To find the area of the figure, we divide it into two rectangles as follows:

And we find the area of each rectangle, which is given by:

\begin{gathered} A=b\cdot h \\ \text{where b = base and h = height} \end{gathered}

Area rectangle 1:

A=3\cdot10=30m^2

Area rectangle 2:

A=4\cdot6=24m^2

Therefore, the shaded area of the diagram is:

A=30+24=54m^2

Answer: 54 m^2

What is a cubic polynomial function in standard form with zeros 1,1,and -3?
Mekhanik [1.2K]

Answer:

f(x) = x³ + x² - 5x + 3

Step-by-step explanation:

The cubic polynomial has zeros at 1, 1, - 3.

Therefore, x = 1, 1, - 3 are the roots of the polynomial and hence, (x - 1), (x - 1) and (x + 3) will be factors of the cubic polynomial.

Hence, we can write the polynomial as a function of x as

f(x) = (x - 1)(x - 1)(x + 3)

⇒ f(x) = (x² - 2x + 1)(x + 3)

⇒ f(x) = x³ - 2x² + 3x² + x - 6x + 3

⇒ f(x) = x³ + x² - 5x + 3

So, this is the cubic polynomial function in standard form. (Answer)

Help me please, I’m stuck!
Veseljchak [2.6K]

Answer:

  5.  (x, y) ⇒ (x +5, y +1)

  6.  (x, y) ⇒ (x +4, y -1)

Step-by-step explanation:

A translation rule will generally have the form ...

  (x, y) ⇒ (x +h, y +k)

where (h, k) is the horizontal and vertical distance to the right and up that the figure is being translated.d

5) The image is 5 units right and 1 unit up from the original, so in the above formula, (h, k) = (5, 1) and the translation rule is ...

  (x, y) ⇒ (x +5, y +1)

__

6) The image is 4 units right and 1 unit down from the original, so (h, k) = (4, -1) and the transformation rule is ...

  (x, y) ⇒ (x +4, y -1)
