Answer:
200
Step-by-step explanation:
C = 0.007x² − 2.8x + 100
There are two ways we can find the minimum. The first is by noticing that this is an upwards parabola, so the minimum is at the vertex. For y = ax² + bx + c, the vertex is at x = -b/(2a).
x = -(-2.8) / (2 × 0.007)
x = 200
Alternatively, we can minimize C using calculus. Take the derivative with respect to x and set to 0:
dC/dt = 0.014x − 2.8
0 = 0.014x − 2.8
x = 200
Put one dot on (0,-2) , (4,0), (-4,-4) connect the dots that is your graph line.
Slope is 1/2 and you is -4

Answer:
Figure d)
Monopars are figures that have just one set of parallel lines.
Step-by-step explanation:
It looks like all the figures in group 1 have one set of parallel lines. In group 2, they either have 0 or 2. In group 3, only d has just one set of parallel lines.
So monopars are figures that have just one set of parallel lines.
