<h3>Quadratic functions</h3>

Quadratic functions are functions that has a leading degree of 2.

Given the equation that represents  roller coaster’s height as shown

h = –0.025t^2 + 4t + 50

The coaster will reach the ground when h = 0

Substitute

0 = –0.025t^2 + 4t + 50

Factorize

On factorizing, the time it took the rider to reach the ground level is 171.651seconds

ELEN [110]

Sajia can sell 21 books she can sell if she comes back on sunday and the required inequality is 9 + x \leq 30

<em><u>Solution:</u></em>

Given that Sajia has 30 Books in her library

She sold 9 books at the thrift store on Saturday

To find: We have to write and solve an inequality to determine number of more books she can sell if she comes back on sunday

Let "x" be the number of more books she can sell if she comes back on sunday

<em><u>We can write a inequality as:</u></em>

\text{ books already sold } + \text{ number of books remaining } \leq \text{ total number of books she has }

9 + x \leq 30

Now moving 9 from L.H.S to R.H.S we get,

x \leq 30 - 9

On solving 30 - 9 = 21,

x \leq 21

So Sajia can sell 21 books she can sell if she comes back on sunday

Mark bought 3 bags of pretzels for $2.00 each. He also bought 2 bottles of juice for $1.50 each. Write an expression and find th
Agata [3.3K]

Answer:

Total Cost for Pretzels and juice is $9.

Step-by-step explanation:

Given:

Number of Bags of pretzels =3

Cost for each bag = $2.00

Total Cost of Pretzels is equal to product of Number of Bags of pretzels and Cost for each bag.

Framing in equation form we get;

Total Cost of Pretzels = 3\times 2= \$6

Also Given:

Number of Bottle of Juice = 2

Price of each bottle = $1.5

Total Cost of Juice is equal to product of Number of Bottle of Juice and Price of each bottle.

Framing in equation form we get;

Total Cost of Juice = 2\times 1.5= \$3

Total Cost of Pretzels and juice is equal to sum of Total Cost of Pretzels and Total Cost of Juice.

Total Cost of Pretzels and juice = Total Cost of Pretzels + Total Cost of Juice

Total Cost of Pretzels and juice = $6 + $3 =$9

Hence Total Cost for Pretzels and juice is $9.
