Answer:
1) 0, 180
2) 90
3) 3pi/2
4) pi/2, -3pi/2
5) 90, 270
6) 0
7) pi
8) -2pi, 0, 2pi
Step-by-step explanation:
1) sinx = 0
x = 0, 180, 360
2) sinx = 1
x = 90
3) sinx = -1
x = 270 or 3pi/2
4) sinx = 1
x = pi/2, pi/2 - 2pi = -3pi/2
5) cosx = 0
x = 90, 360
6) cosx = 1
x = 0, 360
7) cosx = -1
x = pi
8) cosx = 1
-2pi, 0 , 2pi
6
2+x=8
Subtract 2 on both sides
x=6
Answer:
The correct answer is A) 2
Step-by-step explanation:
In order to find this, input 1 into the equation for each value of x that you see.
f(x) = x^2 + 3x - 2
f(1) = 1^2 + 3(1) - 2
f(1) = 1 + 3 - 2
f(1) = 2
Answer:
x^2+4x-32=0
(mid-term breaking---4 x 8=32)
x^2+8x-4x-32=0
x(x+8)-4(x+8)
x+8=0 or x-4=0
So x=+4 or x=-8
Step-by-step explanation:
Answer:
14
First multiply
1 and 3/4 by 8 and then you got your answer
