Someone tell me if these sequences are arithmetic, geometric, or neither

1 answer:

5 0

1. A constant number isn't being added so it's not arithmetic. To get from 2 to 7, you'd be multiplying by 7/2 or 3.5. To get from 7 to 27, you'd be multiplying by 27/7 or 3.85. This means that there isn't a constant rate so it's not geometric either. This one is neither.

2. 16 divided by 4 is 4, 4 divided by 4 is 4, 1 divided by 4 is 1/4, so this one is geometric with a constant of 4.

3. To get from 71 to 62, subtract 9. To get from 62 to 53, subtract 9. This means that it's arithmetic with a constant of 9.

Answer:

364.8 ft^2.

Step-by-step explanation:

I assume you want the area of the figure.

Total area = area of the top triangle + area of the trapezium

= 1/2 * base * height + 1/2 * height * ( sum of the parallel sides)

= 1/2 * 18 * 6 + (14/2)( 18 + 26.4)

= 54 + 310.8

= 364.8 ft^2.

I serve a volleyball at a 730 angle with the horizontal, and an initial speed of 5.6 feet per second. What is the component form

noname [10]

You would split out the velocity into x and y components.
X component: 5.6cos(73)= 1.637i
Y component: 5.6sin(73)= 5.355j

Therefore velocity in its component form is 1.637i + 5.355j ft/s
