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:
no jami can not mow 1 1/2 in 1 hour
Step-by-step explanation:
well 1/6 * 9 = 1.5
8 * 9 = 72
i would take her 1 hour and 12 minutes to mow
(4)^36
Multiply the exponent 6 by 6 to get the new exponent of 36
Solution: 5,400 feet^2
Step by step solution:
3/4=0.75
(80*0.75)(120*0.75)
(60)(90)
5400
5,400 feet^2
Hope that helps :)
Answer:
Step-by-step explanation:
vector u=<(11-(-7),(-5-2)>=<18,-7>
as direction is opposite to u
so vector v=-3(18,-7)=(-54,21)
