w, of the rectangle is 10 inches. What is the perimeter of the rectangle?

1 answer:

40 inches because a rectangle has 2 sets of parallel lines and if the width and length are 10 then you just have to add up all the sides.

Use a graphing calculator to solve the equation -2sin(theta)= 1.2 in the interval from 0 to 2pi.

Answer:

$\theta=\pi +arcsin(\frac{3}{5})\approx 3.785\\\\\theta=2\pi -arcsin(\frac{3}{5} ) \approx 5.64$

Step-by-step explanation:

As you can see from the graph I attached you, the possible solutions in the interval from 0 to 2π are approximately:

$\theta=3.7\\\\and\\\\\theta=5.7$

So, it's useful to solve the equation too, in order to verify the result:

$-2sin(\theta)=1.2\\\\sin(\theta)=-\frac{3}{5}$

Taking the inverse sine of both sides:

$\theta=\pi +arcsin(\frac{3}{5})\approx 3.785\\\\\theta=2\pi -arcsin(\frac{3}{5} ) \approx 5.64$

Using this result we can conclude the solutions in the interval from 0 to 2π are approximately:

$\theta\approx 3.785\\\\\theta \approx 5.64$

Total number of days =300

day =300

Seller credit =?

Formula:

$\bold{\text{Seller credit} = \frac{\text{total tax} \times \text{number of days}}{\text{day}}}$

$= \frac{960 \times 300}{360}\\\\= \frac{32 \times 300}{12}\\\\= 8 \times 100\\\\=800$

Answer: 140

Step-by-step explanation: since 4 = 40 then 2 would also be 40 because they are the same angle (Keep in mind that a line is 180 degrees) 180-40=140! Good luck! :D
