Step-by-step explanation:
sin∅ = opposite / hypotenuse
Answer:
sin(K) = 48/50
sin(P) = 14/50
Answer: second option
Step-by-step explanation:
To find the inverse function of the given function f(x):

You need to:
Substitute
into the function:

Now, you need to solve for "x", to do this, you must divide both sides of the function by 2:

Now, replace "x" with "y" and replace "y" with "x":

Therefore, substituting
you get:
or 
Answer:
a = -5
b = 2
Step-by-step explanation:
a+b=-3
<u>a-b= -7</u> +
2a = -10
a = -10/2
a = -5
a + b = -3
-5 + b = -3
b = -3 + 5
b = 2
