The equation of a circle is written as ( x-h)^2 + (y-k)^2 = r^2
h and k is the center point of the circle and r is the radius.
In the given equation (x+3)^2 + (y-1)^2 = 81
h = -3
k = 1
r^2 = 81
Take the square root of both sides:
r = 9
The center is (-3,1) and the radius is 9
A. 7.5 pages per hour B. $2.66 for one page
The distance formula is d=√(x2-x1)² + (y2-y1)²
So... d =8.06226
Hope this helps
Answer:
No I dont agree with Mai. As both the slug and snail are moving with constant speed.
Step-by-step explanation:
Given that:
A slug travels 3 centimeters in 3 seconds.
Speed of slug = distance/ time = 3/3 = 1 cms^-1
A slug travels 3 centimeters in 3 seconds.
Speed of snail = distance/ time = 6/6 = 1 cms^-1
Hence both have constant speeds only the time span for snail is increased which gives more distance it doesn't means that it had covered more distance.
i hope it will help you!
