Answer: Choice 2) sin(B) = cos(90-B)</h3>
Explanation:
The rule is that
sin(A) = cos(B)
if and only if A+B = 90.
Solving for A gets A = 90-B
So we end up with
sin(90-B) = cos(B)
which is the same as
cos(B) = sin(90-B)
Answer:
x = 2
Step-by-step explanation:
Answer:
first sub in (0,-2) to get
-2 = ab^0, but b^0 = 1
so a=-2
so far we have
y = -2b^x
now use the other point (2,-50)
-50 = -2(b^2)
b^2 = 25
b= ±5
however in exponentional equations the base is usually positve, so now you have
y = -2(5^x)
sub in x=-2 and you got it.

Answer:
P = 60 inches
Step-by-step explanation:
Perimeter is the distance around the outside of a shape. So, to find perimeter, add up all the sides.
The side lengths were given, add them:
15 + 20 + 25
= 60
The perimeter is 60 inches.
