Let the volume of the cylinder be V cubic meters, the diameter be d meters and the height be h meters.
Now we can write the formula for the volume as follows:
V=\pi\frac{d^{2}}{4}h
Rearranging the formula, the height becomes:
\large h=\frac{4V}{\pi d^{2}}

s below which does not belong? motivation self confidence positive attitude coordination conscientiousness
Alenkinab [10]
I would say that coordination doesn't belong. The other words seem to do with a person's personality or mentality, while coordination is more of a physical ability.

Given h (t) = negative 2 (t + 5) squared + 4, find h (negative 8)
kaheart [24]

Answer:

h(-8)= -14

Step-by-step explanation:

h(-8)= -2(-8 + 5)^2  + 4

h(-8)= -2(-3)^2  + 4

h(-8)= -2(9) + 4

h(-8)= -18 + 4

h(-8)= -14

What is the equation of a line that passes theough the points (-3,4) and (2,8)?​
Salsk061 [2.6K]
<h3><u>Explanation</u></h3>
  • Find the slope by using rise over run with two given coordinate points.

\begin{cases} (x_1,y_1)=(-3,4) \\ (x_2,y_2)=(2,8) \end{cases} \\ m =  \frac{y_2 - y_1}{x_2 - x_1}

  • Substitute the coordinate values in.

m =  \frac{8 - 4}{2 - ( - 3)}  \\ m =  \frac{4}{2 + 3}  \Longrightarrow \frac{4}{5}

We have got the value of slope. Substitute in the slope-intercept form.

  • Slope-Intercept

y = mx + b \\  \sf{m = slope}\\  \sf{b = y - intercept}

Substitute and Rewrite the equation.

y =  \frac{4}{5} x + b

  • Find the y-intercept or the value of b by substituting any given coordinate points.

I will substitute (2,8) in.

y =  \frac{4}{5} x + b \Longrightarrow \sf \small{Substitute \: \: the \:  \: coordinate \:  \: points \:  \: in \:  \: the \:  \: equation}

8 =  \frac{4}{5} (2) + b \\ 8 =  \frac{8}{5} + b \\ 40 = 8 + 5b \\ 40 - 8 = 5b \\ 32 = 5b \\  \frac{32}{5}  = b

Rewrite the equation by substituting the value of b.

y =  \frac{4}{5} x +  \frac{32}{5}

<h3><u>Answer</u></h3>

<u>\large \boxed{y =  \frac{4}{5} x +  \frac{32}{5} }</u>
