Answer:
147.2 × 10 raised to the 6th power.
Step-by-step explanation:
First you have to convert them normal numbers. The first one is 46,000. The second one is 3,200. The four and three help to indicate the number of zeros behind that 1. 4.6 times 10000 would be 46000. (move the decimal to the right).
Then after multiplying the numbers you have to convert them back to scientific notation. Write the number out, 147,200,000. Then slice the decimal right in between 7 and 2 to form a decimal with only a tenths place. Count how many places there are to the end, and that will be the exponent you will use.
To check answer convert to number.

Answer:
Profit P(x) = 53x-12 and On selling 20 video games profit will be 1048.
Step-by-step explanation:
In the given question functions are Revenue function : R(x) = 60x and Cost function : C(x) = 12+7x for the sale of x video games
As we know profit = sale price - cost price
Therefore P(x) = R(x) - C(x)
Or P(x) = (R-C)x = 60x - (12+7x)
P(x) = 60x -12 - 7x
P(x) = 53x -12
Now the profit on selling 20 video games will be
P(20) = 53×20 -12 = 1060 -12 = 1048.
X is equal to 2. The steps are listed below :)
Answer:
-3x² +6x -1 = 0
Step-by-step explanation:
x2 - 2x + = 4(x2-2x +1)-3
x² - 2x = 4x²-8x +4 - 3
x²-4x²-2x+8x = 4-3
-3x² +6x = 1
-3x² +6x -1 = 0
