Answer:
4.4
Step-by-step explanation:
x is hypotenuse of the right triangle.
One leg is 2.4 in.
Second leg = 7.4/2 = 3.7 in.
Using Pythagorean theorem
Hypotenuse²= (first leg)² + (second leg)²
x² = 2.4² + 3.7² = 19.45 in²
x=√19.45 ≈ 4.4 in

Answer:
There are a total of 2011 integer divisors.
Step-by-step explanation:
The only primes p such that 1/p has finite spaces after the coma are 2 and 5. If we divide a number with last digit odd we will obtain 1 extra digit after the decimal point and if we divide a number by 5 we will obtain 1 more digit if that number has a last digit in the decimal which is not a multiple of 5.
If we take powers of those primes we will obtian one more digit each time. In order to obtain more digits it is convinient to divide by a power of 2 instead of a power of 5, because the resulting number will be smaller.
If we want 2010 digits after the decimal point, we need to divide 1 by 2 a total of 2010 times, hence f(2010) = 2²⁰¹⁰, which has as positive integer divisors every power of 2 between 0 and 2010, hence there are a total of 2011 integer divisors of f(2010).
Answer:
The coefficient is 1
Step-by-step explanation:
There is an imaginary 1 in front of variables that becomes the coefficient if there isn't already a number there. If it was 5x squared, the coefficient would be 5.
