Find the equation of the circle with a diameter whose end points are (-1,-2) and (-3,2)

Sergeeva-Olga [200]

Answer:

The equation of the circle with a diameter whose end points are (-1,-2) and (-3,2) is

$x^{2} +y^{2}+4x-1=0$

Step-by-step explanation:

Explanation:-

Step 1:-

The equation of the circle having center and radius is

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

here center is (h,k) and radius is r

Given diameter whose end points are (-1,-2) and (-3,2)

The diameter of the circle is passing through the center of the circle

so center of the circle = midpoint of two end points

$(\frac{-1 +(-3) }{2} ,\frac{-2+2 }{2} )$

$(-2,0)$

therefore center (h,k) = (-2,0)

Step 2:-

we have to find the radius of the circle

the radius of the circle = the distance from center to the one end point

i.e., C P = r

Given one end point is P(-3,2) and center C(-2,0)

The distance formula of two points are

$\sqrt{(x_{2}-x_{1} ) ^{2}+ (y_{2}-y_{1} ) ^{2}}$

$r=\sqrt{{(-3)-(-1) ) ^{2}+ (2-(-2)) ^{2}}$

$r=\sqrt{5}$

Step 3:-

center (h,k) = (-2,0) and

radius $r=\sqrt{5}$

The standard form of circle equation

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

$(x-(-2))^2+(y-0)^2=\sqrt{5} ^2$

on simplification is

$x^{2} +y^{2}+4 x-1=0$

What is the amplitude and period of f(t)=-cos t

Vadim26 [7]

Answer:

c. amplitude: 1; period: $2\pi$

Step-by-step explanation:

The given function is $f(t)=- \cos t$

This function is of the form;

$y=A \cos Bt$

where $|A|$ is the amplitude.

When we compare $f(t)=- \cos t$ to $y=A \cos Bt$ , we have

$A=-1$ , therefore the amplitude of the given cosine function is $|-1|=1$

The period is given by;

$T=\frac{2\pi}{|B|}$

Since B=1, the period is $T=\frac{2\pi}{|1|}=2\pi$

Please help and explain!! Will give brainliest!!

bearhunter [10]

So of you set it equal to each other
150m+3m = 9m
-3m = -3m
you get 150m=6m
and you divide by 6 on each side so it comes out to 25 minutes... I think...

What is the equation of the line with an x-intercept of -1 and a y-intercept of 2?

iragen [17]

Answer:

y = 2x + 2

Step-by-step explanation:

The general form

is;

y = mx + b

where m is the slope and b is the y-intercept

so we have;

y = mx + 2

To get m, substitute the point (-1,0)

So we have

0 = -m + 2

m = 2

So the equation is;

y = 2x + 2
