Jeffrey loves living in the house where he grew up, but the house is starting to show its age. His latest project is to replace his kitchen countertops with granite, which he plans to pick up from the hardware store tomorrow. The granite weighs 16 pounds per square foot, and his pickup truck bed can safely hold half a ton of weight. If he also plans to pick up a 120-pound kitchen sink in the same trip, how many square feet of granite will his truck be able to carry?

Jeffrey's pickup truck will be able to carry 55 square feet of granite.

Step-by-step explanation:

There are 2000 pounds in 1 Ton

Jeffrey's pickup truck bed can safely hold half a ton of weight.

So that means his pickup truck can hold

2000/2 = 1000 pounds

He also plans to pick up a 120-pound kitchen sink in the same trip.

So the remaining weight limit is

1000 - 120 = 880 pounds

Since the granite weighs 16 pounds per square foot

880/16 = 55 sq ft.

Therefore, Jeffrey's pickup truck will be able to carry 55 square feet of granite.

hello,

as we don't know if g(x) is continue,

answer b

f(x)=2x²-8x+1=2(x²-4x+4)+1-8=2(x-2)²-7

vertex is (2,-7) ( a minimum since coefficient of x² is > 0)
