Select all the statements about the figure that MUST be true. Р Q 6n + 3 S 4n + 11 R PR=15 QS=21 QP=13 n=7 SR=27 QR=54
Answer:
Options (5) and (6)
Step-by-step explanation:
From the picture attached,
In right triangle ΔPSQ and ΔPSR,
PS ≅ PS [By reflexive property]
PQ ≅ PR [Given]
ΔPSQ ≅ ΔPSR [By HL property of congruence]
Therefore, QS ≅ SR [CPCTC]
(6n + 3) = (4n + 11)
6n - 4n = 11 - 3
2n = 8
n = 4
QS = (6n + 3)
= 6×4 + 3
= 27
SR = (4n + 11)
= 4×4 + 11
= 16 + 11
= 27
QR = QS + SR
= 27 + 27
= 54
Therefore, Options (5) and (6) are the correct options.

Stan evaluated a function with a value and got 3 as the result. He wrote the entire process as a sentence: The function , when evaluated with , gives the value 3.
The function f(x) = x^2-1 when evaluated with 2, gives the value 3.
What is a function?A function can then be defined as a set of ordered pairs. Function is an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
For the given situation,
Stan evaluated a function with a value and got 3 as the result.
For this statement, we can frame many functions with different inputs.
Let us consider the function,
(1) [tex]f(x)=2x-3[/tex]
Now substitute x = 3,
⇒ [tex]f(3)=2(3)-3[/tex]
⇒ [tex]f(3)=6-3\\[/tex]
⇒ [tex]f(3)=3[/tex]
(2) [tex]f(x)=x^{2} -1\\[/tex]
Now put x = 2,
⇒ [tex]f(2)=2^{2}-1[/tex]
⇒ [tex]f(2)=4-1[/tex]
⇒ [tex]f(2)=3[/tex]
Similarly we can make many functions that has the value 3 as the result.
Hence we can conclude that the function f(x) = x^2-1 when evaluated with 2, gives the value 3.

What are the solutions to the quadratic equation?
Answer: Choice C) [tex]x = 4\pm2\sqrt{10}[/tex]
This is the same as saying [tex]x = 4+2\sqrt{10} \ \ \text{ or } \ \ x = 4-2\sqrt{10}[/tex]
=============================================================
Explanation:
First get everything to one side
x^2 + 13 = 8x + 37
x^2 + 13 - 8x - 37 = 0
x^2 - 8x - 24 = 0
Here we have a quadratic in the form ax^2+bx+c = 0
Note how a = 1, b = -8, c = -24
Those values are plugged into the quadratic formula below
[tex]x = \frac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\x = \frac{-(-8)\pm\sqrt{(-8)^2-4(1)(-24)}}{2(1)}\\\\x = \frac{8\pm\sqrt{160}}{2}\\\\x = \frac{8\pm\sqrt{16*10}}{2}\\\\x = \frac{8\pm\sqrt{16}*\sqrt{10}}{2}\\\\x = \frac{8\pm4*\sqrt{10}}{2}\\\\x = \frac{2(4\pm2\sqrt{10})}{2}\\\\x = 4\pm2\sqrt{10}[/tex]
This shows the answer is choice C.
The plus minus breaks down that equation these two solutions
[tex]x = 4+2\sqrt{10} \ \ \text{ or } \ \ x = 4-2\sqrt{10}[/tex]

a) Find the class interval that contains the median.
b) Work out an estimate for the mean number of hours.
Answer=
a= 2<h<3
b=2.2
a) The class interval that contains the median. is 1 ≤ h ≤ 2.
b) The mean number of hours is, 1.8 h
What is mean and median?The arithmetic mean is found by adding the numbers and dividing the sum by the number of numbers in the list. And, The median is the middle value in a list ordered from smallest to largest.
Now,
a) First find the median as,
Median = 30/2
= 15
Now, 6 + 13 = 19 > 19
So, The class interval that contains the median be 1 ≤ h ≤ 2.
b) Let us take the middle of the range as the average;
⇒ (6 × (1 - 0)/2 + 13 × (2 + 1)/2 + 7 ×(2 + 3)/2 + 4 × (3 + 4)/2 ) / 30
⇒ (3 + 19.5 + 17.5 + 14) / 30
⇒ 54/30
⇒ 1.8 hours
So, The value of mean is 1.8.

Maritza says that the number y is equal to 5 less than -5 times x. Which of the following equations could be used to find the value of y?
Answer:
y= -5x-5
Step-by-step explanation:
Y is equal to 5 less than -5 times x, which means it is 5 less than -5x.
If y is 5 less than -5x, that means it is equal to -5x-5.
If you were to put that in an equation, it would be y= -5x-5

A new bank customer with $3,000 wants to open a money market account. The bank is offering a simple interest rate of 1.1%. How much will the customer earn in one year?
Given:
Principal amount = $3000
Rate of simple interest = 1.1%
To find:
The amount that the customer will earn in one year.
Solution:
Formula for simple interest is
[tex]I=P\times r\times t[/tex]
where, P is principal, r is rate of interest and t is time in years.
Substituting P=3000, r=0.011 and t=1, we get
[tex]I=3000\times 0.011\times 1[/tex]
[tex]I=33[/tex]
Therefore, the customer will earn $33 in one year.

1; A coordinate grid with a point at 3 units to the right and 4 units down from the origin labeled movie theater.
2; A coordinate grid with a point at 3 units to the left and 4 units down from the origin labeled movie theater.
3; A coordinate grid with a point at 3 units to the right and 4 units up from the origin labeled movie theater.
4; A coordinate grid with a point at 3 units to the left and 4 units up from the origin labeled movie theater.
Answer:
The 1st choice
Step-by-step explanation:
Let a point is defined as P(a,b).
If a>0, then point is a units right from origin and if a<0, then then point is a units left from origin.
If b>0, then point is b units up from origin and if b<0, then then point is b units down from origin.
It is given that the location of the movie theater is at (2, −3).
In the given point a=2>0 and b=-3<0.
A coordinate grid with a point at 2 units to the right and 3 units down from the origin labeled movie theater.

There is a new kids movie out that everyone is seeing. On the first night the theater sold 200 tickets total. Adult tickets are $8.50, child tickets are $3.50, and they made $1,500 dollars that night. How many adults and how many children saw the movie?
9514 1404 393
Answer:
160 adults40 kidsStep-by-step explanation:
Let 'a' represent the number of adult tickets sold. Then (200-a) is the number of child tickets sold. The total revenue is ...
8.50a +3.50(200 -a) = 1500
5a = 800 . . . . . . . . . . . . . . . . . . . subtract 700 and collect terms
a = 160
(200-a) = 40
160 adults and 40 children paid to see the movie.
Answer:
160 adults and 40 children saw the movie on the first night.
Step-by-step explanation:
Total number of tickets sold = 200
Let the total number of adults be 'x'
So, Total number of children = 200 - x
Cost of adult tickets = $8.50
Cost of child tickets = $3.50
Total sum made on first night = $1,500
Total sum made on first night is equal to total cost of adult tickets + total cost of child tickets
[tex] \longrightarrow [/tex] 8.50x + 3.50(200 - x) = 1500
[tex] \longrightarrow [/tex] 8.5x + 700 - 3.5x = 1500
[tex] \longrightarrow [/tex] 8.5x - 3.5x = 1500 - 700
[tex] \longrightarrow [/tex] 5x = 800
[tex] \longrightarrow [/tex] x = [tex] \sf \dfrac{800}{5} [/tex]
[tex] \longrightarrow [/tex] x = 160
[tex] \therefore [/tex] Total number of adults = 160
Total number of children = 200 - 160 = 40
