what is the end behavior of the function?
The end behavior of the function f(x) describes the behavior of the function as x approaches the +∞ f(x) approaches to 1/2 and the x approaches the -∞ f(x) approaches to 1/2.
What is a function?It is defined as a special type of relationship and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
[tex]\rm f(x) = \dfrac{4x-7}{8x+8}[/tex]
For the end behavior:
As x → ∞ f(x) → 1/2
And x → -∞ f(x) → 1/2
Thus, the end behavior of the function f(x) describes the behavior of the function as x approaches the +∞ f(x) approaches to 1/2 and the x approaches the -∞ f(x) approaches to 1/2.

The value that can take the place of "?" is -6a. The length of line AB is 6a units.
What is the length of any line on the graph?The distance or length of any line on the graph,
[tex]d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
where,
d = distance/length of the line between point 1 and 2,
(x₁ , y₁) = coordinate of point 1,
(x₂ , y₂) = coordinate of point 2,
The length of a line with two points known is written as,
[tex]d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Given the coordinate of points A and B are (-3a,b) and (-3a,b), respectively. Therefore, the length of the line AB can be written as,
[tex]AB = \sqrt{(-3a-3a)^2+(b-b)^2}\\\\AB = \sqrt{(-6a)^2+(0)^2}\\\\AB = 6a[/tex]

15) A, B, C, D, E and F are towns situated as follows. * A is 30 km east of D * C is 20 km east of E * F is 10 km west of B * D is 10 km south of F * A is 10 km north of C How far would you need to travel to get from B to E?
Answer:
Option D: 20km South
Step-by-step explanation:
Lets say A = (0, 0)
Finding B:A is 30km East of D which makes D = (-30, 0)
D is 10km South of F which makes F = (-30, 10)
F is 10km West of B which makes B = (-20, 10)
Finding E:A is 10km North of C which makes C = (0, -10)
C is 20km East of E which makes E = (-20, -10)
Finding the answer:Find distance from B = (-20, 10) to E = (-20, -10)
1. Cancel equivalent values:
x of B = (-20) and x of E = (-20)
Remove x from equation.
2. Solve for answer:
B = 10 and E = (-10)
Find the difference: (-10) - 10 = (-20)

Optimize the equation P = 3x + y using the constraints
x ≥ 0, x ≤ 4, y ≥-1 and y ≤ 5.
What is the maximum?
Answer:
P = 17
Step-by-step explanation:
let's separate this into x and y components
x component: 3x
as x increases, so does the x component. e.g. 0 * 3 = 0, 4 * 3 = 12. therefore, we want x as high as possible
y component: y
as y increases, so does the y component. this is because the y component is literally just y.
therefore, given these two, to maximize P, we want x and y to be as high as possible
in 0 ≤ x ≤ 4, the maximum of x is 4
in -1 ≤ y ≤ 5, the maximum of y is 5
plug these in to get
3(4) + 5 = 17 as our answer

The money she started with is 100 * 1.40/35 which is $4.
Answer:

To compare the monthly grocery expense based on family size, the results are split into two categories:
Families with up to 2 children.
Families with 3 or more children.
The box plots for each category are shown.

Which statement is BEST supported by the box plots?
A
The grocery expense for the category of "0-2 Children" is more spread out than the other category. This is most likely due to the median being much lower for the "0-2 Children" category than for the other category.
B
The grocery expense for the category of "3 or More Children" is more spread out than the other category. This is most likely due to families in the "0-2 Children" category having more outlier results.
C
The grocery expense for the category of "0-2 Children" is more spread out than the other category. This is most likely due to the minimum and maximum being closer together in the "0-2 Children" category.
D
The grocery expense for the category of "3 or More Children" is more spread out than the other category. This is most likely due to families in the "3 or More Children category" having more outlier results.
The statement supported by the box plot is D. The grocery expense for the category of "3 or more children" is more spread out than the other category.

find the surface area 10.2 mi 14 mi
Answer:
The surface area = 320.442450666159 mi²Step-by-step explanation:
Formula : ( surface area of a cone )_________________________
The total surface area = The curved surface area + area of the base
____________________________________________________
→The curved surface area = π × r × g = π × r × (√(h2 + r2))
where g is the slant height of the cone and r is the radius of the base
and h is the height of the cone
and g = √(h2 + r2)
→Area of the base = π × r²
We get :
The curved surface area = π × r × (√(h2 + r2))
= π × 5.1 × √(14^2+(5.1)^2)
= 238.729625746288
Area of the base = π × r²
= π × (5.1)^2
= 81.712824919871
Conclusion:
The total surface area = The curved surface area + area of the base
= 238.729625746288 + 81.712824919871
= 320.442450666159
