It would be the first one
Step-by-step explanation:
-- Supplementary angles add up to 180 degrees.
48 + S = 180
S = 180 - 48 = <em>132 degrees</em>
-- Complementary angles add up to 90 degrees.
48 + C = 90
C = 90 - 48 = <em>42 degrees</em>
7π/12 lies in the second quadrant, so we expect cos(7π/12) to be negative.
Recall that
which tells us
Now,
and so
Answer:
f(x)=3x^2+2x-10 if x=2
f(x)=3(2)^2+2(2)-10
f(x)=3(4)+2(2)-10
f(x)=12+4-10
f(x)=16-10
f(x)=6
g(x)=3x-3 if g(x)=2
g(x)=3(2)-3
g(x)=6-3 =3
Step-by-step explanation:
<u>f</u><u>(</u><u>x</u><u>)</u>
- replace x by 2
- do exponent
- distribute the brackets
- do addition and subtraction
g(x)
- replace x by 2
- distribute the bracket
- do subtraction
