I’m not sure if your asking help to factor the equation. Here is the answer to the equation that I factored. -v^3(v^72-2v^24 + 1) Hope that helps you.
We have been given that a virus has infected 400 people in the town and is spreading to 25% more people each day. We are asked to write an exponential function to model this situation.
Since the number of infected people is increasing, so our model will be exponential growth model.
An exponential growth function is in form
, where,
y = Final amount,
a = Initial amount,
r = Growth rate in decimal form,
x = Time.
Let us convert 25% into decimal form.
![25\%=\frac{25}{100}=0.25](https://tex.z-dn.net/?f=25%5C%25%3D%5Cfrac%7B25%7D%7B100%7D%3D0.25)
The initial number of infected people is
, so our function would be
.
![y=400(1.25)^x](https://tex.z-dn.net/?f=y%3D400%281.25%29%5Ex)
To find the number of infected in 10 days, we will substitute
in our given formula as:
![y=400(1.25)^{10}](https://tex.z-dn.net/?f=y%3D400%281.25%29%5E%7B10%7D)
![y=400(9.3132257461547852)](https://tex.z-dn.net/?f=y%3D400%289.3132257461547852%29)
![y=3725.290298\approx 3725](https://tex.z-dn.net/?f=y%3D3725.290298%5Capprox%203725)
Therefore, there will be approximately 3725 infected people in 10 days.
Answer: Simon has a higher chance of winning
Step-by-step explanation: The possibility of Smith winning is 16/52 and the possibility of Simon pulling an even card is 20/52.
(20/52 is more than 16/52)
Answer:
hello welcome to brainly here's your answer
Step-by-step explanation:
Let One Cup of Coffee is X and one doughnut be Y
So X+3Y=4.10 and 2X+2Y=4.60 => X +Y=2.30
=> X+3Y-(X+Y)=4.10-2.30 => 2Y=1.80 => Y=0.90
and X+0,90=2.30 => X=2.30-0.90=1.40
So answer is 1 cup of coffee is $1.40 and one doughnut is $0.90
