a. A model for the difference in feet between car A and car B is d(t) = = 0.35t² - 3t - 1.

b. The difference in feet between car A and car B after 10 seconds is 4 feet

c. To tell which car is in the lead,

Since the distance in feet of car A from the starting line is modeled by the function f(t) = 0.25t² + 22t - 1, where t is the time in seconds since the start of the race.

Also, the distance in feet of car B from the starting line is modeled by the function g(t) = -0.1t² + 25t.

The difference in distance between car A and car B d(t) is the difference between their distance from the starting line.

So, d(t) = f(t) - g(t)

= 0.25t² + 22t - 1 - ( -0.1t² + 25t)

= 0.25t² + 22t - 1 + 0.1t² - 25t

= 0.35t² - 3t - 1

So, a model for the difference in feet between car A and car B is d(t) = = 0.35t² - 3t - 1.

Since the difference in distance in feet between car A and car B  is d(t) = 0.35t² - 3t - 1.

To find the difference in distance after 10 seconds, we substitute t = 10 into d(t).

So, d(t) = 0.35t² - 3t - 1.

d(10) = 0.35(10)² - 3(10) - 1

= 0.35(100) - 30 - 1

= 35 - 31

= 4 feet

So, the difference in feet between car A and car B after 10 seconds is 4 feet

Since the difference in distance in feet between car A and car B  is d(t) = 0.35t² - 3t - 1

= f(t) - g(t)

Since

So, to tell which car is in the lead,

Step-by-step explanation:

Based on the length of the subway sandwich, the length of the larger pieces is 11 feet.

Assume that the length of the shorter pieces is x.

The length of the larger pieces is therefore 5 + x.

The relevant equation to find the length is:

52 = x + x + x + x +x + 5 + x + 5 + x

52 = 7x + 10

x = (52 - 10) / 7

= 6 foot

The length of the larger pieces is:

According to transitive property, 0 + x + 13 = x + 13 and also x + 13 is equal to 13 + x. Thus, we can equally say that; 0 + x + 13 is equal to 13 + x

We are told that the Transitive Property states that if a = b and b = c, then a = c.

Now, if a = 3 for example, then by the transitive property, it means that b and c must both also be 5.

Now, we want to apply the the transitive property to show that the expressions 0 + x + 13 and 13 + x are equivalent.

Now, the expression 0 + x + 13 is equal to x + 13.

Now, according to transitive property, 0 + x + 13 = x + 13 and also x + 13 is equal to 13 + x. Thus, we can equally say that;

0 + x + 13 is equal to 13 + x

Geometric order is a geometric series or sequence. By multiplying the terms of a geometric series, we arrive to conclusions. A geometric sequence, to put it simply, progresses from one term to the next by multiplying (or dividing) each phrase by the same constant value or number.

A mathematics series is a sum of an infinite number of terms with the objective of maintaining a constant ratio between the progressing terms.

Given:

In the n-th year, the rent will be ...

 an = a1·r^(n-1) . . . . . . . . . r is the year on year ratio: 1+rate of increase

 an = 1100·(1.095^(n-1))

Then the rent in the 8th year is ...

 a8 = 1100·(1.095^(8-1)) ≈ 2076.30

The rent in the 8th year would be $2076.30.

There are three possible positive and one negative root for the equation.

A polynomial is defined as a mathematical expression that has a minimum of two terms containing variables or numbers. A polynomial can have more than one term.

We have been given the equation as

Check the polynomial "as is" for positive zeros, the symbol changes three times. This means that you might either have one or three positive zeros. If they are imagined, they will depart in pairs.

So changes signs 3 times: possible positive roots 3 or 3-2=1

The polynomial must be rewritten as  [tex]f(-x)[/tex] for negative zeroes, or
