Answer:
x ≠ -3, x ≠ 3
Step-by-step explanation:
As with any rational function, the denominator cannot be zero. Here that means we cannot have x such that ...
x² -9 = 0
(x -3)(x +3) = 0
x = 3 or -3 . . . . . . . values not allowed in the domain

Answer:
Length DE= 2√2
Length EF= 2√2
Step-by-step explanation:
The 45-45-90 rule is very special but this question is really simple. You have all the angles and one side.
STEPS:
1) Take 45 from angle D and use its sine to find side EF
2) sin45= x/4 => 2.82 or 2√2
3) Take either cos45 from angle D or use Pythagoras since we now have enough side lengths to use Pythagoras (faster for me to use cosine).
4) cos45=x/4 => 2.82 or 2√2
Further explanation:
If you don't understand the sine and cosines, here's a word play to help.
S O/H
C A/H
T O/A
S=Sine
C=Cosine
T= Tangent
O= Opposite
H= Hypotenuse
A= Adjacent
If you search a video on this word play it will help more since it is visual.

A bag contains 5 red marbles, 6 blue marbles, 3 green marbles, 4 black marbles, and 2 yellow marbles. A marble will be drawn from the bag and replaced 100 times. What is a reasonable prediction for the number of times a green or black marble will be drawn?
A quick lesson on probability:
The probability of an event is: (the number of ways what you want can happen) / (total number of outcomes possible). For example, in a coin flip, there is 1 way to get heads, and 2 possible outcomes. Thus, the possiblity of flipping a coin and getting heads is:
(1 way to get heads) / (2 possible outcomes) = 1/2
Then, if we were to flip the coin 100 times, we would expect about 1/2 of the times to be heads, so we should expect heads 50 times.
On to the problem.
There are 3 green marbles and 4 black marbles, so there are 7 ways to draw a green or black marble.
Then, there are 5 + 6 + 3 + 4 + 2 = 20 possible outcomes.
Using the formula to find the probability, substitute the values we just found.
(the number of ways what you want can happen) / (total number of outcomes possible) =
(7 ways to draw a green or black marble) / (20 marbles that can be drawn) = 7/20 chance of getting a green or black marble.
Then, because there is a 7/20 chance of getting what we want, and there are 100 draws, we can say that an we should get green or black
7/20 * 100 = 35 times, or D

Answer: The 3rd one.
Step-by-step explanation:
please help i will mark brainliest- Compare the function represented on the graph and the function modeled by y=2/3x
The comparison of the given function and the graph is required.
It is true that y-intercept of both functions is 0.
It is false that the slope of both functions is [tex]\dfrac{3}{2}[/tex]
It is true that the graphs function has a greater rate of change.
It is true that point (0,0) is the point of intersection for both the functions.
Function and graphsTwo points of the graph are (0,0),(-2,-3).
The equation of the line is
[tex]y-0=\dfrac{-3}{-2}(x-0)\\\Rightarrow y=\dfrac{3}{2}x[/tex]
The other equation is [tex]y=\dfrac{2}{3}x[/tex]
Both the lines pass through the origin so the y intercept of both the functions is 0.
Only the slope of the function in the graph is [tex]\dfrac{3}{2}[/tex] the other function has slope [tex]\dfrac{2}{3}[/tex]
Writing the decimal forms of the slopes [tex]\dfrac{3}{2}=1.5[/tex] and [tex]\dfrac{2}{3}=0.67[/tex]
The function in the graph does have a greater rate of change.

Weekly wages at a certain factory are
normally distributed with a mean of
$400 and a standard deviation of $50.
Find the probability that a worker
selected at random makes between
$300 and $350.
Answer:
0.136
Step-by-step explanation:
If you have a calculator with statistical functions, this problem is straightforward.
Use the normcdf function as follows:
normcdf(300,350,400,50) = 0.136
This result is the probability that a worker makes between $300 and $350 per week: 0.136
