The area, A, in square feet, of a rectangular storage bin in a warehouse is given by the function A(x) = x2 - 6x, where x is the width, in feet, of the storage bin. Part A: Based upon this function, which statement would be true? Show your work or explain how you found the solution.

The x-intercepts of the function are 3 and -9, which are a lower bound and an upper bound for the possible values of the length of the storage bin.

The x-intercepts of the function are 3 and -9, which are a lower bound and an upper bound for the possible values of the width of the storage bin.

The x-intercepts of the function are 0 and 6, which are a lower bound and an upper bound for the possible values of the length of the storage bin.

The x-intercepts of the function are 0 and 6, which are a lower bound and an upper bound for the possible values of the width of the storage bin.

The x-intercepts of the function are 0 and 6, which are a lower bound and an upper bound for the possible values of the width of the storage bin.

Step-by-step explanation:

Given

Required

Which is true about the x intercept

To do this, we make A(x) = 0.

Substitute 0 for A(x) in

Rewrite as:

Factorize:

Split:

Option D is correct

Cost of 7 gallons=$24.50

Cost of 1 gallon=24.50/7=3.5

Cost of 15 gallons=15*3.5=52.5

Cost of 15 gallons will be $52.5

For 1 flavor there are 9 topping

Therefore, for 5 different flavors there will be 5*9 choices

No of choices= 5*9

=45 

The answer is in the image 

The total nom of  code that can be used is equal to 5+3 = 8

The solution is in the following image

y=2x+15

where y=Value of coin

x=Age in years

Value of coin after 19 years=2*19+15

=$53

Therefore, Value after 19 years=$53

Speed=Distance/time

Here,

distance=15m

time=1sec

speed=15/1=15m/sec

Distance=Speed*time

time=15min=15*60sec=900sec

Distance travelled in 15 min=15*900=13,500m

=13500/1000 km=13.5Km

The wood before starting =12 feet

Left wood=6 feet

Wood used till now=12-6=6 feet

Picture frame built till now= 6/(3/4)

=8 pieces

Therefore, till now 8 pieces have been made.
