Answer:
Step-by-step explanation:
If 3⁄4 gallons of water come out of a hose in 15 minutes, to calculate the rate of water that comes out in an hour (60 minutes), we will use the expression;
3/4 gallons = 15 minutes
x gallons = 60minutes
cross multiply
15x = 3/4 * 60
15x = 180/4
15x = 45
x = 45/15
x = 3/1
x = 3:1
Hence the water rate in gallons per hour is 3 gallons per hour
Answer:
79665
Step-by-step explanation:
26555 + 26555 is 53110 then add 26555 again at it equals 79665
f(x) = x² + 7x + 10
f(0) = (0)² + 7(0) + 10 = 10 ----> (0, 10)
f(2) = (2)² + 7(2) + 10 = 28 -----> (2, 28)
rate of change is slope:
=
= 9
