The endpoints of CD are C(1,-6) and D(7,4). Find the coordinates of the midpoint M.
Answers
Answer:
(4, -1)
Step-by-step explanation:
Given:
C(1, -6)
D(7, 4)
Required:
Midpoint of CD using [tex] M(\frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2}) [/tex]
SOLUTION:
[tex] M(\frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2}) [/tex]
Let [tex] C(1, -6) = (x_1, y_1) [/tex]
[tex] D(7, 4) = (x_2, y_2) [/tex]
Thus:
[tex] M(\frac{1 + 7}{2}, \frac{-6 + 4}{2}) [/tex]
[tex] M(\frac{8}{2}, \frac{-2}{2}) [/tex]
[tex] M(4, -1) [/tex]

The function f is defined by f(x)= - 1/2x^2
Write down the expression for h(x).
Answers
Answer: -1/2 (x-4)^2 + 3
Step-by-step explanation:
Since the graphs both have the same stretch of -1/2x^2, you just need to see how much they were shifted up, down, left, or right. h(x) is shifted up 3 and right 4 of f(x) so h(x) = -1/2 (x-4)^2 + 3
Answer:
[tex]h(x)=-\dfrac12(x-4)^2+3[/tex]
Step-by-step explanation:
Given:
[tex]f(x)= - \dfrac12x^2[/tex]
From inspection of the graph, [tex]f(x)[/tex] has been translated 4 units to the right and 3 units up.
Therefore, [tex]h(x)=f(x-4)+3[/tex]
[tex]\implies h(x)=-\dfrac12(x-4)^2+3[/tex]

It takes 8 minutes to cut a board twice. How long does it take to cut the board into 9 pieces
Answers
Answer:
36 minutes
Step-by-step explanation:
With the data given, we can calculate that if it takes 8 minutes to cut a board twice then, it takes four minutes to cut one board. We can then determine how long it takes the cut a board into 9 pieces by multiplying 9 x 4 to equal the amount that it takes for a board to be cut into 9 pieces which would be 36.
In conclusion, it would take 36 minutes to cut a board into 9 pieces.

Mitchell has been given the option of either paying his $200 bill now or settling it for $204 after 1 month (30 days). If he chooses to pay after 1 month, find the simple interest rate at which he would be charged.
Answers
The simple interest rate that he would be of 24.33% a year.
Simple InterestSimple interest is used when there is a single compounding per time period.
The amount of money after t years in is modeled by:
[tex]A(t) = A(0)(1 + rt)[/tex]
In which:
A(0) is the initial amount.r is the interest rate, as a decimal.In this problem, considering than an year has 365 days, the parameters are as follows:
[tex]A(t) = 204, A(0) = 200, t = \frac{30}{365}[/tex]
Hence:
[tex]A(t) = A(0)(1 + rt)[/tex]
[tex]204 = 200\left(1 + \frac{30}{365}r\right)[/tex]
[tex]1 + \frac{30}{365}r = \frac{204}{200}[/tex]
[tex]\frac{30}{365}r = 0.02[/tex]
[tex]r = \frac{365}{30} \times 0.02[/tex]
[tex]r = 0.2433[/tex]

If x = 7-p and y = 3p + 4, which of the following
expresses y in terms of x ?
step by step please !!
Answers
Answer:
Step-by-step explanation:
Answer:
y = -3x + 25
Step-by-step explanation:
You have to find p first.
You can do this by using the x equation and moving the p to the right by adding p to each side to get p + x = 7.
Now, move the x to the left by subtracting x on both sides to get a final answer of p = 7 - x
Then, you can substitute p into the y equation.
So, y = 3(7 - x) + 4.
Distribute to get y = 21 - 3x + 4
Combine like factors to get y = -3x + 25

Give your answer using the 24 hour clock.
Answers
Answer:
19:37
Step-by-step explanation:
1 h and 54 m of the movie + 13 minutes that he paused is 2h and 7 m and adding that to the time it was makes it 19:37 or 7:37 pm
The time when the movie finished is 19:37 if Sebastian started watching the movie at 17:30. The movie was 1 hour and 54 minutes long.
What is the time zone?For legal, commercial, and social purposes, a time zone is a region that observes a uniform standard time. Instead of strictly following longitude, time zones tend to follow the borders between countries and their subdivisions.
It is given that:
Sebastian started watching a movie at 17:30. The movie was 1 hour and 54 minutes long, but part-way through he paused it for 13 minutes.
The total duration of the movie = 1 hour and 54 minutes
The total duration of the movie with 13 minutes pause
= 1 hour and 54 minutes + 13 minutes
= 2 hours 7 minutes
The movie starts at 17:30
Movies will end at 19:37
Thus, the time when the movie finished is 19:37 if Sebastian started watching the movie at 17:30. The movie was 1 hour and 54 minutes long.
