A point moves along the curve y = √ x in such a way that the y-component of the position of the point is increasing at a rate of

Eduardwww [97]

Answer:

The value of x component changes at a rate of $\frac{dx}{dt}=4\sqrt{x}$ units per second

Step-by-step explanation:

We are given that $y=x^{\frac{1}{2}}$

Differentiating on both sides with respect to time we get

$\frac{dy}{dt}=\frac{d\sqrt{x}}{dt}\\\\\frac{dy}{dt}=\frac{1}{2}x^{\frac{-1}{2}}(\frac{dx}{dt})\\\\\frac{dy}{dt}=\frac{1}{2\sqrt{x}}\frac{dx}{dt}$

It is given that $\frac{dy}{dt}=2units/sec$

Solving for $\frac{dx}{dt}$ we get

$\frac{dx}{dt}=\frac{dy}{dt}\times 2\sqrt{x}\\\\\frac{dx}{dt}=4\sqrt{x}$

Llana [10]

Minimal grade to barely pass would be a C, but you should review and go for at least a B or B+ if you want to pass with a C in the class as a whole.

9,220,000,000 in scientific notation

Roman55 [17]

Answer:

9.22×10^9

Step-by-step explanation:

The number must be written with

- a number between 1-10

- multiplied by a power of 10

The power of 10 tells you how many times you moved the decimal.

Reid gets on a Ferris Wheel from a platform 3 feet above the ground (which is the low point of the rotation). The diameter of th

Sati [7]

This corresponds to a sinusoidal graph, we have:

Radius= 20 feet, that corresponds to the amplitud (A)

One revolution takes 24 seconds, that corresponds to the period

Min= 3 feet

k=360/24=15

D= bottom distance+ amplitud=3+20=23 feet

$\begin{gathered} \text{The movement is represented by the expression:} \\ y=A\cos (kx)+D \end{gathered}$

Then, let x be the time, in seconds:

$y=20\cos (15x)+23$

a) To determine Reid's height after 1 minute= 60 seconds, substitute x=60

$\begin{gathered} y=20\cos (15\cdot60)+23 \\ y=9\text{ f}eet \end{gathered}$

b) To determine when Reid's height will first reach 18 feet, we have to substitute y=18 feet, and isolate x:

$\begin{gathered} 18=20\cos (15x)+23 \\ 18-23=20\cos (15x) \\ -5=20\cos (15x) \\ -\frac{5}{20}=\cos (15x) \\ -\frac{1}{4}=\cos (15x) \\ By\text{ trigonometric properties:} \\ 15x=\cos ^{-1}(-\frac{1}{4})+2\pi n \\ x=\frac{\cos^{-1}(-\frac{1}{4})}{15}+\frac{2\pi n}{15} \end{gathered}$
