How to evaluate the piece-wise function?The function is given as:
[tex]f(x) = \left[\begin{array}{cc}x-3&x\le-4\\3x-2&-4 < x\le 2\\-2x+4&x > 2\end{array}\right][/tex]
The above definition means that:
All x values less than or equal to -4 would be evaluated using f(x) = x - 3All x values greater than -4 but less than or equal to 2 would be evaluated using f(x) = 3x - 2All x values greater than 2 would be evaluated using f(x) = -2x + 4Using the above highligts, we have:
f(-4) = -4 - 3 = -7
f(-2) = 3(-2) - 2 = -8
f(0) = 3(0) - 2 = -2
f(2) = 3(2) - 2 = 4
f(4) = -2 * 4 + 4 = -4
f(8) = -2 * 8 + 4 = -12

You have a bag of marbles. In the bag, there is a red, blue,
white, yellow, orange and black marble. Find the probability
that you choose the red, then the blue marble (you don't
replace the first marble you draw). Express your answer as a
simplified fraction.
Answer:
1/6 probability that you choose red
1/6 probability that you choose blue
Step-by-step explanation:
There are 6 marbles and only one is red, same with blue, so out of six times you pick a marble you will get the blue once and red once.
A square pyramid is shown sitting on its base.
Answer:
312
Step-by-step explanation:
First we find the measure of the basea and that is 144 becuase 12x12
To find one side we do b*h over 2 and that is 7x12/2 which is 42 then we know that there are 4 more of those sides and we get 42*4 168
When we add 144+168 we will get 312

Oh no! He seems to be missing some parts though. He was "robbed" of his
asymptotes.
Luckily, he can remember what they were:
1. This functions vertical asymptote was x=-5.
2. This functions horizontal asymptote was y = 12.
Please recreate this function with those identifying features! Please make sure it
looks like the function in the picture
Let's do
[tex]\\ \rm\dashrightarrow y=\dfrac{3}{x-h}+k[/tex]
Release k for some while
If
we take h=0So
y=3/xSo vertical asymptote is at origin now
It mentioned that it's at x=-5 so we need to change x
put -5 in place of h[tex]\\ \rm\dashrightarrow y=\dfrac{3}{x-(-5)}[/tex]
[tex]\\ \rm\dashrightarrow y=\dfrac{3}{x+5}[/tex]
Vertical asymptote at x=-5Now
for k=0 horizontal asymptote at originBut it's given
y is at 12Same put y=12 in place of k

Volume of a box If a box has a volume of 42 cubic feet, is it possible for you to
fit inside the box? Explain your answer
Answer:
yes ,because the average human hight
cannot exceed 7squared feets
Without knowing the dimensions of the box or the size of the person, we cannot determine whether the person can fit inside the box or not.
What is a box?In mathematics, a box is a three-dimensional shape that has six rectangular faces.
It is also called a rectangular prism.
The faces on opposite sides of a box are congruent and parallel. A box has a height, width, and length, which are usually labeled as h, w, and l.
The volume of a box can be found by multiplying its length, width, and height: V = l × w × h.
We have,
The volume of a box is a measure of the amount of space inside the box, typically measured in cubic units such as cubic feet or cubic meters.
If a box has a volume of 42 cubic feet, it is simply telling us the amount of space inside the box.
Whether a person can fit inside the box or not depends on the size of the box and the size of the person.
Without knowing the dimensions of the box or the size of the person, we cannot determine whether the person can fit inside the box or not.
So,
We need more information to answer this question.
Thus,
Without knowing the dimensions of the box or the size of the person, we cannot determine whether the person can fit inside the box or not.

Consider the information about the number of customers that select various frame
colors at a frame store one day.
• 15 customers select white frames.
• 30 customers select black frames.
• 45 customers select gold frames.
Part A
If there are a total of 2.200 customers that order from the frame store one month, what
is the best approximation for how many customers that month select a black frame?
A. 367 customers
B. 733 customers
C. 1, 100 customers
D. 1. 167 customers
Answer:
B. 733 customers
Step-by-step explanation:
15+30+45=90
since 30 people select a black frame, 1/3 of the customers picked black frames. If this data is consistent through the month (which we have to assume it is) then that means 1/3 of customers select a black frame on average. 1/3 of 2,200 is about 733, so we can assume, using the data given, that about 733 customers selected black frames! :)
