The graph below represents the solution set of which inequality?

option: B () is correct.

Step-by-step explanation:

We are given the solution set as seen from the graph as:

(-4,2)

1)

On solving the first inequality we have:

On using the method of splitting the middle term we have:

⇒  

⇒

And we know that the product of two quantities are negative if either one of them is negative so we have two cases:

case 1:

and

i.e. x>-2 and x<4

so we have the region as:

(-2,4)

Case 2:

and

i.e. x<-2 and x>4

Hence, we did not get a common region.

Hence from both the cases we did not get the required region.

Hence, option 1 is incorrect.

2)

We are given the second inequality as:

On using the method of splitting the middle term we have:

⇒

⇒

And we know that the product of two quantities are negative if either one of them is negative so we have two cases:

case 1:

and

i.e. x>2 and x<-4

Hence, we do not get a common region.

Case 2:

and

i.e. x<2 and x>-4

Hence the common region is (-4,2) which is same as the given option.

Hence, option B is correct.

3)

On using the method of splitting the middle term we have:

⇒

⇒

And we know that the product of two quantities are positive if either both of them are negative or both of them are positive so we have two cases:

Case 1:

and

i.e. x>-2 and x>4

Hence, the common region is (4,∞)

Case 2:

and

i.e. x<-2 and x<4

Hence, the common region is: (-∞,-2)

Hence, from both the cases we did not get the desired answer.

Hence, option C is incorrect.

4)

On using the method of splitting the middle term we have:

⇒

⇒

And we know that the product of two quantities are positive if either both of them are negative or both of them are positive so we have two cases:

Case 1:

and

i.e. x<2 and x<-4

Hence, the common region is: (-∞,-4)

Case 2:

and

i.e. x>2 and x>-4.

Hence, the common region is: (2,∞)

Hence from both the case we do not have the desired region.

Hence, option D is incorrect.

a. 32 degrees

step-by-step explanation:

here we have to use the rule.

m∠e = 1/2 (major arc - minor arc)

m∠e = 1/2 (212 - 148)

m∠e = 1/2 (64)

m∠e = 32 degrees

answer: a. 32 degrees
