Answer:

8/9

Step-by-step explanation:

Lets say

X=0.8888888...

Then,

10X=8.8888888...

So,

10X-X=8.8888888..−0.88888888...=8

9X=8

X=8/9

y = 6tan(\frac{x}{2}) - 3

Let y = 0, since the x-intercept occurs at y = 0.
3 = 6tan(\frac{x}{2})
tan(\frac{x}{2}) = \frac{1}{2}
\frac{x}{2} = tan^{-1}(\frac{1}{2})
x = 2tan^{-1}(\frac{1}{2})

x = 0.927295218...

\text{General form: } x = 0.9273 + n\pi

We know this because the tangential graph is period every pi radians. The sinusoidal and co-sinusoidal graph are periodic every 2pi radians.

In the late 18th century, a decimal clock was proposed, in which there were 100 'minutes' in one 'hour' and 10 'hours' in one da
Marrrta [24]

Answer:

2:50

Step-by-step explanation:

On an ordinary clock, there are 24 hours.

1)  6/24 = 0.25   (The percentage in which the day has passed)

2) 10 (total hours in a day in the decimal clock) * x 0.25 = 2.50

3) 2.5 Hours. On a typical clock, that would read 2:30, however, because the decimal clock proposes that there are 100 minutes in one hour, it will be 2:50, Therefore, the clock will display 2:50

f(x) = 2x + 7

f(-3) is x = -3

<u>Step 2: Evaluate</u>

  1. Substitute:                   f(-3) = 2(-3) + 7
  2. Multiply:                       f(-3) = -6 + 7
  3. Add:                             f(-3) = 1
