Answer: A = 19524.63
Step-by-step explanation:
Since the car depreciate in value , the exponential function to model the situation will be
A = P
Where :
A = amount after n years
P = principal
r = rate %
n = number of years
substituting each values , the exponential function to model the situation becomes:
A = 35000
To find the value of the car in 2015 , it means we are finding the value after 7 years, therefore , when n = 7
A = 35000()
A = $19524.63
Therefore , the amount in 2015 will be A = $19524.63
Answer:
5
Step-by-step explanation:
The ones place is the one most to the right that isn't after a decimal point.
First convert all of the fractions into the same denominator. 1/3 = 2/6. Add the new fraction of history books and the fraction for english books. 2/6 + 1/6 = 3/6. Subtract the total from 1 or 6/6. 6/6 - 3/6 = 3/6. The answer is 3/6 or 1/2 when reduced. 50% or 1/2 of the books are science books.
Answer:
I don't understand the first one
X1=(-16√16^2-4*1*9)/(2*1) = (-16 - 2*√55)/ 2=-15.416
X2=(-16+√16^2-4*1*9)/(2*1) = (-16+2*√55)/2=-0.584
