<h3>Answer: 10</h3>

Explanation:

"percent" means "per one hundred". Think "cent" as in "100 cents in a dollar". That's one way to remember.

So when we say something like 2%, we mean 2 out of 100 leading to the fraction 2/100 = 0.02

The same applies for 4.8% turning into 4.8/100 = 0.048

A quick shortcut without the use of a calculator has us move the decimal point 2 spots to the left to go from 4.8% to 0.048

-------------

After converting 4.8% to 0.048, we then multiply this by 200

200*(0.048) = 9.6

this value rounds to 10 which is the answer

45% of the 647 students at Royal Oak High attended the football game. How many students did not attend?

Lostsunrise [7]

First multiply
.45*647= 291.15
291.15 is the number of people that attended
subtract 291.15 from 647 and you get 355.85 wait.. but that's not possible so just round it so the answer to your question is 355 people did not attened

Does the table represent a linear function? Explain why or why not

OlgaM077 [116]

The table doesn't represent linear function

Step-by-step explanation:

We need to identify if the table represent a linear function or not.

<u>Linear Function </u>

A linear function is defined as a straight line with an x and y intercept and the same slope through the whole line.

Finding the slope of elements in the table:

x y

0 0

1 1

2 8

3 27

Slope= y/x

Slope = 0/0=0

slope = 1/1 = 1

slope = 8/2 = 2

slope = 27/3 = 9

The function represented is: y=x^3

Since the slope of points x and y in the table is not same, and its graph is not linear.

So, the table doesn't represent linear function

Write the expression as a single natural logarithm.3In3+3Inc

k0ka [10]

Answer:

$ln(27c^3)$

Step-by-step explanation:

Given: $3ln(3)+3ln(c)$

If there is a coefficient in front of a $log$ or $ln$ , that means it becomes an exponent.

$ln(3^3)+ln(c^3)$

Simplify the exponent.

$ln(27)+ln(c^3)$

When there is addition between two logarithms or natural logarithms, it means they multiply together.

$ln(27c^3)$

What is the sum of the roots of the quadratic equation x²+6x-14=0?

aivan3 [116]

Answer:

<h3>Sum of Roots =<u> (-8)</u><u> </u><u> </u></h3><h3>Product of Roots = <u> </u><u> </u><u>(-84)</u><u> </u><u> </u></h3>

Step-by-step explanation:

${x}^{2} + 6x - 14 = 0$

Roots :- 6 and -14

Sum of the roots :

[6 + (-14)]

= (-8)//

Product of the roots :

[(6)(-14)]

= (-84)//
