Answer:

(i) 8.5 × 10^-12

(ii)  9.42 × 10^-12

(iii) 602 × 10^15

(iv) 8.37 × 10^-9

  

(v) 3.186 × 10^10

Step-by-step explanation:

(i) 0.0000000000085

= 0.0000000000085 × 10^12/10^12 

= 8.5/10^12 

<u>= 8.5</u><u> </u><u>×</u><u> </u><u>10^-12</u>

(ii) 0.00000000000942

= 0.00000000000942 × 10^12/10^12 

= 9.42/10^12 

<u>= 9.42</u><u> </u><u>×</u><u> 10^-12</u>

(iii) 6020000000000000

<u>= 602 </u><u>×</u><u> </u><u>10^15</u>

(iv) 0.00000000837

= 0.00000000837 × 10^9/10^9 

= 8.37/10^9 

<u>= 8.37</u><u> </u><u>×</u><u> </u><u>10^-9</u>

  

(v) 31860000000

<u>= 3.186 </u><u>×</u><u> 10^10</u>

The distance between Columbus,Ohio and New York City is about 560 miles how many hours would it take the train to travel between
sergey [27]
Since the distance is 560 miles and the bus goes 268 miles per hour, the answer can be given as:
If 268=1 hour
  560=?
560/268*1 hour =2(rounded to nearest ones)
Therefore it will take the train approximately 2 hours to travel between both cities.

Answer:

  y < -1/4x -1

Step-by-step explanation:

The boundary line appears to go through the points (-4, 0) and (0, -1). This tells you it has a "rise" of -1 for a "run" of 4. The slope is ...

  m = rise/run = -1/4

The y-intercept (b) is the point where the y-axis is crossed. The slope-intercept equation of the boundary line is ...

  y = mx + b

  y = -1/4x -1

__

The boundary line is dashed, so is not included in the solution set. The shading is below the line, so all y-values less than (but not equal to) the boundary line are in the solution set:

  y < -1/4x -1

Slope of line that passes through points (2,1) and (17,-17)
mojhsa [17]

Answer: y = -1,2x + 3.4

Step-by-step explanation:

y = ax + b

(2,1)      => 1    = 2a + b (1)

(17,-17) => -17 =17a + b (2)

Using caculator Mode => 5 =>1

We get : a=- 1.2 , b = 3.4

=> y = -1.2x + 3.4
