Which fraction and equivalent decimal correctly shows the ratio of shaded circles to all circles?
sergeinik [125]
Shaded circles = 4
Total circles = 12

\frac{shaded~circles}{total~circles} = \frac{4}{12}

\frac{4}{12} as a simplified expression = \frac{2}{6}
We can simplify it even more = \frac{1}{3}

Fraction = \frac{1}{3}

Equivalent decimal = 1 ÷ 3 = 0.33

jenyasd209 [6]

Answer:

p = 7

Step-by-step explanation:

So the key is that a line has a measure of 180 degrees. Notice the square between the rays. That is a 90-degree angle. So let's add this up and see what's going on

(5p + 2) + 90 + (7p + 4) = 180

12p + 96 = 180

12p = 84

p = 7

Write an equation for the cubic polynomial functior
d1i1m1o1n [39]

So, the cubic polynomial function is x^3-10x^2+31x-30=0

No, none of the roots have multiplicity.

Step-by-step explanation:

We need to write an equation for the cubic polynomial function

whose graph has zeroes at 2, 3, and 5.

Zeros mean:

x=2, x=3 and x=5

or

x-2=0, x-3=0 and x-5=0

Multiplying all the factors:

(x-2)(x-3)(x-5)=0\\(x-2)(x(x-5)-3(x-5))=0\\(x-2)(x^2-5x-3x+15)=0\\(x-2)(x^2-8x+15)=0\\x(x^2-8x+15)-2(x^2-8x+15)=0\\x^3-8x^2+15x-2x^2+16x-30=0\\x^3-8x^2-2x^2+15x+16x-30=0\\x^3-10x^2+31x-30=0\\

So, the cubic polynomial function is x^3-10x^2+31x-30=0

No, none of the roots have multiplicity, A root has multiplicity if it appears more than 1 time. Like if (x-1)^2 is a root then 1 has multiplicity 2
