A particle moves on the circle x2 y2=25 in the xy-plane for time t≥0. At the time when the particle is at the point (3,4), dxdt=

stiks02 [169]

The movement of the particle on the circle is its displacement.

The value of dy/dt at this time is -9/2.

<h3>What is the differentiation?</h3>

Differentiation is a process, in Maths, where we find the instantaneous rate of change in function based on one of its variables.

A particle moves on the circle x^2 + y^2=25 in the XY-plane for time t≥0. At the time when the particle is at the point (3,4), dxdt=6.

The equation of the circle is given as:

$\rm x^2 + y^2=25$

Differentiate with respect to time

$\rm 2x \times \dfrac{dx}{dt}+2y \times \dfrac{dy}{dt}=0$

Substitute all the values in the equation

$\rm 2x \times \dfrac{dx}{dt}+2y \times \dfrac{dy}{dt}=0\\\\2(3) \times 6+2(4)\times \dfrac{dy}{dt}=0\\\\ 6 \times 6+8 \times \dfrac{dy}{dt}=0\\\\ 36+8\times \dfrac{dy}{dt}=0\\\\ 8\times \dfrac{dy}{dt}=-36\\\\ \dfrac{dy}{dt}= \dfrac{-36}{8}\\\\ \dfrac{dy}{dt}= \dfrac{-9}{2}$

Hence, the value of dy/dt at this time is -9/2.

3. Considering the following two-way frequency table:

tensa zangetsu [6.8K]

Answer:

41%

Step-by-step explanation:

It is 41% because it says 0.41 people like math and converting decimals to percents it would be 41% because 0.41 is decimal form for 41%

18x3=8(x+16)+10x Can someone please help me

quester [9]

Ok so 18x3=8x+128+10x (multiply the 8 with the stuff in the parenthesis) now you combine like terms so 54 = 128+18x now you have to get the numbers together so you subtract 128 ~> -74 = 18x then you divide -74/18 which is about -4.1 so x= -4.1
