Answer:
It will take 3.2 hours for 8 inches of snow to fall.
Step-by-step explanation:
You can solve this be going "backwards".
You have 2.5 inches of snow falling per hour for x hours until you get 8 inches of snow, which can be represented like this:
2.5x=8 From here you being to solve by isolating x on one side of the equation. You would divide both sides by 2.5 to do this
2.5x=8
/2.5 /2.5
8 divided by 2.5 is 3.2 and you then get
x=3.2
It takes 3.2 hours for 8 inches of snow to fall
To find out how long it would take for 8 inches of snow to fall at a rate of 2.5 inches per hour, we simply divide the total distance (8 inches) by the speed (2.5 inches per hour), which results in approximately 3.2 hours.
On the question about how long it will take for 8 inches of snow to fall at a rate of 2.5 inches per hour, this is a straightforward problem of rates. We just need to divide the total amount of snowfall (8 inches) by the rate of snowfall (2.5 inches per hour). Therefore, Time = Distance / Speed
Time = 8 inches / 2.5 inches per hour = 3.2 hours.
Therefore, it would take approximately 3.2 hours for 8 inches of snow to fall at this rate.

The cosine function that models the variation is f(x) = 51.4
To find the inches, we would subtract the value of 12 from 52 which would give us 40 inches.
The amplitude is 40/2
= 20
Hence,
f(x)=20cos(bx)+c
f(x)=20cos(bx)+32
if the curve takes 6 1/4 hours from low to high tides (9:15 am to 3:30 pm) then it will take 12 1/2 hours to complete a full cycle.
We make adjustments and convert
f(x) = 20 cos(375°) + 32
f(x) = 20 * 0.97 + 32
f(x) = 19.4 + 32
f(x) = 51.4

b. predict the daily sales of Fun Noodles if the price is $4.50
Answer: PART A:
The generic equation of the line is:
y-yo = m (x-xo)
First we look for the slope of the line:
m = (y2-y1) / (x2-x1)
m = ((5000) - (6000)) / (4-3)
m = -1000
Then, we substitute any point in the generic equation:
(xo, yo) = (4, 5000)
Substituting:
y-5000 = (- 1000) (x-4)
Rewriting:
y = -1000x + 4000 + 5000
y = -1000x + 9000
The equation is:
y = -1000x + 9000
PART B:
For the price of 3.50 we have:
y = -1000 * (3.5) +9000
y = 5500
