Answer:
Step-by-step explanation:
La energía mecánica total está dada por:
![E_{T} = E_{c} + E_{p}](https://tex.z-dn.net/?f=%20E_%7BT%7D%20%3D%20E_%7Bc%7D%20%2B%20E_%7Bp%7D%20)
![E_{T} = \frac{1}{2}mv^{2} + mgh](https://tex.z-dn.net/?f=%20E_%7BT%7D%20%3D%20%5Cfrac%7B1%7D%7B2%7Dmv%5E%7B2%7D%20%2B%20mgh%20)
En donde:
m: es la masa = 150 g
v: es la velocidad = 0.8 m/s
h: es la altura = 25 m
g: es la gravedad = 9.81 m/s²
![E_{T} = \frac{1}{2}mv^{2} + mgh = \frac{1}{2}0.15 kg*(0.8 m/s)^{2} + 0.15 kg*9.81 m/s^{2}*25 m = 36.84 J](https://tex.z-dn.net/?f=%20E_%7BT%7D%20%3D%20%5Cfrac%7B1%7D%7B2%7Dmv%5E%7B2%7D%20%2B%20mgh%20%3D%20%5Cfrac%7B1%7D%7B2%7D0.15%20kg%2A%280.8%20m%2Fs%29%5E%7B2%7D%20%2B%200.15%20kg%2A9.81%20m%2Fs%5E%7B2%7D%2A25%20m%20%3D%2036.84%20J%20)
Por lo tanto, la energía mecánica total es 36.84 J.

Step-by-step explanation: Because even if you rotate the picture if you fold it in half it will fit perfectly with each other
The probability that all of them will be defective is 0.0000759375
<em><u>Explanation</u></em>
The general <u>Binomial Probability</u> formula is....
, where p is the probability of success, n is the total number of trials and r is the desired numbers of trials.
Given, the probability that a computer will be defective is 0.15 , so p = 0.15
Five computers are manufactured and we need to find the probability that all of them will be defective. That means, n = 5 and r = 5
Now according to the above formula....
![P= ^5C_{5}*(0.15)^5*(1-0.15)^5^-^5 \\ \\ P= 1*(0.15)^5* (0.85)^0\\ \\ P=(0.15)^5 =0.0000759375](https://tex.z-dn.net/?f=P%3D%20%5E5C_%7B5%7D%2A%280.15%29%5E5%2A%281-0.15%29%5E5%5E-%5E5%20%5C%5C%20%5C%5C%20P%3D%201%2A%280.15%29%5E5%2A%20%280.85%29%5E0%5C%5C%20%5C%5C%20P%3D%280.15%29%5E5%20%3D0.0000759375)
So, the probability that all of them will be defective is 0.0000759375
On a right triangle, to find one missing side you can use this equation
a^2 + b^2 = c^2
a and b are the sides next to the right angle, and c is the hypotenuse (side not connected to right angle).
You first need to find the length of the dotted line before finding x. This is because to be able to use the above formula, you have to know the length of two out of three of the sides.
To solve the length of the dotted line, note that it also makes a triangle with the 5 unit line and the 5 √5 unit line. You can plug these numbers into the formula.
(5)^2+b^2=(5 √5)^2
25+b^2=125
b^2=100
b=10
Now that you know the length of the dotted line is 10 units, you can now solve for x
(20)^2+(10)^2=x^2
400+100=x^2
500=x^2
x= √500, which equals 22.361
