Answer:
Step-by-step explanation:
Let the consecutive even numbers be 2n , (2n + 2) , (2n +4), (2n + 6)
2n + 2n+2 + 2n+4 + 2n+6 = 180
Add like terms
<u>2n + 2n + 2n + 2n</u> + <u>2 + 4 + 6</u> = 180
8n + 12 = 180
Subtract 12 from both sides
8n + 12 - 12 = 180 - 12
8n = 168
Divide both sides by 8
8n/8 = 168/8
n = 21
2n = 2*21 = 42
2n + 2= 2*21 +2 = 42 +2 = 44
2n +4 = 2*21 + 4 = 42 + 4 = 46
2n +6 = 2*21 + 6 = 42 + 6 = 48
The 4 consecutive even integers: 42, 44 , 46 , 48
The vertex form of parabola is,
Where is vertex point.
In this case our parabola is given by,
Hence the vertex is at .
Hope this helps.
For this case we have the following polynomial:
To answer the question, what we must do is rewrite the polynomial in its standard form.
We have then that the polynomial will be given by:
Therefore, we have the ordered polynomial in descending form of exponents.
Therefore, the second term of the polynomial is:
Answer:
The second term of the polynomial is given by:
First in order to solve you need to get rid of the fraction. You can do so by multiplying to entire equation by the denominator like so...
5(5r - 1/5) = (4/5)5
25r - 1 = 4
Then to isolate the variable you need to add 1 to both sides.
25r = 5
Then you divide.
r = 5/25
Simplify.
r = 1/5
I hope this helps love! :)
