34kurt3 years ago

3 0

Answer: $x(x-2)$

Step-by-step explanation:

We have the following expression:

$-x^2 + 2x$

Which can also be written as:

$2x-x^2$

Here, the common factor is $x$ . Hence, if we apply this common factor we will have:

$2x-x^2=x(2-x)$

Then, the factored form is: $x(2-x)$

Answer:

$y=4(3)^x$

Step-by-step explanation:

From the table given in the question,

x y Difference Ratio

1 12 - -

2 36 36-12 = 24 $\frac{36}{12}=3$

3 108 108-36 = 72 $\frac{108}{36}=3$

4 324 324-108 = 216 $\frac{324}{108}=3$

5 972 972-324 = 648 $\frac{648}{216}=3$

There is a common ratio of 3 in each successive term.

Therefore, data given in the table will represent an exponential function.

$y=a(b)^x$

For a point $(1, 12),$

$12=a(b)^1$

$ab=12$ ------(1)

For another point of the table $(2,36)$ ,

$36=a(b)^2$

$ab^2=36$ --------(2)

Equation (2) divided by equation (1)

$\frac{ab^2}{ab}=\frac{36}{12}$

$b=3$

From equation (1),

$3a=12$

$a=4$

Therefore, exponential function will be,

$y=4(3)^x$

Schach [20]

Answer:

181 $\frac{1}{2}$

Step-by-step explanation:

To find how many hours they work per month multiply the amount of hours they work each day by the amount of days they work in a month:

$22 *8\frac{1}{4} = 181\frac{1}{2}$

They work $181\frac{1}{2}$ hours per month.
