Answer:
I think -2,-2 is is the function strictly linear.
Answer:
180degreesStep-by-step explanation:
Given the complex value
z² = -81i
z = (-81i)^1/2
Get the argument of -81i
theta = arctan(y/x)
theta = arctan(-81/0)
theta = -90degrees
theta = -π/2
Since tan is negative in the secind quadrant
theta = π - π/2
theta = π/2
According to demoivres theorem
theta = 1/2 * π/2
theta = π
theta = 180degrees

Answer:
X - 2.
Step-by-step explanation:
x - 2
----------------------------
x2 – x + 1 ) x3 – 3x2 + 3x – 2
x3 - x2 + x
-------------------
-2x^2 + 2x - 2
-2x^2 + 2x - 2
---------------------

Answer:
70 gallons
Step-by-step explanation:
x gallon of 50%
x * 0.5 + 70 * 0.3 = (x + 70) * 0.4
0.5x + 21 = 0.4x + 28
0.1x = 7
x = 70
