Answer:
Solution given:
for second
we have
f(x)=x²-9x-36
let
y=x²-9x-36
when
x=0
y=-36
when
y=0
0=x²-9x-36
x²-12x+3x-36=0
x(x-12)+3(x-12)=0
(x-12)(x+3)=0
either
x=12
x=-3
So,
x and y intercepts are (-3,0)(12,0) and 0,-36)

The manager of the shelter wants the kittens distributed equally among the crates. How might that be done? How many kittens will end up in each crate? Need help fast!!!
Answers
Answer:
2 kittens per crate
Step-by-step explanation:
The kittens in a room at an animal shelter are arranged in five crates, as shown.
The manager of the shelter wants the kittens distributed equally among the crates. How might that be done? How many kittens will end up in each crate?
Crate 1 = 2 kittens
Crate 2 = 1 kitten
Crate 3 = 4 kittens
Crate 4 = 3 kittens
Crate 5 = 0 kitten
Total kittens = 2 + 1 + 4 + 3 + 0
= 10 kittens
To distribute them equally among the crates, divide the number of kittens by the number of crates
Kitten per crate = number of kittens / number of crates
= 10 kittens / 5 crates
= 2 kittens per crate
Kitten per crate = 2 kittens per crate

The probability that the first student chosen is a senior and the second student chosen is a sophomore is equal to 11/320.
What is probability?Probability is the likeliness of happening an event among all the events that are possible. It lies between 0and 1 and cannot be negative.
How to calculate probability?We have been given that the number of freshmen is 31, number of sophomores is 10, juniors is 17 and seniors be 22. Total number of persons be 31+10+17+22=80
let X denote person.
Probability that the first student is senior and second one is a sophomore=P(X=Senior)*P(X=Sophomore)
=22/80*10/80
=220/6400
=11/320
Hence the probability that the first student is senior and second one is a sophomore is 11/320.

Answers
Question:
Plot two points that are 8 units from Point B and also share the same x-coordinate as Point B
See attachment for grid
Answer:
See attachment for plot
Step-by-step explanation:
See comment for complete question
From the attached image, we have:
[tex]B = (-6,0)[/tex]
Required
2 points that are 8 units away and on the same x coordinate
Let the two points be [tex]C\ and\ D[/tex]
The first condition is that; C and D must be on the same x coordinate as B.
So, we have:
C = (-6,_)
D = (-6,_)
8 units from B implies that we add or subtract 8 from the y coordinate of B.
So, we have:
[tex]C = (-6,0+8)[/tex]
[tex]D = (-6,0-8)[/tex]
[tex]C= (-6,8)[/tex]
[tex]D= (-6,-8)[/tex]

Added Tax (VAT), the value of the watch will be Rs. 904.
Find the marked price of the watch.
Answers
Take x as the marked original price
x * (1-20/100) = 0.8x this is price after discount
0.8x * (1+13/100) = 0.904x this is the price after discount and Vat
0.904x=904 Rs
x = 904/0.904
x = Rs. 1000

Suppose that 20% of all students in a school make the Honor Roll. Which simulation best models a way to show how
students can be randomly selected and identified as being on the Honor Roll? WHY is that the best simulation?
A) Put 10 marbles in a bag, 8 red and 2 yellow. Draw out a marble at random 100 times, replacing the marble each
time.
B) Divide a spinner into 4 equal parts, labeled 1-4. Spin it 100 times. Let an even number represent Honor Roll and
an odd number represent not on the Honor Roll.
PLEASE REMEMBER TO STATE WHY
Answers
Answer:
A)
Step-by-step explanation:
The problem stated that 20 percent got in honor roll.
The key word in the problem is randomly selected.
Out of a and b, it's simply crossing out one of them.
B doesn't make sense, since if you spun a spinner 100 times, each side would have a probability of 25 percent. And that's if you only used one of the parts as an odd number.
Another way to think of it is that there are 2/10 yellow marbles, and 8/10 red.
2/10=20 percent.
8/10=80

Maria is making a fruit punch. There are 15.75 ounces of orange juice in a container. Maria pours 2.25 ounces of cranberry juice into the container each second. How many ounces of fruit punch are in the container after 9 seconds?
Answers
Answer:
20.25 ounces
Step-by-step explanation:
We are given 2.25 ounces of cranberry poured into the container per second. We need to find is how much that is after 9 seconds. (Note: This is different from the 15.75 ounces of orange.) There are many ways to solve this question (e.g If 2.25 is 1, then multiply 2.25 and 9 = 20.25) Now to solve this let's set up fractions; let "x" be the variable;
[tex]\frac{1}{2.25}=\frac{9}{x}[/tex]
Apply fraction: if [tex]\frac{a}{b}=\frac{c}{d}\mathrm[/tex] then [tex]a\cdot \:d=b\cdot \:c[/tex] (meaning cross multiply)
[tex]1\cdot \:x=2.25\cdot \:9[/tex]
Simplify
Multiply by 1[tex]1 x = 2 . 2 5 \cdot 9 \\\\ x = 2 . 2 5 \cdot 9[/tex]
Multiply the numbers[tex]x = 2 . 2 5 \cdot 9\\\\x=20.25[/tex]
Therefore, there are 20.25 ounces of fruit pouch in the container after 9 seconds.
