Answer: 9.2

Step-by-step explanation:

   To find the average, add together all values and divide by the number of values.

  Suzy:

\displaystyle \frac{9.4+8.7+9.5}{3} =\frac{27.6}{3} =9.2

  Tammy:

\displaystyle \frac{9.5+9.2+8.9}{3} =\frac{27.6}{3} =9.2

     The average for both of their scores was 9.2.

In the equation f(x) = (3x + 5) (x2 - 6x + 9)2 = 0, 3 has a multiplicity of ______.
Svetradugi [14.3K]
Multiplicity is how many times the root (or zero) is repeated

example, in f(x)=a(x-b)^n(x-d)^m... the root b has a multiplicity of n and the root d has a multiplicity of m

first we need to get the roots into f(x)=a(x-b)^n(x-d)^m
for (3x+5), we need to force factor out the 3 to get
3(x+\frac{5/3})

factor the other one
(x^2-6x+9)=(x-3)(x-3)=(x-3)^2
but it is (x^2-6x+9)^2 which is equivilent to ((x-3)^2)^2 which simplifies to (x-3)^4

so we get
f(x)=3(x+\frac{5}{3})(x-3)^4
so the roots are -5/3 multiplicity 1 and 3 multiplicity 4


3 has a multilicity of 4
