Answer:
f(-3)=9
Step-by-step explanation:
We want to find what f(x), or y is, when x is equal to -3.
f(x)=x^2
We want to find f(-3). Therefore, we can substitute -3 in for x.
f(-3)=(-3)^2
Evaluate the exponent. -3^2 is the same as -3*-3.
f(-3)=-3*-3
f(-3)=9
Answer:
28.4 kg
Step-by-step explanation:
F = ma
F is 25 N and a is 0.88 m/s^2
25 = 0.88m

m = 28.4 kg
Answer:
To find out how much area he will paint, you will find the area of all 6 faces.
Each face is in the shape of a rectangle, so use A = lw as your formula.
Front/Back: 80 x 36 = 2880 square inches
2880 square inches x 2 = 5760 square inches
Right/Left Sides: 80 x 2 = 160 square inches
160 square inches x 2 = 320 square inches
Top/Bottom: 36 x 2 = 72 square inches
72 square inches x 2 = 144 square inches
5760 + 320 + 144 = 6224 square inches.
Cody will paint 6224 square inches.
Hope this helps!
7, because 8/4 = 2 which means that 1 guest = $2. So if we do 14 / 2 to see how many guests that would be, it's 7.
