First take 66(.75) to get the number she makes. then tripple that answer to get the number she makes total, as her mom is doubling it. think that if she makes $10, her mom would pay her $20, so she would have $30. just apply it to this problem set.

Graph the quadratic function <br> F(x)=3x^2+6x-24
Oliga [24]
For this case we have the following function:
 F (x) = 3x ^ 2 + 6x-24
 We observe that it is a quadratic equation.
 The graph is therefore a parabola.
 Its cut points are:
 (-4, 0)
 (2, 0)
 Answer:
 
See attached image to see graph of the function

two points on the line are (-10,1) and (5,-5).if the coordinate of another point on the line is -3,what is the x-coordinate?​
zlopas [31]

Answer:

x-coordinate = 0

Step-by-step explanation:

(-10,1) , (5,-5)

m = (y₂ - y₁)/(x₂ - x₁) = ( -5 - 1 ) / ( 5 - [-10] )

   = -6 / ( 5 + 10)

    = -6/15 = -2/5

y - y₁  = m (x - x₁)

y - 1 = (-2/5) ( x - [-10] )

y - 1 = (-2/5) ( x + 10 )

5 * (y -1)  = -2 (x + 10)

5y - 5 = -2x -20

2x + 20 + 5y  -5 = 0

2x + 5y + 15 = 0

Another point (a, -3) in on this line

2 * a + 5 * (-3) = -15

          2a -15    = -15

                  2a  = -15 +15

                 2a =  0

                    a = 0

x-coordinate = 0

Given: △ABC, m∠A=120°, AB=AC=1<br> Find: The radius of circumscribed circle
Citrus2011 [14]

In Δ ABC, ∠A=120°, AB=AC=1

To draw a circumscribed circle Draw perpendicular bisectors of any of two sides.The point where these bisectors meet is the center of the circle.Mark the center as O.

Then join OA, OB, and OC.

Taking any one OA,OB and OC as radius draw the circumcircle.

Now, from O Draw OM⊥AB and ON⊥AC.

As chord AB and AC are equal,So OM and ON will also be equal.

The reason being that equal chords are equidistant from the center.

AM=MB=1/2 and AN=NC=1/2  [ perpendicular from the center to the chord bisects the chord.]

In Δ OMA and ΔONA

OM=ON [proved above]

OA is common.

MA=NA=1/2  [proved above]

ΔOMA≅ ONA [SSS]

∴ ∠OAN =∠OAM=60° [ CPCT]

In Δ OAN

\cos60=\frac {AN}{OA}

\frac{1}{2}=\frac{\frac{1}{2}}{OA}

OA=1

∴ OA=OB=OC=1, which is the radius of given Circumscribed circle.
