Answer:

4/5

Step-by-step explanation:

In a right triangle, the longest side is always the hypotenuse. Hence

Hypotenuse =5cm

The side opposite to the angle theta is the opposite, hence

Opposite = 4cm

Required

Sin theta

According to SOH CAH TOA

Sin theta = opposite/hypotenuse

Sin theta = 4/5

Hence the sine of the angle opposite the side of length 4cm is 4/5

Which equation can be used to find the answer? Camilla needs $65 for a pair of hiking shoes. She already has $19 saved. How much
r-ruslan [8.4K]
The answer is a. n+19=65 n=46 $46. To find out how much more she needs to save, you would add that amount with 19 to get a total of 65. So your equation would be n+19=65. Then once you have your equation, solve it. Subtract 19 from both sides to get n by itself.
n+19=65
-19 -19
n=46
So your answer for how much more she needs to save is $46.

Solve this and get 30 points !!!!!

First of all, don't let "b" confuse you. Know that b = 5/6k = -10, so all you really have to solve for this problem is \frac{5}{6}k = -10.

Before anything else, you have to isolate k. Do this my multiplying both sides by the reciprocal of 5/6.

\frac{6}{5} * \frac{5}{6}k = -10 * \frac{6}{5}

The 6/5 and 5/6 cancel each other out, so we are left with k = -10 * \frac{6}{5}

--> k = \frac{-10 * 60}{5}

---> \frac{-60}{5} = -12

So k = -12.

Hope this helped. Good luck.

Asap<br> Select the correct answer.<br> Which function has a restricted domain?
german

Step-by-step explanation:

Check second one

\\ \rm\Rrightarrow k(x)=(-x+3)^{\frac{1}{2}}

  1. 1/2 means square root

\\ \rm\Rrightarrow \sqrt{(-x+3)}

So

\\ \rm\Rrightarrow -x+3>0

\\ \rm\Rrightarrow -x>-3

\\ \rm\Rrightarrow x

Hence.

Domain is restricted

Option B is correct
