Answer:

$367.38 is the cost to stain the entire deck.

Step-by-step explanation:

Here is what you need to know beforehand:

<em>Diameter</em> is <u>a line</u> that goes <u>through a circle</u>. <em>Radius</em> is <u>a line </u>that goes from <u>the edge of the circle all the way to the center</u>/<u>a line </u>that goes <u>halfway through the circle</u>.

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

<u>First, find the area of the circle. Here is the formula:</u>

Area = 3.14 (Pi) x r²

Since radius is half of the diameter (as explained above), you'll need to divide the diameter in half: 12m/2 = 6m

So the formula will look like this:

Area = 3.14 x 6²

<u>Then, you just do the math:</u>

Area = 3.14 x 6²

Area = 3.14 x 36

Area = 113.04

The goal of the problem is to find the amount of money Emma needs. <u>Finally, all you need to do is multiply the amount it cost to stain per square meter by the total area of the deck:</u>

Answer = 113.04 x 3.25

Answer = 367.38

$367.38 is the cost to stain the entire deck.

To start, the equation has to be converted to slope-intercept form, or y=mx+b. Start by subtracting x from both sides; x-x+2y=4, 2y=4-x. Switch 4 and -x around to conform to the formula; 2y=-x+4. Then divide by 2 to isolate y; y=-\frac{1}{2}x+2. This is the final equation. Because the slope of a line perpendicular is always the opposite reciprocal (i.e. The opposite reciprocal of 4 is -\frac{1}{4}, the opposite reciprocal of -\frac{1}{5} is 5) the opposite reciprocal of -\frac{1}{2}  is 2. So the equation of the line is y=2x, and the answer is A.

(4x - 3) × (x + 2)=0
matrenka [14]

Hi,

AxB = 0 means A=0. or B=0

so 2 solutions :

4x-3= 0

4x=3

x = 3/4

and x+2 = 0.

x= -2

solutions are : -2 +and 3/4
