Step-by-step explanation:

We know the other side of the rectangle is 18.

So 18=10+2x

subtract 10

8=2x

divide by 2

x=4

What are the domain and range of f (x) = (one-fifth) Superscript x?

natka813 [3]

Answer:

The domain of the function is all real numbers $(-\infty,\infty)$ and the range is all positive real numbers $(0,\infty)$

Step-by-step explanation:

We have the following function $f(x)=(\frac{1}{5} )^x$ and we want to find the domain and the range.

The function we have is an example of an exponential function $f(x)=b^x$ with b > 0 and b ≠ 1. This types of functions in general have the following properties:

It is always greater than 0, and never crosses the x-axis
Its domain is the set of real numbers
Its Range is the Positive Real Numbers $(0,\infty)$

The domain of a function is the specific set of values that the independent variable in a function can take on.

When determining domain it is more convenient to determine where the function would not exist.

This function has no undefined points nor domain constraints. Therefore the domain is $(-\infty,\infty)$ .

The range is the resulting values that the dependent variable can have as x varies throughout the domain. Therefore the range is $(0,\infty)$ .

We can check our results with the graph of the function.

At a particular restaurant, each onion ring has 70 calories and each slider has 200 calories. A combination meal with onion ring

crimeas [40]

Answer:

3x + 6y

x = sliders

y = onion rings

Step-by-step explanation:

2:1 ratio of onion rings to sliders, add them 200+70+70 = 340,

then 1020/340 = 3, then input into an equation remembering the ratio of onion rings to sliders

The table represents an exponential function.

Minchanka [31]

we know that

The multiplicative rate of change of the exponential function between two points is equal to

$[f(b) / f(a) ] / (b-a)$

Let

$A(1,6)\\B(2,4)$

we have that

$f(a)=6\\f(b)=4\\a=1\\b=2$

substitute in the formula

$[4 / 6 ] / (2-1)=4/6=2/3$

Let

$A(3,8/3)\\B(4,16/9)$

we have that

$f(a)=8/3\\f(b)=16/9\\a=3\\b=4$

substitute in the formula

$[(16/9) / (8/3) ] / (4-3)=48/72=2/3$

therefore

<u>the answer is the option</u>

B.) 2/3
