Multiplying the linear expressions, the correct sequence is given as follows:

  • 5x(-3 -7x)
  • (5x)(-3) + (5x)(-7x)
  • -15x - 35x²

<h3>How are linear expressions multiplied?</h3>

They are multiplied applying the distributive property, in which all the terms are multiplied and the like terms are combined.

Hence:

5x(-3 -7x)

(5x)(-3) + (5x)(-7x)

-15x - 35x²

Hence the last option is correct.

A circle has its center at the origin, and (5, -12) is a point on the circle. How long is the radius of the circle?
Amanda [17]

Option C

The radius of circle is 13 units

<em><u>Solution:</u></em>

<em><u>The equation of circle is given by formula:</u></em>

(x-h)^2+(y-k)^2 = r^2

Where, the center being at the point (h, k) and the radius being "r"

<em><u>Given that circle has its center at the origin</u></em>

(h, k) = (0, 0)

<em><u>(5, -12) is a point on the circle</u></em>

(x, y) = (5, 12)

<em><u>Substituting in equation we get,</u></em>

(5-0)^2+(12-0)^2 = r^2\\\\5^2+12^2 = r^2\\\\r^2 = 5^2+12^2\\\\r^2 = 25 + 144\\\\r^2 = 169\\\\Taking\ square\ root\ on\ both\ sides\\\\r = \sqrt{169}\\\\r = \pm 13\\\\Since\ radius\ cannot\ be\ negative\ ignore\ r = -13\\\\Thus\ the\ solution\ is:\\\\ \r = 13

Thus radius of circle is 13 units

What is the theoretical probability of getting heads? That's it nothing else just heads...is it like 50/50 shot? Or 1/2?
Dmitriy789 [7]
Answer: The theoretical probability of getting heads is just 50/50, you were right.

When you are flipping a coin, there are two equally likely possible outcomes. Only 1 of those outcomes is heads.

Therefore, the theoretical probability of getting heads is 1/2, or 0.5 or 50% or we often just say 50/50.
