The distance between points F and G is 15 units.

The length of the line segment connecting two points on a plane is known as the distance between the points. The formula for distance between two points ([tex]x_{1}[/tex],[tex]x_{2}[/tex]) and ([tex]y_{1}[/tex],[tex]y_{2}[/tex]) is given by

distance between two points =[tex]\sqrt{(x_{1}-x_{2})^2+(y_{1}-y_{2})^2 } }[/tex]

The equation can be used to calculate the distance between any two locations on an x-y plane or coordinate plane.

The point F is (-9,14) and point G is (1,-19)

If Martina has 16 cars available to rent, and if c is the number of cars she would have left after renting r of them, then the equation relating c to r will be c = 16 - r, and the number of cars she would have been left with after renting 14 of them is calculated to be 2.

An algebraic expression is a type of expression consisting of both numerals and letters.

If Martina has a total of 16 cars available to rent, then the equation or algebraic expression relating c to r is,

c = total number of cars available to rent - r

c = 16 - r

After renting 14 of the total cars available, then the number of cars left can be calculated using this equation,

c = 16 - r

c = 16 - 14

c = 2

Using it's formula, the average rates of change are given as follows:

a) 30 meters per second.

b) -10 meters per second.

The average rate of change of a function is given by the change in the output divided by the change in the input. Hence, over an interval [a,b], the rate is given by the following equation:

[tex]r = \frac{f(b) - f(a)}{b - a}[/tex]

For item a, taking the data from the table, we have that:

Hence the rate is given as follows:

r = (138 - 0)/(4.6 - 0) = 30 meters per second.

For item b, taking the data from the table, we have that:

The seventh term of the given geometric progression is: 729.

A geometric progression, sometimes referred to as a geometric sequence in mathematics, is a series of non-zero numbers where each term following the first is obtained by multiplying the preceding one by a constant, non-zero value known as the common ratio.

Now,

Given GP: 1, -3, 9, .....

Here, a₁ = 1

a₂ = a₁ (r)

=> r = 3

Thus, a₇ = a₁ (r⁷⁻¹) = 1 (3⁶) = 729.

The sequence partially defined by the recursive formula f(n+1) = f(n)+2.5, n≥1 is -10, -7.5, -5, -2.5, …

Given recursive formula is f(n+1) = f(n)+2.5, n ≥ 1.

So the first term of the sequence is f(1) since n ≥ 1.

Given options for the sequences are:

a. 2.5, 6.25, 15.625, 39.0625, …

b. 2.5, 5, 10, 20

c. -10, -7.5, -5, -2.5, …

d. -10, -25, 62.5, 156.25

We compare the first term of each sequence with the given recursive formula.

a.  2.5, 6.25, 15.625, 39.0625, …

In this sequence, the first term, f(1) = 2.5

Using recursive formula, f(2) = f(1) + 2.5 = 2.5 +2.5 = 5.

But the second term in the given sequence is 6.25. So the recursive formula does not match with this sequence.

b.2.5, 5, 10, 20

Here, f(1) = 2.5

By the recursive formula, f(2) = f(1) + 2.5 = 5

f(3) = f(2) + 2.5 = 5 +2.5 = 7.5, which does not match with the third term of the given sequence. So this sequence is not defined by the recursive formula.

c. -10, -7.5, -5, -2.5, …

Here, f(1) = -10

Using recursive formula, f(2) = f(1) + 2.5 = -10 + 2.5 = -7.5

f(3) = f(2) + 2.5 = -7.5 +2.5 = -5

f(4) = f(3) +2.5 = -5 +2.5 = -2.5

So far the recursive formula matches with the given sequence. So the sequence defined partially by the recursive formula, f(n+1) = f(n)+2.5, n ≥ 1 is -10, -7.5, -5, -2.5, …

d.  -10, -25, 62.5, 156.25

But the sequence which matches with the recursive formula and starting with -10 is option c. So this sequence does not need to be verified.

Answer:

1000

Step-by-step explanation:

The closest 1000 to 598 is 1000.

The absolute value equation used to solve this problem: | x - 82 | = 12, where x = grade.

Now,

Given:

Let 'x' be the value that gives the value of grades.

The absolute value equation to find the grades will be given by: | x - 82 | = 12

=> x - 82 = ± 12

For maximum value of the grades, x - 82 = 12

=> x = 82 + 12

=> x = 94.

For minimum value of the grades, x - 82 = -12

=> x = 82 - 12

=> x = 70.

Hence, The absolute value equation used to solve this problem: | x - 82 | = 12, where x = grade.

If AB = 6y - 14, BC = 10 - 2y then the value of AC = 8.

In geometry, the midpoint is the point in the middle of a line segment. It is equidistant from both endpoints and serves as the segment and endpoint centroid. It cuts the segment in half.

Given: AB = 6y - 14, BC = 10 - 2y

Since B is the midpoint of AC, AB = BC then

6y - 14 = 10 - 2y

Add 14 on both sides of the equation, and we get

6y - 14 + 14 = 10 - 2y + 14

6y = - 2y + 24

Add 2y on both sides of the equation

6y + 2y = - 2y + 24 + 2y

simplifying the above equation, we get

8y = 24

y = 24/8

y = 3

Substitute the value of y in AC then we get

AC = 2(6(3) - 14)

= 2(4)

AC = 8

Therefore, the value of AC = 8.

Step-by-step explanation:

the perimeter of a rectangle is

2×length + 2×width

for our rectangle here that means

2×(5x) + 2×(x - 3) = 42

10x + 2x - 6 = 42

12x - 6 = 42

12x = 48

x = 4

length = 5x = 5×4 = 20 in.

width = x - 3 = 4 - 3 = 1 in.

a) The square that does not touch one of the perimeter squares is the square 3C.

b) The area is 10 units.

The perimeter squares are the outer squares of the image. So, the only square that does not touch one of the perimeter squares is the central one. To identify it, you need to first see in which row it is, and you can see that it is row 3.

Then you need to identify the column, the central square is in column C.

Then the square that does not touch one of the perimeter squares is the square 3C.

What is the combined area of rows 4 and 5?

Let's say that each square has an area of one unit. Now, we have 5 columns, then each row has 5 squares, then the area of each row is 5 units.

If Jim is running a race against his best friend Ryan and Jim runs at a rate of 18 miles in 3 hours while Ryan runs at a rate of 11 miles in 2 hours, then Jim can run 0.5 miles further compared to his friend Ryan.

If Jim runs at a speed of 18 miles in 3 hours, it can be represented as,

Speed = distance / time = 18 miles / 3 hours = 6 miles per hour

As Ryan runs at a rate of 11 miles in 2 hours, it can be given as,

Speed = distance / time = 11 miles / 2 hours = 5.5 miles per hour

To determine how much further Jim can run in an hour compared to his friend Ryan,

Distance ( Jim ) = speed x time = 6 x 1 = 6 miles

Distance ( Ryan) = speed x time = 5.5 x 1 = 5.5 miles

The distance that Jim can run further in an hour can be calculated by subtraction.

Distance ( Jim ) - Distance ( Ryan) = 6 - 5.5 = 0.5 miles

Thus, Jim can run 0.5 miles further in an hour compared to his friend Ryan.
