Answer:

A=16000  B=16400

Step-by-step explanation:

1.  You multiply 20,000 by .2 or 20%, because you are trying to find a part of the 20,000.

2. You get 4,000 dollars, that is 20% of 20,000. To find the sale price, you take the 20% away from 20,000, which would be 16,000 dollars. That would be your answer for the first part.

3. the sales tax is 2.5% of the sale price. Again, you multiply 16,000 dollars, your sales price, by .025 or 2.5%.

4. you would get 400 dollars. You add the 2.5% or 400 dollars because you have to pay the tax as well as the price. You would get 16,400 dollars.

Which description matches the graph of the inequality y ≥ |x + 2| – 3? a shaded region above a solid boundary line a shaded regi
Alex777 [14]
The given inequality is y ≥ |x + 2| -3.

This inequality may be written two ways:
(a) y ≥ x + 2 - 3
    or
    y ≥ x - 1

(b) y ≥ -x -2 - 3
    or
     y ≥ -x - 5

A graph of the inequality is shown below. The shaded region satisfies the inequality.

Answer: A shaded region above a solid boundary line.

Y=mx+b is used for what math equation
soldier1979 [14.2K]
       y = m x + b is a linear equation. 
      This equation is in the slope - intercept form, where m is the slope and b is y - intercept.
       For example: y = 2 x + 5
       In this equation: m = 2 ( the slope ) and b = 5 ( the line intercepts y-axis at the point ( 0, 5 )  ).

A triangle has two constant sides of length 5 feet and 7 feet. The angle between these two sides is increasing at a rate of 0.9
o-na [289]

Answer:12.74 ft^2/s

Step-by-step explanation:

Given

Two sides of triangle of sides 5 ft and 7 ft

and angle between them is increasing at a rate of 0.9 radians per second

let \thetais the angle between them thus

Area of triangle when two sides and angle between them is given

A=\frac{ab\sin C}{2}

A=\frac{5\times 7\times \sin \theta }{2}

Differentiate w.r.t time

\frac{\mathrm{d} A}{\mathrm{d} t}=\frac{35\cos theta }{2}\times \frac{\mathrm{d} \theta }{\mathrm{d} t}

at \theta =\frac{\pi }{5}

\frac{\mathrm{d} A}{\mathrm{d} t}=\frac{35\times cos(\frac{\pi }{5})}{2}\times 0.9

\frac{\mathrm{d} A}{\mathrm{d} t}=12.74 ft^2/s
