Answer:

The second and third one.

Step-by-step explanation:

If you use a calculator and do 3 x 3 x 3 x 3 x 3 it equals 243. If you do 3 x 3 x 3 x 3 it equals 81 and then you do 81 x 3 it equals 243.  

I hope this helps.

. Suppose that the signal x(t) = 2e −t/3 + e −t + 3e −t/2 is measured in the presence of noise distributed uniformly in the inte
galben [10]

Step-by-step explanation:

An exponentially decaying signal is of the form x(t) = Ce^(-αt) in terms of an initial value C and a decay rate α > 0. The signal equals a fraction 1/e of its initial value after the characteristic time scale t = 1/α.

Given

x(t) = 2e^(-t/3) + e^(-t) + 3e^(-t/2)

The decay rates are: 1/3, 1, and 1/2.

The slowest decay rate α is the minimum of {1/3, 1, 1/2} = 1/3.

The corresponding time scale

is only 2/3 times larger than the next faster decay rate 1/2, so the decay rates are NOT well separated. The slowest component is larger than 0.5 as long as t < (ln3)/0.5 ≈ 2.2.

The other two components add

up to more than the value of the slowest component. We conclude that the component with slowest decay rate dominates measurements on any interval even in the presence of noise.

How many solutions are there to the equation below?<br> 8x + 47 = 8(x + 5)
qaws [65]

Answer:

there are 0 solutions to the equation

Step-by-step explanation:

To know how many solutions are in the problem, we have to solve for x and see what result we have left. According to the result, we will know how many solutions there are

8x + 47 = 8(x + 5)

8x + 47 = 8*x + 8*5

8x + 47 = 8x + 40

8x - 8x = 40 - 47

0 = -7

As we can see we are left with an equality that is not fulfilled, this means that there is no solution to the problem, at least in the field of real numbers

sergey [27]

Answer:

fifth graders= 93 shirts

sixth graders= 156 shirts

teachers= 51 shirts

Step-by-step explanation:

31% of 300 is 93

52% of 300 is 156

156+93= 249

300-249= 51
