Answer:
6 pencils
Step-by-step explanation:
divide $3.30 by $0.55 and you get 6.
F(x)=10-16/x
f'(x)=16/x^2
f'(c)=16/c^2
f(8)=10-16/8=10-2=8
f(2)=10-16/2=10-8=2
![f'(c)= \frac{f(b)-f(a)}{b-a} in (2,8), \frac{16}{c^2} = \frac{f(8)-f(2)}{8-2} , \frac{16}{c^2} = \frac{8-2}{8-2} ](https://tex.z-dn.net/?f=f%27%28c%29%3D%20%5Cfrac%7Bf%28b%29-f%28a%29%7D%7Bb-a%7D%20in%20%282%2C8%29%2C%0A%20%5Cfrac%7B16%7D%7Bc%5E2%7D%20%3D%20%5Cfrac%7Bf%288%29-f%282%29%7D%7B8-2%7D%20%2C%0A%20%5Cfrac%7B16%7D%7Bc%5E2%7D%20%3D%20%5Cfrac%7B8-2%7D%7B8-2%7D%0A)
4∈[2,8] is the required point.
Step-by-step explanation:
m<AEC= 180-152= 28°
m<CEB= 180-28=152°
m<FEC= 90+28=118°
Calculate the circumference of the full circle:
circumference = PI x diameter = 3.14 x 20 = 62.8 inches
the arc length is 160 degrees of the full circle
divide 160 by 360 (full circle) and multiply by the circumference:
160/360 x 62.8 = 27.9 inches
