Answer:
A.) The sum of the product of the number of terms and the number of terms plus one.
Step-by-step explanation:
So, we have the sum of the first 22 positive even numbers:
S = 2 + 4+ 6 + ... + 44
We know the sum of such sequence is given by the (sum of the first number (2) and the last number (44)) multiplied by the number of terms (11).
S = (2 + 44) * 11 = 46 * 11 = 506
Answer A tells us it should be the sum of the number of terms (22) by the number of terms plus one (22 + 1 = 23).
S = 22 * 23 = 506
That's confirmed.
Answer B would give 22 * 21 = 462, so it's not right
Answer C would give 22 * 2 = 44, obviously not right
Answer D would give 22 * 22 = 484, close but not right.
Answer:
LMN has a larger area
Step-by-step explanation:
Given
RST
LMN
Required
Compare both areas
The area of triangle is:
For RST, we have:
Remove absolute signs
For LMN, we have:
Remove absolute signs
<em>By comparing both areas, we can conclude that LMN has a larger area</em>
Answer: I believe the 23rd, but if its in 10 years I must be wrong
I graphed the equation, but replaced t with x
Got it. Hope this will help.
