Answer:
- T(n) = 3n² - 4
- -189 doesn't belong
Step-by-step explanation:
<u>Given sequence:</u>
<u>The first differences:</u>
<u>The second differences:</u>
<u>If the sequence is T(n) = an² + bn + c, we have:</u>
<u>Using the first and second differences work out the value of zero term:</u>
This gives us c = - 4
<u>Now we have:</u>
<u>The first term is T(1) = -1, substitute n = 1 and find the value of b:</u>
- 3(1²) + b*1 - 4 = - 1
- 3 + b - 4 = - 1
- b = 0
<u>The nth term is:</u>
<u>Now lets find if -189 belongs to this sequence:</u>
- - 189 = 3n² - 4
- 3n² = - 185
The left side is positive and the right side is negative so the answer is also negative
Answer:
60:100
Step-by-step explanation:
100/10 = 10
6 x 10 = 60
therefore, the equivalent ratio would be 60:100
Answer:
$3, $11
Step-by-step explanation:
The profit function P(x) will be zero when either of its factors is zero. The left factor (x-3) is zero when x=3. The right factor (x-11) is zero when x=11.
Prices of $3 or $11 will result in $0 annual profit.
_____
<em>Additional comment</em>
A price halfway between these values, at (3+11)/2 = 7, will produce maximum profit, $32 million.
Hello,
Here is your answer:
The proper answer to the question is option A "3".

Answer:
The answer is C which is 15
Step-by-step explanation:
M decreased by 12 is equal to negative 6
That means:
12 - M = -3
or, 12 - (-3) = M
or, M = 12 + 3
. °. M = 15 <em><u>Ans</u></em>
