Answer

15.7 meters squared.

Step-by-step explanation:

First you have to find the area of the small circle, using the formule A = 3.14(radius squared). So, 3.14(4) =12.56. Then you have to find the area of the bigger circle. A = 3.14(3 squared). A = 3.14(9) = 28.26. Finally, you subtract the area of the smaller circle from the bigger circle. 28.6 meters - 12.56 meters = 15.7 meters squared.

How many complex roots does the polynomial equation have? 3x5−2x+1=0

dmitriy555 [2]

Answer : The given polynomial equation can have 0,2 or 4 complex roots.

Explanation:-

Given polynomial equation is $3x^5-2x+1=0$ which is a polynomial of degree 5.

We know that the complex roots always occur in pair ,therefore the number of complex roots in any polynomial must be an even number but less than equal to the degree of polynomial.

Thus, the given polynomial equation has 4 complex roots.

There is a 1/3 chance of the spinner hitting any letter then the next time it would be another 1/3 chance. You multiply these together and get 1/9 but this is not the answer because there is 1/9 of BOTH happening so you add 1/9 plus 1/9 and get 2/9. The answer is 2/9.

Which statement is true regarding the graphed functions?

Vladimir79 [104]

let's analyze each case to determine the solution

case 1) f(0) = 2 and g(–2) = 0

For x=0-----> find the value of f(0) in the graph-----> f(0)=4

For x=-2-----> find the value of g(-2) in the graph-----> g(-2)=0

therefore

the statement of the case 1) is false

case 2) f(0) = 4 and g(–2) = 4

For x=0-----> find the value of f(0) in the graph-----> f(0)=4

For x=-2-----> find the value of g(-2) in the graph-----> g(-2)=0

therefore

the statement of the case 2) is false

case 3) f(2) = 0 and g(–2) = 0

For x=2-----> find the value of f(2) in the graph-----> f(2)=0

For x=-2-----> find the value of g(-2) in the graph-----> g(-2)=0

therefore

the statement of the case 3) is true

case 4) f(–2) = 0 and g(–2) = 0

For x=-2-----> find the value of f(-2) in the graph-----> f(-2) is greater than 12

For x=-2-----> find the value of g(-2) in the graph-----> g(-2)=0

therefore

the statement of the case 4) is false

therefore

the answer is

f(2) = 0 and g(–2) = 0-------> this statement is true
