gas is pumped into a spherical balloon at the rate of 1 cubic feet per minute. How fast is the diameter of the balloon increasing when the balloo0n contains 36 cubic feet of gas?

an 8ft 2 by 4 is leaning against a 10ft wall. THe lower end of the 2 by 4 is pulled away from the wall at the rate of 1ft/sec. How fast is the top of the 2 by 4 moving toward the ground (a) when it is 5 ft from the ground and (b) when it is 4 ft from the...

a woman on a dock is using a rope to pull in a canoe. the rope is pulled at the rate of 2 ft/sec, 3ft above the point level with the connection of the rope to the canoe. How fast is the canoe approaching the dock when the length of the rope from her hands...

Wade works at the candy shop. He wrapped 56 prices of fudge to sell. How may total pounds of fudge did he wrap if each piece weighed 1 ounce

simply chart it out. f(x) g(x) f'(x) g'(x) 2| -3 4 -2 7 then plug them into the equations. A. (5)-3 - 4(4) -15 - 16 = -31 B. (-3)4 = -12 C. -3/4 D. 4/1-3 = 4/-2 = -2

well the chart didn show up right but when x = 2 then f(x) = -3 g(x) = 4 f'(x) = -2 g'(x) = 7 then plug them into the equations. A. (5)-3 - 4(4) -15 - 16 = -31 B. (-3)4 = -12 C. -3/4 D. 4/1-3 = 4/-2 = -2

f'(x) = secxtanx then use the product rule and figure out the derivative of that: f''(x) = tanxsecxtanx + secx sec^2x and then it becomes tan^2x + sec^3x. then you plug in pi/4 which is 45 degrees. it is (1)(1.41) + 2.83 and the answer is 4.24

Thanks Darling.
