The value of F(8) is 26.
What is function?In mathematics, a function is represented as a rule that produces a distinct result for each input x. In mathematics, a function is indicated by a mapping or transformation. Typically, these functions are identified by letters like f, g, and h. The collection of all the values that the function may input while it is defined is known as the domain. The entire set of values that the function's output can produce is referred to as the range. The collection of values that could result in a function's outputs is known as the co-domain.
Given:
F (x) =3x+2
Now, F(8)= 3x+2
=3(8) +2
=24 +2
=26
Hence, the value of F(8) is 26.

A copy machine makes 126 copies in 3 minutes and 30 seconds. How many copies does it make per minute?
Answer: 36 copies per minute
Step-by-step explanation:
126 copies in 3.5 minutes
We want x number of copies per 1 minute
[tex]\frac{126copies}{3.5minutes} = \frac{xcopies}{1minute}[/tex]
Cross multiply and we get
126 = 3.5x
Solve for x.
x = 126/3.5

Anya has 115 mangoes lauren has five times the the number of mangoes Anya has they put them together and sold them in the market at $450 to $15 the sold all the mangoes how much money was collected at the end of the sale
The total amount of money collected if Anya and Lauren sold their mangoes at $15 is $10,350
How to find total revenue made from selling the mangoes?Number of mangoes Anya has = 115 mangoesNumber of mangoes Lauren has = 5 × 115= 575 mangoes
Total number of mangoes = Number of mangoes Anya has + Number of mangoes Lauren has
= 115 + 575
= 690 mangoes
Amount each mangoes was sold = $15
Total amount of money collected = Total number of mangoes × Amount each mangoes was sold
= 690 × 15
= $10,350
So therefore, Anya and Lauren sold their total mangoes for $10,350

The 20% off sale is a better deal than the $200 rebate or
$150 coupon for the $1,500 dining set. The Porters
budgeted $1,250 for a new dining room set. Explain why
this is the best deal for them. Are they under budget?
Answer:
20% off is better and it is the only offer which is under the budget.
20% off of the $1,500 dining set is $300, and the dining set price will be 1500 - 300 = $1200.
And by applying the $150 coupon, the dining set price will be $1500 - $150 = $1350.
Therefore 20% off is better and it is the only offer which is under the budget.

If f(x)= x2-5 and g(x)= -3x + 2, find f(g(x))
Answer:
D. 9x² - 12x - 1
Explanation:
To find f(g(x)), we need to replace x by g(x) as follows:
f(x) = x² - 5
f(g(x)) = (g(x))² - 5
Then, g(x) is equal to -3x + 2, so replacing g(x) by (-3x + 2), we get:
f(g(x)) = (g(x))² - 5
f(g(x)) = (-3x + 2)² - 5
f(g(x)) = (-3x)² + 2(-3x)(2) + 2² - 5
f(g(x)) = 9x² - 12x + 4 - 5
f(g(x)) = 9x² - 12x - 1
Therefore, the answer is D. 9x² - 12x - 1

What is an ellipse?In mathematics, an ellipse is a planar curve with two focal points, where the total of the two distances from any point on the curve to the focal points is a constant. It generalizes the shape of a circle, a unique variety of ellipse in which the two focus points coincide. For an ellipse with its center at (0,0) and its axes parallel to the coordinate axes, one point can be used to infer three more points. The other three points are (a,b), (a,b), and (a,b) if your point is (a,b).So, the foci of the ellipse are:

Use the digits 1-9 to create 3 equivalent ratios. Each digit can only be used once. _:_=_ _:_=_ _:_ _
Equivalent ratios are the ratios that are the same when we compare them. Three equivalent ratios are 1/2, 4/8, 3/6 in digits from 1 to 9.
What is Ratio?A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0. A proportion is an equation in which two ratios are set equal to each other
Equivalent ratios are the ratios that are the same when we compare them.
The digits from 1 to 9 include 1,2,3,4,5,6,7,8,9.
Ratios are nothing but fractions.
Let 1/2 (one by two) is the first ratio.
Now 3/6 (three by six) is the second ratio
4/8 (four by eight) is the third ratio.
If we calculate the value of 1/2 = 0.5
The value of 3/6=1/2=0.5
The value of 4/8= 1/2=0.5
we get the same answer for all the ratios 1/2, 4/8 and 3/6 that is 0.5
That is 0.5 or 1/2.
Hence the three equivalent ratios are 1/2, 4/8, 3/6.

Given the equation of a parabola:
[tex]5x^2-50x-4y+113=0[/tex]• You can rewrite it in Standard Form by following these steps:
1. Add the y-term to both sides of the equation:
[tex]\begin{gathered} 5x^2-50x-4y+113+(4y)=0+(4y) \\ \\ 5x^2-50x+113=4y \end{gathered}[/tex]2. Subtract the Constant Term from both sides of the equation:
[tex]\begin{gathered} 5x^2-50x+113-(113)=4y-(113) \\ \\ 5x^2-50x=4y-113 \end{gathered}[/tex]3. Divide both sides of the equation by 5 (the leading coefficient)
[tex]x^2-10x=\frac{4}{5}y-\frac{113}{5}[/tex]4. The coefficient of the x-term is:
[tex]b=-10[/tex]Then, you need to add this value to both sides:
[tex](\frac{-10}{2})^2=5^2[/tex]Therefore.
[tex]\begin{gathered} x^2-10x+5^2=\frac{4}{5}y-\frac{113}{5}+5^2 \\ \\ x^2-10x+5^2=\frac{4}{5}y+\frac{12}{5} \end{gathered}[/tex]5. Rewrite the equation as follows:
[tex]\begin{gathered} (x-5)^2=\frac{4}{5}(y+3) \\ \\ (x-5)^2=0.8(y+3) \end{gathered}[/tex]• Having the equation written in Standard Form:
[tex](x-h)^2=4p(y-k)[/tex]You can identify that:
[tex]4p=\frac{4}{5}[/tex]Solving for "p", you get:
[tex]p=\frac{4}{5\cdot4}=\frac{1}{5}=0.2[/tex]• You can identify that:
[tex]\begin{gathered} h=5 \\ k=-3 \end{gathered}[/tex]Therefore, the Vertex is:
[tex](5,-3)[/tex]• By definition, the Focus of a parabola that opens upward is given by:
[tex](h,k+p)[/tex]Then, in this case, this is:
[tex](5,-3+0.2)=(5,-2.8)[/tex]• By definition, the Directrix for a parabola that opens upward is given by:
[tex]y=k-p[/tex]Then, in this case, you get:
[tex]\begin{gathered} y=-3-0.2 \\ \\ y=-3.2 \end{gathered}[/tex]Hence, the answers are:
• Standard Form:
[tex](x-5)^2=0.8(y+3)[/tex]• Value for "p":
