Answer:

Explanation is the answer

Step-by-step explanation:

The max happens at the vertex. The line of symmetry runs through the vertex. So if you have the x-intercepts of the graph, the axis of symmetry will be the same distance from them but on opposite sides of the axis of symmetry. So if you have the x-intercepts then you can average them to fnd the x-coordinate of the middle point, the vertex.

So your factored form says the x-intercepts are (20,0) and (100,0).

So the x-coordinate of the vertex is (20+100)/2=120/2=60.

The question is asking for x-coordinate of the vertex so we are done.

What is the surface area of the cylinder?<br> 180pi ft2<br> 192pi ft2<br> 252pi ft2<br> 396pi ft2

butalik [34]

$\sf \longrightarrow \: \:Surface \: area \: of \: cylinder \: = \: 2\pi \: r \: h \: + \: 2\pi \: {r}^{2}$

r represents radius of cylinder

h represents height of cylinder

$\sf \longrightarrow \: \: r \: = \: \frac{Diameter}{2} \\$

$\sf \longrightarrow \: \: r \: = \: \frac{12}{2} \\$

$\sf \longrightarrow \: \: r \: = \: \cancel\frac{12}{2} \: \: ^{6} \\$

$\sf \longrightarrow \: \: r \: = \:6 \: ft$

$\sf \longrightarrow \: \: h \: = \: 15 \: ft$

<h3>Now , Substuting the values</h3>

$\sf \implies \: \:2 \: \times \: \pi \times \: 6 \: \times \: 15 \: \: + \: \: 2 \: \times \: \pi \times \: {6}^{2}$

$\sf \implies \: \:2 \: \times \: \pi \times \: 90 \: \: + \: \: 2 \: \times \: \pi \times \: 36$

$\sf \implies \: \:180 \: \pi \: + \: \: 72 \: \pi$

$\sf \implies \: \:252 \: \pi$

Hence, the surface area of cylinder is 252 π ft²
