The production cost, represented by y, of smart phone devices are equal to the product of computing components (a) and the squar

Marta_Voda [28]

The production cost is an illustration of a quadratic function

<h3>How to determine the equation</h3>

We have the following parameters:

Computing components (a)
Number of devices (x),
Labor (b)
Savings on reusable material (c)

Using the instructions in the question, the equation of the production cost would be:

$y =ax^2 + bx -c$

Hence, the production cost is $y =ax^2 + bx -c$

<h3>Change the subject of the equation</h3>

In (a), we have:

$y =ax^2 + bx -c$

Subtract bx - c from both sides

$y - bx + c = ax^2$

Divide through by x^2

$a = \frac{y - bx + c}{x^2}$

Hence, the equation that represents the computing component is $a = \frac{y - bx + c}{x^2}$

Erika calculated that she would spend $115 on school supplies this year. She actually spent $82.50 on school supplies. What is E

DerKrebs [107]

The equation to find percent error is:
percent error=(experimental-theoretical)/theoretical *100
So, (115-82.5)/82.5=0.393939*100
39.3939%, or 39.94%

Hope this helps!!

A: What are the solutions to the quadratic equation x^2+9=0?

Nataliya [291]

Answer:

Part A)

x=-3i

x=3i

Part B)

(x+3i)(x-3i)

Step-by-step explanation:

Given:

Part A)

x^2+9=0

x^2=-9

x= √-9

x=√-1 *√9

x=± i *3

x=±3i

Part B)

x^2+9=0

x^2 - (-9)=0

x2-(3i)^2=0

(x-3i)(x+3i)=0 !
