Answer:

the values of N for which there will be no spectral leakage are;

N = Integers multiple by 8

Step-by-step explanation:

Given that;

discrete-time sinusoidal segment x[n] = 6.2cos(0.75πn + 1)

Using DFT to compute the spectrum

The spectral leakage will not be present in the spectrum if the product f₀Td is an integer.

Here, f₀ is sinusoid's frequency and Td is the segment duration

Now we calculate the period of the signal

2π/ω = 2π/0.75π

ω =  2 / 0.75

( × 4 )

ω =  8 / 3

Here, the numerator value is the period of the signal

T₀ = 8

The spectral leakage will not be present in the spectrum if N is  the Integer multiple of period T₀.

Therefore, the values of N for which there will be no spectral leakage are;

N = Integers multiple by 8

6.14-(9+8)2

6.14-17(2)

6.14-34=

-27.86

Hope this helped!

The required simplified value of the 6.14-(9+8)2 is -27.86.

Given that,
An expression  is given, 6.14-(9+8)2
A simplified value is to be determined.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,

Here,
= 6.14-(9+8)2
Using the PEMDAS rule,
Using distributive property in order to solve the parenthesis first.
= 6.14 - 17 * 2
Following PEMDAS solve 17 * 2 first.
= 6.14 - 34
Now, subtraction
= -27.86

Thus, the required simplified value of the 6.14-(9+8)2 is -27.86.

Answer:

idek

Step-by-step explanation:

Answer:

one: 9

Two: D

Step-by-step explanation:

One

The symbol used is x≥8 so 8 is included in the function part. That would mean that F(x) = 9

Two

The value you need to use is -4x + 3. That's because -2≤x and the symbol ≤ makes - 2 inclusive.

-4(-2) + 3 = 8 + 3 = 11

3a

The function is decreasing over -4x + 3

It goes from 11 to -29 roughly. That means it's going from a positive to negative number. Definitely decreasing

3b

The function is a constant when x≥8. The value of the function is 9 no matter what x is.

3c

The function is increasing from - 2x to 8 which is going from -9 to 11

Answer:

65º

Step-by-step explanation:

(the sum of the angles of a triangle) 180- 65= 115

65= 30+ 35

180- 115=65

Answer:

I'm pretty sure the answer is 65

Step-by-step explanation:

30+35=65

180-65=115

So the 3rd angle in the triangle is 115°

Then you subtract 115 from 180 and get 65°

So S equals 65°

Step 1: Define

2/5(x - 2) = 4x

Step 2: Solve for x

Answer:

x = -2/9

Step-by-step explanation:

Multiply both sides by 5

2(x - 2) = 4x*5

2x - 4 = 20x            Subtract 2x from both sides

-4 = 18x                   Divide by 18

-4/18 = x

x = -2/9

Answer:

40

Step-by-step explanation:

16 is 40 percent that means that :

32 is 80 percent

8 is 20 percent.

32 + 8 is 40 ------  80 percent+ 20 percent =100 percent

40 is the number whose 40% is 16.

percentage, a relative value indicating hundredth parts of any quantity.

We need to find the number whose 40% is 16.

Let us consider the number be x.

Convert 40% to the decimal by dividing with 100

40/100=0.4

Now multiply zero point four with x which gives 16

0.4x=16

Divide both sides by 0.4

x=16/0.4

x=40

Hence, 40 is the number whose 40% is 16.

Answer:

  x = 6

Step-by-step explanation:

The angle bisector divides the triangle proportionally. Here, the top segment on each half is double the length of the bottom one, (8 = 2·4), so ...

  x = 2·3

  x = 6

_____

If you like, you can write that as a proportion:

  x/3 = 8/4

  x = 3(8/4) = 3·2 . . . . . multiply by 3 to get x by itself

  x = 6

Answer: x =2

Step-by-step explanation:

5x - 8 = 3x - 4

2x = 4

x = 2

checking the work:

5(2) - 8 = 3(2) - 4

10 - 8 = 6 - 4

2 = 2
