I believe A is the answer

For this case, they ask us which of the given numbers, in scientific notation, is greater.

So:

6.23 * 10 ^ {12} = 6,230,000,000,000 is equivalent to rolling the decimal 12 times to the right.

6.23 * 10 ^ 8 = 623,000,000 is equivalent to rolling the decimal 8 times to the right.

6.23 * 10 ^ {-6} = 000000623 is equivalent to rolling the decimal 6 times to the left.

6.23 * 10 ^ 3 = 6,230 is equivalent to rolling the decimal 3 times to the right.

Thus, we observe that the greatest number is 6.23 * 10 ^ {12}

Answer:

Option A

Expand and combine like terms.<br> (3c^4-5c^6)^2
lora16 [44]

Answer:

9c^{8} -30c^{10} + 25c^{12}

Step-by-step explanation:

We can use formula (a-b)² = a² -2ab + b².

In our example a = 3c^4 and b = 5c^6

(3c^{4} - 5c^{6})^{2} = [3c^{4} ]^{2} - 2*3c^{4} *5c^{6} + [5c^{6}]^{2}=\\=9c^{8} -30c^{10} + 25c^{12}

Every employee works 7 hours per day. every employee works 5 days per week. every employee works 49 weeks per year. how many day
andriy [413]
To determine the number of days that an employee work in a week, we simply use dimensional analysis and multiplying the number of works per week with the number of weeks in total for a year. That is,
                         employee works = (5 days per week)(49 weeks per year) 
                                                    =245 days

Write the equation of the line that passes through the point (3,5) and is perpendicular to the line y=3.
3241004551 [841]

Answer:

x = 3

Step-by-step explanation:

y = 3 is the equation of a horizontal line parallel to the x- axis.

A line perpendicular to it must therefore be a vertical line parallel to the y- axis with equation

x = c

where c is the value of the x- coordinates the line passes through.

The line passes through (3, 5) with x- coordinate 3 , thus

x = 3 ← equation of perpendicular line
