A certain animated movie earned $1.1⋅109\$1.1 \cdot 10^9 $1.1⋅10 9 dollar sign, 1, point, 1, dot, 10, start superscript, 9, end superscript in revenues at the box office. The movie lasts 9.1⋅1019.1\cdot10^1 9.1⋅10 1 9, point, 1, dot, 10, start superscript, 1, end superscript minutes. How much revenue was earned per minute of the movie? Write your final answer in scientific notation, and round to two decimal places.

$ 1.21 * 10⁷ per minute

Movie Earning = $ 1.1 * 10⁹

Movie lasted for = 9.1 * 10¹ minutes

Money earned in 9.1 * 10¹ minutes = $ 1.1 * 10⁹

Money earned in 1 minutes =  $ 1.1 * 10⁹ / (9.1 * 10¹)

= $ 110 * 10⁷ / (9.1 * 10¹)

= $ 12.09 * 10⁶

= $ 1.209 * 10⁷

= $ 1.21 * 10⁷

Movie earning =   $ 1.21 * 10⁷ per minute

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
