Answer:
c=√a²+b²
Step-by-step explanation:
You can use this equation to solve it.
The answer is n^4. This is calculated by just subtracting the exponents. Hope this was what you were asking.
A function is a repesentashion of time. past or befor so fg means function grafgh is what your exsplaining as in repacentation of wrk)bg, is what happend befor like 1990 no one knows so I would say D
because 4_4 16 4;3 22 is the closest between function and befor g and after becuse 44_16 is 2004 and 20016 do you see know go hard rock star ;-)
Step-by-step explanation:
that is
sum(2^r) for r=1 to n, plus sum(1/2) for r=1 to n.
and that is
sum(2^r) + n/2 for r=1 to n.
2^r is a geometric sequence with 2 being the common ratio (every new term is created by multiplying the previous term by 2).
and since r is starting at 1, the first term a1 = 2.
the formula for the sum of a finite geometric sequence is
Sn = a1×(1 - r^n) / (1 - r)
with r being the common ratio .
so, in our case
Sn = 2×(1 - 2^n) / (1 - 2)
Sn = (2 - 2^(n+1)) / -1 = 2^(n+1) - 2
and so, in total we get
2^(n+1) - 2 + n/2 = 2^(n+1) + (n - 4)/2
Answer:
<A = 30°
Step-by-step explanation:
5x - 18 = 3x + 42
2x = 60
60/2 = 30
<A = 30°
hope this helps :)
