Complete Question:

The profile of a dam is modeled by the equation y = 24 (StartFraction x Over 10 EndFraction) squared, where x represents horizontal distance and y represents height, both in meters.

Point Z is at a horizontal distance of 15 meters from the left-most point of the dam. What is the height of the dam at point Z?

Answer:

The height is 36 meters

Step-by-step explanation:

Given

$y = 24 * \frac{x}{10}$

Required

The interpretation of the question is to determine the value of y when x = 15

Substitute 15 for x in: $y = 24 * \frac{x}{10}$

$y = 24 * \frac{15}{10}$

$y = 24 * 1.5$

$y = 36$

<em>The height is 36 meters</em>

Evaluate the integral by changing to polar coordinatesye^x dA, where R is in the first quadrant enclosed by the circle x^2+y^2=2

$\displaystyle\iint_Rye^x\,\mathrm dA=\int_{\theta=0}^{\theta=\pi/2}\int_{r=0}^{r=5}r^2\sin\theta e^{r\cos\theta}\,\mathrm dr\,\mathrm d\theta$

which follows from the usual change of coordinates via

$\begin{cases}\mathbf x(r,\theta)=r\cos\theta\\\mathbf y(r,\theta)=r\sin\theta\end{cases}$

and Jacobian determinant

$|\det J|=\left|\begin{vmatrix}\mathbf x_r&\mathbf x_\theta\\\mathbf y_r&\mathbf y_\theta\end{vmatrix}\right|=|r|$

Swap the order, so that the integral is

$\displaystyle\int_{r=0}^{r=5}\int_{\theta=0}^{\theta=\pi/2}r^2\sin\theta e^{r\cos\theta}\,\mathrm d\theta\,\mathrm dr$

and now let $\sigma=r\cos\theta$ , so that $\mathrm d\sigma=-r\sin\theta$ . Now, you have

$\displaystyle\int_{r=0}^{r=5}\int_{\sigma=0}^{\sigma=r}re^\sigma\,\mathrm d\sigma\,\mathrm dr=\int_{r=0}^{r=5}r(e^r-1)\,\mathrm dr=4e^5-\dfrac{23}2$

F-20f=21 what’s the answer

Virty [35]

$\bold{[ \ Answer \ ]}$

$\boxed{\bold{F \ = \ -\frac{21}{19} }}$

$\bold{[ \ Explanation \ ]}$

$\bold{Solve: \ f \ - \ 20f \ = \ 21}$

-----------------------------------

$\bold{Add \ Similar \ Elements:f-20f=-19f}$

$\bold{-19f=21}$

$\bold{Divide \ Both \ Sides \ By \ -19}$

$\bold{\frac{-19f}{-19}=\frac{21}{-19}}$

$\bold{Simplify}$

$\bold{F \ = \ -\frac{21}{19}}$

$\boxed{\bold{[] \ Eclipsed \ []}}$

Answer:

P-E-M-D-A-S

Step-by-step explanation:

Ok, so start with what i call "P-E-M-D-A-S"

P: parentheses | Also known as these: ( )

E: exponents | Its a small number by another number, like the 3 on your screen

M: Multiply | Also Known as x or a dot

D: Divide | i forgot how to make it

A: Add | also known as +

S: Subtract | also known as -

now go in order to solve it, it makes it much more easy!
