3 0

Answer:

A

Step-by-step explanation:

Substitute x = f(x) into g(x), that is

g(f(x))

= g(3x² - 2x - 1)

= (3x² - 2x - 1)² = (3x² - 2x - 1)(3x² - 2x - 1)

Each term in the second factor is multiplied by each term in the first factor, that is

3x²(3x² - 2x - 1) - 2x(3x² - 2x - 1) - 1(3x² - 2x - 1) ← distribute parenthesis

= 9x^{4} - 6x³ - 3x² - 6x³ + 4x² + 2x - 3x² + 2x + 1 ← collect like terms

= 9x^{4} - 12x³ - 2x² + 4x + 1 → A

Find the distance between the coordinates (0, 4) and (10,4) and write the result in the empty box.
barxatty [35]

The distance between the coordinates (0, 4) and (10,4) is 10

Step-by-step explanation:

We need to find the distance between the coordinates (0, 4) and (10,4)

The formula used to find distance is:

Distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

where

x_1=0, y_1=4, x_2=10,y_2=4

Putting values:

Distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\Distance=\sqrt{(10-0)^2+(4-4)^2}\\Distance=\sqrt{(10)^2+(0)^2}\\Distance=\sqrt{(10)^2}\\Distance=10

So, The distance between the coordinates (0, 4) and (10,4) is 10

Find the median and mean of the data set below:<br> 21,0,36,30,13,32
UkoKoshka [18]

Answer:

Mean: 22

Median: 25.2

Step-by-step explanation:

The mean is the sum of all the numbers in a set divided by the number of terms in a set.

The median is the middle value of the numbers when the numbers in a set are arranged from least to greatest. If there is two middle numbers, the median is the average of the two numbers.

I hope this helps!
