Select all of the following functions that are quadratic.

y = 2x2

3 = 2x2 – 8

y = –2 + 2x – 8

y + 3x = 2x2 – 8

y +3x2 = 2x + 3x2 – 8

Answers

Answer 1

Answer:

y = 2x2

y + 3x = 2x2 – 8

Step-by-step explanation:

Answer 2

The equations that are quadratic in nature are -

y = 2x²2x² - 8 - 3 = 0y = 2x² - 3x - 8

What is a quadratic equation?

A quadratic equation is a equation that is of the form -

y = f{x} = ax² + bx + c.

Given are the set of equations.

A quadratic equation is a equation of degree 2. The equation with degree 2 are -

y = 2x²2x² - 8 - 3 = 0y = 2x² - 3x - 8

Therefore, the equations that are quadratic in nature are -

y = 2x²2x² - 8 - 3 = 0y = 2x² - 3x - 8

the volume of a bucket of water is 864 cubic inches. how many buckets are needed to fill a 7 cubic foot tank?

Answers

Answer:

We have the relation:

1ft = 12 inches.

Then, if we cube both sides, we have:

(1ft)^3 = (12 in)^3

1ft^3 = 288 in^3.

Now we know that:

The bucket is 864 in^3

The tank is 7 ft^3.

knowing that 1 ft^3 = 288in^3

Then 7 ft^3 is seven times that:

7ft^3 = 7*(1ft^3) = 7*(288in^3) = 2016 in^3

Now the number of buckets needed to completely fill the tank is:

N = (2016 in^3)/(864in^3) = 2.33

So you need 2.33 buckets, or we can round it up to 3 buckets, where the third bucket will have some water inside it when the tank is completely filled.

stadium already has 250 people in it at noon.If 35 people per minute enter the stadium,how many are in the stadium at 1:30 p.m. when a concert is supposed to begin?

Answers

Answer:

3,400 people

Step-by-step explanation:

First, find how many minutes are between noon and 1:30 pm

This is an hour and 30 minutes, so it will be 90 minutes

Then, multiply 90 by 35, since 35 people enter per minute

90(35)

= 3150

Then, add the 250 people that were already in it

3150 + 250

= 3400

So, there will be 3,400 people in the stadium

Answer:

3400

Find the cost price of each printer.​

Answers

Answer:

$200.

Step-by-step explanation:

Each computer costed $1,250.

Mr. Chan bought 20 computers.

20 × $1,250 = $25,000

$25,000 out of the $30,000 was spent on computers. That leaves $5,000. Which means $5,000 was spent on the printers.

$5,000 ÷ 25 = $200

(25 = amount of printers.)

So each printer was $200.
