5. Suppose that we designed a new floating point unit that accelerates the floating point instructions by a factor of 5. We are

now looking for a benchmark to show off the new floating-point unit and we want the overall benchmark to show a speedup of 3. One benchmark we are considering runs for 100 seconds with the old floating-point hardware. How much of the execution time would floating-point instructions have to account for in this program in order to yield our desired speedup on this benchmark? [20%]

1. Why isn't solar energy usually the only power source for a region?
ale4655 [162]
1. Every region doesnt get the same amount of sunlight as the rest due to whether or location an example would be that a region with alot of rain could have clouds that wouldnt let the solar panels to absorb as much sunlight as a more dry and sunny place 
2 wind farms can be used to store energy for a power outage and a way to lower the cost of electricity to a farmer 
3 using hydro energy requires people to build a dam that pours the water over a mill that rotates and stores energy from it 
4 a type of waste created by nuclear power plants would be daily uses that have radiation such as plastic containers ,gloves , disposable overalls, boots or just plain radioactive waste.
5 would be the total mass of organisms in a given area or volume 
6 is a process to further limit carbon dioxide emissions from burning coal
7 is basically the means to tap into energy savings that over time become an asset 
8 turning down the water heater thermostat and turning off lights when not in use can save energy 
9 smart grids use timing grid to determine how long you use electricity for and for how much you used

Identify a logical operation (along
tankabanditka [31]

Answer: Provided in the explanation section

Explanation:

The Question says;

Identify a logical operation (along

with a corresponding mask) that, when

applied to an input string of 8 bits,

produces an output string of all 0s if and

only if the input string is 10000001.​

The Answer (Explanation):

XOR, exclusive OR only gives 1 when both the bits are different.

So, if we want to have all 0s, and the for input only 10000001, then we have only one operation which satisfies this condition - XOR 10000001. AND

with 00000000 would also give 0,

but it would give 0 with all the inputs, not just 10000001.

Cheers i hope this helped !!
