Find the surface area of the composite solid.
Scilla [17]

Answer with Step-by-step explanation:

The given figure is a cuboid.

We know that surface area(S) of cuboid is given by:

S=2(lb+bh+hl)

Where l is the length, b is the breath and h is the height

Here, l=12 mm

         b=6 mm

and h=(7+2) mm=9 mm

Surface Area= 2(12×6+6×9+9×12)

                    =2(72+54+108)

                   = 2×234

                   = 468 mm²

Hence, Correct option is:

C. 468 mm squared

The distance, y, in centimeters, of an ant from a hole in the tree for a certain amount of time, x, in seconds, is shown in the
Alenkasestr [34]

Answer:

<h3>Part A</h3>

The graph is non-linear as it is not a continuous straight line (with only one slope).

<h3>Part B</h3>

<u>Increasing</u>:  the y-value increases as the x-value increases

<u>Constant</u>:  the y-value stays the same as the x-value changes

<u>Decreasing</u>:  the y-value decreases as the x-value increases

Therefore,

  • Increasing segment:  Between 0 and 2 seconds
  • Constant segment: Between 2 and 3 seconds
  • Decreasing segment: Between 3 and 5 seconds

<h3>Part C</h3>

For the first 2 seconds, the ant moves 6 cm from a hole in the tree at a steady speed of 3 cm per second. For the next second, the ant is at rest then turns around. For the next 2 seconds, the ant moves 6 cm back to the hole at a steady speed of 3 cm per second.  The ant then stops.
