Answer:

x = -4

Step-by-step explanation:

3x+4= -8 (subtract 4 from both sides)

3x = -8 - 4 ( evaluate right hand side)

3x = -12 (divide both sides by 3)

x = -12 / 3 = -4

It's easy to show that $7\tan(4x)$ is strictly increasing on $x\in\left[0,\frac\pi8\right]$ . This means

$M = \max \left\{7\tan(4x) \mid \dfrac\pi{16} \le x \le \dfrac\pi{12}\right\} = 7\tan(4x) \bigg|_{x=\pi/12} = 7\sqrt3$

and

$m = \min \left\{7\tan(4x) \mid \dfrac\pi{16} \le x \le \dfrac\pi{12}\right\} = 7\tan(4x) \bigg|_{x=\pi/16} = 7$

Then the integral is bounded by

$\displaystyle 7\left(\frac\pi{12} - \frac\pi{16}\right) \le \int_{\pi/16}^{\pi/12} 7\tan(4x) \, dx \le 7\sqrt3 \left(\frac\pi{12} - \frac\pi{16}\right)$

$\implies \displaystyle \boxed{\frac{7\pi}{48}} \le \int_{\pi/16}^{\pi/12} 7\tan(4x) \, dx \le \boxed{\frac{7\sqrt3\,\pi}{48}}$

A forest contains about 500 trees. You randomly pick 67 trees and find that 27 of them are oaks. What is the experimental probab

Ulleksa [173]

Answer: You have a 12.2 percent chance

Step by step

500 divided by 5 is 100

61 divided by 5 is 12.2

12.2/100

What you do to 500 is what you do to the 61

You have a 12.2 percent chance

Hope this helps
