Write first four terms of an AP when the first term is -2 and common difference is O.​
Nina [5.8K]
<h3>Answer:  -2, -2, -2, -2</h3>

Explanation:

If the common difference is 0, then we're adding 0 to each term to get the next term. However, adding 0 doesn't change the number. So that's why we have the same thing written four times.

As another example, let's say the common difference was 1 instead of 0. That would mean the first four terms are -2, -1, 0, 1 since we add 1 to each term to get the next one (eg: -2+1 = -1).

The restaurant in the Space Needle in Seattle rotates at the rate of one revolution per hour. (Round your answers to two decimal
Natalija [7]
A) 130 mins = 2 hours 10 mins or 2 and 1/6 hours... so 2 and 1/6 revolution. and 1 revolution is equal to 2*pi radians 
<span>ANSWER: 13/6 (2 and 1/6) * 2*pi = 13.6 radians </span>

<span>b) 8/13.6 = x/(13/6) so x = 0.2715 hours or 16 and 1/3 minutes </span>

<span>c) if the restaurant is 21 meters, the radius is 10.5 meters, and the circumference is 2*pi*r so circumference = 65.97 meters. </span>

<span>2 and 1/6 revolution is going around the circumference 2 and 1/6 times, so simply multiply 65.97 by 13/6 </span>

<span>ANSWER: about 143 meters</span>

Factor this expression completely and then place the factors in the proper location. Note: Place factors alphabetically!
Usimov [2.4K]

To solve this problem you must apply the proccedure shown below:

1. You have the following expression given in the problem above:

mn - 4m - 5n + 20

2. The first thing you must do to factor the expression is to group the terms, as following:

(mn-4m)+(-5n+20)

3. Now, choose the greatest common factor of each group:

m(n-4)-5(n-4)

4. Now, you need to factor the expression by factoring out the n-4

(m-5)(n-4)

The answer is: (m-5)(n-4)
