Give the equation of the circle whose center is (5 -3) and goes through (2 5)

Alekssandra [29.7K]

Answer:

Step-by-step explanation:

The standard form for the equation of a circle is

$(x-h)^2+(y-k)^2=r^2$

From the info given, we have the center, (h, k) as (5, -3) and the x and y coordinates of (2, 5). We will use these to solve for r-squared, then plug back in what we need to write the equation.

$(2-5)^2+(5-(-3))^2=r^2$ which simplifies to

$(-3)^2+(8)^2=r^2$ and

$9+64=r^2$ so

$r^2=73$

Filling in the equation:

$(x-5)^2+(y+3)^2=73$

Reorder the numbers and combine like terms to simplify. 4.5 + 2 1/2 + 6.0 - 5 1/2

DanielleElmas [232]

Answer: B

Step-by-step explanation:

4.5+6=10.5

2 1/2 - 5 1/2 = 2.5 - 5.5 = -3

10.5 - 3 = 7.5

Two boats traveling toward a lighthouse that is 20o ft above sea level at its top. When the 2 boats and the lighthouse are colli

masha68 [24]

Answer:

The measure of x= $11.35^{\circ}$

Step-by-step explanation:

We are given that

Height of tower=200ft

Distance between two boats=250 ft

From given figure

$\frac{perpendicular\;side}{base}=tan\theta$

$\frac{200}{base}=tan15^{\circ}$

$base=\frac{200}{tan15^{\circ}}=746.55 ft$

Again ,

$\frac{200}{746.55+250}=tan x$

$\frac{200}{996.55}=tan x$

$x=tan^{-1}(0.20069)=11.35^{\circ}$

Hence, the measure of x= $11.35^{\circ}$
