Answer:
f(x) - 1
Step-by-step explanation:
guess one question will not hurt your grade.
I can only see part of the question can you repost it?!!
In order to combine, you have to multiply the top equation by 2
so you get
8g + 10h = 8
8g - 10h = 4
---------------
16g = 12
g = 3/4 --> plug it in to solve for h
8(3/4)-10h = 4
6-10h=4
10h=2
h=1/5
Your result: g=3/4, h=1/5
Csc (pi/2) or the cosecant of (pi/2) can be obtained by using a calculator.
In terms of degrees, pi/2 is equivalent to 90 degrees. Cosecant is also the reciprocal of sine. Since sin 90 is equal to 1, obtaining the reciprocal of 1 should yield csc (pi/2). Since the reciprocal is simply equal to 1, then:
