Uber is now charging a $2.50 flat rate in addition to $0.75 per mile for your ride. Janae can spend at most $13 on her Uber Ride
Alex777 [14]

Answer:

  • B: 10

Step-by-step explanation:

<u>Full charge can be expressed as equation:</u>

  • c = 2.5 + 0.75m, where c- charge, m- miles

<u>The limit for charge is $13, then we got inequality:</u>

  • 0.75m + 2.5 ≤ 13
  • 0.75m ≤ 9.5
  • m ≤ 9.5/0.75
  • m ≤ 12.66

Option B: 10 is correct as the only number satisfying the inequality

Which of the following functions have a vertical asymptote for values of Ø such that cos Ø = 1?Select all that apply.
igomit [66]

Answer:

y=\cot \theta and y=\csc \theta

Step-by-step explanation:

Note that if \cos \theta=1, then \sin \theta=0.

Functions y=\cos \theta,\ \ y=\sin \theta do not have vertical asymptotes at all.

Vertical asymptotes have functions y=\tan \theta,\ \ y=\cot \theta,\ \ y=\sec \theta,\ \ y=\csc \theta.

Functions y=\tan \theta and y=\sec \theta have the same vertical asymptotes (when \cos \theta =0).

Functions y=\cot \theta and y=\csc \theta have the same vertical asymptotes (when \sin \theta =0). See attached diagram
