Answer:
π radians
Step-by-step explanation:
The arc cos(- 1) in degrees is 180° and 180° = π radians
You have to find a common denominator for both fractions. I chose the denominator to be 10, so the 1/2 will become 5/10, and 1/5 will become 2/10.
Subtract 5/10 from 2/10. You will get -3/10.
Answer: -3/10
You can check your answer by solving 1/2-3/10=1/5 to see if it is true. (It is:)
Answer:
38
Step-by-step explanation:
Answer:
Step-by-step explanation:
Given:
From the graph shown,
The broken line means that the inequality sign will be either < or >.
The shaded region is to the left of the broken line. This means that 
.
Now, in order to find equation of line, we need slope and y-intercept.
From the graph, the y intercept is at 
. So, y intercept is 1.
Also, if we consider two points 
on the line, then slope is given as:
Therefore, the equation of the line is given as:
But as the shaded region is to the left of the line,
∴ 
is the correct answer.
The intersection of the parabola with the x-axis is the solution of this equation. Accordingly, if the parabola does not intersect with the x-axis, there will be no solutions
