Answer:
<h3>(x+8)² + (y - 9)² = 100</h3>
Step-by-step explanation:
The general equation of a circle is expressed as;
(x-a)² + (y - b)² = r² where;
(a, b) is the centre of the circle
r is the radius
Given
Centre (-8, 9) where a = -8, b = 9
radius r = 10
Substitute into the formula to get the required equation;
(x-(-8))² + (y - 9)² = 10²
(x+8))² + (y - 9)² = 10²
(x+8)² + (y - 9)² = 100
Hence the required equation is (x+8)² + (y - 9)² = 100
1/6 of the muffins is 3 muffins with nuts. So you multiply 3 by 6 to get 18 muffins in all.
Answer:
She has 16 brownies
Step-by-step explanation:
Initially cut rectangular pan in to two halves.
Then cut each half in half again.
Now total pieces = 4
Now repeat cutting half on other side:
total pieces =8
Now divide each half into another half.
total pieces = 8 x 2 = 16
As can be shown in figure:
Black = first half
pink = dividing each half into another half.
