Should be C. 1/19. because if there's 20 maebles in the bag and without replacing the marble then it actually would be 2/18

Consider the given function and the given interval. f\(x\) = 2 sin\(x\) - sin\(2 x\) text(, ) [0 text(, ) pi] (a) Find the avera

Finger [1]

a. The average value of $f$ on the given interval is

$\displaystyle f_{\rm ave}=\frac1{\pi-0}\int_0^\pi(2\sin x-\sin2x)\,\mathrm dx=\boxed{\frac4\pi}$

b. Solve for $c$ :

$\dfrac4\pi=2\sin c-\sin2c\implies\boxed{c\approx1.238\text{ or }c\approx2.808}$

Can someone please help me with this?

Answer:

e = 29.0 will be the answer.

Step-by-step explanation:

Use the sine rule in the given triangle,

$\frac{EF}{\text{sin}(\angle D)}=\frac{DE}{\text{sin}(\angle F)}=\frac{DF}{\text{sin}(\angle E)}$

$\frac{d}{\text{sin}(35)}=\frac{16}{\text{sin}(30)}=\frac{e}{\text{sin}(115)}$

$d=\frac{16\times \text{sin}(35)}{\text{sin}(30)}$

d = 18.35

$\frac{16}{\text{sin}(30)}=\frac{e}{\text{sin}(115)}$

$e=\frac{16\times \text{sin}(115)}{\text{sin}(30)}$

e = 29.002

e ≈ 29.0

Therefore, e = 29.0 will be the answer.
