The number of bacteria in a refrigerated food is given by the function N(T) = 5T^2 – 10T + 100, where T is the temperature of the food in degrees Celcius. At what temperature will the number of bacteria be minimal? Temperature = degrees Celcius Find this minimal number of bacteria. Minimum number of bacteria =

The number of revolutions of two pulleys is inversely proportional to their diameters. if a 24-inch diameter pulley making 400 revolutions per minute is belted to an 8-inch diameter pulley, find the number of revolutions per minute of the smaller pulley.

Will give are given that xy is parallel to zw. if xz is a transversal that intercepts xy and zw, angle angle alternate interior angles. since xy is parallel to zw, we know that these angles are we also know that angle xvy and angle zvw are , and thus congruent. we can conclude that △xyv ~ △zwv using the similarity theorem.

What is x and y intercepts for y=x+7
