Prove or disprove that the point (√5, 12) is on the circle centered at the origin and containing the point (-13, 0). Show your w
pav-90 [236]

Using the equation of the circle, it is found that since it reaches an identity, the point (√5, 12) is on the circle.

<h3>What is the equation of a circle?</h3>

The equation of a circle of center (x_0, y_0) and radius r is given by:

(x - x_0)^2 + (y - y_0)^2 = r^2

In this problem, the circle is centered at the origin, hence (x_0, y_0) = (0,0).

The circle contains the point (-13,0), hence the radius is found as follows:

x^2 + y^2 = r^2

(-13)^2 + 0^2 = t^2

r^2 = 169

Hence the equation is:

x^2 + y^2 = 169

Then, we test if point (√5, 12) is on the circle:

x^2 + y^2 = 169

(\sqrt{5})^2 + 12^2 = 169

25 + 144 = 169

Which is an identity, hence point (√5, 12) is on the circle.

Can someone please help me solve this
AURORKA [14]

Answer:

1. 1.25

2. 0.8

Step-by-step explanation:

1. 2 : 2.5 = 1.25 Ratio from P To Q - 1 : 1.25

2. 2.5 : 2 = 0.8 Ratio from Q to P - 1 : 0.8

1. All you have to do is find the corresponding sides(meaning similar) and the compare them from one to another.

Example:

I know 5 and 4 are corresponding sides because they are similar. The ratio is Q to P we can find by writing them down. It can be written like this.

5:4 is so when we multiply this ratio from any side of Q we will get the correpoding side from P.

5:4 ratio = 1 : 0.8 - So the ratio is 0.8

There this is another ratio that we can compare to.

Now let’s say we need to find when the one of the P side is 4 and what would be the corresponding side.

4 x 1.25(ratio from P to Q) = 5

We can also find when the P side is 3 what would be Q’s corresponding side. Which is the ratio from P to Q or 1.25.

So just multiply 3 by 1.25.

3 x 1.25 = 3.75

3.75 x 0.8 = 3
