Scientific notation is basically a short cut to write numbers with a lot of zeros in them. The difference between 3^8 and 3*10^8 is that the first is 3 multiplied by itself 8 times, and the second is 3 being mulitplied by 10^8. I hope this helps.

Nataly_w [17]

C; A and B are incorrect because the shift is not vertical, it is horizontal. This is because 3 is in parenthesis or a 'grouping' (same thing if it is in an exponent) and is being modified. Since the graph is being translated down 3 units, D is incorrect since it is a translation up 3 units. The answer is C.

Marysya12 [62]

Answer:

The value of x is 8 .

Step-by-step explanation:

It is known that EF = x cm , GH = (x + 6) cm , RS = 16 cm and NP = 28 cm . Knowing that EF ,GH , RS , and NP are, in that order, proportional segments, determine the value of x .

As EF, GH, RS and NP are in proportion

So,

EF : GH = RS : NP

\frac{x}{x+6}=\frac{16}{28}\\\\7 x = 4 (x + 6)\\\\7 x = 4 x + 24 \\\\3 x = 24 \\\\x = 8

Vaselesa [24]

There are 12 more of white and blue cars than silver and red cars

Step-by-step explanation:

Step 1 :

Number of black cars counted by Ed = 23

Number of red cars counted by Ed = 9

Number of blue cars counted by Ed = 17

Number of white cars counted by Ed = 25

Number of silver cars counted by Ed = 21

We need to determine how many more white and blue cars are there than silver and red cars

Step 2  :

Total of white and blue cars = 25 + 17 = 42 cars

Total of sliver and red cars = 21 + 9 = 30 cars

Difference  = 42 - 30 = 12 cars

Hence there are 12 more of white and blue cars than silver and red cars

Step 3 :

Answer :

There are 12 more of blue and white cars than red and silver cars
