Answer:
[tex]\huge\boxed{\bf\:x = -\frac{4}{3}}[/tex]
Step-by-step explanation:
[tex]9x ^ { 2 } +24x+20=4[/tex]
Bring 4 to the left hand side of the equation .
[tex]9x^{2}+24x+20-4=0[/tex]
Subtract 4 from 20.
[tex]9x^{2}+24x+16=0[/tex]
Now, factorise it using the splitting-the-middle-term method .
[tex]9x^{2}+24x+16=0 \\9x^{2}+12x+12x+16 =0\\\left(9x^{2}+12x\right)+\left(12x+16\right)=0 \\3x\left(3x+4\right)+4\left(3x+4\right) =0\\\left(3x+4\right)\left(3x+4\right) = 0\\\left(3x+4\right)^{2} = 0[/tex]
Now since both the factors are the same, take one of them,
[tex]3x + 4 = 0\\3x = - 4\\\boxed{\bf\:x = -\frac{4}{3}}[/tex]

1. Mrs. Galicia is building a chicken farm in 2021 with an initial population of 3750 chickens. The farm grows at a rate of 2.15% annually. (a) Use the exponential growth model to write an equation that estimates the population t years after 2021. (b) Estimate the population of the town in 2036.
MUST SHOW ALL WORK
The exponential function is given by [tex]y = 3750(1.0215)^t[/tex], in 2036 the population is 5160.
What is an exponential function?An exponential function is in the form:
y = abˣ
Where y,x are variables, a is the initial value of y and b is the multiplication factor.
Let y represent the population of the chicken after t years after 2021.
In 2021 with an initial population of 3750 chickens, hence a = 3750.
The farm grows at a rate of 2.15% annually, hence b = 1 + 0.0215 = 1.0215
The exponential function is given by [tex]y = 3750(1.0215)^t[/tex]
In 2036, t = 2036 - 2021 = 15 years
[tex]y = 3750(1.0215)^{15}=5160[/tex]

what is the factor of these general trinomial 2x2 - 5x - 12??
Answer:
(x - 4)(2x + 3)
Step-by-step explanation:
Given
2x² - 5x - 12
Consider the factors of the product of the coefficient of the x² term and the constant which sum to give the coefficient of the x- term.
product = 2 × - 12 = - 24 and sum = - 5
The factors are - 8 and + 3
Use these factors to split the x- term
2x² - 8x + 3x - 12 ( factor the first/second and third/fourth terms )
= 2x(x - 4) + 3(x - 4) ← factor out (x - 4) from each term
= (x - 4)(2x + 3) ← in factored form
The factors are (x - 4) and (2x + 3)
The measure of arc qs is (4x – 18)°. what is the value of x? 40.5 49.5 94.5 180
The value of x such that arc QS subtends an angle of (4x – 18)° is 49.5°.
Since QS is the diameter.
What is the diameter?The diameter is the largest chord of a circle. It subtends an angle of 180° on the center.
So, the angle subtended by the arc QS on the center of the circle =180°
4x-18 = 180°
4x =198°
x= 49.5°
Therefore, The value of x such that arc QS subtends an angle of
(4x – 18)° is 49.5°.

On what interval/s is the graph decreasing?
Answer:
-1 < x < 1/3
Step-by-step explanation:
When the graph is decreasing, it means the the graph's slope is negative, or the graph is going towards negative infinity.
We see from the graph that it starts to decrease from -1 to 1/3. Therefore, our answer is -1 < x < 1/3.
Everywhere else on the graph is increasing.

(1) The length of UW is twice the length of YW
(2) The length of UY equals the length of YV
(3) Y is the midpoint of UW.

(4) Y is the midpoint of XV.
X
Answer:
Statement 4 is correct
Step-by-step explanation:
Here, we want to select which statement is true based on the given diagram;
The statement that must be true is that Y is the midpoint of XV
This is because, by bisection , we mean dividing into 2 equal parts
The line UW has divided the line XV into two equal parts
So this mean that Y is the midpoint of the line XV

Answer: 18 dollars
Step-by-step explanation:
Let x be the amount of money each girl recevied. Then, in total, they received 4*x dollars.
We can set up an equation for the information given.
4x - 4*12 = 24
4x - 48 = 24
4x = 72
x = 18
Therefore, each girl received 18 dollars.

Step-by-step explanation:
Sorry if this doesn't help! Hope you have a good day/night
Answer:
A
Step-by-step explanation:
There are only two plausible answers here, B or A. C and D are impossible because the angle is obviously an obtuse angle, an angle that is greater than 90.
If you're using a protractor, this is rather easy, just use the protractor to measure the angle. If you are not, it gets a bit complicated. I chose A without a protractor because B is only 20 degrees above 90, and it looks too wide to be only 20 degrees above a right triangle.
