Answer:
Pool B has the greater circumference.
Step-by-step explanation:
Pool A has a radius of 16 feet, and Pool B has a diameter of 9.94 meters.
We want to see which pool has a greater circumference.
The circumference of a circle is the distance around a circle or the total length of a circle, and it is given as:
where r = radius of the circle
So that our comparison can be accurate, let us put the dimensions of both pools in a single unit, metre.
The radius of pool A is 16 feet.
1 foot = 0.305 metres
16 feet = 4.88 metres
The radius of pool A in metres is 4.88 metres
CIRCUMFERENCE OF POOL A
CIRCUMFERENCE OF POOL B
As we can see, pool B has the greater circumference.
Answer:
y = -x - 1
Step-by-step explanation:
y = mx + b
m = slope
b = y-intercept
On the graph, the point on the y-axis is the y-intercept. That point is (0, -1). So the y-intercept is -1.
To find the slope, find two points and put it in the slope equation.
Point A: (0, -1)
Point B: (-1, 0)
m =
Point A:
Point B:
m =
m =
m = -1
y = -1x - 1
In other words, y = -x - 1
