Step-by-step explanation:
f(x) = 5x - 8
g(x) = 9 - 6x²
= (fog)(-3)
= f( g(3) )
= 5x - 8
= 5(9 - 6x²) - 8
= 5(9 - 6(-3)² ) - 8
= 5(9 - 54) - 8
= 5(-45) - 8
= -225 - 8
= -233
(fog)(-3) = -233
For the first one you will do 9 divided by 3 to the power of 2 For the second one it will be 27 divided by 3to the power of 3 the last one will be 81 divided by 3 to the power of 4
Answer:
2.50
Step-by-step explanation:
ok, so we start out with a 6 cup bag of cheese. But then she uses 2.25 cups to make lasgna, and 1.25 cups to make pizza. we need to see how much cheese is left after she used the cups. First lets add the 2 cups: 1.25 + 2.25. Lets first add 1 + 2 = 3, then .25 + .25 = .50. Lets now add 3, and .50, and that gives us 3.50. Now to see how much cheese is left, we must subtract 6 minus 3.50, which gives us a total of 2.50. I hope that helped!
Answer:
2*12 = 24
12*2 = 24
24/2 = 12
24/12 = 2
Step-by-step explanation:
You have two groups called feet. In each group (foot), you have 12 inches. You would use the fact family 2, 12, and 24 to find the number of inches in 2 feet because you have 2 feet, each foot contains 12 inches, and 2*12 is 24.
Answer:
36 1/4 in³
Step-by-step explanation:
v = 3 5/8 * 2 1/2 * 4
Convert to improper fractions
v = 29/8 * 5/2 * 4/1
Cancel
v = 29/2 * 5/2 * 1/1
Multiply
v = 145/4
Reduce
v = 36 1/4 in³
