Mixed numbers greater than 6 but less than 7 use an interval of 1/6 between each pair of numbers

GaryK [48]

Answer:

$[6\frac{1}{6},6\frac{1}{3},6\frac{1}{2},6\frac{2}{3},6\frac{5}{6}]$

Step-by-step explanation:

we have the compound inequality

$6 < x < 7$

where

x is a mixed number

The solution for the compound inequality are the numbers

$[6\frac{1}{6},6\frac{2}{6},6\frac{3}{6},6\frac{4}{6},6\frac{5}{6}]$

Simplify the numbers

$[6\frac{1}{6},6\frac{1}{3},6\frac{1}{2},6\frac{2}{3},6\frac{5}{6}]$

What is the equation of the graph

balandron [24]

Answer:

y=6^x-2

Step-by-step explanation:

Start with the parent function, a^x. The graph looks like it has been translated b units down, so our function is a^x+b. Now at x=0, y=-2. So b=-2. Next at x=1, y=3. 3=a^(1)-2, a=6. y=6^x-2 is the equation

Marco wrote the equation below.

Answer:

It is true, because the cosine function has a period of 2π

Step-by-step explanation:

Since, the period of the cos function is 360° ( or 2π radians ), it holds the property of:

$Cos(\theta)=Cos(2\pi +\theta)$

Taking $\theta$ as $-\frac{\pi}{2}$ , $(2\pi + \theta)$ is equal to $2\pi + (-\frac{\pi}{2})\\=2\pi - \frac{\pi}{2}\\=\frac{4\pi-\pi}{2}\\=\frac{3\pi}{2}$
