hello :<span>
<span>an equation of the circle Center at the
A(a,b) and ridus : r is :
(x-a)² +(y-b)² = r²
in this exercice : a =4 and b = -1 (Center at the origin)
r = AP.... P(0.1)
r² = (AP)²
r² = (4-0)² +(-1-1)² = 16+4=20
an equation of the circle that satisfies the stated conditions.
Center at A(4,-1), passing through P(0, 1) is : </span></span>(x-4)² +(y+1)² = 20
Answer:
111.8 yards
Step-by-step explanation:
So by walking diagonally across the field, Patrick is making a right triangle with his path (the two legs are the width and length of the field). Let a = 50, b = 100, and c = the distance Patrick walks.
For a right triangle, we use the Pythagorean Theorem: a² + b² = c²
Since you're finding c, we can rearrange (using algebra) to get: 
Fill in the values for a and b:
= 111.8 yards.

2 1/4 c. 2 Tablespoon 1 1/5 teaspoon fruit (or make it easy and take out 1/5 teaspoon fruit to just leave 1 teaspoon fruit)
1 1/5 teaspoon butter.
F(1) = 7
f(2) = 7 + 6 = 13
Recursive formula => f(n + 1) = f(n) + 6
Next term = 31 + 6 = 37.
