Answer:
Step-by-step explanation:
Use the info given in the exponential equation to find the value of b, the rate of decay.
where v(t) is the value of the car after a certain number of years, t, have gone by, a is the initial value, and b is the rate of decay. We have everything we need but b:
a = 20000
v(t) = 16000 after t = 1 year:
so
b = .8 Taken in context, this means that the car depreciates 20% each year. Now we can solve the problem being asked of us, which is to find the value of the car after t = 5 years:
which simplifies down a bit to
v(t) = 20000(.32768) so
v(t) = 6553.60, choice C.
Prime factorization of 84
2 x 2 x 3 x 7
Correct option 3rd
LCM of 6 and 10
6 = 2 × 3
10 = 2 × 5
LCM = 2 × 3 × 5 = 30
Correct option 3rd
No because the perfect trinomial has a square as the third term and the middle term is a multiple of 2.
---------------------------------------------
Formula
---------------------------------------------
Sum of all exterior numbers = 360°
---------------------------------------------
Apply Formula
---------------------------------------------
z + 45 + 55 + 78 + 74 + z = 360
---------------------------------------------
Combine likes term
---------------------------------------------
2z + 252 = 360
---------------------------------------------
Take away 252 from both sides
---------------------------------------------
2z = 360 - 252
2z = 108
---------------------------------------------
Divide by 2 on both sides
---------------------------------------------
2z = 108
z = 108 ÷ 2
z = 54
---------------------------------------------
Find z + 45
---------------------------------------------
z + 45 = 54 + 45
z + 45 = 99°
---------------------------------------------
Answer: 99°

Answer:
16 carrots per square foot
Step-by-step explanation:
since you want to find the unit rate you must take the 5 square feet to make it 1. Therefore you must divide the 5,but what you do to 1 side you have to do to another so you also have to divide 80 by 5 giving you a ratio of 16:1. Showing that there are 16 carrots per square foot.
