Carlie’s Cell Phone Store has a gross income of $1,287,684 and deductions of $598,982. What is the federal corporate income tax?
slava [35]
Carlie's Cell Phone Store owes a total of $144,627 in taxes.

1.) $1,287,684 - $598,982 = $688,702
Due to Tax Cuts and Jobs Act of 2017, corporate tax rate is fixed at 21%. Hence:

2.) $688,702 * .21 = $144,627.42 or $144,627

A table has an area of 12 ft squared and a perimeter of 16 ft. What are the dimensions of the table?
Likurg_2 [28]
P=2x+2y, y=(p-2x)/2

a=xy, using y found above in this equation gives you:

a=(px-2x^2)/2  we are told a=12 and p=16 so

12=(16x-2x^2)/2

24=16x-2x^2

2x^2-16x+24=0

2x^2-12x-4x+24=0

2x(x-6)-4(x-6)=0

(2x-4)(x-6)=0

2(x-2)(x-6)=0

So the table is 2 ft by 6 ft.

12 has a variable after it, so 12 is a coefficient.

Which is a qualitative graph? On a coordinate plane, a line with positive slope goes through points (negative 1, 0) and (0, 3).
guapka [62]

Answer:

(-1,0), (0,3) and (2,2.25)

Step-by-step explanation:

The qualitative graph is as follows:

A(-1,0) ------> B(0,3) ------> C(2,2.25)

Hence, slope = (2.25 - 0)/(2 - (-1)) = 2.25/3

∴ slope = 0.75
