-Convert the 1's complement 10111010 to decimal
frez [133]

Answer:

69

Explanation:

We are given a 1's complement of a number.So to convert it to the original number we have again take the 1's complement of the given 1's complement to convert it to the original number.We can do that by converting all 0's to 1's adn all 1's to 0's.

1's complement= 10111010

original number=01000101

Then to convert the binary number to the decimal number we have multiply each bit with the respective exponent of 2.The exponent of the LSB is 0 and it increases as we move to MSB by 1.

So the calculations are as  following:-

(01000101)₂ = (0 × 2⁷) + (1 × 2⁶) + (0 × 2⁵) + (0 × 2⁴) + (0 × 2³) + (1 × 2²) + (0 × 2¹) + (1 × 2⁰) = (69)₁₀

Sauron [17]

Answer:

import math

angle = float(input('Enter Angle: '))

shadowLength = float5(input('Enter Shadow Length: '))

tree_height = math.tan(angle)*shadowLength

print('Tree Height = {}'.format(tree_height))

Explanation:

From the equation given, the first step is to derive the equation for calculating the Tree Height.

tan(angleElevation) = tree height / shadow length\\\\tree height = tan(angleElevation) * shadow length

In order to calculate the tangent of an angle, the math module has to be imported. math module allows the program to perform advanced math operations.

The program then prompts the user to input values for angle and shadow length.

The inputted values are converted to floats and used in the equation that was derived for Tree height.

Three height is evaluated and the result is printed to the screen

I think you should do what are passionate about. therefore it might gain more followers. Also so it's not boring and it's enjoyable for you. also it will be easier for you to do. the pros are you will put in extra efforts, it will make you happy, it will workout longer, it can help you grow as a person. the cons are you may lose followers, it may be hard to think of content, you might not make money, people may try to bring you down.

i think you should make a different account and try it. either make another account for art or make another for vlogs.

But honestly just try it out and see how it goes.
