Mo bought a new car from a showroom. The value, $P, of Mo's car is modelled by
P(t)= 20000(0.9)^(kt)+ 1000, where t is the
number of years since Mo bought the car.
a.) Find the price that Mo paid for the car
After three years, the car was valued at
$16 000.
b.) Find k.
Mo will sell his car when it is worth $5000.
c.) Determine the number of years, after
buying the car, that Mo sells it.

y=3n + 1

step-by-step explanation:

this is wrong because it says the second number is one less and i added one instead

question: use the following table of a school bus during morning pickups to calculate its average speed between 2.8 km and 4.2 km

answer: 42 km/h

explanation: 1.4/0.033 42.42424 = 42 km/h

ending amount = beginning amount / (2^n)

where "n" = number of half-lives (or elapsed time / half-life)

ending amount = 50 mg / (2 ^10 / 5.3)

ending amount = 50 mg / (2 ^ 1.8867924528)

ending amount = 50 m / 3.6981210597

ending amount = 13.5203794557 mg

or about 13.5 mg remain

perimeter = 10 +  √10  units

explanation:

first, we will need to get the length of each line using the distance formula which is as follows:

distance = 

1- length of ab:

ab =   = 5 units

2- length of ac

length of ac is the same as ab = 5 units

3- length of bc:

bc =   =  √10  units

now, we can get the perimeter by adding the side lengths as follows:

perimeter = 5 + 5 +  √10

perimeter = 10 +  √10  units

hope this : )
