The minimum distance from Earth to Mars is shown below. What is the distance in scientific notation?
34,000,000 miles
A 3.4 x 10-7 mi
B
3.4 x 106 mi
C
3.4 x 10? mi
D
3.4 x 108 mi

A: 3.4 x 10^7

Step-by-step explanation:

    To write an answer in scientific notation you need to move the zero so that there is one number in front of it. Then you multiply that number by how many zeroes it would be to get the number back to its original form.

    In this case we are moving the zero 7 digits to the left to make the number 3.4.  And since the number was originally bigger it would be times a positive ten to the power of seven, so your answer would be A: 3.4 times 10 to the power of 7.

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

d is the answer
