Hello the Answer:<span>x><span>15</span></span>
We can use the general term of the arithmetic series. Look:
Where:
: first term, 15.
: last term, 87.
n: number of terms (what we looking for);
r: reason, which is equal to the difference between two terms, that is, 3.
Let's go to the calculations.
There are 25 terms.
Answer:
The final price of share is $84
Step-by-step explanation:
Initial price of share = $ 80
The price of share is dropped by 15% on Tuesday
Drop in share = 15 % of 80 = 0.15×80 = $12
Price of share after 15% drop in price = $80 -$12 = $ 68
Price of share increased by $7 on Wednesday
Price of share on Wednesday = $68 +$7 =$ 75
on Thursday the price of share was increased by 12%
So the price of share on Thursday = price of share + 12 % of price of share
= $75 +12 % of $ 75
= $75 +0.12 ×$ 75
= $ 75 +$9 = $ 84
The final price of share is $84
Answer:
All systems have 2 real solutions.
Explanation: there are X and Y unknowns.
Answer:) Let p(x) = x51 + 51 . …(i)
When we divide p(x) by x+1, we get the remainder p(-1)
On putting x= -1 in Eq. (i), we get p(-1) = (-1)51 + 51
= -1 + 51 = 50
Hence, the remainder is 50.
