I don’t have that In person so I don’t know how I could measure it, but I do know that you could use a ruler for this! Or use your Device to look up the act measure meant of I inch! Then maybe you will find it! If less than an inch look up the exact measurements of half an inch

mars1129 [50]

Answer:

36 milliliters of rain.

Step-by-step explanation:

The rate at which rain accumluated in a bucket is given by the function:

$r(t)=10t-t^2$

Where r(t) is measured in milliliters per minute.

We want to find the total accumulation of rain from <em>t</em> = 0 to <em>t</em> = 3.

We can use the Net Change Theorem. So, we will integrate function <em>r</em> from <em>t</em> = 0 to <em>t</em> = 3:

$\displaystyle \int_0^3r(t)\, dt$

Substitute:

$=\displaystyle \int_0^3 10t-t^2\, dt$

Integrate:

$\displaystyle =5t^2-\frac{1}{3}t^3\Big|_0^3$

Evaluate:

$\displaystyle =(5(3)^2-\frac{1}{3}(3)^3)-(5(0)^2-\frac{1}{3}(0)^3)=36\text{ milliliters}$

36 milliliters of rain accumulated in the bucket from time <em>t</em> = 0 to <em>t</em> = 3.

<u>Given</u><u> </u><u>:</u><u>-</u>

Line p has an equation of y = 5/3x - 4 .
Line q includes point (-10,-3) and is perpendicular to the line p .

<u>To </u><u>Find</u><u> </u><u>:</u><u>-</u>

The equation of line q .

<u>Solution</u><u> </u><u>:</u><u>-</u>

The equation of the line p is ,

$\sf\blue{\longrightarrow}$ y = 5/3x - 4

On comparing to slope intercept form of the line which is y = mx + c , we have ,

$\sf\blue{\longrightarrow}$ m = 5/3

Now as we know that the product of slopes of two perpendicular lines is -1 . So the slope of the perpendicular line will be ,

$\sf\blue{\longrightarrow} m_{\perp} = -3/5$

Now here the line q passes through the point (-10,-3) . So on using the point slope form of the line we get ,

$\sf\blue{\longrightarrow} y - y_1 = m(x-x_1)$

$\sf\blue{\longrightarrow}$ y - (-3) = -3/5[ x-(-10)]

$\sf\blue{\longrightarrow}$ y +3 = -3/5(x+10)

$\sf\blue{\longrightarrow}$ y+3 = -3/5x - 6

$\sf\blue{\longrightarrow}$ y +9 = -3/5x

$\sf\blue{\longrightarrow}$ y = - 3/5x - 9

<u>Hence</u><u> the</u><u> required</u><u> answer</u><u> is</u><u> </u><u>y </u><u>=</u><u> </u><u>-</u><u>3</u><u>/</u><u>5</u><u>x</u><u> </u><u>-</u><u> </u><u>9</u><u> </u><u>.</u>
