Maximum value : x=-4

The graph of the parabola opens down, since the value of a (-2) is a negative coefficient. This means the parabola has a maximum value, not a minimum value. The vertex of the parabola is -4, which is the maximum value of the graph.

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

Suppose a white dwarf star has a diameter of approximately 1.8083 to the power of 4 km. Use the formula 4n to the power of 2 to

aivan3 [116]

ANSWER:

The surface area of the star is 3.2700 x $10^{8}$ square kilometres.

EXPLANATIONS:

Diameter of the star = 1.8083 x $10^{4}$ Km.

Surface area of the star = 4 $n^{2}$

Where n is the radius of the star.

So that;

n = $\frac{ 1.8083 * 10^{4} }{2}$

= 0.90415 x $10^{4}$

n = 0.90415 x $10^{4}$ Km

Thus,

Surface area = 4 x $(0.90415*10^{4} )^{2}$

= 326994889

Surface area = 3.2700 x $10^{8}$ $km^{2}$

Therefore, the surface area of the star is 3.2700 x $10^{8}$ square kilometres.

What is the domain of the function y=√4x+8<br> Can you show your work too, please? (:

kirill115 [55]

$y= \sqrt{4(x+2)}$
$y = 2 \sqrt{x+2}$

The domain would be -2, the x-intercept.
