A map is represented on a coordinate grid. Town A is located at (-8, 2) and Town B is located
at (10, 8). Town C is the midpoint between Town A and Town B.
If each unit represents 1 mile, the approximate distance from Town A to Town C is
1 point
miles.
The approximate distance from Town A to Town C is 12.5 miles.
What is the midpoint?
The midpoint of a line segment is a point that lies halfway between 2 points. The midpoint is the same distance from each endpoint.
To find the midpoint of Town A and Town B, you need to find the average of the x-coordinates and the average of the y-coordinates.
The x-coordinate of Town A is -8 and the x-coordinate of Town B is 10, so the average is (10 - (-8))/2 = 9/2 = 4.5.
The y-coordinate of Town A is 2 and the y-coordinate of Town B is 8, so the average is (8 - 2)/2 = 6/2 = 3.
Therefore, Town C is located at (4.5, 3).
To find the distance from Town A to Town C, you can use the distance formula, which is the square root of the difference in x-coordinates squared plus the difference in y-coordinates squared.
The distance from Town A to Town C = √((4.5 - (-8))^2 + (3 - 2)^2) = √(12.5^2 + 1^2) = √(156.25 + 1) = √(157.25) = 12.5 miles
Hence, the approximate distance from Town A to Town C is 12.5 miles.

What is a 45 degree triangle called?.
A 45-degree triangle is called a right-angle triangle.
A 45-degree angle is exactly half of a 90-degree angle formed between two rays.
It is equal to half of a straight angle or a 90-degree angle. An angle bisector of a 90-degree angle creates two equal 45-degree angles. The 45-degree angle can be found in many everyday objects, such as scissors, doors, and windows. It is also known as the angle created by a square's diagonal and its sides.
It is an acute angle and two angles measuring 45 degrees form a right angle or a 90-degree angle. We know that an angle is formed when two rays meet at a vertex.

The scale factor in the dilation can be found by comparing the coordinates of the original image (A) and the new image (B). The coordinates of A and B must be provided in order to determine the scale factor.
What is the scale factor in the dilation if the coordinates?The scale factor in the dilation can be found by comparing the coordinates of A and B. The x-coordinate of A is -7 and the x-coordinate of B is -4, which means that the x-coordinate of B is 3 units closer to the origin than the x-coordinate of A. Similarly, the y-coordinate of B is 3 units closer to the origin than the y-coordinate of A. Therefore, the scale factor in the dilation is 3. This means that the image of A is 3 times larger than the preimage, and the image of B is 3 times closer to the origin than the preimage of A. The scale factor can be found by dividing the distance between the coordinates of A by the distance between the coordinates of B. For example, if the coordinates of A are (4,5) and the coordinates of B are (8,10), the scale factor would be 2, as the distance between the coordinates of B is twice the distance between the coordinates of A. It is important to note that the scale factor applies to both the x and y coordinates and is the same value for both.To learn more about coordinates of Care refer to:

I seriously need help on this question, can someone help?
Answer:
a. A + C < B + C
Step-by-step explanation:
when we know that A < B, then adding the same amount to both sides did not change the relationship between both sides.
this is like having a balance with 2 cups. one side is heavier than the other, so the heavier cup is down.
if we add the same weight to both cups, the situation will not change.
that is why a. is the right answer.
b. would only be right, if C is negative.
for positive C the same argument as for A applies. a smaller amount (or weight) stays smaller also after multiplying both sides by the same number.
but because this option would only be right for a subset of the possible values, this is not true in general.
c.
this is not true at all.
if we multiply the expression by -1, then the inequality sign has to flip. < becomes >, > becomes <.

Alex ran 4 1/2 kilometers in 3/4 of an hour. How many kilometers he ran per hour?
First convert the distance she ran from a mixed number to a improper fraction:
• 4-1/2 equals 9/2.
Since this a unit rate problem divide the km by the time traveled.
• 9/2 (km) ÷ 3/4 (hour). When you divide a number by a fraction use (Keep-Change-Flip).
• 9/2 × 4/3 = 36/6 miles/hour.
That's means 36/6 = 18/3 = 6 km/ hour.
What is the value of K if ½ is a root of equation x² KX 5 4 0?.
So, the value of k that makes 1/2 a root of the equation x^2 - kx - 5 = 0 is 11.
A root of an equation is a value that satisfies the equation when it is set equal to zero. In other words, a root of an equation is a solution to the equation of the form x = constant.
The equation x^2 - kx - 5 = 0 is a quadratic equation, which can be factored into (x - r1)(x - r2) = 0 where r1 and r2 are the roots of the equation.
In this case, we can use the fact that 1/2 is a root of the equation x^2 - kx - 5 = 0
We can use the factored form of the equation and substitute x = 1/2
(x-1/2) (x-r2) = 0
Then, we can set each factor equal to zero and solve for r1 and r2:
x - 1/2 = 0 and x - r2 = 0
x = 1/2 and x = r2
We can use the quadratic formula to find the value of r2:
x = (-b ± √(b^2 -4ac) ) / 2a
We can substitute the values in the equation x^2 - kx - 5 = 0
x = (-(-k) ± √((-k)^2 - 41(-5)) ) / 2*1
x = (k ± √(k^2 + 20) ) / 2
x = (k ± √(k^2 + 20) ) / 2
r2 = (k + √(k^2 + 20) ) / 2
Now we have two values of x that satisfies the equation x^2 - kx - 5 = 0
x = 1/2 and x = (k + √(k^2 + 20) ) / 2
We can use the first value x = 1/2 and substitute it back into the original equation:
(1/2)^2 - k(1/2) - 5 = 0
1/4 - k/2 - 5 = 0
k/2 = 6 - 1/4
k = 12 - 1
k = 11
Therefore, the value of k that makes 1/2 a root of the equation x^2 - kx - 5 = 0 is 11.

A5=768 and a2=12; given two term in a geometric equence find the 8th term and the recurive formula
The recursive formula for this geometric sequence is , an = a(n-1) * 64, where a(n-1) is the previous term of the sequence.
What is geometric ?
A geometric sequence is a sequence of numbers such that the quotient between any two consecutive terms is always the same, this common ratio is denoted by "r" and the first term of the sequence is denoted by "a1". A geometric sequence can be represented by the following formula
a_n = a_1 * r^(n-1)
Given a5=768 and a2=12, we can find the value of the common ratio (r) by dividing the two terms:
r = a5 / a2 = 768 / 12 = 64
To find the 8th term of the geometric sequence, we can use the formula:
an = a1 * r^(n-1)
where a1 is the first term, r is the common ratio, and n is the position of the term.
Given the 8th term, we can substitute the values
a8 = a1 * r^(8-1) = a1 * 64^7 = a1 * 64^7
To find the recursive formula, we can use the formula:
an = a(n-1) * r, where a(n-1) is the previous term of the sequence
So the recursive formula for this geometric sequence is , an = a(n-1) * 64, where a(n-1) is the previous term of the sequence.

When using substitution to solve a linear system how do you know if the system is inconsistent?.
The first step in determining whether a linear system is inconsistent is to identify whether the lines are parallel. Check to see if the lines have a y-intercept in common, if so.
This result establishes an inconsistent system due to the fact that two parallel lines with distinct y-intercepts will never intersect.
If there is at least one solution to a linear equations system, it is said to be a consistent system. The system is regarded as inconsistent if there is no solution.
When the lines are parallel to one another, a system of linear equations cannot become inconsistent in any other way. The slope of parallel lines is the same. Therefore, comparing the slopes is a good way to ascertain whether the system is inconsistent. The comparison is simple if the linear equations are written in the point-slope or slope-intercept form. In order to determine the coefficient of x and compare slopes, it is a good idea to solve for y on all equations that are in a different form and express them in the slope-intercept form. The equation system is inconsistent if the slopes are equal to one another.

Suppose you through a ball horizontally. How is the way the ball moves similar to the motion of the planets around the sun?
The forces acting on a horizontally moving ball in the air are gravity or the force of its own weight, and the force that displaces the ball in the horizontal direction.
What is force?Force is an external agent that acts on a body to cause it to move or stop. There are various types of forces, such as magnetic forces, nuclear forces, frictional forces, and so on.
The product of a moving body's mass and acceleration yields force, which is derived from Newton's second law of motion. As a result, as the mass of the object increases, the force required to change its state increases.
The forces acting on a moving ball horizontally are the normal force that displaces it in that direction and the downward force of gravitation equal to its weight. Air resistance acting on the ball can also be considered.

An architect is designing a water fountain for a park. She uses the given function to model the water jets flowing from the fountain's nozzles,
where h(x) gives the height of the water jet, in feet, x feet from its starting point.
The two adjacent columns that show an interval with an average rate of change of -0.3 are column 7ᵗʰ and 8ᵗʰ.
We have a function used by an architect is designing a water fountain for a park. The function is defined as h(x) = - x²/20 + x + 15
where h(x) --> height of the water jet, in feet,
x --> distance from its starting point in feet.Also , the average rate of change = - 0.3
Average rate of change is used to measure the change in value of function per unit, on average over an interval. It is derived from the slope line which is formed bu joining the end points of graph. Formula is represented as
A(x) = {F(b) - F(a)}/(b - a)
where b and a are end points of interval.
In this case, this formula is used as
A(x) = {H(x₂) - H(x₁)}/(x₂ - x₁ )
=> -0.3 = {H(x₂) - H(x₁)}/(x₂ - x₁ )
As we see in above figure the difference between the any two values of x is equals to 2 i.e., the final value - initial value = 2 in an interval.
So, x₂ - x₁ = 2
=> -0.3 = {H(x₂) - H(x₁)}/2
=> -0.3× 2 = H(x₂) - H(x₁)
=> -0.6 = H(x₂) - H(x₁)
=> H(x₂) = H(x₁) - 0.6
so, the columns which follows this relationship are the following
distance , x 12 14
Height of jet , h(x) 19.8 19.2
Hence, the required relationship is H(x₂) = H(x₁) - 0.6.

Angles greater than 90 degrees are obtuse angles, angles less than 90 degrees are acute angles, and angles at 90 degrees are right angles.
Anybody know how to solve this??? Plsss
Answer:
12,34
Step-by-step explanation:
For 'a'
8x=(2x+72) [vertically opposite angle]
8x-2x=72
6x=72
x=72/6
x=12
For 'b'
4x+20+x-10=180° [ being straight angle ]
4x+x+20-10=180°
5x+10=180°
5x=180-10
x=170/5
x=34
Which relation is a function?
Responses
{(1, 2), (2, 3), (3, 4), (4, 5)}
{(1, 2), (3, 4), (5, 6), (1, 8)}
{(1, 2), (2, 1), (1, 3), (3, 1)}
{(0, 2), (0, 4), (0, 6), (0, 8)}
The relation that is a function is
{(1, 2), (2, 3), (3, 4), (4, 5)}
Option A is the correct answer.
What is a function?A function is a relationship between inputs where each input is related to exactly one 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,
A function can have different inputs but the same output.
i.e many to one.
But a function can not same input and different output.
i.e one to many.
Now,
{(1, 2), (2, 3), (3, 4), (4, 5)}
This is a function because each input has a different output.
This is a one-to-one function.
{(1, 2), (3, 4), (5, 6), (1, 8)}
This is not a function because 1 has different outputs 2 and 8.
{(1, 2), (2, 1), (1, 3), (3, 1)}
This is not a function because 1 has different outputs 2 and 3.
{(0, 2), (0, 4), (0, 6), (0, 8)
This is not a function because 0 has different outputs 2, 4, 6, and 8.
Thus,
{(1, 2), (2, 3), (3, 4), (4, 5)} is a function.
