Answer:
Option A) 15
Step-by-step explanation:
We are given the following in the question:
The above expression describes a continuous signal.
We have to find the numerical value at t = 0.
Putting t = 0, we get,
Thus, the value of the signal is 15 at t = 0.
Option A) 15
1. The information given in the problem is:
- <span>Each arrangement uses 1 vase and 11 orchids.
- </span><span>Each case cost Marco $4.00.
</span> - C: the <span>total cost of the arrangement.
- r: </span><span>the cost of 1 orchid.
2. Therefore, you must multiply the cost of 1 orchid by the 11 orchids that he uses in e</span><span>ach arrangement,</span><span> and then, you must add the cost of 1 vase, as below:
C=11r+4
3. Finally, you can conclude that the</span> correct answer is the last option:
D)C=11r+4
Each piece must be 1/12 of the whole. They must add up to 9/8 of a meter.
(9/8 m) * (1/12) = 9 / 96 m long. But this reduces.
3 / 32 m long is lowest form of the answer
Check
If you multiply 3/32 by 12, you should get back to 9/8
3/32 * 12 = 36/32 = 9/8 which is what we tried to do.
