Answer:
See the attached figure which represents the problem.
As shown, AA₁ and BB₁ are the altitudes in acute △ABC.
△AA₁C is a right triangle at A₁
So, Cos x = adjacent/hypotenuse = A₁C/AC ⇒(1)
△BB₁C is a right triangle at B₁
So, Cos x = adjacent/hypotenuse = B₁C/BC ⇒(2)
From (1) and (2)
∴ A₁C/AC = B₁C/BC
using scissors method
∴ A₁C · BC = B₁C · AC
The value of X that will make this rational expression undefined would be if X = 0.
Answer:
y = 9x + 5
With y in dollars and x in hours.
Step-by-step explanation:
Bike-a-Rama charges $9 hourly for each of their bikes. And they have a fixed maintenance fee of $5.
The total cost of renting a bike, just like almost every business venture, would be given as
Total Cost = (Fixed Cost) + (Variable Cost)
Total Cost = y (the total absolute cost of renting a bike)
Fixed Cost = The compulsory maintenance cost for everyone that wants to rent = $5
Variable Cost = (Rent Rate given per hour) × (number of hours the bike is rented)
Rent rate given per hour = $9 per hour
Number of hours the Nike is rented = x
Variable Cost = $9x
Total Cost = y = 5 + 9x
So, y = $(9x + 5)
Hope this Helps!!!
