Answer 1

Answer:

Answer:

Option 4 - domain: {x | x is a real number}; range: {y | y > –9}; asymptote: y = –9

Step-by-step explanation:

Given : $h(x)=(0.5)^x-9$

To find : What are the domain, range, and asymptote of h(x) ?

Solution :

Domain of the function is where the function is defined

The given function $h(x)=(0.5)^x-9$ is an exponential function

So, the domain of the function is,

$D=(-\infty,\infty) , x|x\in \mathbb{R}$

i.e, The set of all real numbers.

Range is the set of value that corresponds to the domain.

Let $y=(0.5)^x-9$

If $x\rightarrow \infty , y\rightarrow -9$

If $x\rightarrow -\infty , y\rightarrow \infty$

So, The range of the function is

$R=(-9,\infty) , y|y>-9$

The asymptote of the function,

Exponential functions have a horizontal asymptote.

The equation of the horizontal asymptote is when

$x\rightarrow \infty$

$y=(0.5)^\infty-9$

$y=-9$

Therefore, Option 4 is correct.

Domain: {x | x is a real number}; range: {y | y > –9}; asymptote: y = –9

Answer 2

Answer: Among the choices provided above the domain, range, and asymptote of h(x) = (0.5)x – 9 is the below:

domain: {x | x is a real number}; range: {y | y > –9}; asymptote: y = –9

Which ratio forms a proportion with 16/20

Answers

Answer:

4/5 forms a proportion with 16/20.

Step-by-step explanation:

We are given an rational number as 16/20.

we have to find another rational number which is equivalent to it.

as both 16 and 20 are multiple of 4 we could also represent the ratio 16/20 as:

$(16)/(20)=(4 * 4)/(4*5)$

we cancel 4 on both the numerator and denominator to get $(4)/(5)$ .

Hence, the ratio $(4)/(5)$ is proportion with $(16)/(20)$ .

4/5 is equivalent to the fraction 16/20

What is the chance of rolling a 4 with a single dice 3 times

Answers

The chance of rolling a 4 is 1/6 .

If you already have one, then the chance of rolling another one is 1/6 .

If you already have two, then the chance of rolling another one is 1/6 .

So, starting from the beginning, the chance of rolling three of them
IN THREE TOSSES is

(1/6) x (1/6) x (1/6) = 1/216 = about 0.46 % .

The question actually just says "the chance of rolling a 4 three times".
If you just look at it that way, the chance could be 100% ... it doesn't
say anything about how many tosses you get, and you're just going to
keep rolling that durn cube until you get three 4's.

3/18. This is because you roll a 4 3 times, and I'm assuming it's a standard 6 sided die (singular for dice). 3 x 6 = 18 and 3 x 1 = 3.

0.7(3s+4)−1.1s=7.9 I need a answer

Answers

First, expand the bracket

2.1s + 2.8 - 1.1s = 7.9

Next, collect like terms

s + 2.8 = 7.9

Lastly subtract 2.8 from 7.9 to get your answer.

s = 5.1

(Hope this helps! ^^)

Answer:

$\boxed {s = 5.1}$

Step-by-step explanation:

Solve for the value of $s$ :

$0.7(3s + 4) - 1.1s = 7.9$

-Use Distributive Property:

$0.7(3s + 4) - 1.1s = 7.9$

$2.1s + 2.8 - 1.1s = 7.9$

-Combine like terms:

$2.1s + 2.8 - 1.1s = 7.9$

$s + 2.8 = 7.9$

-Subtract $2.8$ to both sides:

$s + 2.8 - 2.8 = 7.9 - 2.8$

$\boxed {s = 5.1}$

So, the value of $x$ is $5.1$ .

Definition of mean, median, mode & range?

Answers

Mean: Add all the numbers divide by the amount of values
Median: the middle number in a set of data
Mode: the most common number that appears in a set of data
Range: biggest number take away the smallest number

Mode: number that appears the most
Mean: all the numbers added together and then that number divided by the amount of numbers u counted to get the solution for the addition.
Range: subtract the highest number from the smallest number
Median: put the numbers from least value to the top value and the Median will be in the middle
