Write the equation of the line that contains the points (5,7) and (5, -12):
Step-by-step explanation:
Well you first have to find the slope, which is y2-y1/x2-x1
Which is -12-7/5-5 and that equals to undefined.
So since you can't find the slope the answer should be undefined.

A parachutist's rate during a free fall reaches 225 kilometers per hour. What is this rate in meters per second? At this rate, how many meters will the parachutist fall during 15 seconds of free fall?
Answer:
62.5 m/s937.5 mStep-by-step explanation:
1 km/h = (1000 m)/(3600 s) = 1/3.6 m/s
Then
225 km/h = 225(1/3.6) m/s = 62.5 m/s
In 15 seconds, that's ...
(15 s)(62.5 m/s) = 937.5 m
Answer:
62.5
and
937.5

in 154 N38 what digit should be replaced to N to make the number divisible by 3,6 and 9?
Answer:
[tex]N = 6[/tex] so that number becomes divisible by 3, 6 and 9.
Step-by-step explanation:
In Number Theory there is a rule of thumb which states that sum of digits of a multiple of 3 equal 3 or a multiple of three. If we know that [tex]n = 154N38[/tex], then its sum of digits is:
[tex]x = 1 + 5+4+N+3+8[/tex]
[tex]x = 21+N[/tex] (Eq. 1)
We have to determine which digits corresponds to multiples of three, there are four digits:
N = 0
[tex]x = 21+0[/tex]
[tex]x = 21[/tex] ([tex]3\times 7 = 21[/tex])
N = 3
[tex]x = 21+3[/tex]
[tex]x = 24[/tex] ([tex]3\times 8 = 24[/tex])
N = 6
[tex]x = 21+6[/tex]
[tex]x = 27[/tex] ([tex]3\times 9 = 27[/tex])
N = 9
[tex]x = 21+9[/tex]
[tex]x = 30[/tex] ([tex]3\times 10 = 30[/tex])
We get the following four distinct options: 154038, 154338, 154638, 154938. Now we find which number is divisible by 6 and 9 by factor decomposition:
[tex]154038 = 2\times 3\times 25673[/tex]
[tex]154338 =2\times 3\times 29 \times 887[/tex]
[tex]154638 = 2\times 3\times 3\times 11\times 11\times 71[/tex]
[tex]154938 = 2\times 3\times 7\times 7\times 17\times 31[/tex]
It is quite evident that [tex]N = 6[/tex] so that number becomes divisible by 3, 6 and 9.

What is the image of point (0,2) after a rotation of 90° counterclockwise about the origin?
Answer:
(-2,0)
Step-by-step explanation:
remember the rule for 90 degree clockwise is (-y,x) opposite y and x
the negative in there DOES NOT mean it will always be negative it means opposite but in this case yes it's negative because the opposite of positive is negative
Hope this helps dude, I'm also learning this in online school lol. ^-^
The image of point (0,2) after a rotation of 90° counterclockwise about the origin is (-2, 0).
The given coordinate point is (0, 2).
What is rotation rule of 90°?Here are the rotation rules: 90° clockwise rotation: (x, y) becomes (y, -x) 90° counterclockwise rotation: (x, y) becomes (-y, x) 180° clockwise and counterclockwise rotation: (x, y) becomes (-x,-y).
The rule of 90° counterclockwise rotation: (x, y) becomes (-y, x), here
(-2, 0)
Therefore, the image of point (0,2) after a rotation of 90° counterclockwise about the origin is (-2, 0).

1. (12 points) The tennis team at Taft High School has 8 players, and the tennis team at McKinley High School has 7 players. Rebecca is on the team at Taft, and her sister Leah is on the team at McKinley. The two teams are going to play a tournament with 4 rounds. In each round, one player from Taft will play a match against one player from McKinley. Each player can play in at most one match. A schedule for the tournament consists of an ordered list of the names of the players from each school who will play in each of the four rounds. The schedule does not include the results of each match. (a) How many schedules are there? (b) How many schedules include neither sister? (c) How many schedules include both sisters and have them playing against each other? (d) How many schedules include both sisters, but have them playing in different matches?
Answer:
(a) 1,411,200.
(b) 302,400.
(c) 100,800.
(d) 1,008,000.
Step-by-step explanation:
Permutation is the number of ways to select k items from n distinct items in a specific order.
The formula to compute the permutation or arrangement of k items is:
[tex]^{n}P_{k}=\frac{n!}{(n-k)!}[/tex]
(a)
Compute the total number of schedules as follows:
[tex]\text{Total Number of Schedules}=\ ^{8}P_{4}\times \ ^{7}P_{4}[/tex]
[tex]=\frac{8!}{(8-4)!}\times \frac{7!}{(7-4)!}\\\\=\frac{8\times 7\times 6\times 5\times 4!}{4!}\times \frac{ 7\times 6\times 5\times 4\times 3!}{3!}\\\\=(8\times 7\times 6\times 5)\times (7\times 6\times 5\times 4)\\\\=1411200[/tex]
Thus, the total number of schedules are, 1,411,200.
(b)
Compute the number of schedules that includes neither sister as follows:
If neither of sister are included in the schedule then the number of players from the team are 7 and 6 respectively.
[tex]\text{Number of Schedules without the sisters}=\ ^{7}P_{4}\times \ ^{6}P_{4}[/tex]
[tex]=\frac{7!}{(7-4)!}\times \frac{6!}{(6-4)!}\\\\=\frac{ 7\times 6\times 5\times 4\times 3!}{3!}\times \frac{ 6\times 5\times 4\times 3\times 2!}{2!}\\\\=(7\times 6\times 5\times 4)\times (6\times 5\times 4\times 3)\\\\=302400[/tex]
Thus, the number of schedules that includes neither sister is 302,400.
(c)
Compute the number of schedules including both sisters and have them playing against each other as follows:
If both the sisters are playing against each other then there will be three more places to be filled in both the teams.
And the two sisters can play in any of the 4 matches.
[tex]\text{number of schedules including} \\\text{both sisters against each other}=(\ ^{7}P_{3}\times \ ^{6}P_{3})\times 4[/tex]
[tex]=[\frac{7!}{(7-3)!}\times \frac{6!}{(6-3)!}]\times 4\\\\=[\frac{ 7\times 6\times 5\times 4!}{4!}\times \frac{ 6\times 5\times 4\times 3!}{3!}]\times 4\\\\=[(7\times 6\times 5)\times (6\times 5\times 4)]\times 4\\\\=100800[/tex]
Thus, the number of schedules including both sisters and have them playing against each other is 100,800.
(d)
Compute the number of schedules including both sisters as follows:
[tex]\# \text {Schedules with the Sisters}=\text{Total}\ \#\ \text{Schedules }-\ \# \text {Schedules without the Sisters}[/tex] [tex]=1411200-302400\\=1108800[/tex]
Now compute the number of schedules having the sisters playing in different matches as follows:
[tex]\text{Playing in Different Matches}=\# \text {Schedules with the Sisters}-\text{Playing together}[/tex]
[tex]=1108800-100800\\=1008000[/tex]
Thus, the number of schedules including both sisters, but have them playing in different matches is 1,008,000.

what's the answer? pls help
Answer:
The slope of the line is 1.
Step-by-step explanation:
To solve this problem, we should use the equation for slope, which is given below:
slope = m = (y2-y1)/(x2-x1)
We can now plug in two points that are given in the table.
slope = m = (9-5)/(9-5)
We can simplify our expression for slope by first computing the subtraction inside the parentheses.
slope = m = 4/4
If we simplify the expression further by dividing the numerator by the denominator, we get:
slope = m = 1
Therefore, the correct answer is slope = 1.

Answer:
Step-by-step explanation:
If the sum of the two given angles is 5 + 10 = 15 then the third side cannot be larger than 15. If it is, the two given angles will fall flat on the third angle.
If the third angle is less than 5 then the sum will be less than 10 and the same thing will happen as described above.

Answer:
13
Step-by-step explanation:
Answer: 13
Step-by-step explanation:
The distance formula between two points is:
[tex]c = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]
Our points are as follows -
[tex]x_2 = 0, x_1 = 5\\y_2 = 8, y_1 = -4[/tex]
If we plug them in:
[tex]c = \sqrt{(0 - 5)^2 + (8 - (-4))^2}[/tex]
All we need to do now is simplify
[tex]c = \sqrt{(-5)^2 + (12)^2}[/tex]
[tex]c = \sqrt{25 + 144}[/tex]
[tex]c = \sqrt{169} = 13[/tex]

Which of the following graphs represents the equation y=2x−3?
Answer:
D. (the one in the right hand bottom corner)
Answer:
Bottom right
Step-by-step explanation:
The equation is y = 2x - 3
2 represents the slope
-3 represents the y-intercept
The y-intercept is when x = 0
So first, we look at the graphs and find the graphs that display when x = 0, y = -3 aka (0, -3)
From this, we can deduce the two graphs on the left side are wrong
It must be the two on the right
Now we figure out which one has a slope of 2 aka rise over run = 2/1
Which graph goes up (rises) 2 units and goes forward (runs) 1 unit?
The top right graph depicts a slope of 1/2, not 2/1 so this is incorrect
The bottom right graph displays a slope of 2/1 aka 2
Bottom right graph is the correct answer

Answer: C
Step-by-step explanation: First you have to do y-y÷x-x. So first you do 2-3 which gives you -1. Then you do 6-4 which gives you 2. Then you divide -1÷2 which gives you -0.5x. Now you know it's either C or D because it's negative. For the y-intercept, you have to plug in one of the ordered pairs to y and x using the slope-intercept form.
