Answer:
The slope of the line is 3.
Step-by-step explanation:
Remember:
It rises to the right so the slope is negative
Slope = rise / run = 18 / -9 = -2
The y intercept is at y = -3 so using the form y = mx + b we get
y = -2x - 3 which is option B (answer)
Answer:
a) 14,1 cm
Step-by-step explanation:
If a circle passes through the vertices of a square then the diagonal of a square is a circle diameter.
We use Pytagoras Theorem to find out the length (L) of the diagonal given that:
L² = (20)² + (20)²
L² = 2* (20)²
L = √2 * 20
L = 1,4142* 20
L = 28,28 cm
L diagonal in the square is a diameter of the circle then radius of a circle is:
r = L/2 ⇒ r = 28,28 /2 ⇒ r = 14,14 cm
