Does anyone know what the √2.25 is when rewritten as a fraction?
Zinaida [17]

Answer:  \sqrt{\frac{9}{4} }

Step-by-step explanation:

This is what it is as a mixed number

\sqrt{2.25}

= \sqrt{2\frac{1}{4} }

= \sqrt{\frac{9}{4} }

If you want it written in exponential form it would look like this:

(\frac{9}{4}) ^{\frac{1}{2} }

Helen [10]

Answer:

y= 1/12(x-0)^2+0

this answer works as an upward parabola

Step-by-step explanation:

  • The formula for a veritcal parabola is y=1/4p(x-h)^2+k
  • (h,k)= coordinates of the vertex of the parabola
  • p= absolute value of the distance from the vertex to the focus/directrix
  • In this problem, it is given that the vertex is at the origin (0,0) and the focus (the bulb), is 3 centimeters away from the vertex.
  • Now, you know the values of the variables. Fill in the values
  • FROM THE FORMULA: 1/4p turns into 1/12 since p is 3.
  • (x-h)^2+k turns into (x-0)^2+0, since h and k where the values of the vertex which was 0,0
  • once all the variables are given values (except x and y) you have made your equation!
  • The answer is y=1/12(x-0)^2+0

Hey there :)

( 5y + 9 )( 6y - 1 )

We need to use FOIL to expand, that is
First Terms
Outer Terms
Inner Terms
Last Terms

     First          Outer         Inner      Last
( 5y )( 6y ) + ( 5y )( - 1 ) + 9 ( 6y ) + 9 ( - 1 )
    30y²     -        5y      +    54y   -       9

Combine, if any, the like-terms
30y² + 49y - 9
