Answer:

Mr. Mole is descending by 2.4 meters per minute

Step-by-step explanation:

Let

x ----> the time in minutes

y ---> the distance in meters

we know that

In this problem the rate of change or slope is the same that the speed

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

take two points from the table

(5,-18) and (8,-25.2)

substitute the values in the formula

$m=\frac{-25.2+18}{8-5}$

$m=-2.4\ meters\ per\ minute$ ---> is negative because is descending

Write the equation of the line passing through points (2,-2) and (1,0) in the slope intercept form

Zinaida [17]

Answer:

y=-2x+2

Step-by-step explanation:

Just follow the slope-intercept form formula-

Formula: y= mx+b

Key:

y = y-coordinate

m = slope

x = x-coordinate

b = y-intercept

A cheetah ran 275 feet in 3.23 seconds. How fast did the cheetah run in miles per hour? Round your answer to the nearest whole m

yawa3891 [41]

First we convert feet into meters, since 1 feet is 0.3048 m: 275 feet * 0.3048 = 83.82m.

Then we do: 83.82m / 3.23s = <span>25.9504644 m/s.

Then we convert that into miles per hour by </span>2.23694, so we do:

25.9504644 * 2.23694 = <span>58.0496318.

Then we round it to 58 mph.

So the answer is: The cheetah was running at 58 mph.

Hope this helped! c:</span>

1. Determine whether the given procedure results in a binomial distribution. If not, state the reason why.

Anna11 [10]

Answer:

1.D) Procedure results in a binomial distribution.

2. B) Procedure results in a binomial distribution.

Step-by-step explanation:

The binomial distributions has following properties.

There is always one of the two outcomes success or failure possible.

The probability of p remains constant for all trials.

The successive trials are all independent.

The experiment is repeated for a fixed number of times.

If the experiment has the above properties it has binomial probability distribution.

In the given question both experiments have the above mentioned properties.

Both procedure result in binomial distribution.

Pleas help me find the composition of goh and it’s domain

Ksivusya [100]

Solution:

The function is given below as

$\begin{gathered} g(x)=\frac{x+4}{x-1} \\ h(x)=2x-1 \end{gathered}$

To figure out

$(goh)(x)$

To do this , we will substitute x= 2x-1 in g(x)

$\begin{gathered} g(x)=\frac{x+4}{x-1} \\ g(h)(x)=\frac{2x-1+4}{2x-1-1} \\ g(h)(x)=\frac{2x+3}{2x-2} \end{gathered}$

Hence,

The composte function will be

$(goh)(x)=\frac{2x+3}{2x-2}$

Step 2:

To figure out the domain,

In mathematics, the domain of a function is the set of inputs accepted by the function.

Hence,

The domain of the function is

$\begin{bmatrix}\mathrm{Solution:}\:&\:x1\:\\ \:\mathrm{Interval\:Notation:}&\:\left(-\infty \:,\:1\right)\cup \left(1,\:\infty \:\right)\end{bmatrix}$
