The law of sines can be used to find the missing side lengths.

... RP = sin(60°)/sin(45°)·10 = 10√(3/2) ≈ 12.247

... PS = sin(75°)/sin(45°)·10 ≈ 13.660

Then the perimeter is

... perimeter = RS + RP + PS

... = 10 + 12.247 + 13.660 ≈ 35.91 . . . .units

Which of the following is the graph of:<br>(x-3)^2+(y+1)^2=9?

Marianna [84]

<h3>Answer: Choice A</h3>

center = (3, -1)

radius = 3

==================================================

Explanation:

Rewrite the y+1 as y-(-1). Rewrite the 9 as 3^2

Then compare to the general form (x-h)^2+(y-k)^2 = r^2

You should find that h = 3, k = -1 and r = 3.

The center is (h, k) = (3,-1) and the radius is r = 3.

Choice A matches with that description.

Find the range for the set of data 24, 30, 17, 22, 22

OverLord2011 [107]

$\huge\text{Hey there!}$

$\huge\textbf{Question reads....}$

$\text{Find the range for the set of data 24, 30, 17, 22, 22}$

$\huge\textbf{What does \boxed{range} mean in math?}$

$\boxed{Range}\rightarrow\text{is the DIFFERENCE between the biggest number and the}\\\text{smallest number.}$

$\huge\textbf{How do you find the \boxed{range}?}$

$\text{You find the biggest number \& subtract it from the smallest number.}$

$\huge\textbf{Equation:}$

$\text{24, 30, 17, 22, 22}$

$\huge\textbf{The \boxed{\mathsf{\mathsf{biggest}}} number }\huge\boxed{\downarrow}$

$\text{30}$

$\huge\textbf{The \boxed{\mathsf{\mathsf{smallest}}} number }\huge\boxed{\downarrow}$

$\text{17}$

$\huge\textbf{Equation:}$

$\rm{30 - 17}$

$\huge\textbf{Simplify it:}$

$\large\text{Start at 30 and go DOWN 17 spaces to the \boxed{left} and you will}\\\large\text{have your answer. }$

$\huge\textbf{Therefore, your answer should be:}$

$\huge\boxed{\mathsf{13}}\huge\checkmark$

$\huge\text{Good luck on your assignment \& enjoy your day!}$
