Hey I tried, hope it helps... can't work it out, all the best
Answer:
me too a I don't understand
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 = -7 and b = -1 (Center at: A(-7,-1) )
r = AP.... P(8,7)
r² = (AP)²
r² = (8+7)² +(7+1)² =225+64=289 ...... so : r = 17
an equation of the circle that satisfies the stated conditions.
Center at </span></span>A(-7,-1), passing through P(8, 7) is :
(x+7)² +(y+1)² = 289
The point (-15,y ) <span>lies on this circle : (-15+7)² +(y+1)² = 289....(subsct : x= -15)
(y+1)² = 225
(y+1)² = 15²
y+1 = 15 or y+1 = -15
y = 14 or y = -16
you have two points : (-15,14) , (-15, -16)</span>
Answer:
$5.79 +
$0.95
Estamate
$5.80 +
$1.00
= $6.80
We only round one digit.
Step-by-step explanation:
180-92=88 the answer is 88 because a line is equal to 180 degrees and you got one angle equaling 92 degrees so you just subtract 180 minus 92, getting you angle 8 to be 88 degrees
