the graph shows the relationship between the hours rachel studied and the exam grades she earned
Plz answer
Answers
Answer:
11. This is a function because every input, the number of hours studied, has one output, the grade.
12. Looking at the graph it already has a point for 2 hours. Plotting another 2 hour point would no longer make it a function. This is because there are now two outputs for one input.
Step-by-step explanation:
A function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.
The given relationship is a function by vertical line test and by plotting the grade for 2 hours will remove the function.
What is a function?A certain kind of relationship called a function binds inputs to essentially one output.
The machine will only accept specified inputs, described as the function's domain, and will potentially produce one output for each input.
Given the graph,
If we apply the vertical line test it means we will draw vertical lines at every plotted point.
For me, in this function, the number of points on every line must be 1.
Since in the graph for each input only one output so it is a function.
Now if we plot the grade for 2 hours the number of grades for 2 hours will be 2 so it will remove the function because it gives two outputs unless it is not the same point it's that's 70.
Hence "The given relationship is a function by vertical line test and by plotting the grade for 2 hours will remove the function".

If the middle term of a quadratic trinomial is negative and the last term is negative, then
the sum of the factors for the middle term must be __
Answers
Answer:
Negative
Step-by-step explanation:
Years of Factoring:
What the problem tells us is that we have:
X^2 - 4x - 3
or something along these lines. If we factor this we get:
(X-4)(X+1)
The bigger inside factor has to be negative for these problems, because the third term is negative.
The sum of the middle term must give a negative value.

A square pool has a volume 4,086 cubic feet and depth 9 feet. A couple builds a fence 3.5 feet high around the pool. How many square feet of fencing surround the pool?
Answers
Answer:
Are they going to build the fence on the edge of the pool? How are they going to get into the pool? This question is illogical, however....
Step-by-step explanation:
A square pool is also wierd.
Volume Pool = side × side × depth
Volume Pool / depth = side² solve for side
side² = Volume Pool / depth
the fence is 3.5 feet tall
Fencing sqft one side = side × fence height for ONE side
Total Fencing = 4 × Fencing sqft one side
side² = 3464 ft³ / 8 ft
= 422 ft²
side = √422 ft²
= 20.54 ft
Fencing area one side = 20.54 × 3.5
= 71.899 ft²
Total fencing = 4× 71.899 ft²
= 287.6 ft² to the nearest tenth <-------------------- FINAL ANSWER

What is the area of a circle?If the considered circle has got is radius of 'r' units. Then, its area is calculated as:
[tex]A = \pi r^2 \: \rm unit^2[/tex]
where [tex]\pi = 3.14159...[/tex]
For this case, we are provided that:
Diameter of the circular dining table of Mrs. Smith = 3 feet
Thus, as radius is half of diameter, thus, radius of table = 3/2 = 1.5 feet
We find the area of the table since the area of the table pad that will be used for table will be equal to the area of the table because it will be applied all over the table.
The area of the table pad = area of the table = [tex]\pi (1.5)^2 \approx 3.14 \times (1.5)^2 = 7.065 \: \rm ft^2[/tex]
For each sq. foot, Mrs. Smith had to pay 50 cents = 0.5 dollars
Thus, for 7.065 sq. feet, the cost would be:
[tex]0.5 \times 7.065 = 3.5325[/tex] (in dollars)
Thus, the cost for the table pads that Mrs. Smith will have to pay for her circular dining room table is $3.5325 approx
