So for a you need to add up all the numbers and for b you need to multiply all the numbers
Can you help me I posted a new question that is worth 50 points
Answer:
They will not have the same weight during the program
Step-by-step explanation:
Let x be the number of weeks.
<u>Sandra:</u>
Sandra is starting at 150 pounds and plans to lose 1 pound a week.
Weight after x weeks:
<u>Bernice:</u>
Bernice is starting at 135 pounds and plans to lose 1/2 a pound a week.
Weight after x weeks:
Weights must be the same, so
Since 30 weeks is more that 12 weeks (the duration of the program), they will not have the same weight during this program.
You devide 702 by 18 then devide 136.15 by 39, and it equals $3.49 each
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>
