<h3>Answer:  1/8</h3>

Explanation:

Pick any term and subtract off the previous term to get the common difference.

So,

13/40 - 1/5 = 13/40 - 8/40 = (13-8)/40 = 5/40 = 1/8

Or

9/20 - 13/40 = 18/40 - 13/40 = (18-13)/40 = 5/40 = 1/8

The positive common difference value indicates this arithmetic sequence is increasing.

You Create 15 Centerpieces In 5 Hours.How Long Will It Take To Make 42 Centerpieces
kogti [31]
If you are making 15 center pieces per hour, then you are making 3 per hour.
15/5 = 3
Then you divide how many centerpieces you are making by 3.

42/3 = 14

It will take you 14 hours to make 42.

Hope this helps!

A ball is launched into the air from a height of 12 feet at time t = 0. The function that models this situation is h(t) = -2t2 +
tresset_1 [31]

Answer:

(a) 24 ft

(b) 2.5 s

Step-by-step explanation:

At t=2

h=-2(2)^{2}+10(2)+12=12+20-8=24 ft

Therefore, height after 2 s=24 ft

(b)

As it hits the ground, t is maximum and at maximum t, we differentiate the function to have

h=-4t+10  and h=0 hence

4t=10 hence t=10/4=2.5 seconds
