Given LM- MP and L, M, and P are collinear, which of the following is false about the relationship of L, M. and P?
(1) LM = MP (2) M is the midpoint of LP (3) LM +MP=180 (4) M bisects LP
Answers
The statement that is false about the relationship of L, M, and P that are collinear is: 3. LM + MP = 180.
What are Collinear Points?When two or more points are on a straight line, they are classified as collinear points.
What is the Midpoint of a Segment?The point on a line segment that bisects the segment into two equal parts is referred to as the midpoint of the line segment.
We are given that:
LM = MP, since, points L, M. and P are collinear points, therefore, it implies that point M is the midpoint of segment LP.
It also means that M bisects segment LP since LM = MP, where M is the midpoint of segment LP.
Thus, the statement that is false about the relationship of L, M, and P that are collinear is: 3. LM + MP = 180.

1.25%. North Carolina's current population is about 9,656,401 people.
a. What is the equation that models Georgia's population growth?
b. What is the equation that models North Carolina's population growth?
c. What do the graphs of the equations look like? Graph the equations on the provided grid.
Answers
The equation for population growth in Georgia is P = 8,815,210 ( 1.013 )ⁿ ( red line on the graph) and the equation for population growth in North Carolina is P = 9,656,401 ( 1.0125)ⁿ ( blue line on the graph).
We are given that:
For Georgia:
Growth rate of population = 1.3 %
Population = 8,815,210
For North Carolina:
Growth rate of population = 1.25 %
Population = 9,656,401
a) The equation that models Georgia's population growth can be found out by using the concept of compound interest as the population will increase in a compounded way.
So, the equation will be:
P = 8,815,210 ( 1 + 1.3 % )ⁿ
P = 8,815,210 ( 1.013 )ⁿ
where P is the population after n years.
b) the equation that models North Carolina's population growth:
P = 9,656,401 ( 1.0125)ⁿ
where P is the population after n years
Therefore, we get that, the equation for population growth in Georgia is P = 8,815,210 ( 1.013 )ⁿ ( red line on the graph) and the equation for population growth in North Carolina is P = 9,656,401 ( 1.0125)ⁿ ( blue line on the graph)

help Finding the initial amount and rate of change given a table for a linear function
Answers
(a) The table clearly shows distance gets smallers as time passes, so the first choice is correct.
Since we know the rate at which the escalator moves is constant, we know that the average rate of change of the escalator's distance from the first floor is the same across any time interval we choose. Take for instance the average rate of change from [tex]t=6[/tex] to [tex]t=9[/tex]. If [tex]d(t)[/tex] denotes distance at time [tex]t[/tex], then the average rate of change over these 3 seconds, and at every point in time for that matter, is
[tex]\dfrac{d(9) - d(6)}{9 - 6} \dfrac{\rm cm}{\rm s} = \dfrac{890 - 980}{9 - 6} \dfrac{\rm cm}{\rm s} = -30 \dfrac{\rm cm}{\rm s}[/tex]
In other words, the distance from the first floor is decreasing at a rate of 30 cm/s. (negative sign = decreasing)
(b) At the start, when [tex]t=0[/tex], suppose Alan's distance from the first floor was [tex]x[/tex]. For every second that passes, we know the distance from the first floor decreases by 30 cm. This would mean that after [tex]t[/tex] seconds have passed, the distance would have decreased by a total [tex]30t[/tex] cm.
This tells us that Alan's distance from the first floor at any time [tex]t\ge0[/tex] is
[tex]d(t) = x - 30t[/tex]
Using any of the values from the table, we can solve for [tex]x[/tex].
[tex]t=6 \implies d(6) = x - 30\cdot6 \implies 980 = x - 180 \implies x = 1160[/tex]
which places Alan 1160 cm = 11.6 m from the first floor at the start.
Suppose x and y vary together such that y = 2 x 8 . suppose x varies from x = 3 to x = 9.5 . over this interval, how much does x change by?
Answers
A function assigns the values. The value of x changes by 6.5, and the value of y changes by 13.
What is a Function?A function assigns the value of each element of one set to the other specific element of another set.
Given that x and y vary together such that y = 2x+8. Also, the of x varies from x = 3 to x = 9.5. Therefore, we can write,
x change by = Maximum value of x - Minimum value of x
= 9.5 - 3
= 6.5
Further, the minimum and the maximum value of y will be when the value of x is minimum and maximum, this is because the function is linear. Therefore, we can write,
Minimum value of y, y = 2(3) - 8 = -2
Maximum value of y, y = 2(9.5) - 8 = 11
y change by = Maximum value of y - Minimum value of y
= 11 - (-2)
= 11 + 2
= 13
Hence, the value of x changes by 6.5, and the value of y changes by 13.

if the original patio measures 8 feet by 8 feet.
Answers
Answer:
Length = x + 3 ft
Width = x - 3 ft
Area of new patio = x² - 9 sq ft
If original side length = 8, new area = 55 sq ft
Step-by-step explanation:
The original patio has side length of x
If one side is reduced by 3 we get (x - 3) as the new side
If the side is increased by 3' we get (x + 3) as the new side
Area of new Patio = (x - 3)(x+3) = x² - 9
Original patio is 8 x 8
New patio width = 8 - 3 = 5
New patio length = 8 + 3 = 11

Which statements have an inverse that is false?
1.If two angles are congruent, then they are vertical angles.
2.If two angles are a linear pair, then they are supplementary.
3.If two angles are acute, then their sum is less than 90.
4.If two angles are complementary, then both angles are acute.
Answers
Statement 1 is a false statement.
What are supplementary angle?
Supplementary angles are two angles whose measures add up to 180° . ex 150° and 30°
What are complementary angles?
When the sum of two angles is equal to 90° degrees, they are called complementary angles. For example, 30° and 60° are complementary angles.
What are vertical angles?
Vertical angles are formed when two lines meet each other at a point. A vertical angle and its adjacent angle are supplementary angles, i.e., they add up to 180°What are congruent angles?
Two or more angles that are identical to each other.
False - All vertical angles are considered congruent but not all congruent angles are considered vertical angles. Any acute or obtuse angle may also be considered congruent. True - If 2 angles whose measures add to 180°, it means they are supplementary. They form a linear pair.True - Let one angle be 30° and the other angle is 40° , both of which are acute angles, then their sum is 70°, which is less than 90° True - Both angles in a complementary pair will always be acute. For ex: 30° and 60° are complementary angles , but are less than 90°, so they both are acuteThus we can conclude that all vertical angles are congruent but not all congruent angles are considered vertical angles
