Answer:
a)148.47
b)148.34
Step-by-step explanation:
Let π(x) be the prime-counting function that gives the number of primes less than or equal to x, for any real number x. For example, π(7) = 4 because there are four prime numbers (2, 3, 5, 7) less than or equal to 7.
We can see that π(7)=π(10) because there are four prime numbers (2,3,5,7) less than or equal to 10.
A good aproximation for π(x) is x / log x, where log x is the natural logarithm of x.
a)The number of primes between 1 and 1030.
1030/log(1030)=148.47
b) The number of primes between 1 and 1029.
1029/log(1029)=148.34
Extra: π(1029)=π(1030) because 1030 is not a prime.
Answer:
The correct option is C
Step-by-step explanation:
(x^3 +12x^2 +38x +26) / (x+4)
Use the coefficients of dividend.
And the divisor is -4:
Bring down 1 and multiply it by -4 and add to 12
12-4 = 8
Now multiply 8 by -4 = -32
48-32 = 6
Now multiply 6 by -4 = -24
26-24= R2
1 12 38 26
-4 -32 -24
_______________
1 8 6 R2
Thus the correct option is C ....
