Answer:

1 : 4

Step-by-step explanation:

half litre = 500 ml

Milk : water = 125 : 500

= 125 ÷ 25 : 500÷25

= 5 : 20

= 1 : 4

There are 2 cups in 1 pint. So you could count by 2s until you get to 14. Or you can multiply 14×2=28

Using the given information, give the vertex form equation of each parabola.

Amanda [17]

Answer:

The equation of parabola is given by : $(x-4) = \frac{-1}{3}(y+3)^{2}$

Step-by-step explanation:

Given that vertex and focus of parabola are

Vertex: (4,-3)

Focus:( $\frac{47}{12}$ ,-3)

The general equation of parabola is given by.

$(x-h)^{2} = 4p(y-k)$ , When x-componet of focus and Vertex is same

$(x-h) = 4p(y-k)^{2}$ , When y-componet of focus and Vertex is same

where Vertex: (h,k)

and p is distance between vertex and focus

The distance between two points is given by :

L= $\sqrt{(X2-X1)^{2}+(Y2-Y1)^{2}}$

For value of p:

p= $\sqrt{(X2-X1)^{2}+(Y2-Y1)^{2}}$

p= $\sqrt{(4-\frac{47}{12})^{2}+((-3)-(-3))^{2}}$

p= $\sqrt{(\frac{1}{12})^{2}}$

p= $\frac{1}{12}$ and p= $\frac{-1}{12}$

Since, Focus is left side of the vertex,

p= $\frac{-1}{12}$ is required value

Replacing value in general equation of parabola,

Vertex: (h,k)=(4,-3)

p= $\frac{-1}{12}$

$(x-h) = 4p(y-k)^{2}$

$(x-4) = 4(\frac{-1}{12})(y+3)^{2}$

$(x-4) = \frac{-1}{3}(y+3)^{2}$

PLEASE HELP ASAP. I need help with this problem, I've gotten two answers: 60 and 90 but I can't figure out which one it is. Plea

Find the ratio of the known sides.

6/4 = 1.5

The larger triangle is 1.5 times larger than the smaller one.

Area is in square units, so to find the area of the larger triangle square the ratio and multiply that by the area of the known triangle.

1.5^2 x 40 = 90 square cm.
