Answer:
B
Step-by-step explanation:
Multiply each ratio by the same number
4x3=12 7x3=21
We have been given that Jackson purchases a new car for $48,000. The car's value can be modeled by the following exponential function: where y represents the car's value and t represents time in years. We are asked to find the decay rate as a percentage.
We know that an exponential decay function is in form , where,
y = Final value,
a = Initial value,
r = Decay rate in decimal form,
x = time.
Upon comparing our given function with standard decay function , we can see that .
Let us solve for r.
Let us convert 0.24 into percentage.
Therefore, the decay rate is 24%.
Yarrr maths.....very tough subject
Add 4x over to 14x, 3=5x2- 18x then add 18x to the other side 3+ 18x= 5x2then divided each side by 5,( 3+18x/5=x2) then square root each side the answer to x would be the square root of 3+18x/5
