Using trigonometric relations, we will see that:
sin(θ ) = -0.8
How to get the sine of the angle?
For any point (x, y), the angle between the positive x-axis and the ray that connects the origin with the point (x, y) is:
θ = Atan(y/x)
In this case, the point is (3, -4), then the angle is:
θ = Atan(-4/3) = -53.13°
Then the sine of theta is:
sin(θ = -53.13°) = -0.8

la suma de dos ángulos internos es siempre mayor que la medida del tercer ángulo
verdadero o falso y por que
Utilizando el triangulo rectangulo como contraejemplo, veremos que esto es falso.
¿Es la propicición verdadera o falsa?Primero, sabemos que para todo triangulo la suma de sus angulos internos es igual que 180°.
Ahora, vamos a el triangulo más comun. El triangulo rectangulo.
Este es el triangulo que tiene uno de sus angulos internos igual a 90°.
Digamos que los otros dos angulos internos son A y B, entonces tendriamos:
A + B + 90° = 180°
Despejando A + B obtenemos:
A + B = 180° - 90° = 90°
A + B = 90°
Entonces vemos que la suma de estos dos angulos internos es igual que el tercer angulo.
Encontramos un contraejemplo de la proposición, asi, concluimos que la proposición es falsa.

Create diagrams to represent the possible cases for common tangents between two circles. Your diagram can be created using multimedia sources or drawn by hand. They should not be copied and pasted from a website. Explain why your diagrams satisfy the given criteria.
No Common Tangents (10 points)
Diagram:
Justification:
The diagram to represent the possible cases for common tangents between two circles is as shown in the attachment.
How to Create Common Tangents?
A tangent line to a circle is defined as a line that touches the circle at exactly one point, never entering the circle's interior.
1. When one circle is in between another and one circle does not touch the other one, then tangent is not possible.2. When one circle is in between another and one circle touches the other one at a point inside the circle, then only one tangent is possible.3. When one circle intersects the other one, then two tangents are possible.4. When one circle touches the other one at a point outside, then three tangents are possible.5. When one circle neither intersects the other one nor inside the other one, then four tangents are possible.Thus, the diagram to represent the possible cases for common tangents between two circles are as attached below.

Identify the line with an undefined slope
Answer:
d. vertical line
Step-by-step explanation:
A line with an undefined slope is a vertical line
Slope is the change in y over the change in x
When the slope is undefined, it means that the x does not change, which is a vertical line
Answer:
Line D
Step-by-step explanation:
Slope is defined as rise/run. Since a vertical line has zero run and infinite rise the equation is infinity/0 and anything divided by zero is undefined.

Please Answer Asap!!! Write the equation based on the graph of the following base 2 logarithmic function:
The graph of the logarithmic function that passes through (-2,-2) and (1,0) is [tex]\log_2(x+3)-2[/tex].
Suppose that the function is
[tex]f(x)=\log_2(x+c)+d[/tex]
Then there are two observations that we must consider from the figure
The graph must pass through (-2,-2) and (1,0)So,
[tex]-2=\log_2(-2+c)+d[/tex]
[tex]\implies -2+c=e^{-2-d} ...~...~(1)[/tex]
And,
[tex]0=\log_2(1+c)+d\\\implies 1+c=e^{-d} ~...~...~(2)[/tex]
Observe the figure given below we see that the graph of
[tex]\log_2(x)[/tex] passes through (1,0) but does not pass through (-2,-2) and the graph is to the right of (-2,-2) hence, we need the graph to move left.
When we increase c the graph [tex]\log_2(x+c)+d[/tex] moves left and
When we decrease d then the graph [tex]\log_2(x+c)+d[/tex] moves down.
That makes the graph required to be [tex]\log_2(x+3)-2[/tex].
Hence, the graph of the logarithmic function that passes through (-2,-2) and (1,0) is [tex]\log_2(x+3)-2[/tex].

Find a 95% confidence interval for the mean amount of time spent on this ride. Round the values in your confidence interval to two decimal places. The 95% percent confidence interval is
95% confidence interval is 1.96
A confidence interval is defined as the range of values that we observe in our sample and for which we expect to find the value that accurately reflects the population.
For 95% confidence interval, we will keep 95% area in the center and will divide the remaining area equally on both sides.
From Standard Normal table, P(-1.96 < Z < 1.96) = 0.95, i.e., there is a 95% probability that a standard normal variable, Z, will fall between -1.96 and 1.96.
Hence 95% percent confidence interval is 1.96

if a football player passes a football 4 feet off the ground with the velocity of 36 feet per second, how long will it take the football to hit the ground? Use the equation h=-16t^2+36t+4
The ball will hit the ground after 2.355 secs
Velocity of an objectThe velocity of an object the change of displacement with respect to time.
Given the function that represents the height of football ground
h(t) = -16t^2+36t+4
The ball will hit the ground at the point where the height h(t) = 0
Substitute
-16t^2+36t+4 = 0
16t^2-36t-4 =0
4t^2-9t-1= 0
Factorize
t = 9/8 + √97/8
t = 9/8 + 1.23
t = 2.355secs
Hence the ball will hit the ground after 2.355 secs

Step-by-step explanation:
The Law of large numbers.
What is the Law of natural numbers?The law of large numbers plays the main role in probability and statistics. It means that if you repeat an experiment independently so many times and average the result, what you get has to be close to the expected value.
An example of the Law of Large Numbers:
Let's assume that you rolled the dice three times and the outcomes were 6, 6, and 3. Then the average result is 5.
So, according to the law of the large numbers, if we roll the dice a large no. of times, then the average result should be closer to the expected value.
It also states that probability and statistics set a sample size that grows, and the mean of the sample size gets closer to the average of the entire population.
