Answer:
The coefficient of the fifth term is 126.
Step-by-step explanation:
The question implies that after the expansion of , 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,
= + + + + + + + + +
So, from this expansion, the fifth term is . 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
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.
Answer:
Step-by-step explanation:
we are given
sequence is geometric
so, we can use nth term formula
we have
we have to find a9
so, we can plug n=9
we get
