Que sucede al estudiar el comportamiento del coseno (en triangulos no rectangulos) de la misma forma que estudamos el seno?
Answer:
En contraste con el seno, el coseno permite diferenciar triángulos obtusángulos de triángulos acutángulos.
Step-by-step explanation:
Por Geometría Euclideana sabemos que la suma de todos los ángulos internos de un triángulo es igual a 180°, si el triángulo no es rectángulo, entonces acutángulo o obtusángulo.
Un triángulo es acutángulo cuando todos sus ángulos son agudos, es decir, cuyas medidas sean mayores que 0° y menores que 90°, mientras que un triángulo es obtusángulo cuando uno de sus ángulos es mayor que 90° y menor que 180° y los dos ángulos restantes son agudos.
El seno es una función periódica y acotada entre -1 y 1, que es positiva entre 0° y 180°, significando que esta función trigonométrica es demasiado "débil" para diferenciar a un triángulo obtusángulo de uno acutángulo. En cambio, el coseno es una función periódica y acotada entre -1 y 1, que es positiva entre 0° y 90°, y negativa entre 90° y 180°, convirtiéndola en un criterio "fuerte" para diferenciar triángulos obtusángulos de triángulos acutángulos.
Help please! The area of a swimming pool is 45 square meters. The width of the pool is 3 meters. What is the length of the pool in centimeters?
Answer: 15 m
Step-by-step explanation:
Given
The area of the swimming pool is [tex]A=45\ m^2[/tex]
Width of the pool is [tex]w=3\ m[/tex]
Suppose l is the length of the pool
So, the area is given by the multiplication of length and width
[tex]\Rightarrow A=lw\\\Rightarrow 45=3l\\\Rightarrow l=15\ m[/tex]
So, the length of the pool is 15 m.

Find the area of the shape 11cm 14cm 9cm 20cm who ever answers correctly gets brainlist
Answer:
Step-by-step explanation:
Given : shape 14cm 11cm 9cm 20cm
To Find : Find area
Solution:
20 - 1 1 = 9 cm
We can divide figure in 2 parts
rectangle = 14 cmx 11 cm
square = 9 cm x 9 cm
Area of rectangle = 14 * 11 = 154 cm²
Area of square = 9 * 9 = 81 cm²
Total area = 154 + 81
= 235 cm²

Answer:
Area = 235 square cm
Step-by-step explanation:
Given : shape 14cm 11cm 9cm 20cm
To Find : Find area
Split the figure into rectangle and square:
Rectangle : 14 x 11
Square : 9 x 9
[tex]Area \ of \ rectangle : 14 \times 11 = 154 \ cm^2[/tex]
[tex]Area \ of \ square = 9 \times 9 = 81 \ cm^2[/tex]
[tex]Total \ area = 154 + 81 = 235 \ cm^2[/tex]
The width of classroom is 4 meters less than the length, and the area is 192m^2. If the length is x m, find an equation in x and hence, find the dimensions of the classroom
Step-by-step explanation:
x(x-4) = 192
the Equation:
x²-4x -192 =0
=> (x-16) (x+12) =0
x= 16 or x= -12
since the x should be a possitive, so x = 16
the dimension :
the length = 16 m
the width = 12 m
There are 5 red marbles, 15 blue marbles, and 5 green marbles in a bag. You reach in and randomly draw a marble, replace it, and draw another marble. What is the probability that one will be red and one will be blue?
Answer:
Blue: 3/5
Red: 1/5
if the question is asking for the probability of if one marble you will pick out of bag is red OR blue, it will be 4/5
Step-by-step explanation:
add all the marbles together. 25 marbles.
so if there are 15 blue marbles, then there would be a 15 out of 25 chance you will get a blue marble. simplified is 3/5. same goes for the red marbles.

Mauritius island is 2 km due south of its closest point along a straight coastline. Gibril is staying at a private room on the shore that is 6 km east of that point. Gibril is planning to go from the room to the island. Suppose Gibril runs at a rate of 8 kmph and swims at a rate of 3 kmph. How far should Gibril run before swimming to minimize the time it takes to reach the island?
Answer:
5.19 Km
Step-by-step explanation:
According To the Question,
Suppose he Runs Xkm before swimming to minimize the time it takes to reach the island .
So, he should swim [tex]\sqrt{2^{2}+(6-X)^{2} } Km[/tex] .
Now The Total Time is t = [tex]\frac{X}{8} + \frac{\sqrt{2^{2}+(6-X)^{2} } }{3}[/tex] .
t = [tex]\frac{X}{8} + \frac{\sqrt{X^{2}-12X+40 } }{3}[/tex]
[tex]\frac{dt}{dX}=1/8 + 1/3 * 1/2 * \frac{2X-12}{\sqrt{X^{2}-12X+40 } }[/tex]
[tex]\frac{dt}{dX}=1/8 + \frac{1}{3} * \frac{X-6}{\sqrt{X^{2}-12X+40 } }[/tex]
Now Put [tex]\frac{dt}{dX} = 0[/tex] , we get
[tex]1/8 + \frac{1}{3} * \frac{X-6}{\sqrt{X^{2}-12X+40 } } = 0[/tex]
[tex]\frac{1}{3} * \frac{X-6}{\sqrt{X^{2}-12X+40 } } = - \frac{1}{8}[/tex]
8(X-6)= -3 × [tex]{\sqrt{X^{2}-12X+40 }[/tex]
square on both side,We get
64(X²-12X+36) = 9X² - 108X +360
55X² -660X + 1944 = 0
Apply Shri Dharacharya formula, To Find The Value of 'X'
X =[ - (-660) ±[tex]\sqrt{(-660)^{2}-4*55*1944 }[/tex] ] ÷ 2×55
X = (660±√7920) / 110
X= (660 - 89 ) / 110 ⇒ (Neglect '+' because it give 749/110 = 6.8 km Which is not possible )
X=571/110 ⇔ 5.19km he Should Run before swimming to minimize the time .

The 8th term of the sequence is 255
Step-by-step explanation:
To find the 8th term of the sequence, we have to use the given sequence formula
All we have to do here is to make a substitution
We simply have to substitute the value 8 for n as follows;
a8 = 2^8 - 1
a8 =256-1
a8 = 255

A total of 573 tickets were sold for the school play. They were either adult tickets or student tickets. There were 73 more student tickets sold than adult tickets. How many adult tickets were sold?
Answer:
146 adult tickets were sold
Step-by-step explanation:
subtract 73 from 573 which = 500
then you'll take away 500 from 73 =427
then you will subtract 427 from 573= 146

Answer:
the first one
Step-by-step explanation:
it is really easy to see in this case.
the main formula is just a sum of a sum.
anything you just add you can split in its parts and then sum it all up - it is still the same.
so, the sum of (n + 3/n) can be split without any additional tricks into the sum of n and the sum of 3/n, and then add both results together.
the second option is wrong, because a division cannot be split like an addition. just try the first two elements (n=10 and n=11) for the simplified formula of the sum of (3/n). 3/10 + 3/11 is definitely not the same as (3 + 3) / (10 + 11).
the third and fourth option are already disqualified, because "n" assists outside of the sum operation (but "n" is only defined inside of it).

Check 2. The circumference of a circle is C centimeters. The diameter of the circle is 6 centimeters. Write an expression that represents the value of n.
Answer:
radius of circle = 3cm
circumference = 18.84cm
diameter = 6cm
Step-by-step explanation:
if the diameter of circle is 6cm
radius of circle = diameter/2
= 6/2
= 3
circumference of circle = 2[tex]\pi[/tex]r
= 2 x 3.14 x 3
= 6.28 x 3
= 18.84

Answer:
30000 : 20000
Step-by-step explanation:
Given the ratio
[tex]\frac{1}{10}[/tex] : [tex]\frac{1}{15}[/tex] ( multiply both parts by 30 the LCM of 10 and 15, to clear the fractions )
= 3 : 2
sum the parts of the ratio, 3 + 2 = 5 parts
Divide the amount by 5 to find the value of 1 part of the ratio
50000 ÷ 5 = 10000 ← value of 1 part of the ratio, then
3 parts = 3 × 10000 = 30000
2 parts = 2 × 10000 = 20000
Then
50000 = 30000 : 20000 in the ratio 3 : 2
