\huge\text{Hey there!}


\mathsf{z^2 \times (x - y)}

\mathsf{= 5^2 \times (9 - 3)}

\mathsf{= 5 \times 5 \times (9 - 3)}

\mathsf{= \bold{25}\times(9 - 3)}

\mathsf{= 25\times \bf 6}

\mathsf{= \bf 150}


\huge\text{Therefore, your answer should be: }

\huge\boxed{\frak{150}}\huge\checkmark

What is the major difference between Fourier Transform and Z-Transform??.
never [62]
<span>The Z transform is related to Laplace transform and is applied to analyze digital circuits. The Fourier transform, on the other hand, is a type z-transform, i.e z-transform which is used in spectrum analysis and calculation of the energy density of the signal. The difference lies on the field of application.</span>

Find the area of the following shape. You must show all work to receive credit A (-4, 0), B(0, 4), C(2, 2), D(1,0)
natulia [17]

9514 1404 393

Answer:

  13 square units

Step-by-step explanation:

See the attached figure.

The horizontal dashed line divides the figure into two pieces:

  • a triangle 4 wide and 2 high
  • a trapezoid 2 high with bases 5 and 4

The appropriate area formulas can be used to find the areas of these. The figure's area will be their sum.

  A = (1/2)bh = (1/2)(4)(2) = 4 . . . . square units

  A = (1/2)(b1 +b2)h = (1/2)(5 +4)(2) = 9 . . . . square units

The area of the shape is ...

  (4 +9) square units = 13 square units

Combine like terms 4a2-3b2+ 4b + 10a2
jolli1 [7]

Answer:

14a² - 3b² + 4b

Step-by-step explanation:

Like terms are the terms that have similar stuff on it, like same variables, no variables, and stuff like that.

4a2-3b2+ 4b + 10a2

4a² and 10a² is similar. 4a² + 10a² = 14a²

Now, the equation is 14a² - 3b² + 4b. There is no more like terms left, so that is the answer.

Hope this helps!!
