<h3>The needed equation representing the profit y is represented in the option B.</h3><h3>B. y = -x² + 50 x - 300 </h3>

Step-by-step explanation:

Here, the given options are incomplete.

A. y² = 4 x² - 100

B. y = -x² + 50 x - 300

C. x = -y² + 60 y - 400

D. x ² = - 6 y² + 200

The number of items sold by the company = x

The profit ( in thousands) is represented as = y

Now, here as we are looking for the equation representing profit (y)

So, we can disregard the equations which has terms (x) and ( x²) in left.

⇒The equations in the options C and D are eliminated.

Similarly, again we are looking for the equation for Profit , not (profit)².

So,we can disregard the equation which has terms (y²) in left side.

⇒The equation in the options A is eliminated.

Hence, the needed equation representing the profit y is represented in the option B.

B. y = -x² + 50 x - 300

Answer:

m = -4

*Pick the option-> (m) is negative

Step-by-step explanation:

$\frac{3}{4}m + 5 = 2$

Solve this equation with inverse operations;

$\frac{3}{4}m + 5 = 2\\-5\\\\\frac{3}{4}m = -3\\*\frac{4}{3}\\\\m = -4$

Urgent! <br> Find the area created by the overlapping circles given the following information.

Stels [109]

Answer:

209.55in²

Step-by-step explanation:

Find area of sector CADE

Radius =22 in

Angle=90°

Formula to apply is ;

Ф/360 × π × r² where

Ф=angle of sector, π=3.142 and r =radius of circle

$A=\frac{90}{360} *3.142*22*22=380.182in^2$

Find area of triangle CAD where base length is 22 inches and height is 22 inches

Area of triangle formula is;

1/2×b×h where b is base and h is height

$A=\frac{1}{2} *22*22=242in^2$

Find area remaining

380.182-242=138.182in²

Find the area of sector CBDF

Radius=28in

Angle=60°

Formula to apply is ;

Ф/360 × π × r² where

Ф=angle of sector, π=3.142 and r =radius of circle

$A=\frac{60}{360} *3.142*28*28=410.55in^2$

Area of triangle BDC

The formula to apply is

1/2×a×a×sinФ where a=28 inches and Ф=60°

$\frac{1}{2} *28*28*sin60=339.48in^2$

Remaining area

410.55-339.48=71.075in²

Area created by overlapping circles

138.182+71.075=209.26in²
