Answer:

Arcsin(X) is the inverse function of the Sin function.

This means that Arcsin(X) gives you the value Y that you need to input in the function of Sin in order to have Sin(Y) = X

Here you can see that we have Arcsin(2), this would be equal to a number that when you put it inside the sin function, you have

Sin(Y) = 2, but as you know, the range of the sin function is from -1 to 1, so you never can have Sin(Y) = 2, this is why this expression can not be simplified.

This is not possible because arcsin is the angle that will give you a sine value of 2. Sine values range from -1 to 1; there is no angle that will give you a sine of 2.

How many cups are in 3 pt? Please show work!!!!

ipn [44]

This is a simple application of english system conversions. I'm afraid that's all there is to it, you're just going to have to commit these to memory.

That said, I shall walk you through the problem. This one is fairly easy.

We know that in one pint there are two cups. As such, in two pints there are four cups, and in three pints there are six cups.

Therefore, there are 6 cups in 3 pints.

Hope this helps :)

Write an equation of the line that passes through the given point P and

dexar [7]

Answer (assuming it can be in point-slope form):

$y-4 = 3(x+2)$

Step-by-step explanation:

Use the point-slope formula $y-y_1 = m (x-x_1)$ , to write the equation of the line in point-slope form. Substitute x and y values for $m$ , $x_1$ , and $y_1$ in the formula.

Since $m$ represents the slope, substitute 3 for it. Since $x_1$ and $y_1$ represent the x and y values of a point the line intersects, take the x and y values of point P and substitute them into the equation as well. Substitute -2 for $x_1$ and 4 for $y_1$ . This gives the following answer:

$y-4 = 3(x+2)$

Determine whether each given pair of end points lies on the same horizontal or vertical line. If so, find the length of the line

inessss [21]

Answer:

a. In the same vertical line and segment lenght is 12 units.

b. Those are not in the same horizontal or vertical line.

c. In the same vertical line and segment lenght is 7 units.

d. In the same horizontal line and the segment lenght is 9 units.

Step-by-step explanation:

A. the end points are (0,-2) and (0,9). If we represent this two end points on a coordinate axis we can see that these points are in the same vertical line according to the y axis. And the lenght of the segment that joints the pair of points is 12 units lenght.

B. For subsection b the two given end points if we represent those on a coordinate axis we can say that thse two points are not in the same horizntal or verticall line each other. Because non of the numbers of each point match each other in the same axis.

C. The end points given are (3,-8) and (3,-1), and these points represented on a coordinate axis we can say that those are in the same vertical line. And the lenght of the segment each other is 7 units lenght.

D. The end points of subsection D are (-4,-4) and (5,-4) those points represented on a coordinate axis we can see that those are in the same horizontal line and the length of the segment is equal to 9 units.
