Answer:

B)  rate of change is 53, your car travels 53 miles every 1 hour .

Step-by-step explanation:

Given : Table for time and distance.

To Find : The rate of change is constant in each table. Find the rate of change. Explain what the rate of change means for the situation.

Solution : We have given that Table for time and distance.

rate  of  change= \frac{change\ in\ y}{change\ in\ x}.

rate  of  change= \frac{212}{4}.

rate of change =  53.

rate  of  change= \frac{318}{6}.

rate of change =  53

rate of change =  \frac{424}{8}.

rate of change =  53.

rate of change =    \frac{530}{10}.

rate of change =  53.

Therefore, B)  rate of change is 53, your car travels 53 miles every 1 hour .

Jameson has $4,300 in credit card debt with 14% interest that he wants to pay off in 24 months. He will need to make monthly pay
neonofarm [45]

Answer:

The answer to this question can be defined as follows:

net paid interest = $ 655. 04

Total cost = $ 4955.04

Step-by-step explanation:

Given values:

loan amount = $ 4,300

monthly payment = $ 206.46

interest rate = 14 %

Time = 2 years

Solution:

yearly payment = one month amount × 12

1 year payment = $ 206.46 × 12

1 year payment =  $2477.52

because Time is 2 year then payment is = $2477.52 *2

2 year payment = $ 4955.04

net interest paid  = total payment - loan amount

                            = $ 4955.04 - $4300

                            = $ 655.04

total  cost = $ 4955.04

net paid interest = $ 655.04

nalin [4]

Answer:

a. 205320

b. 34220

c. 60! / (35)! (25)! + 60!/ (40)!(20)! + 60!/ (45)! (15)!

Step-by-step explanation:

a) The number of ways to dustribute exams among the TA's is:

n / (n - r)!

n= number of things to choose from

r= Choosing r number

60P3= 60! / (60 - 3)!

(60)(59)(58)(57)! / (57)!

=205320

B) The number of ways to dustribute the exams among the TA's is:

n! /(n - r)! r!

60C3= 60! /(60 - 3)! 3!

= 60!/ 57! 3!

= 60 × 59 × 58 / 3 × 2 × 1

= 34220

C) The required number of ways is:

60C25 + 60C20 + 60C15

= 60! / (35)! (25)! + 60!/ (40)!(20)! + 60!/ (45)! (15)!
