What is the equation of a circle whose center is (2,0) and has a radius= 9?

Flauer [41]

The equation of a circle is: (x - h)² + (y - k)² = radius² where (h, k) is the center. Now just plug in your given information and simplify.

(x - 2)² + (y - 0)² = 9²

Your equation is:
(x - 2)² + y² = 81

Line segment XY is tangent to circle Z at point U. If the measure of is 84°, what is the measure of ? 42° 84° 96° 168°

Andreas93 [3]

Answer:

The measure of angle YUV is equal to $m$

Step-by-step explanation:

see the attached figure to better understand the problem

we have that

$arc\ UV=84\°$ -----> given problem

so

$m$ ------> by central angle

we know that

The triangle UZV is an isosceles triangle

because

$ZU=ZV=radius$

so

$m$ -----> bases angle of the isosceles triangle

Remember that

The sum of the internal angles of a triangle is equal to $180\°$

so

$m$

$2m$

substitute and solve for m<ZUV

$2m$

$m$

$m$ ------> by complementary angles

solve for m<YUZ

$48\°+m$

$m$

Upper AA 66-ft-tall fence runs parallel to a wall of a house at a distance of 3030 ft. Find the length of the shortest ladder t

Mkey [24]

Answer:

0.33 ft

Step-by-step explanation:

From the diagram, triangle ACE is similar to triangle BCD.

Therefore,

$\frac{b}{30+b} = \frac{6}{a}$

$a=\frac{6(30+b)}{b}$

Let the Length of the Ladder, L

Using Pythagoras theorem

$L^{2}=(30+b)^{2}+(\frac{6(30+b)}{b})^{2}$

$L^{2}=\frac{(30+b)^{2}(36+b^{2})}{b^{2}}$

$L=\sqrt{\frac{(30+b)^{2}(36+b^{2})}{b^{2}} }$

$L=\frac{30+b}{b}\sqrt{b^2+36}$

To find the least value, we have to equate the derivative of L to 0.

$L^{1}=\frac{b^{3}-1080}{b^{2}\sqrt{b^2+36}}$

Therefore:

b³-1080=0

b³=1080

b=10.26

The minimum length of the ladder is:

$L=\frac{30+10.26}{10.26}\sqrt{10.26^2+36}$

=0.33 ft
