I'm guessing the equation is supposed to read
Move the constant term to the other side:
Take the inverse tangent of both sides:
(where n is an integer)
Since tan(π/3) = √3, we get
and solving for x gives
Answer:
t=0 or t=-1/2
Step-by-step explanation:
Solve for t over the real numbers:
t (2 t + 1) = 0
Split into two equations:
t = 0 or 2 t + 1 = 0
Subtract 1 from both sides:
t = 0 or 2 t = -1
Divide both sides by 2:
Answer: |
| t = 0 or t = -1/2
Answer:
The solution of the system of equations is the point
Step-by-step explanation:
we have
------> equation A
------> equation B
Using a graphing tool
we know that
The solution of the system of equations is the intersection point both graphs
The intersection point is
see the attached figure
therefore
The solution of the system of equations is the point
Answer:
The graph in the attached figure
Step-by-step explanation:
we have
Solve for z
Divide by 8 both sides
The solution for z is the interval ----> (-∞,2]
All real numbers less than or equal to 2
In a number line the solution is the shaded area at left of z=2 (closed circle)
using a graphing tool
see the attached figure
-16^-2
Since the exponent is negative, convert to fraction form
1/(-16^2)
Evaluate the exponent
1/256
Final answer: 1/256
