Answer:
an = 40 -7(n -1)
Step-by-step explanation:
The given sequence has terms with a common difference, so it is an arithmetic sequence. The formula for the general term of an arithmetic sequence applies:
an = a1 +d(n -1)
__
The first term of the given sequence is ...
a1 = 40
The common difference for this sequence is ...
d = 33 -40 = -7
Using these values in the equation for the n-th term, we have ...
an = 40 -7(n -1) . . . . . explicit formula for the n-th term
Answer:
16
Step-by-step explanation:
45 +25+25+10+10+19=134 so 150-135=16
The answer to the expansion of the expression, 3+5^2 is 28
<h3>How to expand an expansion</h3>
An expansion of an expression is the evaluation of the expression to its simplest form
Given:
3+5^2
= 3 + 5²
= 3 + (5 × 5)
= 3 + 25
= 28
Therefore, answer to the expansion of the expression, 3+5^2 is 28

First you must find the tenths place
7 .8 3 9
O T H Th
So, the 8 is in the tenths place. Now look at the number to it's right, 3.
Since 3 is less than 5, you just turn everything behind the 8, including the 3, into a zero, giving you 7.800 or 7.8
Answer:
x = 5, -1
Step-by-step explanation:
0 = 3x^2 - 12x - 15 or
3x^2 - 12x - 15 = 0
By solving for x, use the Quadratic Formula.
… x = 5 and/or -1
