Answer:

64 π inches^2  or 201.06 inches^2  to the nearest hundredth.

Step-by-step explanation:

The radius = 1/2 * the diameter

= 1/2 * 8

= 4 inches.

The surface area = 4 π r^2

4 π 4^2

= 64 π inches^2

or  201.06 inches^2  to the nearest hundredth.

Find the first four iterates of the function f(x) = x2 with an initial value of x0 = -1.
jasenka [17]

Option A: 1,1,1,1 is the right answer

Step-by-step explanation:

In finding the function iterates we start with the initial value and put the initial value into the function and then the output of previous iterate is used as input for next iterate

Given

f(x) = x^2\\and\\x_0 = -1

<u>First iterate: </u>

Putting x=-1 in the function

f(-1) = (-1)^2\\=1

<u>Second iterate:</u>

Putting x=1

f(1) = (1)^2\\=1

<u>Third iterate:</u>

Putting x=1

f(1) = (1)^2\\=1

<u>Fourth iterate:</u>

Putting x=1

f(1) = (1)^2\\=1

First four iterates of given function with initial value -1 are: 1,1,1,1

Hence,

Option A: 1,1,1,1 is the right answer

Keywords: Functions, iterates

1. If 5x + 6 = 10, what is the value of 10x + 3?
Digiron [165]
Here the question is simple.
All because, we only need to find the value of x.
We are given two equations.
5x + 6 = 10 and 10x + 3 =?
So, we will find the the value of x in the first equation, so that we can substitute the value of x in the second one and there we are with the answer.
5x + 6 = 10
For finding the value of x, all we have to do is,
Transpose the number 6 to 10
Therefore. 5x = 10 - 6 ( Take the equal sign as The Magic Bridge on which if anyone crosses it , will change its sign.)
So we have,
5x = 4
So x = 4/5 ( Multiplication will change to division after crossing the equal sign)
( Doubtful? Substitute the value of x and try!)
Now that we got the value of x,
We can just simply substitute the value of x in the second equation.
10x + 3 = ?
x = 4/5
10*4/5 +3 => 5 and 10 get canceled to 2 at the numerator.
By normal multiplication and then addition, we will get,
8 + 3 = 11
Hope this helps!!!! :)
