If f(x)=[x-5] 3 find f(2)

Answers

Answer 1
Answer:

The value of he function f(x) = (x - 5)³ at f(2) Or x = 2 is - 27.

What is a function?

A function can be defined as the outputs for a given set of inputs.

The inputs of a function are known as the independent variable and the outputs of a function are known as the dependent variable.

Given, A function f(x) = (x - 5)³, now this is an odd function as the exponent is odd and is symmetric about the origin.

Now at f(2) Or x = 2 we'll simply replace x with 2 in f(x).

∴ f(2) = (2 - 5)³.

f(2) = (-3)³.

f(2) = - 27.

What is the equation of the line that passes through (-6,-6) and (12,9)?

Answers

The correct answer for the question that is being presented above is this one: 

(1) Get the slope (m)
m = (y1 - y2) / (x1 - x2)
m = (-6 - 9) / (-6 - 12)
m = -15 / -18
m = 5/6

(2) Get the x-intercept (b)
y = mx + b
-6 = (5/6)(-6) + b
-6 = -5 + b
b = -1

(3) Form the equation
y = mx + b
y = (5/6)x -1

So the equation is y = (5/6) x - 1.

the rectangular floor of a classroom is 36 ft in length and 32 ft in width and scale drawing of the floor has a length of 9 inches what is the area in square inches of the floor in scale drawing​

Answers

72 square inches.

Start by finding the dimensions of the scale drawing. If 36 divided by a number equals 9, then that number is 4. 36 / 4 = 9

So, you need to divide 32 by 4 as well to get 8.

This means the scale drawing is 9 inches long and 8 inches wide.

Finally, to find the area, multiply the length and width together. 9 * 8 = 72

The area of the scale drawing is 72 square inches.
