Answer:
f(3) = 9
Step-by-step explanation:
Wherever you see an x on the right, put a 3 in for that x
f(x) = 2x^2 + x - 12
f(3) = 2*(3)^2 + 3 - 12
f(3) = 2*9 + 3 - 12
f(3) = 18 + 3 - 12
f(3) = 9
10 days - 5 days = 5 days.
6 gliders - 3 gliders = 3 gliders.
They make 3 gliders in 5 days: 3/5 = 0.6 gliders per day.
y = 0.6x
The answer is A.
Answer:
64
Step-by-step explanation:
For this, you multiply the 12 two point shots she made to see how many points she earned
12 x 2 = 24
now you will subtract the 24 from 27 to find out how many points are left
27 - 24 = 3
this means she made 12 two point shots (worth 24 points) and 1 three point shot (worth 3 points) to total up as her 27 points:)
Answer:
3280 square inches
Step-by-step explanation:
The surface area of square pyramid = 4* the area of the triangular side + the area of the square base.
TRIANGULAR SIDE
The pyramid has an isosceles triangular side of size, a=40 inches, b= 29 inches, c = 29 inches.
Surface area = sqrt{ s(s-a)(s-b)(s-c) }
Where s= (a+b+c)/2
S= (40+29+29)/2 = 49
Surface area = sqrt{ 49(49-40)(49-29)(49-29)}
Surface area = 420 square inches
SQUARE BASE
Area of a square = a²
Area = 40² = 1600 square inches
Surface area of the pyramid = 4*420 + 1600 = 1680 + 1600
Surface area = 3280 square inches.
