Answer:
Q(t) = 14.8(1.392)t
Explanation:
Let us consider a decay model defined as Q=abt, where t is the time, b is the rate, a is a constant and Q is the quantity at time t
Now, at t=0 quantity = 14.8
Substituting t=0 in our model,
14.8=a
Now, at t=1, quantity = 20.61
Substituting t=1 in our model,
20.61 = 14.8b1,So,
b= 1.392
At t=2,
Q = 14.8(1.392)2 = 28.66 which satisfies our table,
at t=3,
Q = 14.8(1.392)3 = 39.92 which again satisfies the table value
Answer:
$279.25
Step-by-step explanation:
Multiply 6.50x43
![w = 279.50 + (0.5 \times 6.50) \times (43 - 40)](https://tex.z-dn.net/?f=w%20%3D%20279.50%20%2B%20%280.5%20%5Ctimes%206.50%29%20%5Ctimes%20%2843%20-%2040%29)
Multiply 0.5x6.50
![w = 279.50 + 3.250 \times (43 - 40)](https://tex.z-dn.net/?f=w%20%3D%20279.50%20%2B%203.250%20%5Ctimes%20%2843%20-%2040%29)
Add 43-40
![w = 279.50 + 3.250 \times 3](https://tex.z-dn.net/?f=w%20%3D%20279.50%20%2B%203.250%20%5Ctimes%203)
Multiply 3.250x3
![w = 279.50+ 9.750](https://tex.z-dn.net/?f=w%20%3D%20279.50%2B%209.750)
Solution
Answer:
6 pieces
Step-by-step explanation:
4/4 - 1/4 = 3/4
(3/4) / (1/8) = (3/4) * (8/1) = 24/4 = 6
