Does the graph represent a function?

Harrizon [31]

Answer:

The graph does represent a function because it passes the vertical line test!

Step-by-step explanation:

A vertical line test means if you put a vertical line over any area on the graph it shouldn't hit the line more than once :)

HELP ASAP PLEASE AND SHOW WORK!!! Write the vertex form of the following equation. y= x^2+6x-5

valkas [14]

Answer:

<h3> $\boxed{\bold{y=(x+3)^2-14}}$ </h3>

Step-by-step explanation:

y= x²+6x-5

completing the square: a²+2ab+b² = (a+b)² where a²=x² (so a=x) and 2ab=6x (so b would be 3):

$y=x^2+6x-5\\\\y=\underline{x^2+2\cdot x\cdot3+3^2}-3^2-5\\\\y=(x+3)^2-9-5\\\\\underline{y=(x+3)^2-14}\\\\\\vertex:\ \ (-3,\,-14)$

if 1 gallon of paint covers 400 square feet, about how many gallons of paint are needed to paint the outside of a spherical tank

ollegr [7]

Given:
Diameter if the spherical tank = 20 ft.
Now,
We know,
radius = diameter / 2
= 20 / 2
= 10 ft.
Now,
The area of the spherical tank = $4 \pi r^{2}$

= $4 \pi (10)^{2}$

= $4 * \pi *100$

= $1256.637061$

= $1256.64~ft^2-->rounded$

Now,
According to the question,
400 ft² needs 1 gallon of paint
1 ft² needs (1 / 400) gallon of paint
1256.64 ft² needs (1 / 400) * 1256.64 gallon of paint
= 3.1416 gallon of paint
= 3.14 gallon of paint --------------> rounded

So, we need 3.14 gallon of paint
