Answer:
x = 2 - sqrt(19/6)
x = 2 + sqrt(19/6)
Step-by-step explanation:
The answer is C, because there are three triangles, so you multiple 3 time the area which is 8*(4+x)
Let us consider the triangles WKQ and MQK
WQ=KM (given) side
WK=MQ(given) side
KQ=KQ (common) side
so we have SSS congruency (option A)
The answer would be D. Survey a random sample of persons within each geographical region of the city.
This is because the other 3 answers are biased samples of data, which could sway the data collected and/or the decision that is made upon it.
Hope this helps! :)
Answer:
<u>-53</u>, f(n) = -6(n-1) + 13
Step-by-step explanation:
given the equation to this linear/arithmetic sequence for the nth term: f(n) = -6(n-1) + 13
f(12) = -6(12-1) + 13
f(12) = -6(11) + 13
f(12) = -66 + 13
f(12) = -53
*substitute and simplify*
______________
f(n) = f(1) + d(n-1)
given f(1) = 13, f(2) = 7, and f(3) = 1
7-13 = 1-7 = <u>-6</u> = d
= f(1) + d(n-1)
f(1) = <u>13</u> so
the equation must be f(n) = <u>13</u> <u>-</u><u> </u><u>6</u>(n-1) or -6(n-1) + 13
