5. Anthony owns a business that sells parts for electronic game systems. The profit for his business can be

Ronch [10]

Solution given:

p(x)=0

-0.2x2 + 10x – 25=0

-0.2(x²-50x+125)=0

x²-2.25.x+25²=25²-125

(x-25)²=500

x-25= $\sqrt{500}$

x-25=±10√5

taking positive

x=22.3606+25

x=47.3606

taking negative

x= -22.3606+25

x=2.639

maximum profit Anthony will receive :47.3606*1000= 47360600(approach)

now

47360 .6 or 2639 parts he would need to sell to receive the maximum profit

What is 7 29/80 in a decimal

Elina [12.6K]

7 29/80 as a decimal is 7.3625. First, turn it into an improper fraction: to work out the numerator, add the current numerator (29) to the 7 whole 80ths represented by the integer of the mixed number. (7 x 80) + 29 = 589. 589/80 cannot be cancelled down. As a decimal it is 7.3625.

Solve the quadratic equation by factoring. 9x^2-16=0

Harman [31]

Answer:

x= +- 4/3

Step-by-step explanation:

(3x+4)(3x-4)=0

make each equation set to 0 and solve

3x+4=0

subtract 4 from both sides

3x=-4

divide both sides by 3

x=-4/3

3x-4=0

add 4 to both sides

3x=4

divide both sides by 3

x=4/3

The graph of a function is shown on the coordinate plane below. Identify the rate of

GalinKa [24]

<h3>Answer: 7/4</h3>

=========================================================

How to get that answer:

The slope is the rate of change for any linear function.

Apply the slope formula for any two points on the diagonal line.

I'll use the points (-4, -3) and (0, 4)

$m = \frac{y_2-y_1}{x_2-x_1}\\\\m = \frac{4-(-3)}{0-(-4)}\\\\m = \frac{4+3}{0+4}\\\\m = \frac{7}{4}\\\\$

The slope is m = 7/4

This indicates that each time we go up 7 (rise), we also go to the right 4 units (run)

slope = rise/run = 7/4

rise = 7, run = 4

The fraction 7/4 converts to the decimal form 1.75
