There are about 1.6 km in every mile. write an expression to represent the approximate number of kilometers in m miles. then use the expression to find the approximate number of kilometers in 5 miles

1.6M kilometers, 8 kilometers

Step-by-step explanation:

Kilometers per mile times miles gives kilometers.

(1.6 kilometers / mile) × M miles = 1.6M kilometers

5×1.6 is 8

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have

the rocket cannot penetrate the ground, in a contextual sense, therefore the roots of this equation should be the domain of this function. i'll let you find the roots of this quadratic equation (hint: use the quadratic formula:  

1- c

2-a
