State a definition for a polygon inscribed in a sphere.

Mathematics
1 answer:
mojhsa [17]3 years ago

Consider the situation given below:

Let a regular polygon be inscribed in a sphere such that its circumcentre is at a distance r from the centre of the sphere of radius R. A point source of light is kept at the centre of the sphere. How can we calculate the area of the shadow made on the surface of the sphere.

I tried to use the relation: <span>Ω=<span>S<span>R2</span></span></span>

But of course that is the case when a circle would be inscribed. So can I somehow relate it for any general polygon?

The 1997 a value of an object was $5000. In 2012, it was worth $9500. The annual percent growth has been constant. What is the a
Daniel [21]
<h3>Annual percent growth is 4.37 %</h3>

<em><u>Solution:</u></em>

<em><u>The increasing function is given as:</u></em>

y = a(1+r)^t

Where,

y is future value

a is initial value

r is growth rate

t is number of years

From given,

a = 5000

y = 9500

t = 1997 to 2012 = 15 years

r = ?

<em><u>Substituting the values we get,</u></em>

9500 = 5000(1+r)^{15}\\\\(1+r)^{15} = 1.9\\\\Take\ \frac{1}{15}th\ power\ on\ both\ sides\\\\1+r = (1.9)^{\frac{1}{15}}\\\\1+r = 1.04367\\\\r = 1.04367 - 1\\\\r = 0.04367\\\\In\ percentage,\\\\r = 0.04367 \times 100 \%\\\\r = 4.367 \% \approx 4.37 \%

Thus annual percent growth is 4.37 %

What is the simplified form of (3.25x10^3)(7.8x10^6) written in scientific notation?
BabaBlast [244]

Answer: 2.535*10^{10}


Step-by-step explanation:

1. By definition, scientific notation has the following form:

a*10^{b}

Where:

<em> a</em> is a number between 1 and 10 but does not include 10.

<em> b </em>an integer.

2. When you multiply 3.25 by 7.8  the result is 25.35 and when you multiply 10^{3} by 10^{6}, you obtain 10^{9}, but to write ree thsult in scientific notation, the decimal point must be after the first digit. Therefore, you must move the decimal point one place to the left. So, the exponent changes from 9 to 10:

(3.25*10^{3})(7.8*10^{6})=2.535*10^{10}

b=2(10)^2(10-5)/10(10

b=2(100)(5)/100

b=(200)(5)/100

B=2500/100

B=25

Find the measure of angle x. Round your answer to the nearest hundredth. (please type the numerical answer only)
Alex

The value of x in the triangle is 28.1 degrees

<h3>How to solve for x?</h3>

The given triangle is a right triangle.

So, the relationship between the sides and angle x is:

sin(x) = opposite/hypotenuse

This gives

sin(x) = 8/17

Evaluate the quotient

sin(x) = 0.4706

Take the arc sin of both sides

x = \sin^{-1}(0.4706)

Evaluate

x = 28.1

Hence, the value of x in the triangle is 28.1 degrees
