3 0

Answer:

31:21

Step-by-step explanation:

3/5 = 0.6. multiply both number by 0.6 to get 24 and 7.2 now you cannot have part of a win or a loss that makes no sense. so round it and you get 24 and 7 add those together to get 31. subtract 31 from 52 to get 21. he had 31 wins and 21 losses.

Construct a polynomial function with the following properties: fifth degree, −2 is a zero of multiplicity 2, 4 is the only other
CaHeK987 [17]
5th degree means highest power is 5 total

zeroes/roots are
(x-r)
so -2 is a root
(x-(-2))
(x+2) is a root
multiplicity 2 means it happens 2 times ie
(x+2)^2
e
4 is the only other zero
(x-4)

so now we have
(x-4)(x+2)^2
but that is only 3rd degreed
I could add 2 more degrees that are complex roots and therefor won't be graphed on the plane since they are complex so
find a 2nd degree polynomial that has only complex roots
a complex 2nd degree polynomial
x^2+x+10

ok so this is the function
f(x)=(x-4)(x+2)^2(x^2+x+10)

Graph the following piecewise function.
atroni [7]

Answer:

The graph of this piece-wise function is attached below.

Step-by-step explanation:

Given the function

{\displaystyle f(x)={\begin{cases}x^{2} +2&{\text{if }}-5\leq x

  • A piece-wise function is a function which has multiple pieces.
  • Each of the pieces have their own restrictions.
  • The domain of a function is the set of input, or x, values for which the function is defined.
  • The range is the set of all values taken by the function

As the piece

f(x)=x^{2} +2 has the domain [-5, 3) and graph of this piece is attached below.

and

f(x)=x-4 has the domain [3, 7) and graph of this piece is attached below.

So, the domain of the piece-wise function can be composed as [-5, 3) U [3, 7) and range has the interval \:\left[-1,\:27\right].

i.e.

Domain: [-5, 3) U [3, 7)

Range: \:\left[-1,\:27\right]

The graph of this piece-wise function is attached below.
