Answer:
The explicit formula is 15 + (n-1) -4
Step-by-step explanation:
The formula for an explicit formula is an = First number of the sequence (15) + (n-1)(times the amount of integers separating two different sequential numbers) which is -4.
For instance, since 15 is the first number, it will be a1 or 15. Next will be + (n-1) which is the same for every explicit sequence and the multiplier will be the difference between each number, which is -4 in the recursive sequence. As a result, the answer is 15 + (n-1) -4.
No. If no right angle exists, then it's not a rectangle.
Y = 1/3x + 2
Y = Mx + b
b would equal a positive 2 since the graph starts two units of the x-axis.
Then use the rise over run method for the rest. This means you up up 1 unit and three units to the left or 1/3.
Answer: It equals the same because you can't factor variables that are different.
Answer:
A = a + b / 2 x h
Step-by-step explanation:
Area is equal to side one plus side two divided by two then you multiply by the height of the trapezoid. Hope this helps!
