Given two points A and B, lines from them to center of the circle form the central angle∠<span>AOB. The central angle is the smaller of the two at the center. It does not mean the </span>reflex angle ∠<span>AOB. As you drag the points above, the angle will change to reflect this as it increases through 180°.
</span>Identify the inscribed angle<span> and </span>central angle<span> subtended by the same arc. </span>Recognize<span> that the </span>central angle<span> is twice the measure of the inscribed </span>angle<span> subtended by the same arc. Identify the tangent(s) to a</span>circle<span>. Identify the point of tangency on a </span><span>circle</span>

Evaluate the function found in the previous step at X =-3
babunello [35]
x-5y=-4x-2y

In order to evaluate the given function at x = -3, simply replace "x" in the function with -3 and solve.

-3-5y=-4(-3)-2y

<em>Multiply -4 and -3 in the function above.</em>

-3-5y=12-2y

<em>Add 3 on both sides of the equation.</em>

-3-5y+3=12-2y+3-5y=15-2y

<em>Add 2y on both sides of the equation.</em>

-5y+2y=15-2y+2y-3y=15

<em>Divide both sides of the equation by -3.</em>

\frac{-3y}{-3}=\frac{15}{-3}y=-5

Therefore, at x = -3, the value of y = -5. Hence, f(-3) = -5.

Answer:

f(-3) = -5

Indicate in standard form the equation of the line through the given points.
Molodets [167]

Answer:

x-y=4

Step-by-step explanation:

(y+4)/(1+4) = x/5

(y+4)/5 = x/5

y+4 = x

-x+y= -4

x-y = 4

We want to find the zeros of this polynomial:<br> p(x)= 3x^3 – 3x^2– 18x
bulgar [2K]

Answer:

x=0   x=3   x=-2

Step-by-step explanation:

p(x)= 3x^3 – 3x^2– 18x

Factor out the greatest common factor, 3x

p(x)= 3x (x^2 – x– 6)

Factor inside the parentheses

What 2 numbers multiplies to -6 and adds to -1

-3*2 = -6

-3+2 = -1

p(x)= 3x (x-3)(x+2)

Setting the function equal to zero to find the zeros

0 = 3x (x-3)(x+2)

Using the zero product property

3x = 0  x-3 =0   x+2 =0

x=0   x=3   x=-2
