Answer:
![y(x) = 0.0732x + 17.32](https://tex.z-dn.net/?f=y%28x%29%20%3D%200.0732x%20%2B%2017.32)
Step-by-step explanation:
The equation for the monthly charge has the following format
![y(x) = ax + b](https://tex.z-dn.net/?f=y%28x%29%20%3D%20ax%20%2B%20b)
In which y(x) is the cost in function of the number of kilowatt-hours used(x), a is the price of each killowatt hour and b is the fixed(base) charge.
Base charge of $17.32 per month.
This means that ![b = 17.32](https://tex.z-dn.net/?f=b%20%3D%2017.32)
charge of 7.32 cents per kilowatt-hour
Our answer is in dollars. Each dollar is 100 cents. So 7.32 cents is ![a = 0.0732](https://tex.z-dn.net/?f=a%20%3D%200.0732)
Write an equation for the monthly charge y in terms of x, the number of kilowatt-hours used.
![y(x) = ax + b](https://tex.z-dn.net/?f=y%28x%29%20%3D%20ax%20%2B%20b)
![y(x) = 0.0732x + 17.32](https://tex.z-dn.net/?f=y%28x%29%20%3D%200.0732x%20%2B%2017.32)
Answer:
precipitation then condensation
Step-by-step explanation:
Length / wingspan
14.8 / 9.8 = 0.5 / x
cross multiply
(14.8)(x) = (9.8)(0.5)
14.8x = 4.9
x = 4.9 / 14.8
x = 0.331 meters....wingspan of model
