What is the factor of the model car? Please help

The scale factor of the model car is = 0.04166.

Step-by-step explanation:

Step 1:

The real-life car is much larger than the model car. For every inch on the model car, it is 2 feet on the real-life car.

We must convert 2 feet into inches. 2 feet = 24 inches.

So 1 inch on the model car is equal to 24 inches on the real-life car.

Step 2:

To calculate the scale factor, we divide the measurement after scaling by the same measurement before scaling.

In this case, the model car is the measurement after scaling and the real-life car is the measurement before scaling

The scale factor

So the scale factor is = 0.04166.

3. parallelogram

step-by-step explanation:

we turn each of our sides into direction vectors

ab=b-a=(3 - 7, 1 - 0) = (-4, 1)

bc=c-b=(1,6)

cd=d-c=(4,-1)

da=a-d=(-1,-6)

we see how the opposite sides have negated direction vectors; this is characteristic of a parallelogram.   we have congruent sides ab=cd and bc=da with unequal lengths because 1^2+6^2 is different from (-4)^2+1^2.   so it's not a square or a rhombus.  

we check the dot product of direction vectors of adjacent sides.   we have

ab dot bc = -4(1) + 1(6) = 2

that's not zero so the sides are not perpendicular.   we've ruled out rectangle.

the direction vectors indicate two pairs of congruent parallel sides, so we choose parallelogram over trapezoid.
