Answer:
The midpoint of MN is (7,1)
Add the x coordinates 7+7=14 then you divide that by 2 giving you 7.
Then you add the y coordinates together 6+(-4)=2 then divide by 2 and that gives you 1. Therefore the answer is (7,1)

What is a function?A function has an input and an output.
A function can be one-to-one or onto one.
It simply indicated the relationships between the input and the output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
To find the inflection points of a function, we need to find its second derivative and set it equal to zero.
So,
Let's start by finding the first and second derivatives of f(x).
First, we find the first derivative of f(x).
f'(x) = 15[tex]x^4[/tex] + 8x³ - 260x² - 5x²
Then,
We find the second derivative of f(x):
f''(x) = 60x³ + 24x² - 520x - 10x
Next, we set f''(x) equal to zero and solve for x.
60x³ + 24x² - 520x - 10 = 0
10 (2x² - 13x - 1) = 0
2x² - 13x - 1 = 0
Now,
Using the quadratic formula,
we find the roots of this equation:
x = (13 ± √(13² + 8))/4
x = 13 ± √177) / 4
x = (13 + √177)/4 and x = )13 - √177)/4
x = 2.22 and x = -0.23
Therefore,
There are two points of inflection in the graph of f(x).

Find the length of the hypotenuse of a 45°-45°-90° triangle with a leg length of 77 centimeters.
The sum of the square of the hypotenuse is equal to the sum of the square of the other sides.The length of the hypotenuse of the triangle is l = √14
Pythagoras theoremThe sum of the square of the hypotenuse is equal to the sum of the square of the other sides.
Given that one of the sides is √7, hence;
l^2 = (√7)^2 + (√7)^2
l^2 = 7 + 7
l^2 = 14
l = √14
Hence the length of the hypotenuse of the triangle is l = √14

If 50% of some number is 75, what is 200% of that same number?
Answer:
300
Step-by-step explanation:
A percentage is a unit of proportion that represents a ratio.
For this question let the unknown number be represented by the variable x. We know that 75 is 50% of x, or half of x. This means that we can find the unknown number by doubling 75.
75*2=150This means that x is 150. Next, we need to find 200% of 150. 200% of any number is that number times 2. So, to find the final answer we must once again double 150.
150*2=300So, the final answer is 300.
Answer:
Step-by-step explanation:
270
50% equals to 1/2 so 1/2x=75. Times 2 on both sides you get x=135.
So 135 is x and you multiply 135 by 200%. Which get you 270.

Polygon LMNPQR is shown on the coordinate grid and models the shape of a garden in a park,
Polygon LMNPQR will be dilated with the origin as the center of dilation to create polygon
L'M'N'P/Q'R'. The vertex Q' will be located at (21, 7).
Which rule best represents the dilation?
Dilation involves changing the size of the polygon
The best rule of dilation is [tex](x,y) \to \frac 72(x,y)[/tex]
How to determine the ruleThe coordinates of vertices Q and Q' are given as;
Q = (6,2)
Q' = (21, 7)
The scale factor of dilation is then calculated as:
[tex]k = \frac {Q'}{Q}[/tex]
So, we have:
[tex]k = \frac {(21,7)}{(6,2)}[/tex]
Factorize
[tex]k = \frac {7/2(6,2)}{(6,2)}[/tex]
Divide
[tex]k = \frac {7}2[/tex]
So, the transformation rule is:
[tex](x,y) \to \frac 72(x,y)[/tex]
Hence, the best rule of dilation is [tex](x,y) \to \frac 72(x,y)[/tex]

If a new data point at 12 is added to the graph, The mean will increase more than the median, but both will increase.
What is Mean and Median?Mean of a set of data is defined as the average of all the values. It gives the exact middle point of the data set.
Median of a data set is the element in the middle if the data are arranged in increasing or decreasing order.
Given a graph with the data points as,
1, 2, 2, 2, 3, 4, 4, 4, 5
Mean = (1 + 2 + 2 + 2 + 3 + 4 + 4 + 4 + 5) / 9 = 27 / 9 = 3
Median = 5th term = 3
When 12 is added, new data set has 10 data points.
1, 2, 2, 2, 3, 4, 4, 4, 5, 12
Mean = (1 + 2 + 2 + 2 + 3 + 4 + 4 + 4 + 5 + 12) / 10 = 3.9
Median = average of 5th and 6th term = (3 + 4) / 2 = 3.5
Hence the correct option is The mean will increase more than the median, but both will increase.
