Answer: 0

Step-by-step explanation: Natural numbers are the set of counting numbers that start at 0 an go on indefinitely.

Example ⇒ {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20...}

When we include 0 in the set of natural numbers, we get the new set of numbers which is called the set of whole numbers.

Example ⇒ {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20...}

All of the natural numbers are contained within the set of whole numbers.

Which variable is most important to the following problem? At 9:00 a.m., a wind speed of 20 miles per hour was recorded. After t

slavikrds [6]

Answer:

option-C

Step-by-step explanation:

We are given

At 9:00 a.m., a wind speed of 20 miles per hour was recorded

So, initial wind speed =20 miles per hour

Each measurement showed an increase in wind speed of 3 miles per hour

The strongest wind was recorded at 4:00 p.m

so,

top wind speed = initial wind speed + ( total number of hours between 9:00 am and 4:00 pm)*(change in wind speed)

top wind speed = 20 mph+(16-9)*3

$=20+7\times 3$

$=41$ miles per hour

Since, change in wind speed and initial wind speed are constant

but the number of hours it took for the wind speed to reach its minimum for the day can be changed

so, most important variables is

the number of hours it took for the wind speed to reach its minimum for the day can be changed

Geometry proofs<br> help me please :)

REY [17]

Answer:

2) Right angles always equal 90°

3) m∠F = 90° and m∠G = 90° which means they have the same angle measure.

4) Removing the m and replacing with the congruent symbol.

I'm not too sure how this goes but it should be something like that.

Help me plss, number 2.

Gnesinka [82]

Answer:

At (-2,0) gradient is -4 ; At (2,0) gradient is 4

Step-by-step explanation:

For this problem, we simply need to take the derivative of the function and evaluate when y = 0 (when crossing the x-axis).

y = x^2 - 4

y' = 2x

The function y = x^2 - 4 cross the x-axis when:

y = x^2 - 4

0 = x^2 - 4

4 = x^2

2 +/- = x

Hence, this curve crosses the x-axis twice, once at (-2,0) and again at (2,0).

The gradient at these points are as follows:

y' = 2(-2) = -4

y' = 2(2) = 4

Cheers.
