Answer:

Step-by-step explanation:

radius squared multiplied by pi = area

2 squared = 4

3.14 x 4 = 12.56

Area= 12.56 feet squared

Answer:

It is 12.57 ft^2.

Step-by-step explanation:

Use the formula A=πr2

Pi is about 3.14.

Do r^2 first to get 2^2=4.

4*3.14=12.566 and you can round up the decimal.

Find the inverse of each function. Is the inverse a function? y=(x+4)³-1
tatuchka [14]

Inverse of the give function F(x) = ( x + 4 )³ - 1 is F⁻¹(x) = [√( x + 1 ) ] - 4.

Given is a function of x, F(x) = ( x + 4 )³ - 1

These question can be solved by following 4 easy steps

Step 1 : Switch the F(x) with the variable y

This implies, F(x) = ( x + 4 )³ - 1 becomes y = ( x + 4 )³ - 1

Step 2 : Interchange the variable x and y in the above obtained equation

This implies, from the equation y = ( x + 4 )³ - 1, we get

x = ( y + 4 )³ - 1

Step 3 : Solve the new obtained equation for y

This implies, we have to simplify the equation by rearranging the terms to get the equation in terms of the variable x.

x = ( y + 4 )³ - 1

=> x + 1 = ( y + 4 )³

=>  (y + 4 )³ = x + 1

=> y + 4 = √( x + 1 )

=> y = √( x + 1 ) - 4

Hence we obtain the required equation.

Step 4 : Switch the variable y with F⁻¹(x)

This implies, y = √( x + 1 ) - 4 becomes F⁻¹(x) = √( x + 1 ) - 4

Therefore, we get the inverse of the give function F(x) = ( x + 4 )³ - 1 as F⁻¹(x) = [√( x + 1 ) ] - 4.

Compute the exact value of the function for the given x-value without using a calculator. f(x) = 4x for x = -1
bija089 [108]
So when x = -1, you just substitute the variable x to -1.

"4x" means 4 times x, so when x is replaced to -1, that would be 4 times -1.

f(-1) = 4(-1) = -4

So the value of function at x = -1 would be -4.

Hope this helps.

To solve 493x = 3432x 1, write each side of the equation in terms of base.
iVinArrow [24]

The solution of the equation in terms of the base is \rm x = \dfrac{-1}{2939}\\\\.

Given that

Equation; \rm 493x= 3432x+1

We have to find

The solution of the equation in terms of base.

According to the question

To determine the solution of the equation following all the steps given below.

Equation; \rm 493x= 3432x+1

Then,

\rm 493x= 3432x+1\\\\493x-3432x=1\\\\-2939x=1\\\\x = \dfrac{-1}{2939}\\\\

Hence, the solution of the equation in terms of the base is \rm x = \dfrac{-1}{2939}\\\\.
