Answer 5. f(x)≥27
Answer:
1. All real numbers
Step-by-step explanation:
Simplifies to f(x) = 6x - 63, it will cross all x and y values.
The domain and range of the given function are all real numbers
We have given that,
f(x)=3(x−15)2+27
f(x)=(3x-45)2+27
f(x)=6x-90+27
What is the domain?The domain is the set of points at which the function is defined.
What is the range?
The range of a set of data is the difference between the largest and smallest values. The difference here is specific, the range of a set of data is the result of subtracting the sample maximum and minimum.
To f(x) = 6x - 63, it will cross all x and y values.

Coach Wu has a total of 30 soccer balls. 9 soccer balls are white the remaining soccer balls are one of three different colors (blue, pink, or green) there is an equal number of blue, pink, and green balls. How many green soccer balls does Coach Wu have?
Answer:
Number of green soccer balls = 7
Step-by-step explanation:
Total number of soccer balls = 30
Number of white balls = 9
Number of soccer balls excluding number of white balls = 30 - 9 = 21
Also, the remaining soccer balls are one of three different colors (blue, pink, or green) such that there is an equal number of blue, pink, and green balls.
Number of blue balls = Number of pink balls = Number of green balls = [tex]\frac{21}{3}=7[/tex]
Therefore,
Number of green soccer balls = 7

Jet bought a computer that was 20% off. If the original price of the computer was $785, how much did Jet save? How much did Jet pay?
785·20%=157
785-157=628
Answer:
You will pay $628 for a item with original price of $785 when discounted 20%. In this example, if you buy an item at $785 with 20% discount, you will pay 785 - 157 = 628 dollars.

Jasmine will buy the same number of stamps every month to add to a stamp collection her grandfather gave her. The table shows the number of stamps Jasmine will have at the end of x months. How many stamps was Jasmine given, and how many stamps will she buy every month?
Jasmine was given 65 stamps, and she will buy 5 stamps every month.
Jasmine was given 60 stamps, and she will buy 65 stamps every month.
Jasmine was given 5 stamps, and she will buy 60 stamps every month.
Jasmine was given 60 stamps, and she will buy 5 stamps every month
Answer:
Option (4)
Step-by-step explanation:
If we draw a graph against x(Number of months) and y(Number of stamps),
We will get a straight line.
Let the equation of straight line be,
y = mx + b
Here, m = Stamps purchased per month
b = Jasmine was given stamps initially
From the table attached,
m = [tex]\frac{70-65}{2-1}[/tex] = 5 stamps per month
Therefore, equation of the line will be,
y = 5x + b
Since, a point (1, 65) lies on this line,
65 = 5(1) + b
b = 60
That means she was given 60 stamps initially.
Option (4) will be the answer.

Are the events "selecting a female" and "selecting a students who has brown eyes" independent?
Answer:
No, the events are not independent.
Step-by-step explanation:
Suppose that there are two events, A and B.
Such that first happens the event A and then the event B.
If the outcome of event A affects the probabilities for the different outcomes of event B, then the events are dependent.
In this case, if we have only the event "selecting a student who has brown eyes" (at random)
The probability is equal to the quotient between the total number of students with brown eyes, and the total number of students, then this probability is:
P = 91/200 = 0.455...
Now, if we first impose the "selecting a female", now when we want to select a student with brown eyes we will look only at the female students.
In this case, there are 32 with brown eyes and a total of 90 female students, then the probability of selecting a female with brown eyes at random is:
P = 32/90 = 0.355...
So the probability is different, which means that the events "selecting a female" and "selecting a student who has brown eyes" are not independent.

Answer: Yes these triangles are similar
Step-by-step explanation:
First lets write down what we know just to make life easier
x=9
TL should be similar to CH
LY should be similar to KH
The angles should be equal due to SAS
So the first thing we know is true is the fact that they have equal angles. Now we have to find out if the sides are similar or if they change by the same ratio to the other. If TL is similar to CH and TL=25 and CH=10 what is the change in size or dilation. Division should do the trick so 25/10=2.5 so TY is greater than CH by a factor of 10. Which means that LY should also be greater than KH by a factor of 2.5. If we are told that x=9 than side LY or 4(9)-1=35 and KH 9+5=14
So side KH is 14 and LY is 35. Now to check if they are similar then KH should be greater by a factor of 2.5. If this is not true than the sides are not similar. 35/2.5=14
Since 35 divided by 2.5 is 14 we can tell both sides TL and LY are greater than KH and CH by a factor of 2.5
Hope this helps.

Among the following, which one is not in similarity theorem.
A. SSS similarity theorem
B. SS similarity theorem
C. SAS similarity theorem
D. AA similarity theorem
Answer:
If two triangles are similar it means that all corresponding angle pairs are congruent and all corresponding sides are proportional. However, in order to be sure that two triangles are similar, you do not necessarily need to have information about all sides and all angles.

The value of 5% equals 5/100 or 0.005. Convert the following percentages into one-hundredths and then into a decimal: 75%, 20%, 0.8%?
Answer:
75/100, 20/100, 8/1000
