Answer: Option D: R = {3, 9, 12}
Step-by-step explanation:
The range of a function is the set of the possible outputs of a function:
if we have the function f(x) = y, the values of x are the domain, and the values of y are the range.
In the image, the set at the right is the output, so the set in the right is the range.
such that we have the pairs (-2,3) (2, 3) (3, 9) (4, 12)
So the range will be R = {3, 9, 12}
Answer:
A
Step-by-step explanation:
Distance covered by Amy in one hour = 1/3 x 15 miles = 5 miles
Distance covered by John in one hour = 1/5 x 30 miles = 6miles
As a result, John would jog 1 mile (6-5) farther than Amy, the answer is A

Step-by-step explanation:
Rectangular form:
z = -2.1213203-2.1213203i
Angle notation (phasor):
z = 3 ∠ -135°
Polar form:
z = 3 × (cos (-135°) + i sin (-135°))
Exponential form:
z = 3 × ei (-0.75) = 3 × ei (-3π/4)
Polar coordinates:
r = |z| = 3 ... magnitude (modulus, absolute value)
θ = arg z = -2.3561945 rad = -135° = -0.75π = -3π/4 rad ... angle (argument or phase)
Cartesian coordinates:
Cartesian form of imaginary number: z = -2.1213203-2.1213203i
Real part: x = Re z = -2.121
Imaginary part: y = Im z = -2.12132034
