The function that is represented by the graph is y = ∛(x + 3) + 3.
What is a function?
In mathematics, a function is a unique arrangement of the inputs (also referred to as the domain) and their outputs (sometimes referred to as the codomain), where each input has exactly one output and the output can be linked to its input.
The general form of a cube root function is -
y = a∛(x - h) + k and the parent graph is y = ∛x.
So the parent function is found.
The coordinate point for the parent function is -
(-1,-1) , (0,0) and (1,1).
In the graph it can be seen that the coordinate points are -
(-4,2), (-3,3) and (-2,4)
So the graph is first moved 3 units up and then moved three units left.
So, the coordinated become - (x + (-3) , y + 3)
So, the function that represents the graph is -
y = ∛(x + 3) + 3
Therefore, the function is y = ∛(x + 3) + 3.

There are 84 students in the Beachwood Middle School chorus. The number of girls in the chorus is 15 more than twice the number of boys.
Answer:
Expression for number of girls:
2b + 15
Equation for number of boys and girls:
b + (2b + 15) = 84
Number of boys
23
Number of girls
61
Step-by-step explanation:
b = number of boys
g = number of girls
b + g = 84
g = 2b+15
b + (2b + 15) = 84
3b + 15 = 84
3b = 69
b = 23
b + g = 84
23 + g = 84
g = 61

The statement that A triangular prism contains two parallel hexagonal faces is False
How to determine the true statementFrom the question, we have the following parameters that can be used in our computation:
A triangular prism contains two parallel hexagonal faces.
As a general rule, the parallel faces in a triangular prism are triangles
This is so because a triangular prism is a 3-dimensional object with a triangular base and three rectangular sides.
The two parallel faces of a triangular prism are congruent triangles, not hexagons.

Answer: 16
Step-by-step explanation:
To get from 3 to 12, you multiply by 4
To get from 5 to 20, you multiply by 4
So you just multiply 4 by 4 to get x
Answer:
x = 16
Step-by-step explanation:
since the triangles are similar then the ratios of corresponding sides are in proportion, that is
[tex]\frac{x}{4}[/tex] = [tex]\frac{20}{5}[/tex] = 4 ( multiply both sides by 4 to clear the fraction )
x = 16
The life (in hours) of a randomly chosen led light produced by a manufacturer is normally distributed with mean 1100 and standard deviation 70. Find the number of sample if the probability that the mean life is less than 1120 hours is 0.92
The sample size if the probability that the mean life is less than 1120 hours is 0.92 is given as follows:
n = 24.
How to obtain probabilities using the normal distribution?The z-score of a measure X of a variable that has mean symbolized by [tex]\mu[/tex] and standard deviation symbolized by [tex]\sigma[/tex] is obtained by the rule presented as follows:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score represents how many standard deviations the measure X is above or below the mean of the distribution, depending if the obtained z-score is positive or negative.Using the z-score table, the p-value associated with the calculated z-score is found, and it represents the percentile of the measure X in the distribution.By the Central Limit Theorem, the sampling distribution of sample means of size n has standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].The parameters for this problem are given as follows:
[tex]\mu = 1100, \sigma = 70, s = \frac{70}{\sqrt{n}}[/tex]
The p-value of Z when X = 1120 is of 0.92, hence Z = 1.405, and the sample size is obtained as follows:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]1.405 = \frac{1120 - 1100}{\frac{70}{\sqrt{n}}}[/tex]
[tex]20\sqrt{n} = 70 \times 1.405[/tex]
[tex]n = \left(\frac{70 \times 1.405}{20}\right)^2[/tex]
n = 24.

What is error analysis?
Error analysis is a technique used to track out errors in learner language, ascertain whether they are systematic, and (if possible) provide an explanation for why they occurred.
It is given that -
Line segment KM is the bisector of ∠LKJ.
Also, line segment LM = MJ.
According to the angle bisector theorem if a line is a bisector of an angle then the corresponding sides of the angle should be perpendicular to the third side which is getting bisected.
Although it is given that LM = MJ, but it is not known that if LM and MJ are perpendicular to the sides of ∠LKJ.

The value -2 is the rate of change of the linear equation.
What does the number -2 tell us about the pattern?A general linear equation is:
y = a*x + b
Where a is the rate of change and b is the y-intercept.
The rate of change tells us how the variable y changes when the variable x changes.
In this case we have:
y=-2x+10
So the "-2" is the rate of change, it tells us that each time that x increases 1 unit, the value of y decreases by 2 units.

Which three lengths could be the lengths
of the sides of a triangle?
A. 12 cm, 5 cm, 17 cm
B. 10 cm, 15 cm, 24 cm
C. 9 cm, 22 cm, 11 cm
D. 21 cm, 7 cm, 6 cm
Answer:
A. 12 cm, 5 cm, 17 cm
Step-by-step explanation:
For any three given lengths to be the sides of a triangle, they must satisfy the triangle inequality theorem. This theorem states that the sum of the lengths of any two sides must be greater than the length of the third side.
Let's check each of the options:
A. 12 cm, 5 cm, 17 cm: 5 + 12 = 17, which is greater than 17, so this is a valid triangle.
B. 10 cm, 15 cm, 24 cm: 10 + 15 = 25, which is greater than 24, so this is a valid triangle.
C. 9 cm, 22 cm, 11 cm: 9 + 11 = 20, which is not greater than 22, so this is not a valid triangle.
D. 21 cm, 7 cm, 6 cm: 7 + 6 = 13, which is not greater than 21, so this is not a valid triangle.
Therefore, the three lengths that could be the sides of a triangle are A (12 cm, 5 cm, 17 cm) and B (10 cm, 15 cm, 24 cm).

The equation representing the total cost is 15x + 750 and the total cost of restringing 32 lacrosse sticks would be $1230.
What is an equation?An equation is written in the form of variables and constants separated by the operation of multiplication and division,
An equation states that terms in different forms on both sides of the equality sign are equal.
Multiplication and division do not separate the terms of an equation.
Let, The number of lacrosse sticks be 'x' and the total cost is C(x).
Therefore, The equation representing the context is,
C(x) = 25x + 750.
The total cost of restringing 32 lacrosse sticks would be,

Isosceles triangles have congruent base angles making 63 = 3x +21
Solve for x.
All angles of a triangle add up to 180 making y = 180 - 63 - 63.
Isosceles because two sides are congruent. And acute because all angles are under 90.
