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 = 4n^{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.

Plz help me!!<br><br> Step by step to understand the answer plz
Doss [256]

Answer:

2/3

Step-by-step explanation:

so the inverse takes us from the range to the domain... they tell us that  f(4) goes to 5.. so if we were to take the inverse  f\left \[-1} \atop(5)  it takes us back to 4... and the slope at 4 or the derivative was 2/3 so that's what we get for f\left \ {{-1} \atop '(5)  :)

Graph both functions to find the solution(s) to the system.
BaLLatris [955]

   <span> f(2) = 2×2 − 1 = 3</span>

The point of intersection is (2, 3).

The example shows that we can find the point of intersection in two ways.
Either graphically, by drawing the two graphs in the same coordinate system, or algebraically by solving the equation such as the one in the above example.

<span>Solving an equation graphically is easy with a graphical calculator or a computer program such as Excel.
Some equations cannot be solved algebraically but we can find solutions that are correct to as many significant figures as we want by using computers and calculators</span>
