75 ÷ 8 = 9
Remainder:- 3
So 8 goes in to 75 nine times with 3 left.
8 + 8 + 8 + 8 + 8 + 8 + 8 + 8 + 8 = 72 OR 9 × 8 = 72.
SO,
8 goes into 75 nine times with 3 left.
Hope I helped ya!
Um, I'd say discrete because it's not important. I'd never say it's continuous.
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.
![1-1-r=0.76-1](https://tex.z-dn.net/?f=1-1-r%3D0.76-1)
![-r=-0.24](https://tex.z-dn.net/?f=-r%3D-0.24)
![r=0.24](https://tex.z-dn.net/?f=r%3D0.24)
Let us convert 0.24 into percentage.
![0.24\times 100\%=24\%](https://tex.z-dn.net/?f=0.24%5Ctimes%20100%5C%25%3D24%5C%25)
Therefore, the decay rate is 24%.
Answer:
Step-by-step explanation:
f(x) = (x - 4)(x + 2)
f(x) = x^2 + 2x - 4x - 8
f(x) = x^2 - 2x - 8
