Answer:

The decreasing value of car 1 can be represented by an exponential function and car 2 by a linear function

Car 1: f(x) = $18500(0.94)^{x}$

Car 2: f(x) = 18500 - 1000x

Car 1 would be $10600.40 after 9 years

Car 2 would be $9500.00 after 9 years

There is a significant difference of $1100.40 in value.

Step-by-step explanation:

$f(x) = ar^{x}\\f(0) = a = 18500\\f(x) = 18500r^{x}\\f(1) = 18500r = 17390\\r = \frac{17390}{18500} = 0.94\\f(x) = 18500(0.94)^{x}$

Which solid has zero faces, zero bases, zero vertices, and zero edges?

svlad2 [7]

The only solid <span>zero faces, zero bases, zero vertices, and zero edges is a sphere. The reason why is because it's just round, and it doesn't have anything, just a sphere.

Have a nice day! :)</span>

Father is four times as old as Mary. Five years ago he was seven times as old. How old is the father now?

melamori03 [73]

Answer:

If Father is four times older than Mary, that would be 4 times 10-- which equals 40. Five years ago, Mary must have been 5 years old. So, multiply 7 and 5 and you'll get 35! Father would have been 35 years old.

I hope this helps!
