What’s the initial value and value after 13 years

we have given the expression .

we need to find the cost of car initially and after 13 years.

we know that at initially t will be 0.

so .

so initially the cost of car is 20000.

when t=13.

so we have plugged corresponding time and found the cost by using the given equation.

if the angular bisector of an triangle bisects the opposite side, prove that the other two sides are equal.

the graph g(x) is f(x) translated 7 units in the negative y direction and translated 2 units in the negative x direction
