What is the coefficient of the fifth term in (a+b)^9

Answers

Answer:

The coefficient of the fifth term is 126.

Step-by-step explanation:

The question implies that after the expansion of (a+b)^(9), what would be the coefficient of the fifth term. This long expansion can be easily done by the application of the Pascal principle of expansion.

Thus,

(a+b)^(9) = a^(9) + 9a^(8)b + 36a^(7) b^(2) + 84a^(6)b^(3) + 126a^(5)b^(4) + 126a^(4) b^(5) + 84a^(3) b^(6) + 36a^(2) b^(7) + 9ab^(8) + b^(9)

So, from this expansion, the fifth term is 126a^(5)b^(4). And its coefficient is 126.

Answer:

If you expand this using pascals triangle you will see that the fifth term is 126a^5b^4

the coefficient is the number 126

a horse's heart beats 440 times in 10 minutes. A cow's heart bears 390 times in 6 minutes. which animal has a greater heart rate?

Answers

Answer:

The cow has a greater heart rate than the horse.

Step-by-step explanation:

The question demand we calculate the heart beat of each animal in relation to time . The number of heart beat per unit time can be computed as follows .

The horse heart rate is 440 heart beat in 10 minutes . The heart rate can be simplified as  

Rate = 440/10

Rate = 44 heart beat per minute

The cow heart rate can be simplified as

Rate = 390/6

Rate = 65 heart beat per minute

From the Heart rate calculated above the cow has a higher heart rate than the horse.

390 ÷ 6 = 65

440 ÷ 10 = 44

The cow has a greater heart rate.

When Derek planted a tree it was 36 inches tall. The tree grew 1 1/4 inches per year. The tree is now 44 3/4 inches tall. How many years ago did Derek plant the tree?

Answers

Original Height = 36 inches.

Change in height:

44(3)/(4) - 36 =  8(3)/(4)

Number of years : 

8(3)/(4) /  1(1)/(4)

=(35)/(4) /  (5)/(4)

=(35)/(4) *  (4)/(5)

=7

---------------------------------------------------------------
Answer; Derek has planted the tree for 7 years.

Given the geometric sequence where a1 = 3 and r = √2 find a9

Answers

Answer:

a_9=48

Step-by-step explanation:

we are given

sequence is geometric

so, we can use nth term formula

a_n=a_1(r)^(n-1)

we have

a_1=3

r=√(2)

we have to find a9

so, we can plug n=9

we get

a_9=3(√(2))^(9-1)

a_9=2^4\cdot \:3

a_9=48

Answer:

the answer to this geometric sequence is 48.

Braulio went I to the museum at 11:17 a.m. Then he had an appointment so he left the meuseum at 2:35. How long was he at the museum

Answers

Every hour is 60 minutes, there is 43 minutes before 12:00, and 155 minutes after 12:00
43 + 155 = 198
He was at the museum for 198 minutes, or 3 hour and 18 minutes.
well u subtract 11:17 to 2:35 which is 8 hours and 82 minutes but there is only 60 minutes in a hour so it is 9 hours 22 minutes
