True or False. 1. Integral calculus- is concerned with calculating areas bounded by curves, volumes bounded by surfaces, and solutions to differential equations 2. The derivative of a function represents the slope of a normal line at any point on the curve.

Examine each function for relative extrema. What does relative extrema mean?   (A) f(x,y)=−x^2−2y^2 (B) g(x,y)=(x−1)^2 +y^2 (C) h(x,y)= x^3/3 −xy

Average Birth Height of Boys Using data collected at Kaiser Hospital, pediatricians estimate that the average height of male children changes at the rate of 52.8706e-0.3277t h'(t) = (1 + 2.449e-0.3277t2 inches/year, where the child's height h(t) is measured in inches and t, the child's age, is measured in years, with t = 0 corresponding to birth. Find an expression h(t) for the average height of a boy at age t if the height at birth of an average child is 19.4 in. (Round all coefficients to 3 decimal places.) h(t) = What is the height of an average 6-year-old boy? (Round your answer to two decimal places.) in

Please help me! I dont understand this.
