A satellite which travels around the earth has a power supply that provides power according to the formula: P =(17200)/(t + 100) where t is the number of days the satellite is aloft. Find the rate at which power is decreasing after 380 days. rate in watts...

Given s = 4t + 11t3, find the velocity when t = 1 s. velocity in m/s = My Answer: S'=4+33t^2 =4+33 =4+33 =37 velocity in m/s = 37 Can you please confirm this is correct. Thank you

Given s = 10 - 10t2 + 45t3, determine the velocity when t = 1 s. velocity in m/s = My Answer S'= 0-20t + 135t^2 S'(1) = -20+135 = 115 velocity in m/s = 115 Can you please confirm this is correct. Thanks!

A rifle bullet is fired directly upward from the ground. Its height above the ground at any instant of time t is given by the formula, s = 63t - 9.8t2. Assuming there is no air resistance how high will the bullet rise? height in meters = My Answer S'= 63-...

Given v = 4t - 9t3, find the acceleration when t = 1 s. acceleration in m/s2 = My Answer V'=4-27t2 V"= -54t V"(1)= -54 acceleration in m/s2 = positive 54 Can you please confirm this is correct???? Thanks

Given v = 2t3 + 87t2 - 636, determine the acceleration for t= 1 s. acceleration in m/s2 = My Answer v'= 6t^2+174t V"= 12t V"(1) = 12 acceleration in m/s2 = 12 Can you please confirm this is correct.. Thanks!

Bella, did you post this answer in the wrong question????

its actually 10...
