(f+g)(x) is 3x^2 + 3x/2 - 9
(f+g)(x)=f(x)+g(x)=x/2-3+3x^2+x-6= 3x^2 + 3x/2- 9
Answer:
20%
Step-by-step explanation:
Divide 16 by 80 and you get 0.2 as an answer and to get a percent you move the decimal 2 places to the right to fet 20%
Answer:

Step-by-step explanation:
-In a right triangle, the Sine of the base acute angle is usually given as:

-In ΔVWX,, VX is the opposite and WV the hypotenuse.
-Therefore, sine of ∠Wis calculated as;

Hence, sine of ∠W is given represented by the ratio 
Answer:
Below
Step-by-step explanation:
The corners are the vertices of the rectangle
So to Kick the ball from the corner to the opposite one the player must kick far enough to cross all the width.
The width is 54 m
Then the distance needed is 54 m at least if the ball goes straight.
Answer:
{-3, 29, 21, 33}
Step-by-step explanation:
Substitute the x values (domain) to find y, do this for all x's-
f(x) = 6(-2) + 9 = -3
f(x) = 6(0) + 9 = 9
f(x) = 6(2) + 9 = 21
f(x) = 6(4) + 9 = 33
Range-
Take the y values and arrange it from least to greatest <em>(this matters and your teacher may most likely count it wrong if you do not put it in increasing order)</em>
{-3, 29, 21, 33}
