Answer:
Y= -5/2x+3
Step-by-step explanation:
A perpendicular slope is always opposite (meaning if the original is negative, then it is positive and vice versa) and reciprocal (meaning the numerator and denominator of the original are flipped).
The y intercept I found by applying the slope to the point given.
Answer/Step-by-step explanation:
Factor this. GCF=2
2(2cos2x+cos x-1)=0
2(2cos x -1)(cos x+1)=0 Set each factor equal to zero and solve
2cos x -1=0 Add 1 to both sides
2cos x =1 Divide by 2
cos x =1/2
x=π/3
x=5π/3
cos x+1=0 Subtract 1 from both sides
cos x=-1
<u><em>x = π</em></u>

Answer: 750 miles
Step-by-step explanation:
The gas mileage is 75 miles per 1/2 gallon of gasoline.
First find how many miles it can go on 1 gallon of gasoline:
= 75 ÷ 1/2
= 150 miles
If the scooter can go 150 miles on 1 gallon, the number of miles it will go on 5 gallons is:
= 5 * 150
= 750 miles
