Answer:
π radians
Step-by-step explanation:
The arc cos(- 1) in degrees is 180° and 180° = π radians
Answer:
5
Step-by-step explanation:
First find the value of 1/10 of 500 :
⇒ 1/10 × 500
⇒ 500/10
⇒ <u>50</u>
Now divide 50 by 10 to get the missing value :
⇒ 50/10
⇒ 5
The solution for the inequality (x − 1)(x + 2) < 0 if x-1 < 0 and x+2 > 0 and x ∈ (-2, 1)
<h3>What is inequality?</h3>
It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.
We have:
(x -1)(x + 2) < 0
The product of (x-1) and (x+2) is less than zero it means:
x-1 < 0 and x+2 > 0 or
x-1 > 0 and x+2 < 0
Solve for first case:
x-1 < 0 and x+2 > 0
x < 1 and x > -2
x ∈ (-2, 1)
Solve for the second case:
x > 1 and x < -2
There will be no intersection region, so no solution in this case.
Thus, the solution for the inequality (x − 1)(x + 2) < 0 if x-1 < 0 and x+2 > 0 and x ∈ (-2, 1)
