11. Write the equation for the graph
This is the same as writing y = sqrt(4(x+5)) - 1
===============================================
Explanation:
The given graph appears to be a square root function.
The marked points on the curve are:
(-4,1)(-1,3)(4,5)Reflect those points over the line y = x. This will have us swap the x and y coordinates.
(-4,1) becomes (1,-4)(-1,3) becomes (3,-1)(4,5) becomes (5,4)Recall the process of reflecting over y = x means we're looking at the inverse. The inverse of a square root function is a quadratic.
----------
Let's find the quadratic curve that passes through (1,-4), (3,-1) and (5,4).
Plug the coordinates of each point into the template y = ax^2+bx+c.
For instance, plug in x = 1 and y = -4 to get...
y = ax^2+bx+c
-4 = a*1^2+b*1+c
-4 = a+b+c
Do the same for (3,-1) and you should get the equation -1 = 9a+3b+c
Repeat for (5,4) and you should get 4 = 25a+5b+c
We have this system of equations
-4 = a+b+c-1 = 9a+3b+c4 = 25a+5b+cUse substitution, elimination, or a matrix to solve that system. I'll skip steps, but you should get (a,b,c) = (1/4, 1/2, -19/4) as the solution to that system.
In other words
a = 1/4, b = 1/2, c = -19/4
We go from y = ax^2+bx+c to y = (1/4)x^2+(1/2)x-19/4
----------
Next we complete the square
y = (1/4)x^2+(1/2)x-19/4
y = (1/4)( x^2+2x )-19/4
y = (1/4)( x^2+2x+0 )-19/4
y = (1/4)( x^2+2x+1-1 )-19/4
y = (1/4)( (x^2+2x+1)-1 )-19/4
y = (1/4)( (x+1)^2-1 )-19/4
y = (1/4)(x+1)^2- 1/4 - 19/4
y = (1/4)(x+1)^2 + (-1-19)/4
y = (1/4)(x+1)^2 - 20/4
y = (1/4)(x+1)^2 - 5
The equation is in vertex form with (-1,-5) as the vertex. It's the lowest point on this parabola. Placing it into vertex form allows us to find the inverse fairly quickly.
----------
The last batch of steps is to find the inverse.
Swap x and y. Then solve for y.
y = (1/4)(x+1)^2 - 5
x = (1/4)(y+1)^2 - 5
x+5 = (1/4)(y+1)^2
(1/4)(y+1)^2 = x+5
(y+1)^2 = 4(x+5)
y+1 = sqrt(4(x+5))
y = sqrt(4(x+5)) - 1
I'll let the student check each point to confirm they are on the curve y = sqrt(4(x+5)) - 1.

Of their first 18 games of the season, the
Chicago Cubs lost 4 games and won the
others. What percent of the games have
they won?
The percentage of the games the club has won is P = 77.78 %
What is Percentage?A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %
The difference between an exact value and an approximation to it is the approximation error in a data value. Either an absolute error or a relative error might be used to describe this error.
Percentage change is the difference between the measured value and the true value , as a percentage of the true value
Percentage change =( (| Measured Value - True Value |) / True Value ) x 100
Given data ,
Let the total number of games = 18
The number of games they lost = 4
So , the number of games they won = 14 games
Now , the percentage of games they won = ( 14 / 18 ) x 100
On simplifying the equation , we get
A = 0.7778 x 100
A = 77.78 %
Hence , the percentage is 77.78 %

-8(-4+n)<-40 help me pls
Answer:
n > 1
Step-by-step explanation:
To solve this inequality, we need to get the variable "n" alone. Follow PEMDAS to do so :
Parenthesis
Exponent
Multiplication
Division
Addition
Subtraction
We can first distribute the -8 to -4 and n to get rid of the parenthesis.
((-8)-4 + (-8)n)
-32 + -8n < -40
Now add 32 to both sides.
-40 + 32 = -8
-8n < -8
Now divide -8 by both sides, don't forget to switch the inequality sign since you're dividing by a negative number.

A factory manager wishes to install types of machines, small and large. A small machine needs 2 operators and occupies 4m² of floor space. A large machine needs 3 operators and accupies 8m³of floor space. There are up to 30 operators available and 72m² of floor space. At Least 4small machines and at least 5 large machines must be installed.
a) Taking X to be the number of small machine, and y as the number of large machine to be installed, write down. the four major inequalities required.
b) Draw a graph to show the region satisfying the inequalities
c) Determine the maximum number of machines he can install .
d) If the profit made by each small machine is 250,000 and by the large type is 300,000 per week, find the maximum profit the factory can make in one week and the number of machines of each type that should be installed.

b) We have drawn the graph.
c) The maximum number of machines that can be installed is 11.
d) The maximum profit is 2,500,000.
What is inequality?
An inequality is a mathematical statement that shows the relationship between two values where one value is either greater than or less than the other value. It is represented by symbols such as >, <, ≥, or ≤. For example, if x is a variable and we want to express that x is greater than 5, the inequality would be written as x > 5.
a) X >= 4 and Y >= 5, 2X + 3Y <= 30 and 4X + 8Y <= 72
b) To graph the region, we can plot the lines that define the inequalities and shade the area that satisfies all of them.
c) Solving the system of inequalities graphically, we find the maximum number of machines that can be installed is 11 (6 small and 5 large).
d) To find the maximum profit, we need to substitute the number of machines into the profit equation. P = 250,000X + 300,000Y. Plugging in X = 6 and Y = 5, we find the maximum profit to be 2,500,000.
Hence,
a) X >= 4 and Y >= 5, 2X + 3Y <= 30 and 4X + 8Y <= 72
b) We have drawn the graph.

The space shuttle carries c pounds of cargo, and each piece of cargo weighs 162.68 pounds. Which of the following expressions represents the number of pieces of cargo?
The expression which represents the number of pieces of cargo is c/162.68 = x, where c is the weight of the cargo in pounds, and x is the number of pieces of cargo.
Given that the space shuttle carries c pounds of cargo, and each piece of cargo weighs 162.68 pounds. We have to determine which of the following expressions represents the number of pieces of cargo.
Let's assume that the number of pieces of cargo be x.
Therefore, the weight of x pieces of cargo will be 162.68x = weight of cargo. The expression which represents the number of pieces of cargo can be written as: c/162.68 = x
This is because the total weight of the cargo is c pounds, and we know that each piece weighs 162.68 pounds.
Therefore, to find the number of pieces, we can divide the total weight by the weight of each piece, which gives us the expression c/162.68 = x, where x is the number of pieces of cargo.

Suppose that a box contains 8 cameras and that 4 of them are defective. A sample of 2 cameras is selected at random. Define the random variable variable x as the number of defective cameras in the sample. What is the probability distribution for x?
The probability distribution for x is:
x P(x)
0 0.214
1 0.571
2 0.214
How can we determine the probability distribution for x?Since there are 8 cameras in the box, the total number of ways to choose 2 cameras from the box is given by the combination formula:
C(8,2) = 8!/(2!×(8-2)!) = 28
So there are 28 possible ways to choose a sample of 2 cameras.
Now, let's calculate the probability of each possible value of x:
When x = 0, both cameras in the sample are non-defective. The number of ways to choose 2 non-defective cameras from the 4 non-defective cameras in the box is given by the combination formula:
C(4,2) = 4!/(2!×(4-2)!) = 6
So the probability of x = 0 is:
P(x=0) = (number of ways to choose 2 non-defective cameras)/(total number of ways to choose 2 cameras)
= 6/28
= 0.214
When x = 1, one camera in the sample is defective and the other is non-defective. The number of ways to choose 1 defective camera from the 4 defective cameras in the box and 1 non-defective camera from the 4 non-defective cameras in the box is given by the product of the corresponding combinations:
C(4,1) × C(4,1) = 4×4 = 16
So the probability of x = 1 is:
P(x=1) = (number of ways to choose 1 defective camera and 1 non-defective camera)/(total number of ways to choose 2 cameras)
= 16/28
= 0.571
When x = 2, both cameras in the sample are defective. The number of ways to choose 2 defective cameras from the 4 defective cameras in the box is given by the combination formula:
C(4,2) = 4!/(2!×(4-2)!) = 6
So the probability of x = 2 is:
P(x=2) = (number of ways to choose 2 defective cameras)/(total number of ways to choose 2 cameras)
= 6/28
= 0.214
Therefore, the probability distribution for x is:
x P(x)
0 0.214

A local meteorologist announces to the town that there is a 68% chance there will be a blizzard tonight. What are the odds there will not be a blizzard tonight? Write your answer as 1:2 which is reduced as much as possible.
Answer:
Step-by-step explanation:
If there is a 68% chance of a blizzard tonight, then the probability of a blizzard is 0.68.
The odds in favor of an event happening are defined as the ratio of the probability of the event happening to the probability of the event not happening. In this case, the odds in favor of a blizzard are:
odds in favor of blizzard = P(blizzard) / P(no blizzard)
We can use the fact that the probabilities of all possible outcomes must add up to 1 to find the probability of no blizzard:
P(no blizzard) = 1 - P(blizzard) = 1 - 0.68 = 0.32
Therefore, the odds in favor of no blizzard are:
odds in favor of no blizzard = P(no blizzard) / P(blizzard) = 0.32 / 0.68
Simplifying the fraction by dividing both numerator and denominator by 0.32, we get:
odds in favor of no blizzard = 0.32 / 0.68 = 8/17
The odds in favor of no blizzard are 8:17, which is reduced as much as possible.
