A particle is moving along the curve y = x √ x, x ≥ 0. At time t its coordinates are (x(t), y(t)). Find the points on the curve, if any, at which both coordinates are changing at the same rate.please

Trig derivative? f(x)=6arctan(7e^x)

if f(x)=6arctan(7e^x) then how do you find the derivative? please help-e^x/(7e^2x/6+1/42) Go to ref 1 and click on show steps-ans: 42e^x/(1 + 49e^2x) d(f(x)/dx=d(6arctan(7e^x))/d(7e^x)xd(7e^x)/dx=6/(

A probability experiment is conducted in which the sample space of the experiment

is s = {1,2,3,4,5,6,7,8,9,10,11,12}. let event E = {2,3,4,5,6,7}, event F = {5,6,7,8,9}, event G= {9,10,11,12}, and event H = {2,3,4}. Assume that each outcome is equally likely. Find P(F or G) by c

Could you geniuses please help me with this maths question

The question is: Rearange this formula to make v the subject.u + v = uvfThank you!-well then lets seeuvf - v = u so that v ( uf - 1 ) = u therefore v = u / ( uf - 1 ) Good answer - eh?-How about... u

Solve the definite Integral

1 ∫ -1e^-iπx dx=? can someone please solve this? step by step solution please someone. thanks. thanks much!-∫(x = -1 to 1) e^(-iπx) dx = (1/(-iπ)) e^(-iπx) {for x = -1 to 1} = (1/(iπ)) [e^(iπ) - e^(

A standard deck of cards contains 52 cards. One card is randomly selected from the deck.

How would I compute the probability of randomly selecting a heart or club from a deck of cards?-You have 13 of heart and 13 of club in the deck. = 26 26 chances out of 52 = 26/52= 1/2-You take the am

How to solve 8 to the power of 6 divided by 6 to the power of 2

take 8 to the power of 6 and solve it then take 6 to the power of 2 and solve it then do your dividing (:-(8^6)/(6^2) = ((8^5)*8)/(4*9) = ((8^5)*2)/9 = 65,536/9
