Here is a sketch of y=x^2+bx+c the curve intersects the x axis at (2,0) and point p the y axis at (0,-14) work out the x coordinate of the turning point of the graph (I've solved first part it's turning point I need)

the balance is found at the link

step-by-step explanation:

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
