Answer:
The standard equation of the parabola is:

Step-by-step explanation:
An x intercept of 2 means that the point (2, 0) is in the graph of the parabola.
We can also write the general expression for the parabola in vertex form, since we can use the information on the coordinates of the vertex: (4, 6) - recall that the axis of symmetry of the parabola goes through the parabola's vertex, so the x-value of the vertex must be x=4.

Now we can find the value of the parameter "a" by using the extra information about the point (2, 0) at which the parabola intercepts the x-axis:

Then the equation of the parabola becomes:

Short answer: 375 grams
Remark
You only need to set up a direct proportion
Givens
flour for 12 cakes = 150 grams
Number of cakes initially = 12
Amount of flouer for 30 cakes = x
Number of cakes = 30
Proportion
amount flour for 12 cakes / 12 cakes = x / 30
Sub and solve
150 grams / 12 cakes = x / 30 cakes Cross multiply
150 * 30 = 12 *x Multiply the left side.
4500 = 12 x Divide both sides by 12
4500/12 = x
375 grams for 30 cakes. <<<<< Answer
Answer:
113.04 cm
Step-by-step explanation:
We know the formula to find the area of a circle is

And we are told to use 3.14 instead of pi so what we have now is,

We are also told the radius, r, is 6. So our equation now looks like this,
is the same as 36, because 6x6 is 36.
Now we have,
Which equals 113.04 and that is the area!
Hope that helps and have a great day!
Answer:
your y-intercept is 0 and slope is 4 so any line with zero slope it will be horizontal
