Answer:

a) 11%

b) 56%

Step-by-step explanation:

a) A= πr^2    6^2π= 36π    A= 18^2π = 324π

36π/324π = .111111111111111111111111 or 11%

remember to cancel out the pi symbols when you are showing your work

(put a line across the pi symbols when dividing)

b)   A= πr^2         18^2 π = 324π

     A= πr^2          12^2π = 144π  

              324 – 144  = 180

180π/324π = .5555555555555555555555556 or 56%

Which polynomial function has a leading coefficient of 1 and roots 21 and 31 with multiplicity 1?
schepotkina [342]

Answer:

Which i think is the first one, there may just be a typing error.

Step-by-step explanation:

A polynomial of order n has the following format:

f(x) = a(x - x_{0})(x - x_{1})...(x - x_{n-1})

In which a is the leading coefficient, x_{0}, x_{1},..., x_{n-1} are the roots.

If a root appears m times, they are said to have multiplicity m.

Leading coefficient of 1 and roots 21 and 31 with multiplicity 1

f(x) = 1(x - 21)(x - 31)

So the correct answer is:

f(x) = 1(x - 21)(x - 31)

Which i think is the first one, there may just be a typing error.

Item 18
nasty-shy [4]

The first thing we have to do is to calculate the midpoint of the min and max speeds. We are given that the min and max is 74 and 95 respectively. The midpoint is then calculated as (max+min) / 2. Therefore:

midpoint = (74 + 95) / 2 = 84.5

 

Next, we calculate the distance from the midpoint to the endpoint by doing subtraction. Therefore:

min endpoint: 84.5 – 74 = 10.5

max endpoint: 95 – 84.5 = 10.5

 

Now we know that v minus the midpoint will equal the distance such that:

| v - midpoint | = distance.

To our problem,

| v – 84.5 | = 10.5
