Answer:

If the circle shown (which I can't see) has a radius of 2, then it's equation 3, if the radius is 4, then it's equation 4.

Step-by-step explanation:

The equation for a circle is $(x-h)^{2} +(y-k)^{2} =r^{2}$

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

Find the value of k given that both points lie on a line passing through the origin.

Bond [772]

Answer:

$k=-3$

Step-by-step explanation:

Since the line passes through the origin, it must be a proportional/direct variation equation.

Direct variation equations have the form:

$y=ax$

Where a is the constant of proportionality.

Let’s solve for a. We know that when x=5, y=40. So:

$40=5a$

Divide both sides by 5:

$a=8$

Therefore, our equation is:

$y=8x$

We want to find the value of k such that y=-24. So, subsitute -24 for y and k for x:

$-24=8k$

Divide both sides by 8:

$k=-3$

Hence, the value of k is -3.

Slav-nsk [51]

The kite is approximately 78.80 feet off of the ground.

Explanation: If we assume that the string his held taut without any swag, we can use a right triangle to solve for the height of the kite. sin
