The vertex of a parabola is the maximum or minimum value, and it’s represented by (x,y). The axis of symmetry is the vertical line that runs through the x axis, and also runs through the vertex. This means that the x value in the vertex (x,y) can represent the axis of symmetry.

find the area of the window 24inch by 30inch and convert in to square feet, round the anwser to the second decimal place
Nezavi [6.7K]

Answer:

5 sq. ft.

Step-by-step explanation:

To find the area of a rectangle, use this formula: A = lw.

Because you know two side lengths of the window, you can just plug in the numbers to the formula.

But not yet! You need to convert the given lengths into feet first.

You know that there are 12 inches in 1 foot.

So:

24 inches ÷ 12 inches/foot = 2 feet

30 inches ÷ 12 inches/foot = 2.5 feet

Alright, now you can plug in these lengths into the formula.

A = (2) (2.5) = 5 sq. ft.

The question asks you to round, but there is nothing to round, so you are done here.

Allison works for a computer software company. She earns \$225$225dollar sign, 225 per week plus \$25$25dollar sign, 25 for each
postnew [5]

Answer:

7 software packages

Step-by-step explanation:

Given,

Signing amount = $ 225,

Additional amount for each software package = $ 25

Thus, the total amount for x software packages = signing amount + additional amount for x packages

= 225 + 25x

If total amount ≥ $ 400

225 + 25x ≥ 400

25x ≥ 400 - 225

25x ≥ 175

\implies x \geq \frac{175}{25}=7

Hence, the minimum number of software packages that she must sell would be 7.

A can of soda can have a minimum of 35 milligrams of sodium and a maximum of 45 milligrams of sodium. Write an absolute value in
inessss [21]

An absolute value inequality that represents the acceptable amounts of sodium is; 35 ≤ A ≤ 45

<h3>What is the Absolute Value Inequality?</h3>

We are told that a can of soda can have a minimum of 35 milligrams of sodium and a maximum of 45 milligrams of sodium.

Now, an absolute value inequality that represents this expression would be written as;

35 ≤ A ≤ 45

Thus, we conclude that an absolute value inequality that represents the acceptable amounts of sodium is; 35 ≤ A ≤ 45
