Rose spent $27.50 at a parking garage in downtown Orlando. The garage charged a base fee of $5.50 for the first hour, and an hou

rly rate of $2.75 for each additional hour. The following sign is displayed to show the prices for the first 4 hours.
Part A: Create an equation that can be used to determine how many additional hours, ℎ, Rose parked her car in the garage.
Part B: Solve the equation to determine the number of additional hours, ℎ, Rose parked her car in the garage.

Answer:

A. 27.50 = 5.50 + 2.75h

B. 8 hours

C. 9 hours

Step-by-step explanation:

Total spent = $27.50

Base fee = $5.50

Hourly rate = $2.75

A. Create an equation that can be used to determine how many additional hours, ℎ, Rose parked her car in the garage

Total cost = fixed cost + variable cost

27.50 = 5.50 + 2.75h

B: Solve the equation to determine the number of additional hours, ℎ, Rose parked her car in the garage.

27.50 = 5.50 + 2.75h

Subtract 5.50 from both sides

27.50 - 5.50 = 5.50 - 5.50 + 2.75h

22 = 2.75h

Divide both sides by 2.75

h = 22/2.75

= 8

h = 8 hours

C: What is the total number of hours that Rose parked her car in the garage

Total number of hours = first hour + additional hours

= 1 + 8

= 9 hours

V(x)=x^2-25
Whitepunk [10]

Answer:

  -∞ < x < -5 ∪ -5 < x < -3/2 ∪ -3/2 < x < ∞

Step-by-step explanation:

The domain of any polynomial is "all real numbers." The domain of any rational function excludes any values of the variable that result in the denominator being 0. The function is "undefined" there.

__

  v(x)=\dfrac{x^2-25}{2x^2+13x+15}=\dfrac{(x+5)(x-5)}{(x+5)(2x+3)}\qquad x\notin \{-5,-\dfrac{3}{2}\}

The values x=-5 and x=-3/2 make the denominator of v(x) become 0, so those values are excluded from the domain of v(x). The function is "undefined" when its denominator is zero.

  -∞ < x < -5 ∪ -5 < x < -3/2 ∪ -3/2 < x < ∞

_____

<em>Additional comment</em>

The numerator and denominator factors (x+5) cancel each other, so there is no vertical asymptote at x=-5. Rather, the function has a "hole" there, where it is undefined. The limit as the function approaches x=-5 from either direction is v(x) = 10/7.
