A person purchased a used Chevrolet Cavalier for $4500. The car is expected to
decrease in value by 22% each year over
the next several years.
What would be the decay factor of a model
that would represent the value of the car?

£1,219.5

Step-by-step explanation

Original price of car = £4500,

If the car depreciates by 10% after first year

New price = 90% of 4500

New price = 0.9 * 4500

New price = £4050

Second year

Price = 90% of 4050

Price = 0.9 * 4050

Price = £3,645

Third year:

Price = 90% * £3,645

Price = 0.9 * £3,645

Price = £3,280.5

Decrease in value = £4500 -  £3,280.5 = 1,219.5

Hence the  value of the car would have decrease by  £1,219.5 after 3 years

Step-by-step explanation:

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
