What type of conic section is the following equation? x2 + (y - 5)2 = 12

1 answer:

7 0

Short answer: It's a circle.
Argument
A parabola has a power of x on one side of the equal sign.

A circle (like this one) has variables raised to the second degree (x and y). The number in front of x^2 and y^2 is equal, usually 1.

An ellipse has x^2 and y^2 present, the numbers in front of x^2 is different from the number in front of y^2

hyperbola has a minus sign between the x^ and y^2. or between the y^2 and x^2

These are the main characteristics of each. They are not the only ones.

Answer:

4 hours. 1 3/4 is about 2, and 2 1/4 rounds to 2. 1/4 would round to 0, but it would not affect the estimate's accuracy much because we rounded up by 1/4 on 1 3/4 already. Philipe spent about 4 hours on activities.
