Which of the following best describes the slope of the line below?
A. Zero
B. Undefined
C. Positive
D. Negative
Answer:
Undefined
Step-by-step explanation:
It is undefined because the x value equals multiple y values so the slope is undefined :)
Have a great day!!
Please rate and mark brainliest!!
Answer: Choice B
Undefined
Reason:
Vertical lines always have undefined slopes.
This is because slope = rise/run, but run = 0 for vertical lines. The "run" describes how much the line moves to the right, but such a thing doesn't happen since it's stuck on one x value only.
So we could have something like slope = rise/run = 1/0 = undefined. Dividing over zero is not allowed.

16. A can in the shape of a cylinder has a diameter of 6 centimeters
and a height of 10 centimeters, which measurement is closest to
the total surface area of the can in square centimeters?
Answer:
surface area = 245.04 cm² (nearest tenth)
Step-by-step explanation:
Surface area of a closed cylinder = [tex]2\pi r^2+2\pi rh[/tex]
Given:
diameter = 6 cm ⇒ radius = 3 cmheight = 10 cm⇒ surface area = 2 × [tex]\pi[/tex] × 3² + 2 × [tex]\pi[/tex] × 3 × 10
= 78[tex]\pi[/tex]
= 245.04 cm² (nearest tenth)
Chris drove his car to the movie theater. The graph below represents Chris's speed over time, from when he left his house to when he arrived at the theater. At which times did Chris most likely stop at a stoplight? A. time = 3 min, time = 10.5 min, time = 12 min B. time = 2 min, time = 11 min C. time = 0 min, time = 21 min D. time = 1.5 min, time = 6 min, time = 14 min
Answer:
B
Step-by-step explanation:
Stopping at a stoplight means that Chris's speed would be zero on the graph. The times that his speed is zero are times t = 0, t = 2 min, t = 11 min, and t = 21 min. Because the graph shows his speed from the time he left his house (at t = 0) to the time he arrived at the theater (at t = 21 min), the most likely times he stopped at stoplights are times t = 2 min and t = 11 min.

A ship leaves port at noon and has a bearing of S29oW. The ship sails at 20 knots. How many nautical miles south and how many nautical miles west will the ship have traveled by 6:00 PM
Answer:
Approximately [tex]58.2\; \text{nautical miles}[/tex] (assuming that the bearing is [tex]{\rm S$29^{\circ}$W}[/tex].)
Step-by-step explanation:
Let [tex]v[/tex] denote the speed of the ship, and let [tex]t[/tex] denote the duration of the trip. The magnitude of the displacement of this ship would be [tex]v\, t[/tex].
Refer to the diagram attached. The direction [tex]{\rm S$29^{\circ}$W}[/tex] means [tex]29^{\circ}[/tex] west of south. Thus, start with the south direction and turn towards west (clockwise) by [tex]29^{\circ}[/tex] to find the direction of the displacement of the ship.
The hypothenuse of the right triangle in this diagram represents the displacement of the ship, with a length of [tex]v\, t[/tex]. The dashed horizontal line segment represents the distance that the ship has travelled to the west (which this question is asking for.) The angle opposite to that line segment is exactly [tex]29^{\circ}[/tex].
Since the hypotenuse is of length [tex]v\, t[/tex], the dashed line segment opposite to the [tex]\theta = 29^{\circ}[/tex] vertex would have a length of:
[tex]\begin{aligned}& \text{opposite (to $\theta$)} \\ =\; & \text{hypotenuse} \times \frac{\text{opposite (to $\theta$)}}{\text{hypotenuse}} \\ =\; & \text{hypotenuse} \times \sin (\theta) \\ =\; & v\, t \, \sin(\theta) \\ =\; & v\, t\, \sin(29^{\circ})\end{aligned}[/tex].
Substitute in [tex]\begin{aligned} v &= 20\; \frac{\text{nautical mile}}{\text{hour}}\end{aligned}[/tex] and [tex]t = 6\; \text{hour}[/tex]:
[tex]\begin{aligned} & v\, t\, \sin(29^{\circ}) \\ =\; & 20\; \frac{\text{nautical mile}}{\text{hour}} \times 6\; \text{hour} \times \sin(29^{\circ}) \\ \approx\; & 58.2\; \text{nautical mile}\end{aligned}[/tex].
The total cost of Anja’s trip to the dentist was $628.35. She paid a flat fee of $89.95 which included the checkup and cleaning and then had 4 cavities filled, each of which cost the same amount. Which shows the correct equation and value of x, the cost of each cavity filling?
a 4 x + 89.95 = 628.35; x = 134 dollars and 60 cents
b 4 (89.95) + x = 628.35; x = 268 dollars and 55 cents
c 4 x + 89.95 = 628.35; x = 179 dollars and 58 cents
d 4 (89.95) + x = 628.35; x = 538 dollars and 40 cents
|| ▼ Answer ▼ ||
Option (A) 4 x + 89.95 = 628.35; x = 134 dollars and 60 cents
|| ✪ Solution ✪ ||
Total cost of the trip was $628.35, Anja paid $89.95 as a flat fee, and paid extra for the four tooth fillings, the equation that represents this situation is:
[tex]4x+89.95=628.35-- > (1)[/tex]
The solution to equation (1) is as follows:
[tex]4x=628.35-89.95=538.4[/tex]
[tex]x=\frac{538.4}{4} =134.6[/tex]
[tex]x=134.6[/tex]
x = $134 and 60 cents
Conclusion: The answer is Option (a).

Adam and 3 riends go on holiday together for a week .The costs of the holiday will be shared equally between 4 friends .These are the cost: £1460 for 4 return plane tickets £720 for the accomidation £180 for the car hire for a week . How does adam have to pay for his share of the cost
Answer:
Adam's share is £590
Step-by-step explanation:
Given
Return Ticket = £1460
Accommodation = £720
Car Hire = £180
Required
Determine Adam's share
First, we need to determine the total cost.
Total = Return Ticket + Accommodation + Car Hire
Total = £1460 + £720 + £180
Total = £2360
Next, is to determine the average.
[tex]Average = Total/4[/tex]
[tex]Average = 2360/4[/tex]
[tex]Average = 590[/tex]
Hence;
Adam's share is £590

from $825 to 875. Who had the larger percent increase in their rent? Remember to set up your ratios using
the original rent. See Exercise #1 from the lesson if you want to see a similar problem.
Pls send the equation
Answer:
Imani's rent had a higher percent increase
Step-by-step explanation:
A change from 560 to 600 represents a positive change (increase) of 7.1428571429%
A change from 825 to 875 represents a positive change (increase) of 6.0606060606%
Percent change = New - Old /825 × 100

Select the correct answer. Given that a function, g, has a domain of -20 ≤ x ≤ 5 and a range of -5 ≤ g(x) ≤ 45 and that g(0) = -2 and g(-9) = 6, select the statement that could be true for g. A. g(7) = -1 B. g(0) = 2 C. g(-4) = -11 D. g(-13) = 20
Answer:
The correct option is;
D. g(-13) = 20
Step-by-step explanation:
The given information are;
The domain of the function, g is given as -20 ≤ x ≤ 5
The range of the function, g(x), is given as -5 ≤ g(x) ≤ 45
g(0) =-2 and g(-9) = 6
Therefore, given that the function increases from -2, to 6 as the input variable decreases from 0 to -9
Therefore, if the variable, x, decrease further, to -13, the function will likely increase further, to about 20, while in the variable, x, increases further, to 7, the function may likely decrease to about -1
Therefore, we can get either;
g(-13) = 20 or g(7) = -1
However, the domain of the function is -20 ≤ x ≤ 5, therefore, 7 is outside the domain, giving g(-13) = 20 as the only statement that could be true

Answer: to find the answer you need to
Step-by-step explanation:
Create a table with headings n and an where n denotes the set of consecutive positive integers, and an represents the term corresponding to the positive integers. You may pick only the first five terms of the sequence. For example, tabulate the series 5, 10, 15, 20, 25, . . .
Solve the first common difference of a. Consider the solution as a tree diagram. There are two conditions for this step. This process applies only to sequences whose nature are either linear or quadratic.Condition 1: If the first common difference is a constant, use the linear equation ax + b = 0 in finding the general term of the sequence.

(100 points, Need help with this ASAP) I bought a used grain silo. I am going to use it as a groom's room at our venue. I am going to paint the inside of it to brighten it up a little. I need to decide how many cans of paint to buy. The silo is 15' across and 10' tall to the top of the cylindrical part. The top of the silo looks like a funnel. It is also 15' across. It is 4' tall. The ceiling is the funnel top. A can of paint covers approximately 400 sq ft. How many cans of paint will I need to buy?
Answer:
2 cans of paint
Step-by-step explanation:
Surface area of an open cylinder = [tex]2\pi rh[/tex]
(where r is the radius and h is the height)
⇒ SA = 2 × [tex]\pi[/tex] × (15 ÷ 2) × 10 = 150[tex]\pi[/tex] ft²
Surface area of an open cone = [tex]\pi r\sqrt{h^2+r^2}[/tex]
(where r is the radius and h is the height)
⇒ SA = [tex]\pi[/tex] × (15 ÷ 2) × √(4² + 7.5²) = 63.75[tex]\pi[/tex] ft²
Total surface area = 150[tex]\pi[/tex] + 63.75[tex]\pi[/tex] = 213.75[tex]\pi[/tex] = 671.52 ft² (nearest hundredth)
If one can of paint covers approx. 400 ft² then 2 cans of paint needed to cover 671.52 ft²
