Circle P is tangent to the x-axis and the y-axis. If the coordinates of the center are (r, r), find the equation of the line con
almond37 [142]

Answer:

y=-x+r

Step-by-step explanation:

we know that

The tangency point on the x-axis is  (r,0)

The tangency point on the y-axis is  (0,r)

Find the slope of the line containing the points of tangency

m=\frac{0-r}{r-0}=-1

Remember that the equation of the line into slope intercept form is equal to

y=mx+b

where

m is the slope

b is the y-coordinate of the y-intercept

In this problem we have

m=-1

b=r

substitute

y=-x+r

Use Pythagorean Theorem to solve for x.<br><br> HELP ME PLZZZZ!!!! ASAP
4vir4ik [10]

Answer: 2\sqrt{22}

Step-by-step explanation:

Pythagorean theorem: a^{2} +b^{2} = c^{2}, where a and b are the legs and c is the hypotenuse.

We can solve for x by only using the left side of the triangle. Since we're only using the left side of the triangle, we can reduce 18 by 2 to get 9. Now we plug in our information to the equation.

9^{2} +b^{2} = 13^{2}

81 +b^{2} = 169

Since we don't know what b^{2} is, we're going to isolate it by subtracting 81 on both sides

b^{2} = 88

We have to square root both sides in order to find out b (or x in the problem).

\sqrt{b^{2}} = \sqrt{88}

When you put this on a calculator it would result in 2\sqrt{22} which is the answer d in the problem.

The explicit formula for a sequence is
Alexandra [31]

Answer:

28

Step-by-step explanation:

Let n = 21, and evaluate the expression.

a_n = -2 + \dfrac{3}{2}(n - 1)

a_{21} = -2 + \dfrac{3}{2}(21 - 1)

a_{21} = -2 + \dfrac{3}{2}(20)

a_{21} = -2 + \dfrac{3}{1}(10)

a_{21} = -2 + 30

a_{21} = 28
