Answer:
YZ = 44
Step-by-step explanation:
Let the intersection of XW and YZ equal A. For this problem, we can use power of a point in the scenario where two secants intersect in the interior of a circle. We get the equation:
WA * AX = ZA * AY
We can substitute the values we are given to get:
(2x - 6)(21) = (x + 1)(30)
42x - 126 = 30x + 30
12x - 126 = 30
12x = 156
x = 13
Using segment addition postulate, we can say that:
YZ = YA + AZ
And we can plug in what we know from the diagram:
YZ = 30 + x + 1
We can also plug in the value of x, 13
YZ = 30 + 13 + 1 = 44
Answer:
c is actually correct lol
Step-by-step explanation:
g(x) = (x-4)(x+2)
set both (x-4) and (x+2) equal to zero
x-4=0
x=4
& bx+2=0
x=-2
c has 4 and -2 as x values
{ 9 } ∉ S. Answer C is not correct.
If subset A represent spinning a number less than 4, its sample space is
A ={ 1, 2 , 3 }. Therefore D is also false.
Answer:
True statements are;
A ) S = { 1, 2, 3, 4, 5, 6, 7, 8 }.
B ) If A is a subset if S, A could be { 1, 2, 3 }.
E ) If a subset A represents the complement of spinning an odd number, its sample space is A = { 2, 4, 6, 8 }.
