The functions r and s are defined as follows. r(x)=2x-2 s(x)=-x^2 find the value of s(r(-3)) (please help!)

swat32

Solving equation s(r(x)) for x= -3, you find as result s(r(-3))=-64

<h3>Solving Equations</h3>

The equations can be solved when you replace the variable x for a given value or find the zero of functions.

The question gives:

r(x)=2x-2

s(x)=-x²

First, you will find r(-3). For this, in the equation r(x)=2x-2, you should replace x for -3. Then,

r(x)=2*(-3)-2

r(x)=-6-2= -8

Like r(-3)= -8, you should replace x, in s(x), for -8.

s(x)=-(-8)²

s(x)=-64

Hence, s(r(-3)=-64.

Identify the parameters in the following situation. When Jackie is camping, she sees 6 shooting stars every hour, on average. Wh

andrey2020 [161]

Answer:

The probability that she sees exactly 4 shooting stars in the next hour is 0.13

Step-by-step explanation:

An assumption is made that she see the shooting stars of 6 every hour based on a poisson distribution.

$P(X = x) = \frac{e^{-m} m^{x} }{x!}$

where m is the average per hour = 6

$P(X = x) = \frac{e^{-m} m^{x} }{x!}\\P(X = 4) = \frac{e^{-6} 6^{4} }{4!}\\P(X = 4) = \frac{0.002478752 * 1296 }{4!}\\P(X = 4) = \frac{3.212462592}{24}\\P(X = 4) = 0.133852618\\P(X = 4) = 0.13$

What should larmont do to write a correct point slope equation for this line? <br> (-8,5) and (-5,7)

Ronch [10]

ANSWER

Therefore the correct answer is B

<u>EXPLANATION</u>

The equation in the point slope form of a straight line is given by the formula;

$y-y_1=m(x-x_1)$ , where $m$ is the slope and the point $(x_1,y_1)$ is any point on the line.

Since two points on the line are given, Lamont must find the slope using the points $(-8,5)$ and $(-5,7)$ as follows;

$m=\frac{7-5}{-5--8} =\frac{7-5}{-5+8} =\frac{2}{3}$ .

He can now choose one of the points as $(x_1,y_1)$ .

If he uses $(-8,5)$ , the he obtains,

$y-5=\frac{2}{3}(x--8)$

Which gives $y-5=\frac{2}{3}(x+8)$ as the equation of the line.

Therefore the correct answer is B
