Answer: A sum
Step-by-step explanation: The result of adding two or more numbers together is a sum.
{ 1,-3,9...}
an = a1 * r^(n-1)
a1 = first term = 1
r = common ratio = -3
so ur formula is : an = 1 * -3^(n-1)
Answer:
Please clarify the question so I can answer :)
Step-by-step explanation:
Make a drawing with a right triangle.
The opposite side, y, is the height of the dam less 1.65 m
The base or adjacent side is 90 m
The angle between the two sides is 90 m.
Then tan (26) = y / 90
y = 90 tan(26) = 90 (0.4877) = 43.90 m
The height of the dam is 43.90m + 1.65m = 45.55 m
Answer:
w < 7
Step-by-step explanation:
Since the inequality is an OPEN circle, that means the sign is < or >
Since the sign is going to the left that means it's < or ≤
The one that has both of these effects is <
Since the sign starts at 7, the inequality is w < 7
