<span>We have to find the product : ( 9 t - 4 ) ( - 9 t - 4 ) = - ( 9 t - 4 ) ( 9 t + 4 ) After that we can use the difference of squares. The formula is: ( a + b ) ( a - b ) = a^2 - b^2. In this case: - ( 9 t - 4 ) ( 9 t + 4 ) = - ( 81 t^2 - 16 ) = - 81 t^2 + 16 . Answer: B ) - 81 t^2 + 16.</span>
The first term of an arithmetic sequence is 1.2 with a common difference of 8.
<h3>What is a sequence?</h3>
It is defined as the systematic way of representing the data that follows a certain rule of arithmetic.
We have:
Tenth term of an arithmetic sequence = 73.2 or
a+(10-1)d = 73.2 ....(1)
Second term of an arithmetic sequence = 9.2 or
a+(2-1)d = 9.2 .....(2)
Where a is the first term and d is a common difference.
Solving equations (1) and (2)
From the equation (2) put the value of d in the equation (1), we get:
a+9(9.2-a) = 73.2
a+82.8 - 9a = 73.2
-8a = -9.6
a = 1.2
Thus, the first term of an arithmetic sequence is 1.2 with a common difference 8.
