The population of a city grows from an initial size of 400,000 to a size P given by P(t) = 400.000 + 5000t^2. where t is in years.

a) Find the growth rate. dP/dt.
b) Find the population after 10 yr.
c) Find the growth rate at t = 10.

Factor the expression using gcf 9b+45

In the diagram, points d and e are marked by drawing arcs of equal size centered at b such that the arcs intersect ba and bc. then, intersecting arcs of equal size are drawn centered at points d and e. point p is located at the intersection of these arcs. based on this construction, m , and m

You are standing next to a really big circular lake. you want to measure the diameter of the lake, but you don't want to have to swim across with a measuring tape! you decide to walk around the perimeter of the lake and measure its circumference, and find that it's 400\pi\text{ m}400? m. what is the diameter dd of the lake?
