Answer:
m∠QRS = 52°
Step-by-step explanation:
From the given figure,
In right triangles ΔRQT and ΔRST,
QT = TS = 7.5 units [Given]
RT ≅ RT [Reflexive property]
ΔRQT ≅ ΔRST [By HL theorem of congruence]
Therefore, m(∠QRT) = m(∠SRT) = 26° [CPCTC]
m(∠QRS) = 2m(∠QRT)
= 2×(26°)
= 52°

What is the measure of the missing angle?
Answers
Answer:
47
Step-by-step explanation:
Hey There!
So remember all of the angles in a triangle will add up to equal 180
So to find the missing angle we subtract the given angles (65 and 68) from 180
180-65-68-47
so we can conclude that the measure of the missing angle is 47

Step-by-step explanation:
how to find the hypotenuse is a^2 + b^2 = c^2
a = 9
b = 6
9^2 + 6^2
9 x 9 = 81
6 x 6 = 36
81 + 36 = 117
177 = c^2
find the square root of 177 = 10.81665383 about 10.8

Dave divided the number line into 8 parts and labeled the location for 18 on the number line. J Did Dave divide the number line correctly? Why or why not?
Answers
Answer:
Yes, he divided correctly
Step-by-step explanation:
Given
[tex]Parts = 8[/tex]
[tex]Location = \frac{1}{8}[/tex]
Required
Was his calculation correct?
Yes, he divided the number line correctly.
Given that the number of intervals on the number line is x.
When divided into 8 parts, we have:
[tex]Location = \frac{x}{8}[/tex]
[tex]Location = \frac{1}{8}x[/tex]
This means that each point on the number line will be located at 1/8 interval between one another.
Hence, Dave is correct

Answers
Answer:
x = 20
Step-by-step explanation:
You can solve this problem using similar triangles; you know the triangles are similar due to the AAA property because of the Corresponding Angles Theorem.
To find x, you need to identify what sides 8 and x correspond to:
8 corresponds to 14 (6 + 8)
x corresponds to (x + 15)
Now, you need to find the scale factor by dividing 14 by 8:
14 ÷ 8 = 7/4
At this point, you can write and solve an equation for x:
7/4x = x + 15
3/4x = 15 (subtract x from both sides)
x = 20 (multiply both sides by 3/4)

Part A: Let y represent the number of rabbits after x years. Which functioncan be used to model y as a function of x, where x is a non negative number ?
А. y = 10 (3) ^ (x - 1)
В. y = 10 (3) ^ x
C. y = 3 (10) ^ (x - 1)
D . y = 3 (10) ^ x
Answers
Answer:
y = 10(3)x
Step-by-step explanation:
The exponential function that can represent the population of rabbits after [x] years is y = 10(3)ˣ.
What do you mean by domain and range of a function?For any function y = f(x), Domain is the set of all possible values of [x] for which [y] exists. Range is the set of all values of [y] that exists for the given domain.
Given is rate of increase of a rabbit's population.
The exponential function that can represent the population of rabbits after [x] years can be written as -
y = 10(3)ˣ
Refer to the graph attached.
Hence, the exponential function that can represent the population of rabbits after [x] years is y = 10(3)ˣ.

(3x + 7)(3x – 9)
Answers
Answer:
9x² - 6x - 63
Step-by-step explanation:
Use the FOIL method. FOIL stands for First, Outside, Inside, Last.
Multiply following the FOIL:
3x * 3x = 9x²
3x * -9 = -27x
7 * 3x = 21x
7 * -9 = -63
9x² - 27x + 21x - 63
Combine like terms.
9x² (-27x + 21x) - 63
9x² - 6x - 63
9x² - 6x - 63 is your answer.
~
9x^2 - 27x+21x−63
9x^2 + (27x+21x) - 63
9x^2 - 6x - 63
9x2 - 52x + 33 = -10x - 16
Quadratic Equation
Answers
Answer:
x=7/3 or x=2.33
Step-by-step explanation:
9x^2 - 52x + 33 = -10x - 16
Okay, lets Start by converting this into standard form, which is: ax^2 + bx + c = 0.
Add 10x+16 on both sides of the equation, and simplifying.
9x^2 - 52x + 33 + 10x + 16 = -10x - 16 + 10x + 16
9x^2 - 42x + 49 = 0
Guess What! This equation is a Perfect Square Trinomial.
For a Perfect Square Trinomial, you will be able to take the square root of the first and third terms, and the coefficient of the second term will be twice the square root of the third term. The “sign” of your second term in your answer will be the same as the linear term sign.
So this is (3x*3x) + (3x * -7 * 2) + (7 * 7) = 0
So, we can rewrite this as (3x - 7)^2=0
Now, To solve, We can set each factor equal to 0, and solve.
*Since we have a Perfect Square Trinomial, You will get one solution, or value, for x.*
Add 7 on both sides.
3x - 7 = 0
+7 +7
----------------
3x=7
Divide by 3 on both sides.
3x/3 = 7/3
x=7/3
As a decimal: 2.33...

2x=4
x=4/2=2
when 3x-2=-(x+2)
3x-2=-x-2

x=0
it is rejected as 0-2≠|0+2|
