Answer: The slope is undefined
Step-by-step explanation:
Answer:
undefined
Step-by-step explanation:
slope equation is y2-y1/x2-x1
use points (-2,2) and (-2,-2)
insert values into equation: -2-2/-2+2
simplify: -4/0
if the zero is on top of the fraction, then the slope is zero but since the zero is on the bottom, the slope has to be undefined

C. on edge
Step-by-step
The graph that represents the function, based on the maximum and minimum values, and the period of the function, y = cos(4·x) is the option;
On a coordinate plane, a function has a maximum value at 1, and a minimum at negative 1. It completes one period at π/2. It crosses the x-axis at (0, 1)What is the period of a function?The period of a function is the length of the smallest interval over which the function repeats its values.
The function y = cos(4·x) has a maximum value of 1 and a minimum value of -1. '
The period of the function is; 2·π/|4| = π/2, which indicates that the function completes a cycle in an interval of π/2.
The function crosses the y-axis at x = 0, at which y = cos(4 × 0) = 1
The above information indicates that the graph that represents the function is the one that has a maximum of 1 and a minimum, of -1, completes a period at π/2, crosses the y-axis at (0, 1)
The correct option is therefore;
On a coordinate plane, a function has a maximum at 1, and minimum at negative 1. It completes one period at π/2. It crosses the y-axis at (0, 1)

The cost of a compact disc is $18. Mrs. Meridth bought 3 discs and received a 15% discount. If the sales tax is 8.8%, find the total price. Show each step.
Answers
Answer:
$49.572
Step-by-step explanation:
Given that :
Cost per disc = $18
Number of disc purchased = 3
Discount received = 15%
Sales tax = 8%
Original cost : cost per dic * number purchased
Original cost = $18 * 3 = $54
Discounted price = (100 - 15)% * $54
Discounted price = $45.9
Sales tax :
(100 + 8)% of $45.9
108% * $45.9
= $49.572
Total price = $49.572

Answer:
y = -3x + 3.
Step-by-step explanation:
The marked points on the line are (0, 3) and (1, 0) so:
the slope is (3 - 0) / (0 - 1) = -3.
The y-intercept is y = 3.
Therefore the equation of this line is y = -3x + 3.

I sell cookies for $3 and muffins for $7. Yesterday, I made $129. I sold a total of 27 items. How many of each did I sell? CAN SOMEONE ANSWER IT PLZ
Answers
9514 1404 393
Answer:
12 muffins15 cookiesStep-by-step explanation:
Often, you can work these problems in your head.
If you sold all cookies, your revenue would have been 27×3 = 81. It was 129-81 = 48 more than that. Each muffin generates 4 more revenue than a cookie dies, so there must have been 48/4 = 12 muffins. The 27-12 = 15 were cookies.
You sold 15 cookies and 12 muffins.
__
If you let a variable represent the most expensive item (m for muffins), then you can write an equation for the revenue. You may recognize that some of the steps in the solution match the "verbal" solution above.
3(27 -m) +7m = 129
4m +81 = 129
4m = 129 -81 = 48
m = 48/4 = 12 . . . muffins
27-12 = 15 . . . cookies

Part A: 16x^2 -56x+49
I'm not quite sure on Part B and C though, sorry :/.
Step-by-step explanation:
To find the expression we need to solve (4x-7)•(4x-7)
4x•4x = 16x^2
4x•-7= -28x
-7•4x= -28x
-7•-7=49
Combine alike terms

Write an equation of a parabola in standard form that has a vertex of (-3,-4) and passes through (1,4)
Answers
As we know vertex -
[tex]y=a(x+3)^2-4[/tex]
Passes through (1,4). Substitute x = 1 and y = 4
[tex]4=a(1+3)^2-4\\4=a(4)^2-4\\4=16a-4\\4+4=16a\\16a=8\\a=\frac{8}{16}\\a=\frac{1}{2}[/tex]
Therefore the vertex equation is [tex]y=\frac{1}{2}(x+3)^2-4[/tex]
Since you want the "standard" form then..
[tex]y=\frac{1}{2}(x^2+6x+1)\\y=\frac{1}{2}x^2+3x+\frac{1}{2}[/tex]
So the standard form is 1/2x^2 + 3x + 1/2
A really tough trivia quiz has 50 multiple-choice questions, each with four possibleanswers. Use a normal approximation to calculate the probability of randomly guessing the correct answers for at least half of the questions.
Answers
Answer:
0.00004
Step-by-step explanation:
Given that:
n = 50
Number of options = 4 ; 1 is the correct answer
Hence ;
p = 1/4 = 0.25
Using normal approximation :
Mean (m) = np = 50 * 0. 25 = 12.5
Standard deviation (s) = √(n*p*q)
q = 1 - p = 1 - 0. 25 = 0.75
s = √(50*0.25*0.75) = 3.062
At least half the question :
Half the question = 1/2 * 50 = 25
P(X ≥ 25) = P(X ≥ 24.5)
(x - m) / s
P(X ≥ 24.5) = (24.5 - 12.5) / 3.062
= 12 / 3.062
= 3.919
P(Z ≥ 3.919) = 0.00004 (Z probability calculator)
A number multiplied by 2 is no more than 12
X > 12
x < 12
2<_12
2x > 12

A rotating sprinkler that sprays water at a radius of 11 feet is used to water a lawn. Determine the area of the lawn that is being watered. Use 3.14 for pi. Round to the nearest tenth.
Answers
Answer:
69.1²feet
Step-by-step explanation:
area = pi x r²
11x2= 22
22x 3.14 = 69.08
69.1
The area of the lawn that is being watered is, 380.1 feet².
What is area of circle?The area of a circle is π multiplied by the square of the radius. The area of a circle, (A) when the radius 'r' is given is πr2. π is approximately 3.142
here, we have,
area = pi x r²
so,
11^2= 121
121x 3.14
= 380.1
Hence, The area of the lawn that is being watered is, 380.1 feet².

Step-by-step explanation:
To have a proportional relationship there must be a constant rate of change
6-5 / 9-7 = 1 /2
5-3 /7-4 = 2/3
these are different so this is not a proportional relationship
10-8 /150-120 =2/30
8-5 /120-75 =3/45
these are different so this is not a proportional relationship
10-8 /12-10 =2/2 =1
8-6 /10-8 =2/2= 1
These are the same therefore it is proportional
