3 inches would be the answer to your question. This is because area is length x width. 1 x 3= 3

Find the length of side Y (this is from the geometry for enjoyment and challenge textbook) PLEASE ANSWER ASAP IT'S DUE TOMORROW!
Ymorist [56]

Answer:

y= 3

Step-by-step explanation:

The triangle on the left is a right triangle, so we can use trig functions to solve for the missing side, y.

First, find the length of the side that both triangles are connected to.

tan30=x/9

Isolate the x variable and solve.

9(tan30)=x

x= 5.19615

Now use the Pythagorean Theorem to solve for the side length, y.

a^2+ b^2 = c^2

(5.19615)^2+ b^2= 6^2

c= 3

an equation of a circle is x2 + y2 + 10x – 6y + 18 = 0. . . . A.Show all your work in determining the center and radius of this
MariettaO [177]

A circle is a set of points in a plane equidistant from a fixed point. It has a general formula of x² + y² = r². This is if the center is at the origin. However, if the center at point h and k, the equation becomes (x-h)² + (y-k)² = r².<span>

We write the given equation in the form (x-h)² + (y-k)² = r² by completing the square.
</span>

<span>x</span>²<span> + y</span>²<span> + 10x – 6y + 18 = 0</span>

<span> (x² + 10x + 25 )+ (y² - 6y + 9) = −18 + 25 + 9 = 16
(x + 5)² + (y + 3)² = (4)²

Therefore,

center = (-5, -5)
radius = 4</span>

Will mark brainliest
FinnZ [79.3K]

Answer:

Yes and SSS

Step-by-step explanation:

Let’s write down the ratios to figure out the first question:

RP:MN=5:3

NP:ML=10:6

RN:LN=15:9

Notice that we can simplify all of those ratios to 5:3. That means that the sides are all similar, so yes, the triangles are similar.

For the second question: They are similar by because all sides are similar in the same ratio. That means that they are similar by the SSS similarity.

Hope that helps

Find the domain and range
almond37 [142]

Answer:

See answer above.

Step-by-step explanation:

These are the ordered pairs on the graph: (-2, 5), (2, 3), (-3, -2), (0, -5), (3, -6)

The domain is the first point in teach ordered pair and the range is the second number in the ordered pair.

So the domain is {-2, 2 , -3, 0, 3}

Range is {5, 3, -2, -5, -6}
