Answer:
The answer is 64.
Step-by-step explanation:
To find the volume of a prism, you multiply l x w x h (length x width x height). The length is 8, width is 4, height is 2. 8 x 4 = 32, 32 x 2 = 64.
hope this helped plz tell me if i was right!!!
40 because you would divide the miles by hours to find the rate of change.
120/3= 40
Answer: d. None of the above are correct.
Step-by-step explanation: Noise is a superfluous random alteration in an eletrical signal. There are different types of noises created by different devices and process. Thermal noise is one of them. It is unavoidable because is created by the agitation of the charge carriers, due to temperature, inside an eletrical conductor at equilibrium and is present in all eletrical circuits.
The formula to find the thermal noise power (N) is: N =
.T.B, where:
is Boltzmann constant (1.38.
J/K);
T is temperature in Kelvin;
B is the bandwith;
Calculating the thermal noise power:
N = 1.38.
·292·40
N = 16118.4.
dBm
The thermal noise power [N] = 16118.4.
dBm
Noise power density or simply Noise density (N₀) is the noise power per unit of bandwith and its SI is watts per hertz.
For thermal noise, N₀ = kT, where
<em>k </em>is the Boltzmann constant in J/K;
T is the receiver system noise temperature in K;
N₀ = 1.38.
. 292
N₀ = 402.96.
W/Hz
The thermal noise power density [N₀] = 402.96.
W/Hz
Convert all the improper fractions into mixed numbers, then simplify. Then, you do the operations.
I know for 2x you would go up 2 over 1 but I don’t know about -7?? Maybe down
