Answer:
<em>The common ratio of the geometric sequence is -4</em>
Step-by-step explanation:
<u>Geometric Sequence</u>
A geometric sequence is defined as a series of numbers that follow a fixed pattern: Each term equals the previous term times a fixed number called the common ratio. The recursive formula is:

Where r is the common ratio.
We are given three terms of a geometric sequence:
18,-72,288,...
To find the common ratio, just divide each term by the previous term:

Make sure it's a fixed number and test with the third term:

Since both numbers coincide, the common ratio of the geometric sequence is -4
1 yard= 6 foot
1160 yards= 3480 foot
3480/60=58
It will take 58 minutes to travel 1160 yards
Answer:
the height of the building is 86.6m
Step-by-step explanation:
In the right triangle, the height which we are looking for is the opposite side, since it is opposite to the angle 60°
Now we need to find the height of the building
tanθ = Opposite side/Adjacent side
tan 60° = Opp side/Adj side
1.7321 = Opp side/50
1.7321 x 50 = Opp side
Opp side = 50 x 1.7321
Opp side = 86.6 m
Therefore, the height of the building is 86.6m.
Math wasn't discovered, it was invented. Math has been around since the beginning of time lol.
