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.

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

a) 30 meters per second.

Answer: factor, in mathematics, a number or algebraic expression that divides another number or expression evenly—i.e., with no remainder. For example, 3 and 6 are factors of 12 because 12 ÷ 3 = 4 exactly and 12 ÷ 6 = 2 exactly. The other factors of 12 are 1, 2, 4, and 12.

Step-by-step explanation:

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

Here the first term is, f(1) = -10.

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.

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

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
