"<span>The volume of a cylinder with height h and radius r is given by the formula below. V = Πr 2 h Complete the equation below by writing an equation equivalent to height, h, of a cylinder.

Please, instead of "</span>V = Πr 2 h," type V = pi*r^2*h:  "pi times radius squared times h"
                                                                               V
This can be solved for the height of a cyl.:  h = ---------

Use " ^ " to denote exponentiation, please.

Describe and correct the error a student made in writing an exponential function
NemiM [27]

Answer:

we CANNOT DIVIDE 3 with 6.

Step-by-step explanation:

Here,as given in the question:

Starting value = 6

Constant ratio = 1/3

Now, exponential function is obtained by the product of starting value and the constant ratio repeatedly.

⇒ f(x) = (Starting value) x (ratio)... x times

\implies f(x) = 6 (\frac{1}{3} )^x =  6 (\frac{1}{3} )  (\frac{1}{3} )  (\frac{1}{3} )  .... x  

Now, we CANNOT DIVIDE 3 with 6 as it is in the power of x.

Hence, \implies f(x) = 6 (\frac{1}{3} )^x and f(x)  \neq 2^x

A boat heads north across a river at a rate of 2 miles per hour. If the current is flow A boat heads north across a river at a r
Ivahew [28]

Answer:

\textrm{Resultant velocity}\ =\ \sqrt{29}\ miles/hour

along the direction 68.19° from north.

Step-by-step explanation:

Given,

  • speed of the boat, u= 2 miles/hour along north
  • speed of the river, v= 5 miles/ hour along east

Since, north and east are perpendicular to each other, so we can write the resultant velocity in vector form as,

\vec{r}\ =\ 2\hat{i}+5\hat{j}

Hence, the magnitude of resultant velocity can be written as

r\ =\ \sqrt{2^2+5^2}

  =\ \sqrt{4+25}

  =\ \sqrt{29}

Hence, the magnitude of resultant vector is \sqrt{29} moles/hour.

And the direction of the boat can be given by,

tan\theta\ =\ \dfrac{5}{2}

=>\ tan\theta\ =\ 2.5

=>\ \theta\ =\ tan^{-1}2.5

                 = 68.19°

Hence, the resultant velocity of boat is \sqrt{29} miles/hour along the direction making an angle 68.19° with the north.
