Using proportions, it is found that 400 light years have $3.6 \times 10^{18}$ meters.

To find how many meters are 400 light years, we use proportions, with a rule of three.

One light year has $9 \times 10^{15}$ meters.
How many meters are there in 400 light years, which in scientific notation, is $4 \times 10^2$ light years?

The<u> rule of three</u> is:

1 light year - $9 \times 10^{15}$ meters.

$4 \times 10^2$ light years - x meters

Applying cross multiplication:

$x = 9 \times 10^{15} \times 4 \times 10^2 = 36 \times 10^{17} = 3.6 \times 10^{18}$

Thus, 400 light years have $3.6 \times 10^{18}$ meters.

Imagine that you are planning to estimate the price of the average book at your college bookstore. The bookstore carries 13,000

mafiozo [28]

Answer: "13,000 books" represents the population.

"200" books represents the sample.

Step-by-step explanation:

A population is the term that denotes a whole large possible group of individuals, objects, events or measurements.
A subset of population is known as ample.
When population is too large to the researcher , then it uses sample to represent the entire population.

Here, "13,000 books" represents the population.

"200" books represents the sample which is a subset of 13,000 books.

Determine the maximum number of zeros. Then, determine the x-intercepts of the function. x^3-3x^2-22x+24

JulijaS [17]

Answer:

Three zeros $x=-4,\ x=1,\ x=6$

x-intercepts: (-4,0), (1,0), (6,0)

Step-by-step explanation:

Plot the graph of the function $y=x^3-3x^2-22x+24$ on the coordinate plane. This graph intersects the x-axis at three different points (see attached diagram):
