Write the equation of the circle with center (-4, 8) and passes through the point (-2, -1)

anzhelika [568]

Answer:

$(x+4)^2+(y-8)^2=85$

Step-by-step explanation:

The standard equation for a circle is given by:

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

Where (h, k) is the center and r is the radius.

We know that the center is (-4, 8). So, substitute -4 for h and 8 for k:

$(x-(-4))^2+(y-8)^2=r^2\\$

Simplify:

$(x+4)^2+(y-8)^2=r^2$

Now, we will need to find r.

We know that it passes through the point (-2, -1). So, we can substitute -2 for x and -1 for y and solve for r. So:

$(-2+4)^2+(-1-8)^2=r^2$

Evaluate:

$(2)^2+(-9)^2=r^2$

Square:

$4+81=r^2$

Add:

$r^2=85$

So, r squared is 85.

We don’t actually have to solve for r itself, since we will have to square it anyways.

So, we have:

$(x+4)^2+(y-8)^2=r^2$

Substituting 85 for r squared, we get:

$(x+4)^2+(y-8)^2=85$

And we have our equation.

There are 3 consecutive integers that sum to 15

scoundrel [369]

Consecutive integers are 1 apart
they are
x,x+1,x+2
add to 15
x+x+1+x+2=15
3x+3=15
minus 3 both sides
3x=12
divide both sides by 3
x=4
x+1=5
x+2=6

they are 4,5,6

dan and cheryl paddled their canoe 40 mi in 5 hr with the current and 16 mi in 8 hr against the current. Find the speed of the c

Arada [10]

Let the speed of the current be x and the speed of the canoe in still water be y, then

$y+x= \frac{40}{5} =8 \\ y-x= \frac{16}{8} =2$

Adding the two equations, we have:

$2y=10 \\ \\ \Rightarrow y=5$

From any of the equations, we have that x = 2

Therefore, the speed of the current is 2 miles per hour while the speed of the canoe in still water is 5 miles per hour.
