2.25
Step-by-step explanation:
5 3/4 − 3 1/2 = 2.25

The diameter is 12 units long. Their equation could be seen in y = 1, because it is a horizontal line. From x = - 7 to x = 0 is 7 units. From x = 0 to x = 5, is 5 units. 5 + 7 = 12. This means the radius is 6. We will use this later. If you need another way to find the radius, let me know. I can just use distance formula.
We will use these endpoints to find the center.
Midpoint =

=

=

= (- 1, 1)
This is the center.
The equation of a circle is (x - h)² + (y - k)² = radius² where (h, k) is the center.
Plug in our given information now.
(x + 1)² + (y - 1)² = 6²
(x + 1)² + (y - 1)² = 36 is your equation.
Unlike terms I guess meaning a zero pair?
Answer: So we'll use trig to solve this because it's a right triangle. The hypotenuse is the ladder (h) and the two smaller sides are the ground and the vertical wall (w).
That angle ladder makes with the ground = €
SOH: sin € = opposite/hypotenuse
No the ladder won't be safe!!!
Now let's make it safe:
The ladder's length (w) is constant, so stays 12
So now let's ask in an inequality what height will be safe (75° or less)
what does that mean?? well as long as you put the ladder against the wall so that the height from ground to top of the ladder is < 11.6 ft!!
Hope that helps! :-D
