Answer:
8 hours
Step-by-step explanation:
Let t hours be the time needed Sonya to catch up Brianna.
Sonya:
Time = t hours
Rate = 44.8 mph
Distance miles
Brianna
Time hours
Rate = 32 mph
Distance miles
Note that because Sonya must catch up Brianna.
Use formula
Hence,
Solve this equation:
Answer: He will pick up a signal from the transmitter 29.43 miles of the drive.
Step-by-step explanation:
Since we have given that
Radius = 29 mile
So, equation of circle would be
There is a straight line from a city 32 miles north i.e. (0,32) to a second city 40 miles east of the transmitter i.e. (40,0)
So, equation of line would be
So, we will put this value in the equation of circle.
So, x= 4.12 and x = 27.1
So, y = 28.7, y = 10.32
So, distance between them would be
Hence, he will pick up a signal from the transmitter 29.43 miles of the drive.
Answer:
-3,2
Step-by-step explanation:
Its the points on x axis
Start anywhere basically, just keep the line to where it will always continue at a constant value. Dont curve the line for example, that would make it unlinear.
