The equation of the circle whose center is at the origin and whose diameter is 12.5 is x²+y²=39.0625

<h3>Equation of a circle</h3>

The formula for finding the equation of a circle is expressed as:

(x-a)² + (y - b)² = r²

where

(a, b) is the centre

r is the radius

Given the following

(a, b) = (0, 0)

r = 12.5/2 = 6.25

Substitute

(x-0)² + (y - 0)² = 6.25²

x²+y²=39.0625

Hence the equation of the circle whose center is at the origin and whose diameter is 12.5 is x²+y²=39.0625

Answer:

Question 6: -8

Question 7: C

Step-by-step explanation:

Question 6:

The reason question 6 is -8 is because of the distance in between each number, e.g -7 and -15. This is not to be confused with + 8 each time that would make the sequence 9, 18, 27.

Question 7:

The way we solve this question is using the nth term rule, whatever is before the n is the times tables we follow. So if it is 2n the sequence would be 2, 4, 6, 8 etc. However when we add something like the -2 we do the 2 times tables but this time we -2 for each one. Example: 2 - 2 = 0 so the first number of the sequence is 0, Example 2: 4-2 = 2 so the second number of the sequence is 2.

Write the coordinates of the vertices after a reflection across the line y = 2.
rewona [7]

P' =  (-1, 8)  (the x coordinate stays the same and the y coordinate =  (distance between -4 and 2)  + 2 =  6+2 = 8).

using the same  process:-

Q' = (4, 8)

R' =  (8, 5)

S' = (3, 5)

lapo4ka [179]

Answer:

The answer would be 3.606, but rounded is 3.61, or 3.6

Step-by-step explanation: A^2+B^2 = c^2, so 3x3=9

2x2=4,

9+4=13

Then square 13, which would give you 3.606
