Which representation does not show a proportional relationship between x and y?
Answer:
Table A
Step-by-step explanation:
looking at the two tables, we have the observations as follows;
For table B, if we divide x by y; we have a ratio of 2/3
This happens throughout the table
What this means is that x = 2/3 * y
But for table A, we notice a pattern for the first two lines
The pattern here is that x = 2y
But as we move to the next two rows, we notice this fails and thus, we fail to establish a pattern that works for all the rows;
Hence table B has a pattern for all its rows

Final answers:
Vertex: (1,9)Domain: all real numbers, or (-infinity, infinity)Range: (-infinity, 9]Maximum: 9; there is no minimumy-intercept: (0,8)Interval of increase: (-infinity, 1)Interval of decrease: (1, infinity)Average rate of change: 3 or -3Explanations
Vertex: this is the maximum or minimum point on the graph, which is (1,9).Domain: this is everywhere that the function is defined. Since there are no values of x for which -x^2 + 2x + 8 is not defined, the domain is all real numbers, or [tex](-\infty, \infty)[/tex].Range: this is all y-values the function takes. We can see from the graph that the function takes on all values less than or equal to 9, so the range is (-infinity, 9].Maximum or minimum: the maximum value is 9. There is no minimum value.y-intercept: this is the point where the graph intersects the y-axis, which is (0,8) or simply 8. You can think of this as the value of f(x) when x is zero.Interval of increase: f(x) is increasing on (-infinity, 1).Interval of decrease: f(x) is decreasing on (1, infinity).Average rate of change: the question is asking us to find the slope between the vertex and one of the x-intercepts – I will use (-2,0). The vertex is (1,9). The average rate of change is the slope between these points, which is (9-0)/(1-(-2)), or 3. If you instead used the x-intercept of (4,0), you would get an answer of -3.Ask questions help!!!!!

A cone has a slant height that measures 24 feet and a radius that measures 13.5 feet. What is the surface area of the cone?
Surface area of the cone is 1589.625 feet²
What is cone?A cone is a three-dimensional geometric shape that tapers smoothly from a flat base to a point called an apex or vertex. A cone is formed by a series of line segments, half-lines, or lines connecting apex that is common to all points on the base that lie in a plane that does not contain the apex.
Given,
Slant height of the cone l = 24 feet
Radius of the cone r = 13.5 feet
Surface area of cone
= πr² + πrl
= 3.14(13.5)² + 3.14×13.5×24
= 3.14(182.25) + 3.14(324)
= 572.265 + 1017.36
= 1589.625 feet²
Hence, 1589.625 feet² is the surface area of the cone.

m∠C to the nearest degree is 10 degrees.
Step-by-step explanation:

3) Michael is getting dinner for his drama club on the evening of their final rehearsal.
The budget for dinner is $60
Michael plans to buy some prepared dishes from a supermarket. The prepared dishes are sold
by the pound, at $5.50 a pound
He also plans to buy two large bottles of sparkling water at $2.50 each
a) Write an inequality that represents the situation. (let p = weight of prepared dishes in pounds) 2
points
b) How many pounds of prepared dishes can Michael buy? Explain or show your reasoning, 3 points
Answer:
5.5p + 5 ≤ 60
10 pounds
Step-by-step explanation:
a) The maximum total cost he can spend is $60.
5.5 * p + 2 * 2.5 ≤ 60
Simplify.
5.5p + 5 ≤ 60
b) Solve 5.5p + 5 ≤ 60
Subtract 5 from both sides
5.5p ≤ 55
Divide both sides by 5.5
p ≤ 10
So, the maximum he can buy is 10 pounds of food

What two numbers multiply to -40 and add to 10
Answer:
5 + sqrt(65), 5 - sqrt(65)
Step-by-step explanation:
x + y = 10
x×y = -40
so, two equations with 2 variables. using one equation to express one variable by the second. and then using the second equation to solve and calculate the second variable. and then by knowing the second variable we calculate the first.
=> x = 10 - y
=> (10-y)×y = -40
=> -1×(10-y)×y = 40
=> (y-10)×y = 40
=> y^2 - 10×y - 40 = 0
remember the solution for a quadratic equation
a×x^2 + b×x + c
is
x = (-b ± sqrt(b^2 - 4×a×c)/(2×a)
in our case
a = 1
b = -10
c = -40
and we used "y".
so,
y = (--10 ± sqrt((-10)^2 - 4×1×(-40))/(2×1) =
= (10 ± sqrt(100 + 160))/2 = (10 ± sqrt(260))/2 =
= (10 ± sqrt (4×65))/2 = 10/2 ± 2×sqrt(65)/2 =
= 5 ± sqrt(65)
=>
for y = 5 + sqrt(65), x = 10 - 5 - sqrt(65) = 5 - sqrt(65)
for y = 5 - sqrt(65), x = 10 - 5 + sqrt(65) = 5 + sqrt(65)

Consider the sequence 3/4, 4/5, 5/6, 6/7, . . .
Which statement describes the sequence?
A. The sequence diverges.
B. The sequence converges to 0.
C. The sequence converges to ∞.
D. The sequence converges to –∞.
Answer:
b is a correct answer
Step-by-step explanation:
that is correct and right answer.
The sequence 3/4, 4/5, 5/6, 6/7, . . . is diverges option (A) The sequence diverges is correct.
What is the convergent of a series?
A series is convergent if the series of its partial sums approaches a limit; that really is, when the values are added one after the other in the order defined by the numbers, the partial sums get closer and closer to a certain number.
The sequence can be defined as the systematic way of representing the data that follows a certain rule of arithmetic.
It is given that:
The sequence:
3/4, 4/5, 5/6, 6/7, . . .
AS we know, the convergent sequence occurs when, as n approaches infinity, you arrive at a final and constant term through a number of terms.
Divergent sequences are those in which the terms never stabilize; instead, they constantly increase or decrease as n approaches infinity, approaching either infinity or -infinity.
The nth term of the sequence
a(n) = 2+n/3+n
Applying divergence test:
The sequence diverges
Thus, the sequence 3/4, 4/5, 5/6, 6/7, . . . is diverges option (A) The sequence diverges is correct.

Height of quadrilateral = 8 m
Length of perpendicular on diagonal = 2 m
Find:
Area of quadrilateral
Computation:
We know that, Diagonal divides quadrilateral into two equal triangle
So,
Area of quadrilateral = 2[Area of triangle]
Area of quadrilateral = 2[(1/2)(b)(h)]
Area of quadrilateral = 2[(1/2)(8)(2)]
Area of quadrilateral = 2[(4)(2)]
Area of quadrilateral = 2[8]
Area of quadrilateral = 16 m²
