The intersecting chords theorem states that whenever two chords intersect, the product of their pieces is constant.

So, in this case, we have

\overline{RW}\cdot\overline{WP}=\overline{SW}\cdot\overline{WQ}

Plugging your values, we have

8\cdot 9 = 6x \cdot 12x \iff 72=72x^2 \iff x^2=1

This equation has solutions x=\pm 1, but we can't choose x=-1, because it would lead to

\overline{SW}=-6,\quad\overline{WQ}=-12

So, the only feasible solutions is x=1

Which expression is equivalent to find f(0)<br> f(x) = -9 (3) ^x<br> f(0)=
ankoles [38]

x = 0

f(x) = -9(3)^0

Anything to the power of 0 is 1,

f(x) = -9(1)

f(x) = -9

The answer is -9

Hope this was useful :)

By coincidence, Kimberly's Paint Supplies sold equal quantities of two paint colors yesterday: yellow and blue. All yellow paint
Vlad1618 [11]

Answer:

36 liters

Step-by-step explanation:

We solve this question using the least common multiple method

Find and list multiples of the liter the blue paint comes in the liters the yellow paint comes in. We find the first common multiple is found. This is the least common multiple.

Multiples of 9:

9, 18, 27, 36, 45, 54

Multiples of 12:

12, 24, 36, 48, 60

Therefore,

LCM(9, 12) = 36

Hence, the smallest amount of each paint color the store must have sold is 36 liters
