Need help with 2 math problems. View screenshot below for problems.

The traffic flow rate (cars per hour) across an intersection is T(t) = 400 + 1000t 120t2, where t is in hours, and t=0 is 6am. How many cars pass through the intersection between 6 am and 11 am? No w An c 1 2 3 4 5 0 To find the blue shaded area above, we would calculate: [ f(z)da = area The limits of integration are: a = , b = The integrand is: f(x) The value of the integral is: [ fla)da = (Round to two decimal places)
