Answer:

Step-by-step explanation:

The speed of light in a vacuum is 186,282 miles per second (299,792 kilometres per second), and in theory nothing can travel faster than light. In miles per hour, light speed is, well, a lot: about 670,616,629 mph. If you could travel at the speed of light, you could go around the Earth 7.5 times in one second.

186 ,282 x 5  = 931 , 410  for 5 seconds

What is the average rate of change over the interval [0, 4]?
choli [55]

Answer:

\frac{3}{4}

Step-by-step explanation:

Given:

Interval, [0, 4]

Required:

Average range of change over [0, 4]

SOLUTION:

Find f(0) and f(4) from the graph:

f(0) = 0 (when x = 0, y = 0)

f(4) = 3 (when x = 4, y = 3)

Average rate of change = \frac{f(b) - f(a)}{b - a}

Where,

a = 0, f(a) = 0

b = 4, f(b) = 3

Plug in the values into the formula for average rate of change.

= \frac{3 - 0}{4 - 0}

= \frac{3}{4}

Average rate of change = \frac{3}{4}

A parabolic archway is 12 meters high at the vertex. at a height of 10 meters, the width of the archway is 8 meters. how wide is
Virty [35]
To solve this problem you must apply the proccedure shown below:

 1. You have that the <span>parabola is 12 meters high at the vertex and at a height of 10 meters, the width is 8 meter. 

 2. Therefore, you have:

 x^2=-4a(y^2-k)
 4</span>^2=-4a(10-12)
 16=-40a+48
 16=8a
 a=16/8
 a=2

 y=0
 x^2=-8(0-12)
 x^2=96
 x=√96
 x=9.79x2
 x=19.58

 3. Therefore, as you can see, the answer is: 19.58 meters.<span>

Which of the following points lies on the graph of the inverse of f(x) = 6^(x + 1)?
svetlana [45]
F ( x ) = 6^(x+1)
y = 6^(x+1)
x+1=log _{6}y \\ x = log _{6}y-1
The inverse is:
y = log _{6}x
And when you plug in the values: x = 1, y = - 1:
- 1 = log 1 - 1
- 1 = 0 - 1
 - 1 = - 1
so the answer is:
( 1, - 1 )
