Step-by-step explanation:

if you were to be solving for be you it will need to be an equation in order to be able to be solved but in this format it is nearly impossible to obtain an answer.

if you are trying to simplify it as far as possible, simply take out the highest number that goes into both numbers, seen as only the 6 has a variable. in this case the highest number would be 3, so your answer would be 3( -2b - 5 ). hope this was hat you were doing!

The 1992 world speed record for a bicycle (human-powered vehicle) was set by Chris Huber. His time through the measured 200 m st

Reil [10]

Answer:

a) 30.726m/s and b) 5.5549s

Step-by-step explanation:

a.) What was Chris Huber’s speed in meters per second(m/s)?

Given the distance and time, the formula to obtain the speed is

$v=\frac{d}{t}$ .

Applying this to our problem we have that

$v=\frac{200m}{6.509s}= 30.726m/s$ .

So, Chris Huber’s speed in meters per second(m/s) was 30.726m/s.

b) What was Whittingham’s time through the 200 m?

In a) we stated that $v=\frac{d}{t}$ . This formula implies that

$t=\frac{d}{v}$ .

First, observer that $19\frac{km}{h} =19,000\frac{m}{h}=\frac{19,000}{3,600}m/s= 5.2777m/s$ .

Then, Sam Whittingham speed was equal to Chris Huber’s speed plus 5.2777 m/s. So, $v=30.726\frac{m}{s} +5.2777\frac{m}{s}= 36.003 m/s.$

Then, applying 1) we have that

$t=\frac{200m}{36.003m/s}=5.5549s.$

So, Sam Whittingham’s time through the 200 m was 5.5549s.

Teh slope between two points is calculated by finding the change in y-values and dividing by the change in x-values. for example

Nimfa-mama [501]

Hi there!

The change of y-values is
- 15 - 22 = - 37
The change of x-values is
7 - - 8 = 7 + 8 = 15

Therefore, the slope of this line is
$\frac{ - 37}{15} = - 2 \frac{7}{15}$

It depends on what way the figure is translated, but it's possible it could be a dilations, reflection, rotation, etc.

Does Biased mean random or not random?

mote1985 [20]

Biased most likely means not random in this context. The actual definition is "unfairly prejudiced for or against someone or something"
