Answer:
Undefined slope
Step-by-step explanation:
To calculate the slope between two points, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points.
The formula for the slope m between points (x₁, y₁) and (x₂, y₂) is: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex] , which is also known as "rise over run".
Here, we have the points (-9, 3) and (-9, 2).
x₁ = -9, y₁ = 3, x₂ = -9, y₂ = -2. We can plug these values in to the "rise over run" equation:
[tex]m=\frac{-2-3}{-9-(-9)}[/tex]
[tex]m=\frac{-5}{0}[/tex]
This is a vertical line.
The slope of a line cannot be undefined (a vertical line), because the x-coordinate never changes no matter what the y-coordinate is. Thus, the slope is undefined for the line passing between these two points.

How are the signs of the coordinates of point A and point C related HURRY
Answer: They both are located at (2,3)
Step-by-step explanation:
The sign that A and C are related is that they both have the same distance from the y axis.
What are coordinates?a pair of numbers that employ the horizontal and vertical distinctions from the two reference axes to represent a point's placement on a coordinate plane. typically expressed by the x-value and y-value pairs (x,y).
Coordinates are always written in the form of small brackets the first term will be x and the second term will be y.
For example (5,3) here 5 will be for the x and 3 will be for the y.
Another example is (9,0) here 9 is for x and 0 is for y.
Given that the coordinates A and C how are related now as we can see that both A and C are the same amount of distance by the y-axis.
This also can be seen by the coordination of A and C.

A radioactive substance decays according to the formula
Q(t)=Q0eâkt where Q(t) denotes the amount of the substance present at time t (measured in years),
Q0 denotes the amount of the substance present initially, and k (a positive constant) is the decay constant.
(a) Find the half-life of the substance in terms of k.
(b) Suppose a radioactive substance decays according to the formula
Q(t)=15eâ0.0001438t
How long will it take for the substance to decay to half the original amount? (Round your answer to the nearest whole number.) yr
Answer:
[tex]t=4820 y[/tex]
Step-by-step explanation:
a) The half-life equation is given by:
[tex]t_{1/2}=\frac{ln(2)}{k}[/tex]
b) Using the decay equation we have:
[tex]Q(t)=15e^{-0.0001438t}[/tex]
we need to find t when [tex]Q(t)=\frac{Q_{0}}{2}[/tex]
[tex]7.5=15e^{-0.0001438t}[/tex]
[tex]0.5=e^{-0.0001438t}[/tex]
[tex]ln(0.5)=-0.0001438t[/tex]
[tex]t=\frac{ln(0.5)}{-0.0001438}[/tex]
[tex]t=4820 y[/tex]
Therefore, it will take 4820 years to decay to half the original amount.

We randomly sample 50 items from Target stores and note the price for each. Then we visit Walmart and collect the price for each of those same 50 items. Should we use a paired or non-paired test?
Answer:
A paired t-test
Step-by-step explanation:
Number of items = 50
Variable in question = Price of each item
Classification of items = Similar or Same items
Locations from where items are drawn = 2 locations
The locations = Target Store & Walmart Store
Type of test to use = PAIRED TEST
This is because the items are same or similar and their comparison is the comparison of the mean values of two related groups. In this case, it is not immediately concluded that both groups have equal variance.

John goes out to eat at a local restaurant. The bill comes to $47.83. John want to leave a 20% tip. How much of a tip should he leave? (use only numbers) $____
Answer:
Twenty percent of $47.83 is equal to $14.66
If you did 20% of 47.83, that would equal 9.566. So, now you need to take the 5, which is equal to 500 cents, and turn it into 5 dollars. (One hundred cents is a dollar so 500 cents , is 5 dollars.) now it’s 9 + 5. Easy, it’s 14. Now add back the 66, and it’s 14.66 dollars. So the answer is...
14.66

Solve for X (PLEASE NEED NOW!!!!)
Answer:
Step-by-step explanation:
The two given angles add to 180 if the 2 angles that look parallel are parallel.
That means that
17x + 14 + 4x - 2 = 180 Combine like terms
21x + 12 = 180 Subtract 12
21x = 180 - 12 Combine
21x = 168 Divide by 21
x = 168 / 21
x = 8
Therefore 17x + 14 is the angle you want.
<B = 17*8 + 14 = 150.
===================
There's another way to do this.
4x - 2 + <B = 180
4*8 -2 +<B = 180
32 -2 + <B = 180
30 + <B = 180
<B = 180 - 30
<B = 150

1. Supposed that a ball is dropped from the upper observation deck of the Horizons 101 Tower 1., located
178 m above the ground. (a) What is the velocity of the ball after 5 sec? (b) How fast is the ball traveling
when it hits the ground?
Answer:
49m/s
59.07 m/s
Step-by-step explanation:
Given that :
Distance (s) = 178 m
Acceleration due to gravity (a) = g(downward) = 9.8m/s²
Velocity (V) after 5 seconds ;
The initial velocity (u) = 0
Using the relation :
v = u + at
Where ; t = Time = 5 seconds ; a = 9.8m/s²
v = 0 + 9.8(5)
v = 0 + 49
V = 49 m/s
Hence, velocity after 5 seconds = 49m/s
b) How fast is the ball traveling when it hits the ground?
V² = u² + 2as
Where s = height = 178m
V² = 0 + 2(9.8)(178)
V² = 0 + 3488.8
V² = 3488.8
V = √3488.8
V = 59.07 m/s
HELP NOW! A music club has 35 drum players. If 25% of the total number of members in the club are drum players, what is the total number of members in the club?
There's a way to think about it, in case you get other questions like this.
When you look at your problem, take out the 35. Out of the picture.
Look at 25%. 25% x 4 = 100% Meaning 4 is golden.
Then bring back the 35 and multiply it by 4. It gives you 140.
