Given

See attachment for mapping diagrams

Required

Which represent function

For a mapping to be considered a function, each element of the input set must only point to 1 element of the output set.

Base on the above analysis, we have:

<u>Map A</u>

1 points to 6; 2 to 7; 3 to 8; and 4 to 9

<em>This is a function</em>

<u>Map B</u>

2 points to 0; 4 to 0; 6 to 0; and 8 to 0

<em>This is a function</em>

<u></u>

<u>Map C</u>

1 points to 8; 3 to 8; 5 to 9; and 7 to 9

<em>This is a function</em>

<u>Map D</u>

0 points to 2 and 5; 3 points 7 and 9

<em>This is not a function</em>

Cylinders are 3D figures, as they are solids with volume and take up space.

2D figures are flat figures that you can draw, like a square or circle.

1D figures are actually just a line, a segment, or a point, etc.

a circular racecar track has a radius ig 1.6 miles.about how many times must a car drive around the race track to drive 15 miles
madam [21]
He has to drive around the track about 1.5 times.

We first find the circumference:

C = 2πr = 2(3.14)(1.6) = 10.048

We now divide 15 by this:
15/10.048 ≈ 1.5
