The midpoint becomes Midpoint M is 3/2, 6.
According to the statement
We have to find that the midpoint.
So, For this purpose, we know that the
Midpoint is the the point on a line segment or an arc that is equidistant, when measured along the line or the arc, from both endpoints.
From the given information:
The end points of AB are A (-7,7)and B (10,5).
Then
Midpoint M = Midpoint of A, Midpoint of B
Then
Midpoint M = -7+10 /2, 7+5/2
Midpoint M = 3/2, 12/2
Midpoint M = 3/2, 6.
Then the midpoint of the AB becomes the 3/2, 6. which represent the 3/2 is the x coordinates and the y coordinates is a 6.
So, The midpoint becomes Midpoint M is 3/2, 6.

Find an equation of the tangent line to the curve at the given point. y = ex cos(x) , (0, 1)
The equation of the tangent line to the curve at the given point is given by: y = x + 1.
What is the equation of a line to the curve?A line's equation has the standard form ax + by + c = 0. Here, the variables are x and y, the coefficients are a and b, and the constant term is c. It is a first-order equation with the variables x and y. The coordinates of the point on the line shown in the coordinate plane are represented by the values of x and y.Now,
Given:
Equation of line: y = [tex]e^{x}[/tex] cos(x)Given point = (0,1)To find: Equation of a tangent line through the given point.
Finding:
y = [tex]e^{x}[/tex] cos(x)
By product rule of differentiation, y' = [tex]e^{x} sin(x) +e^{x} cos(x)[/tex]
For x = 0, y' (0) = 1 (0) + 1( 1) = 1 = slope of the line
Now, we know: equation of a line is given by:

What is the probability of rolling either a 5 or a 6 using a normal six-sided die?
1/3 is the probability of rolling either a 5 or a 6 using a normal six-sided die.
Define probability?Probability can be defined as the ratio between the number of favorable outcomes and the total number of outcomes of an event.
Given:
Six-sided dice rolled once
Let n be the number of outcomes
let x be the number of favorable outcomes
We know that,
[tex]Probability=\frac{x}{n}[/tex]
When the six-sided dice roll, The possible outcomes are,
[tex]\{1,\;2,\;3,\;4,\;5,\;6\}[/tex]
Therefore,
[tex]Number\;of\;outcomes,\;n=6[/tex]
[tex]Probability\;rolling\;5\;is\;\frac{1}{6}[/tex]
[tex]Probability\;rolling\;6\;is\;\frac{1}{6}[/tex]
Therefore, Probability of rolling either 5 or 6 is,
[tex]P(5\;or\;6)=\frac{1}{6} +\frac{1}{6}[/tex]

The correct answer for given question is 6.
If every element of a non-empty set X has only one image or range to a non-empty set Y, a relation 'f' is said to be a function.
Or
If 'f' is the function from X to Y and (x,y) f, then f(x) = y, where y is the image of x and x is the preimage of y under function f. It is written as;
f: X → Y.
In accordance with the conditions stated in the question:
f(x) = 3x^2 and g(x) = 4x^3 + 1
The composition of functions is defined as fog(x) = f(g(x)), where the input for the function f(x) is the actual expression of the function g(x) in terms of "x":
f(g(x)) = f(4x^3 + 1)
f(g(x)) = 3(4x^3 + 1)^2
f(g(x)) = 3(4x^3 + 1) (4x^3 + 1)
f(g(x)) = 3(16x^6 + 8x^3 + 1)
f(g(x)) = 48x^6 + 24x^3 + 3
Therefore, the degree of the given expression is 6 (the highest power of the variable ‘x’)

Levi brought a bag containing 50 small candies. He starts eating the candies at a rate of 4 candies per minute. Answer the questions below regarding the relationship between the number of minutes eating and the number of candies left in the bag.
Whoever answers correctly with an detailed explanation will get Brainliest!!!
The independent variable x ,represents minutes and dependent variable is the number of candies eating by Levi because the eating of candies depends on the minutes.
A function relating these variable is Z(x)=4x
So Z(7)=28 meaning In 7 minutes Levi ate 28 candies and number of candies left in the bag is 22.
As given,
Independent variable=x
Dependent variable=Z(x)
Function Z(x)=4x
So, Z(7)=4×7
=28
Candies left in bag =50 -28
=22
Therefore, function relating independent variable x with Z(x)=4x and Z(7)=28 represents number of candies ate by Levi in 7 minutes ,number of candies left in the bag is 22.

two ships leave a harbor at the same time. the first ship heads north at 20 miles per hour, and the second ship heads west at 15 miles per hour. write an expression that gives the distance d between the ships after t hours.
The expression that gives the distance, d, between the ships after t hours is d = 25t
Calculating DistanceFrom the question, we are to write an expression that gives the distance, d, between the ships after t hours
First, we will determine the distance the ships have traveled after t hours
Using the formula,
Distance = Speed × Time
Thus,
The first ship would have traveled
20 × t miles
= 20t miles
The second ship would have traveled
15 × t miles
= 15t miles
Using the Pythagorean theorem,
The distance, d, between the ships after t hours is
d² = (20t)² + (15t)²
d² = 400t² + 225t²
d² = 625t²
d = √(625t²)
d = 25t miles

The present ages of Ann and Julie are 12 years and 8 years, respectively.
What are the current ages of Ann and Julie?
Let x, y be the current ages of Ann and Julie, whose features are synthetized in the following linear equations:
Ann is 4 years older than Julie
x = y + 4
x - y = 4 (1)
4 years ago, Ann was twice as old as Julie
x - 4 = 2 · (y - 4)
x - 4 = 2 · y - 8
x - 2 · y = - 4 (2)

Choose the associated property
The Associative property is not displayed by any of the given equations.
The associative property of several binary operations in mathematics states that the outcome will not change if the parenthesis in an expression are rearranged.
The order in which the operations are carried out within an expression that has two or more instances of the same associative operator in a row doesn't matter as long as the order of the operands is left untouched.
Examples of associative property :
