The sum of the interior angles, s, in an n-sided polygon can be determined using the formula s = 180(n – 2), where n is the numb

disa [49]

Answer:

Equivalent equation of $s =180(n-2)$ is $n =\frac{s}{180}+2$

And the number of sides does a polygon have is, n =9.

Step-by-step explanation:

Given:

The sum of the interior angles, 's' in a n-sided polygon can be determined

using the formula is: $s =180(n-2)$ .....[1]

where n is the number of sides.

We can write the equivalent equation of [1]

$s = 180(n-2)$

Divide both sides by 180;

$\frac{s}{180} =\frac{180(n-2)}{180}$

Simplify:

$\frac{s}{180}=n-2$

Add 2 to both sides of an equation:

$\frac{s}{180}+2=n-2+2$

Simplify, we get;

$n =\frac{s}{180}+2$ ......[2]

Now, to find the value of n ;

Given: s =1260°

Substitute this value in [2] we get;

$n =\frac{1260}{180}+2$

n = 7+2 =9

Therefore, the number of sides in a polygon is, n=9

Identify the best big-O estimate for the number of comparisons used by the algorithm that determines the number of 1s in a bit s

Westkost [7]

Answer:

0(n)

Step-by-step explanation:

Result previous exercise:

procedure count(a1a2...an : string with n > 1)

i:=0

for k:=1 to n

if ak =1 then i:=i + I

return i

Note: If you use a different algorithm, then you could possible get different results.

SOLUTION

There is only one part of the code that contains an operation (comparison), namely if a_k =1

This comparison is executed in every iteration of the for-loop

k can take on the values from 1 to n (for k:=I to n), thus k can take on n values.

Thus in total there are then n comparisons, while n is 0(n).

Logarithmic and Exponential Forms of Equations In Exercise, write the logarithmic equation as an exponential equation, or vice v

gavmur [86]

Answer:

$\log_e(4.4816) = 1.5$

Step-by-step explanation:

We are given the following in the question:

$e^{1.5} = 4.4816...$

We have to convert this equation into logarithmic equation.

Relation between exponent and logarithmic:

Logarithmic functions are the inverses of exponential functions.

The logarithmic function $y = \log_ax$ is defined to be equivalent to the exponential equation $x = a^y$

For the given expression a = e, y = 1.5 and x = 4.4816...

We can express them as:

$e^{1.5} = 4.4816...\\\text{Taking log on both sidses}\\\log(e^{1.5}) = \log(4.4816)\\\log_e(4.4816) = 1.4998 \approx 1.5\\\log_e(4.4816) = 1.5$
