Answer:

$344 {cm}^{2}$

Step-by-step explanation:

$area \: of \: the \: square \\ = 40cm \times 40cm \\ = 1600 {cm}^{3} \\$

$area \: of \: the \: circle \\ = \pi {r}^{2} \\ = 3.14 \times {(20)}^{2} \\ = 3.14 \times 400 \\ = 1256 {cm}^{2} \\$

$area \: of \: shaded \: region \\ = 1600 {cm}^{2} - 1256 {cm}^{2} \\ = 344 {cm}^{2} \\$

F(x) = x<br> Horizontal stretch by a factor of 2<br> Shift left 3 units<br> . Shift up 5 units

WARRIOR [948]

Answer:

f(x) = 0.5(x + 3)^2 + 5.

Step-by-step explanation:

The horizontal stretch is given by multiplying by 1/2 or 0.5:

f(x) = 0.5x^2

Now a shift of 3 to the left gives f(x) = 0.5(x + 3)^2.

5 units up gives 0.5(x + 3)^2 + 5.
