The circumference of a circle is 2PiR.
Since we're just left with 8Pi, we can divide 8 by 2 to get the Radius.
Our radius is 4.
Your answer is B.)
Answer:
subtract 5
Step-by-step explanation:
283-5=278 278-5=273
f(x)=<span>3x. </span>Solution: If we take ln in both side of this equation and differentiate it, we get lnf(x)=ln3x. ∴ lnf(x<span>) = xln </span>3. ∴ d dx. (lnf(x<span>)) = d dx. (xln </span>3<span>).</span>
<span>The infinite series whose terms are the natural numbers 1 + 2 + 3 + 4 + â‹Ż is a divergent series. The nth partial sum of the series is the triangular number
{\displaystyle \sum _{k=1}^{n}k={\frac {n(n+1)}{2}},} \sum_{k=1}^n k = \frac{n(n+1)}{2},
which increases without bound as n goes to infinity. Because the sequence of partial sums fails to converge to a finite limit, the series does not have a sum.
Although the series seems at first sight not to have any meaningful value at all, it can be manipulated to yield a number of mathematically interesting</span>
Answer:
two real solution
Step-by-step explanation:
x^2 + 10x − 25 = 0
we can solve this by finding out the value of x
lets assume the equation is a\times x^{2}+b\times x+c=0
x=-b\pm \sqrt{(b^{2}-4ac)}\div 2a
x=-10\pm\sqrt{100+4*25}\div2
x=-5\pm5\sqrt2
then we get both real value of x
so two real solution
