Answer:
Step-by-step explanation:
The axes x and y are calibrated in 0.25
If the circle is carefully considered, the radius r of the circle is:
r = -1.25 - (-2)
r = 0.75 units
The equation of a circle is given by:
The center of the circle (a, b) = (-2, -2)
Substituting (a, b) = (-2, -2) and r = 0.75 into the given equation:
You should divide when converting a larger unit to a smaller unit.
Answer:
y = 0.25
Step-by-step explanation:
Given y varies directly as x and inversely as the square of z then the equation relating them is
y = ← k is the constant of variation
To find k use the condition y = 48 when x = 100 and z = 5
k = = = 12
y = ← equation of variation
When x = 3 and z = 12, then
y = = 0.25
