f(x) = tan2(x) + (√3 - 1)[tan(x)] - √3 = 0
tan2(x) + √3[tan(x)] - tan(x) - √3 = 0
Factor into
[-1 + tan(x)]*[√3 + tan(x)] = 0
which means
[-1 + tan(x)] = 0 and/or [√3 + tan(x)] = 0
Then
tan(x) = 1
tan-1(1) = pi/4 radians
For the other equation
[√3 + tan(x)] = 0
tan(x) = -√3
tan-1(-√3) = -pi/3
so that
x = pi/4 or -pi/3 in the interval [0, 2pi]

20.4 is the answer because there is 12 cm so you would multiply 12 by 1.7.
Answer: -40 feet
Step-by-step explanation: the scuba diver starts at sea level (0) then swims down 30 feet (-30). after a couple minutes, goes down 10 feet more (-40) the scuba diver will now be -40 down from sea level. so it should be -40 because the scuba diver swam that much down.
lmk if this is incorrect, i'm not quit sure if it is or not. if i'm wrong, i'm so sorry!!

Answer:
Each question worth 5.
Step-by-step explanation:
Each question worth 5 Point because
5 x 20 = 100
Hence, 20 question each question worth 5 point.
If You get a 45% then you miss 11 question and only get 9 question correct..
9/20 x 100 = 45.
