Answer 1

Answer:

Domain: All real numbers, Range: All real numbers greater or equal to 0.

Step-by-step explanation:

A second order polynomial is a continuous function and therefore, domains is the set of all real numbers. Lastly, the range of the function according to the graph is all values of x greater or equal to 0. The positive leading coefficient of the polynomial indicates the existence of an absolute minimum.

pure antifreeze. The company wants to obtain
320

gallons of a mixture that contains
55

pure antifreeze. How many gallons of water and how many gallons of the premium antifreeze solution must be mixed?

Answers

Answer:

let w = amt of water required

An equation based on the the percent water, an 80% solution is 20% water.

.20(320-w) + w = .50(320)

64 - .2w + w = 160

.8w = 160 - 64

w = 96%2F.8

w = 120 gal of water to produce 320 gal of 50% antifreeze

320 - 120 = 200 gal of 80% solution

Then the equation will be

y = kx

Her k = proportionality constant.

Let the point is (2, 10).

By putting the values of x and y in the equation,

10 = 2×k

Martin made 12 out of 40 shots during the basketball game. What percent of his shots did he make?

Answers

Answer:

30 percent

Step-by-step explanation:

12/40=0.3

0.3=30 percent

Answer:

30%

Step-by-step explanation:

To find a percent, use this equation:

x/100 = n/t

where x is the percent, n is the select number of things, and t is the total number of things

Substitute:

x/100 = n/t

x/100 = number of shots Marin made/number of shots attempted

x/100 = 12/40

Now, we need to cross multiply, or multiply the numerators by the denominators of the other fraction, and vice versa.

Multiply:

x/100 = 12/40

x(40) = 40x

100(12) = 1200

40x = 1200

Now, divide both sides of the equation to find the value of x.

Divide:

40x = 1200

/40 /40

x = 30

Now we have the percent is fraction form: 30/100

To make it a percentage, simply take the numerator and add the % sign.

Therefore, Martin made 30% of his shots.

Find the interest on $4,500 at 5.2% for 2 and a half years. Which of the following equations would be used to solve this problem?
Please help!

A: 4500 = P(0.052)(2.5)

B: I = (4500)(5.2)(2.5)

C: I = (4500)(0.052)(2.5)

D: I = (4500)(0.52)(2.5)

Answers

The answer is C: 1=(4500)(0.052

The equations used to solve this problem is I = (4500)(0.052)(2.5).

The correct option is (C).

What is Interest?

Simple interest is a loan interest payment that borrowers pay to lenders. It is based solely on the principal and does not account for compounding interest. Straightforward interest is not limited to certain loans. It is also the form of interest that banks pay on savings accounts.

Given:

P = $4500

R= 5.2%

Time= 2 and half year

Using the formula of Simple Interest

= P x R x T / 100

= (4500 x 5.2 x 2.5)/ 100

= (4500 x 0.052 x 2.5)

= $585

So, the equation is: : I = (4500)(0.052)(2.5)
