g^(-1) => x + 2 = 1/g(x)
g^(-1) => g(x)(x + 2) = 1

Coach Gannon Bought 8 Bags Of Sunflower Seeds For The Baseball Game. Each Bag Has 2 1/4 Cups Of Seeds. If Coach Gannon Has 12 Baseplayers On The Team, How Many Cups Of Seeds Can Each Player Have?
Answers
First, let’s multiply 8 and 2 1/4 together. You would get 18.
Next, you would divide that by 12. You would get 1.5 cups.
Last, you turn that into fraction form, if you need to. You would get 1 1/2 cups.
The answer is 1.5 or 1 1/2. Please mark Brainliest if this helped you. :))

Inequality
Answers
Answer:
4). [tex]y<\frac{1}{2}x-4[/tex] (look at my explanation for how to graph)
5.) [tex]y<\frac{?}{?}x+?[/tex] (look at my explanation for how to get the correct numbers)
6.) [tex]x\geq 2[/tex] (look at my explanation for how to graph)
Step-by-step explanation:
Question 4:
Solving for y:
First it's better if you solve for y then graph, it's easier that way.
[tex]x-2y>8\\-2y>-x+8\\y<\frac{1}{2}x-4[/tex]
As you might notice the greater than sign flipped, that doesn't always happen. It only happens when you are dividing by a negative number.
Graphing the inequality:
When you start graphing you should always start by plotting the y-intercept. Which in this case it's [tex](0,-4)[/tex]. Then starting from that point you would go up 1 unit then right 2 units then plot the new point because the slope is [tex]\frac{1}{2}[/tex]. The 1 would be the up and down as for the 2 it will be the right and left. This goes up 1 and right 2 because it's positive. So you keep going creating new points as you go then when you reached the end of the graph you would go back to [tex](0,-4)[/tex] and do the opposite so you will do down 1 then left 2. When you run out of room you will have to draw a line, but be careful the line has to be dotted because the solid lines are used for the greater/less than or equal to signs. Then make sure to add arrows at each side of the dotted line to indicate that this line is infinite.
Question 5:
I'm very sorry but I can't see the picture since it's a bit blurry. So I'll try to explain how to write the inequality the best I can. So first we need to know the y-intercept it should be the point directly on the y-axis. Then find the slope by seeing how it gets to the next perfect point. I can tell you that the slope will be positive. Also for the sign it's dotted that means the sign is [tex]<[/tex]. So the inequality should look something like this [tex]y<\frac{?}{?}x+?[/tex]. Make sure you have the signs correct too don't change the ones I already put in.
Question 6:
For this one the inequality will look like this [tex]x\geq 2[/tex]. Then for the graph you will plot [tex](2,0)[/tex]. Then make a solid line that goes vertically since the only x-value is 3 the y-value will be changing without the x. Then for the shading you will shade the right side of the line.

Mean is fairly simple. You add up all the numbers, then divide it by how many numbers you have.
Step-by-step explanation:
Take for example, you have 1, 2, 3, 4, 5
Add all those numbers up.
1+2+3+4+5
You get 15.
To get the mean, you simply divide 15 by 5.

B. There is sufficient evidence that the mean of the pressure required to open a certain valve has changed.
Step-by-step explanation:
We make this conclusion based on these reasons:
We are told that the "null hypothesis was rejected" after the "manager feels that the pressure variability has changed., meaning the null hypothesis was the opposite of what occurred; that is to say, it is the alternate hypothesis that proved true instead."changes in the manufacturing process" form what can be called "sufficient evidence" that the mean of the pressure required to open the valve has changed, thereby going against the null hypothesis.It is based on the above reasons that the null hypothesis was rejected.

Which of the three situations given below is best modeled by an exponential function?
I'm not good at math :/
Answers
The correct answer is (b) a bacteria culture triples in size every day describes a exponential function.
What is a function?A relation is a function if it has only One y-value for each x-value.
The growth of a population, bacteria culture, or puppy can be modeled by an exponential function if the growth rate is proportional to the current size.
In other words, if the growth rate is constant, then the growth can be modeled by an exponential function.
Out of the three situations given, option (ii) is the only one that has a constant growth rate, since the bacteria culture triples in size every day. This means that the growth rate is constant at 200% per day.
Option (i) has a growth rate that is not constant but increases every year, so it is not best modeled by an exponential function.
Option (iii) also has a growth rate that is not constant, since the puppy grows by a fixed amount of 2 pounds every month regardless of its current weight.
Therefore, the correct answer is (b) a bacteria culture triples in size every day describes a exponential function.

In the right ∆ABC, the hypotenuse AB = 17 cm. M is the midpoint of the hypotenuse. Find the legs if PAMC=32 cm and PBMC=25 cm
Answers
Answer:
The length of the legs is 8.64cm and 14.64cm respectively
Step-by-step explanation:
I've added an attachment to aid my explanation.
At different intervals, I'll be making reference to it.
Given
[tex]AB = 17[/tex]
[tex]PAMC = 32[/tex]
[tex]PBMC = 25[/tex]
From the attachment, we have:
[tex]y + z = AB[/tex]
Since, M is the Midpoint
[tex]y = z = \½AB[/tex]
Substitute 17 for AB
[tex]y = z = \½ * 17[/tex]
[tex]y = z = 8.5[/tex]
Also, from the attachment
[tex]v + x + z = PAMC[/tex]
[tex]v + x + y = 32[/tex]
Substitute 8.5 for y
[tex]v + x + 8.5 = 32[/tex]
[tex]v + x = 32 - 8.5[/tex]
[tex]v + x = 23.5[/tex] --------- (1)
Also, from the attachment
[tex]v + w + z = 25[/tex]
Substitute 8.5 for z
[tex]v + w + 8.5 = 25[/tex]
[tex]v + w = 25 - 8.5[/tex]
[tex]v + w = 17.5[/tex] ----------- (2)
Subtract (2) from (1)
[tex]v - v + x - w = 23.5 - 17.5[/tex]
[tex]x - w = 6[/tex]
Make x the subject
[tex]x = 6 + w[/tex]
Apply Pythagoras Theorem:
We have that:
[tex]AB^2 = AC^2 + BC^2[/tex]
The above can be replaced with
[tex]17^2 = x^2 + w^2[/tex] (see attachment)
[tex]289 = x^2 + w^2[/tex]
Substitute 6 + w for x
[tex]289 = (6 + w)^2 + w^2[/tex]
[tex]289 = 36 + 12w + w^2 + w^2[/tex]
[tex]289 - 36 = 12w + 2w^2[/tex]
[tex]253 = 12w + 2w^2[/tex]
Reorder
[tex]2w^2 + 12w - 253 = 0[/tex]
Solve using quadratic equation:
[tex]w = \frac{-b \± \sqrt{b^2 - 4ac}}{2a}[/tex]
Where
[tex]a = 2[/tex]
[tex]b = 12[/tex]
[tex]c = -253[/tex]
[tex]w = \frac{-12 \± \sqrt{12^2 - 4 * 2 * -253}}{2 * 2}[/tex]
[tex]w = \frac{-12 \± \sqrt{144 + 2024}}{4}[/tex]
[tex]w = \frac{-12 \± \sqrt{2168}}{4}[/tex]
[tex]w = \frac{-12 \± 46.56}{4}[/tex]
Split:
[tex]w = \frac{-12 + 46.56}{4}[/tex] or [tex]w = \frac{-12 - 46.56}{4}[/tex]
[tex]w = \frac{34.56}{4}[/tex] or [tex]w = \frac{-58.56}{4}[/tex]
[tex]w = 8.64[/tex] or [tex]w = -14.64[/tex]
But length can't be negative
So:
[tex]w = 8.64[/tex]
Recall that: [tex]x = 6 + w[/tex]
[tex]x = 6 + 8.64[/tex]
[tex]x = 14.64[/tex]
Hence, the length of the legs is 8.64cm and 14.64cm respectively

Answers
Answer:
X = 27 bags
Step-by-step explanation:
Given the following data;
Ratio of mulch to fertilizer = 1:6
Quantity of mulch = 4.5 bags
Let the quantity of fertilizer = x
Therefore,
1 mulch = 6 fertilizer
4.5 mulch = x fertilizer
Cross multiplying, we have
x = 6 * 4.5
x = 27
Therefore, if she uses 4.5 bags of mulch, then she should use 27 bags of fertilizer.
