Answer:
radius = 
Step-by-step explanation:
The radius of the circle is the distance from the centre to a point on the circumference.
Calculate the radius using the distance formula
r = √(x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (- 7, - 4)
r = 
= 
=
Answer:
The difference between the shortest and longest fish is 12 inches.

Answer:
q = ± 
Step-by-step explanation:
We are to solve for q in:
16pq² = 25
q² = 
= ±
= ±
That's already in gradient-intercept form, EXCEPT that we typically write such an equation with y positive.
So we'd geet y = -x - 1 (answer)
Note that "gradient" means "slope" here. The slope is -1 and the y-intercept is also -1.
a point because a point has zero dimensions. there's no length, height, width, or volume. its only property is its location. you could have a collection of points, such as the endpoints of a line or the corners of a square, but it would still be a zero-dimensional object.
