3 0

1. Graph y = |x|. The graph looks like a "V" that opens upward, with vertex at (0,0).

2. Move the entire graph 1 unit to the left. The vertex will now be at (-1,0).

3. Darken (shade) the entire area ABOVE the graph.

Answer:

C. $72\pi$

Step-by-step explanation:

The radius of the circle is 24 units, then the area of the whole circle is

$\pi r^2=\pi \cdot 24^2=576\pi \ un^2.$

The shaded circle is limited by 45° angle, so its area is

$\dfrac{45}{360}=\dfrac{1}{8}$

of the area of the whole circle.

The area of the shaded circle is

$\dfrac{1}{8}\cdot 576\pi =72\pi \ un^2.$

Answer:

The choice D.

Step-by-step explanation:

$f(x) = {( \frac{1}{6} })^{x} \\ \\ f(3) = {( \frac{1}{6} })^{3} = \frac{ ({1})^{3} }{( {6})^{3} } = \frac{1}{216}$

Her exercise today, Amanda plans to both run and swim. Let

vlabodo [156]

R = laps she runs
s = laps she swims
each r (laps she runs) takes 5 min.
each s (laps she swims) takes 3 min.
She wants to run for 30 min.

So your inequality should = 30
