Mathematics
1 answer:
matrenka [14]4 years ago
7 0

Answer:

Step-by-step explanation:

a(n) = n² - 3n - a(n-1) and a(1) = 4

We have a(1) = 4 and want a(2) (for which n = 2).

a(2) = 2² - 3(2) - a(2-1)  →  a(2) = 4 - 6 - 4 = -6 = a(2)

a(3) = 3² - 3(3) - (-6) = 9 - 9 + 6 = 6 = a(3)

a(4) = 4² - 3(4) - 6 = 16 - 12 - 6 = -2 = a(4)

a(5) = 5² - 3(5) + 2 = 12 = a(5)

The maximum number of marks attainable at a mathematics competition is 60 suppose you obtained 40 marks your brother obtained 46
mixer [17]

Answer:

You = bronze

Your brother = silver

Your sister = gold

Step-by-step explanation:

Your marks: 40/60

Your brother's marks: 46/60

Your sister's marks: 49/60

You can simplify the fractions, but you don't have to:

40/60 = 2/3

46/60 = 23/30

49/60 = 49/60

Now, divide each of the numerators by the denominators (turn the fraction into a decimal).

2/3 = 0.6667

23/30 = 0.7666667

49/60 = 0.8166667

(Note that these are all approximations as the real answers go on forever)

Lastly, multiply them all by 100 to get the percent.

0.6667 x 100 = 66.67% - bronze

0.76667 x 100 = 76.667% - silver

0.816667 x 100 = 81.6667% - gold

WILL GIVE BRAINLY!!!!!!!!<br> Factor completely 2x2 + 2x − 12.
kipiarov [429]

Step-by-step explanation:

All of these terms have a common factor of 2, and when we take that out we get 2(x² + x - 6). To factor the polynomial in the parentheses, we have to find 2 numbers with a product of -6 and a sum of 1, and these are 3 and -2. Therefore, the final answer is 2(x + 3)(x - 2).

Hope this helps!
