Answer:
f(5) = 2
Step-by-step explanation:
To evaluate f(5), that is when x = 5 in the interval x ≥ 5
then
f(5) = 6x - 28 = 6(5) - 28 = 30 - 28 = 2, so
f(5) = 2
Answer:
24π cubic units
Step-by-step explanation:
Using the formula for the volume of a cylinder, you find it to be ...
V = πr²h
V = π(2²)(6)
V = 24π . . . . cubic units
Answer:
60%
STEP BY STEP EXPLANATION:
Answer:
the 3rd one
Step-by-step explanation:
the answer cannot be negative for absolute values. Unless, there is a negative sign outside the absolute value
Find the difference in gallons and the difference in the weights
46 - 12 = 34 gallons
2399 - 2176 = 223 pounds
so 34 gallons of gas weighs 223 pounds
find weight per pound: 223 pounds / 34 gallons = 6.5588 pounds per gallon
round to 6.6 pounds per gallon
54 gallons - 46 gallons = 8 gallons
8 gallons x 6.6 pounds per gallon = 52.8 pounds, round to 53 pounds
2399 + 53 = 2452 weight of plane with 54 gallons
