Answer:

Arc length of circle with circumference 18 and an arc with a 120° central angle is:

6

Step-by-step explanation:

The arc length of a circle is given by:

Here, circumference=18

i.e. 2πr=18

and

Arc length=

Hence, Arc length of circle with circumference 18 and an arc with a 120° central angle is:6

Hope that was helpful.Thank you!

Determine if the series is convergent or divergent 20-15+10-5....
Kazeer [188]

Answer:

Option b is correct.

The series 20-15+10-5....is Divergent

Step-by-step explanation:

Alternating series Test:

\sum_{n=1}^{\infty} (-1)^{n-1} (b_n) =b_1-b_2+b_3-........

b_n>0 satisfies:

  • b_{n+1} \leq b_n   for all n
  • \lim_{n\rightarrow \infty} b_n = 0

Then the series converges,

otherwise diverges.

Given the series: 20-15+10-5....

This is a alternating series:

\sum_{n=1}^{\infty} (-1)^{n-1} (20-5(n-1))

b_n = (20-5(n-1))

b_{n+1} = (20-5(n+1-1)) = (20-5n)

using the alternating series test;

b_{n+1} \leq b_n  for all n

\lim_{n\rightarrow \infty} b_n = \lim_{n\rightarrow \infty} (20-5(n-1)) = -\infty

⇒ the series diverges.

therefore, the given series i,e 20-15+10-5.... is divergent.

loris [4]

Answer:

8

Step-by-step explanation:

If you go along the x-axis to 9 and go up till it  meets the blue line and go left you will reach the integer 8 so f(9)=8

Greetings. As a beginner, I'm struggling a bit to learn calculus. May I know what is the derivative of x to the power 4 step by
elena-14-01-66 [18.8K]

If you're just starting calculus, perhaps you're asking about using the definition of the derivative to differentiate x^4.

We have

\dfrac{d}{dx} x^4 = \displaystyle \lim_{h\to0} \frac{(x+h)^4 - x^4}h

Expand the numerator using the binomial theorem, then simplify and compute the limit.

\dfrac{d}{dx} x^4 = \displaystyle \lim_{h\to0} \frac{(x^4+4hx^3 + 6h^2x^2 + 4h^3x + h^4) - x^4}h \\\\ ~~~~~~~~ = \lim_{h\to0} \frac{4hx^3 + 6h^2x^2 + 4h^3x + h^4}h \\\\ ~~~~~~~~ = \lim_{h\to0} (4x^3 + 6hx^2 + 4h^2x + h^3) = \boxed{4x^3}

In general, the derivative of a power function f(x) = x^n is \frac{df}{dx} = nx^{n-1}. (This is the aptly-named "power rule" for differentiation.)
