(a) False. The number 7 is NOT an element of set B as 7 is not in the set B (2, 3, 4 and 0 are though)
(b) False. 3 is a member of set A. It is the third element listed in the set. So saying "3 is not a member of set A" is a false claim
(c) True. The value 0 is found in set B. It is the last element listed.
Final Answer: Choice C)
Answer:
Third answer
Step-by-step explanation:
1 x 7 = 7
36 x 7 = 252
Answer:
15.5
Step-by-step explanation:
So the formula here is the square of the tangent length is equal to the product of the exterior part of the secant line and total length of the secant.
So that means we have x^2=10(14+10).
After simplifying the right hand side we have the equation is x^2=10(24) or x^2=240.
To get rid of the square on the x, we square root both sides.
x=sqrt(240)
x=15.49193338
To the nearest tenths, the answer is x=15.5
So 15.5 inches is the length of x.
2) 9=-7m+1-6
9=-7m-5
9+5=-7m
14=-7m
m=14/-7=-2
5) -36=6(2-8n)
-36/6=2-8n
-6=2-8n
-6-2=-8n
-8=-8n
n=1
All we have to do is subtract -2 - 4 and we get -6, and multiply -6 * 8 to get our answer.
Answer: -48.
