Answer:
850 words can be typed in 17 minutes
Step-by-step explanation:
Divide 300 by 6 and multiply it by 17 and that is your answer, 850.
Answer:
x ∈ {2π/3, π, 4π/3} ≈ {2.09440, 3.14159, 4.18879}
Step-by-step explanation:
The equation can be put into standard form by adding 1:
2cos²(x) +3cos(x) +1 = 0
(2cos(x) +1)(cos(x) +1) = 0
Values of cos(x) that make this true* are ...
cos(x) = -1/2 . . . . . . . . . true for x=2π/3, x=4π/3
cos(x) = -1 . . . . . . . . . . . true for x=π
__
A graphing calculator can be helpful here, too.
_____
* from your knowledge of the short table of trig functions and their signs in different quadrants
(-1)+(-6)= -7
-7 + 6 = -1
therefore, the answer is 6.

it ia pretty simple my guy. All you neee to do is subsitute the numbers for the X on the left-side
Answer/step-by-step explanation:
The graph of f(x) above is said to be the quantity of liquid a cylinder holds when poured into it at a given time, x.
This means the quantity of the liquid poured in the cylinder is a function of time.
f(x) values (quantity of liquid) are plotted on the y-axis, while x values (time) are plotted on the x-axis.
f(3) is the value at the y-axis when x = 3. Thus, when x = 3, y = 6.
Therefore, the value of f(3) = 6
f(3) = 6, represents the quantity of liquid poured in the cylinder at 3 seconds.
