Answer:
Option (B)
Step-by-step explanation:
By applying multiplication property of the matrices,
Therefore, system of equations formed will be,
5x + 2y + z = 16
7x - 5y + 2z = 3
-5x + 3y + z = 12
Option (B) will be the correct option.
Answer:
Arc length is equal to 
where 
is the angle in radians and 
is the radius.
Question 1:
So the angle is CFD.
Question 2:
So the angle is AFE.
Question 3:
So the angle is AFB.
Question 4:
So the angle is BFC.
Answer:
TC = 36t + 25
Step-by-step explanation:
The amount paid by Carla as a storage fee or fixed cost = $25
Monthly rent or variable cost = $36
Let the number of months = t
Now we have to find the expression that represents the total cost. Below is the formula to find the expression.
Total cost = Variable cost + Fixed cost
Total cost = 36t + 25
TC = 36t + 25
4 years=48 months
A new car costs 25,000, but she will get 13,000 for her used car as long as she takes good car of it. If she takes good care of her used car and gets 13,000 for it, she will only need to save 12,000 total. We can divide 12,000 by 48 to find out how much Courtney should save minimum each month to afford her new car. 12,000/48=250
You can check to see if this is correct by multiplying 48*250=12,000. Paying 250 for each month of the 48 months will equal the $12,000 that Courtney needs.
Courtney needs to save at least $250 per month to afford her new car in 4 years.
I hope this helps :)
