Answer:

Shown Below

Step-by-step explanation:

The Whole number can be put over one to make multiplying easier.

1- 4/5 times 20/1 = 80/5= 16

2- 5/10 times 19/1= 95/10= 9.5

3- 2/3 times 6/1= 12/3= 4

4- 5/10 times 8/1= 40/10= 4

5- 4/6 times 16/1= 64/6= 10 2/3

6- 4/10 times 4/1= 16/10= 1 3/5

7- 2/8 times 15/1= 30/8= 3.75

8- 4/5 time 2/1= 8/5= 1.6

Determine the equation of the parabola whose graph is given below. Write your answer in General Form. A parabola on a coordinate

dimaraw [331]

The equation of parabola becomes y = -2/25(x-3)^2 + 4.

According to the statement

we have given a graph and from this graph we have to find the equation of parabola in the general form.

So,

we know that the equation of parabola in general form is

y = a(x-h)^2 +k - (1)

From the graph we have:

a point on the graph is (x,y) = (-2,2)

the vertex of the graph is (h,k) = (3,4)

Now, substitute these values in the equation number (1)

Then

y = a(x-h)^2 +k

2 = a(-2-3)^2 +4

2 = a(-5)^2 +4

2 = a(25) +4

25a = -2

a = -2/25.

Now put a = -2/25 and (h,k) = (3,4) in the equation(1).

Then

the equation of parabola becomes y = -2/25(x-3)^2 + 4

So, The equation of parabola becomes y = -2/25(x-3)^2 + 4.

Which explains why the graph is not a function?

german

The statements that apply to the ratio of rice and water are:

The ratio of rice to water is 1 to 2.5
The ratio of water to rice is 2.5 to 1

<h3>Ratios</h3>

Ratios are used to compare quantities of different measurements

The entries on the table are given as:

<u>Rice Water</u>

2 5

3 7.5

5 12.5

8 20

<h3>The ratios of both quantities</h3>

The ratio (r) of rice and water is then calculated as:

$r = \frac{Water}{Rice}$

Pick any corresponding table entry.

So, we have:

$r = \frac{5}{2}$

Divide

$r = 2.5$

This means that, the ratio of rice to water is 1 to 2.5, and the ratio of water to rice is 2.5 to 1
