Answer:

5,024 inches squared

Step-by-step explanation:

Since the area of a circle is pi r^2, we basically have to replace the r with 40, since it's the radius. Therefore when replaced, it would be pi(40)^2. This makes 1600pi. Pi is technically 3.14, so I multiplied 3.14 and 1600 to get 5,024 inches squared.

Answer:

The graph in the attached figure N 2

Step-by-step explanation:

The complete question in the attached figure N 1

we have the ordered pairs

(-4,9),(-1,3),(0,1),(2,-3)

Using a graphing tool

Plot the given ordered pairs in the coordinate plane

Remember that

In a ordered pair (x,y), the first coordinate is the location of the point in the x-axis and the second coordinate is the location of the point in the y-axis

see the attached figure

The graph represent a line

<em>Find the equation of the line</em>

<em>Find the slope</em>

take two points

$(0,1),(2,-3)\\m=(-3-1)/(2-0)=-2$

The equation of the line in slope intercept form is equal to

$y=mx+b$

we have

$m=-2\\b=1$

substitute

$y=-2x+1$

Find the area below

Katyanochek1 [597]

Answer:

A = 693

Step-by-step explanation:

The shape presented is a parallelogram, and the formula for this is:

A = bh

The "b," is the base (21) and the "h," is the height (33), so plug this in:

A = (21)(33)

A = 693

Given :f(x) =1/x+5 and g(x) =x-2 What are the restrictions of the domain of f(g(x))?

emmainna [20.7K]

I don't know if it's (1/x )+ 5 or 1/(x+5) anyways
g(x) = x-2 so in f(g(x)) you replace every x with x-2
f(g(x)) = (1/(x-2)) + 5 or 1/(x-2-5) = 1/(x-7)
if the function is like the first form so you avoid numbers which will make your denominator equals zero
x-2 = 0, x=2 or x-7 = 0, x=7
so if it's like first one answer is R - 2
if it's second answer is R - 7
