Answer:This is a line, x>0 (miles cannot be negative)

Step-by-step explanation: Cost of renting a car = cost per mile times the number of miles plus the flat fee

We know the cost per mile = .25 and the flat fee

Let x = number of miles and y = cost of renting a car

y = .25x+15

This is in the form y= mx+b which is the slope intercept form of a line.

There are 6 members on a board of directors. If they must elect a chairperson, a secretary, and a treasurer, how many different

Gwar [14]

Answer:

120 different slates of candidates are possible.

Step-by-step explanation:

The order is important.

For example, a slate of John, Rose and Elisa means that John is the chairperson, Rose is the secretary and Elisa is the treasurer. If two of them are exchanged, their roles will also be changed. So we use the permutations formula to solve this question.

Permutations formula:

The number of permutations of x elements from a set of n elements is given by:

$P_{n,x} = \frac{n!}{(n-x)!}$

In this problem, we have that:

6 members will be chosen for 3 roles. So

$P_{6,3} = \frac{6!}{(6-3)!} = 120$

120 different slates of candidates are possible.

Write the rule for the nth term of the following sequence.

denis-greek [22]

Answer:

$2^{n-3}$ is the nth term of the given sequence.

Step-by-step explanation:

The sequence given is

$\frac{1}{4},\frac{1}{2},1,2,4 .....$

We can clearly see that 1st term is $\frac{1}{4}$ and 2nd term is $\frac{1}{2}$

2nd term is obtained by multiplying the 1st term by 2.

2nd term is $\frac{1}{2}$ and 3rd term is 1.

3rd term is obtained by multiplying the 2nd term by 2.

3rd term is 1 and 4th term is 2.

4th term is obtained by multiplying the 3rd term by 2.

Clearly, the given series is a Geometric Progression(GP) with

First term, $a = \frac{1}{4}$

Common Ratio, $r = 2$

We know that $n^{th}$ term for a GP is:

$a_n = ar^{n-1}$

Putting values of a and r

$a_n = \dfrac{1}{4}2^{n-1}\\a_n = \dfrac{1}{2^{2} }2^{n-1}\\a_n = 2^{n-1-2}\\a_n = 2^{n-3}$

Hence, $2^{n-3}$ is the nth term of the given sequence.

Jemma is three times as old as Angie. Five years from now the sum of their ages will be 34 years. What are their present ages?

Lapatulllka [165]

Answer: Angie = 6, Jemma = 18

Step-by-step explanation:

Let x represent the current age of Angie

Current Age Age 5 years from now

Angie: x x + 5

Jemma: 3x 3x + 5

5 years from now the sum of their ages is 34

(x + 5) + (3x + 5) = 34

4x + 10 = 34

4x = 24

x = 6

Angle's current age is x = 6

Jemma's current age is 3x = 3(6) = 18

A condition expresses a hypothesis about the state of its world at that point in time.a. False b. True

Alina [70]

Answer:

The Correct option is B: True

Step-by-step explanation:

A condition is a state of something with respect to its quality, working order, or appearance at a particular point in time. Hence, a condition can tell if a hypothesis is true or false at that time, but once the condition changes, it can change the conclusion and hence the hypothesis also.
