<span>Distance = d miles ; rate = 60 mph ; time = d/60 hrs

distance = d miles ; rate = 50 mph ; time = d/50 hrs
----------------------
Round-trip DATA:
distance = 2d miles ; rate = 55 mph ; time = (2d)/55 hrs
-----------------------------------------------------------
Equation:

Roundtrip time - other time = -1/2 hr
(2d)/55 - [(d/60)+(d/50)] = -1/2
(2d)/55 - [(110d)/(50*60)] = -1/2
---
600(2d) - 11[110d] = -16500
1200d - 1210d = -16500
-10d = -16500
distance = 1650 miles

Hope this helped :)</span>

Which of the following are vertical asymptotes of the function y = 3cot(1/2x) - 4?
emmasim [6.3K]
A vertical asymptote is a line that the graph of the function does not cross.
If: \lim_{x \to a} 3 cot (1/2 x)-4 =  +/- ∞
then the line x = a is a vertical asymptote.
For x = 0:
f ( 0 ) = 3 * cot 0 - 4 = ∞
For x = +/- 2 π :
f ( 2 π ) =  3 * cot π - 4 = - ∞
Answer:
A ) x = 0  and C ) x = +/- 2π

-1/7(14+28p)-13=4(1/2p-3)-6p
Julli [10]

Answer:

No Solution

Step-by-step explanation:

<u>-1/7</u>(14+28p)-13=<u>4</u>(1/2p-3)-6p

-2-4p-13=2p-12-6p

rearrange the question so like terms are next to each other

<u>-2-13</u>-4p=<u>2p-6p</u>-12

-15-4p=-4p-12

add 12 to both sides

-3-4p=-4p

add 4p to both sides

-3=0

No solution
