The figure shows the graphs of the cost and revenue functions for a company that manufactures and sells small radios. More than

Lyrx [107]

ANSWER

The company must produce and sell more than 700 radios to have a profit.

EXPLANATION

The revenue function is

$R(x)=40x$
and the cost function is

$C(x)=5,600+32x$

The company will break even when total revenue is equal to the total cost.

This implies that,

$40x =5,600+32x$

We group similar terms to get,

$40x - 32x = 5600$

This simplifies to,

$8x = 5600$

Divide both sides by 8 to get,

$x = \frac{5600}{8}$

$x = 700$

The company breaks even by producing and selling 700 radios.

The company must produce and sell more than 700 radios to have a profit.

Triangle ABC is shown below.

Andrew [12]

Answer:

C.) 14

Step-by-step explanation:

Look at the triangle: angles b and c have the same arch, so they are congruent.

In a triangle, if two angles are congruent, then the triangle is isosceles, having two equal sides.

The sides opposite the congruent angles are congruent:

∠B → opposite side → AC

∠C → opposite side → AB

The sides AB and AC are equal. Make an equation:

$AB=AC\\\\2x=3x-7$

Simplify the equation, solving for x. Add 7 to both sides:

$2x+7=3x-7+7\\\\2x+7=3x$

Subtract 2x from both sides:

$2x-2x+7=3x-2x\\\\7=x$

The value of x is 7. Insert the value of x into the given length of AC:

$AC=3(7)-7$

Simplify multiplication:

$AC=21-7$

Subtract:

$AC=14$

Therefore, the length of the line segment AC is 14.

What is the coefficient in the mathematical expression?

barxatty [35]

Using it's concept, it is found that the coefficient of the mathematical expression 7m² + 2(19) is of 7.

<h3>What is the leading coefficient of a polynomial?</h3>

The leading coefficient of a polynomial is the <u>term that multiplies the highest exponent</u>.

In this problem, the expression is given by:

7m² + 19.

The highest exponent is of 2, in m², hence the leading coefficient is of 7.
