Answer 1

Answer:

  -30°

  or 330° or -150° or 210°

Step-by-step explanation:

The angle whose sine is 1/2 is 30°. Here, the sine is negative, indicating the angle is in the 3rd or 4th quadrants.

The angles in those quadrants with a reference angle of 30° are -30° or -150°. As positive angles, these are 330° or 210°, respectively.

Generally, the sin⁻¹ function (also called the arcsin function) is defined to have a range of -90° to +90°. Within that range, we can say ...

  sin⁻¹(-1/2) = -30°

_____

Additional comment

There are a few trig functions it is worthwhile to remember. These are shown in the attachment. The ordered pair points on the unit circle are (cos(θ), sin(θ)). If you remember the values of these in the first quadrant for 30°, 45°, and 60°, then you can work most of these "without a calculator" problems. (You also need to know how the signs change in the different quadrants.)

Answer 2

Answer:

210 degrees

Step-by-step explanation:

This is the 'arcsin' or 'inverse sine' function.  As written,

arcsin (-1/2) is requesting the angle (in degrees) whose sine is -1/2.

Note that because the sine function is defined as (opposite side)/hypotenuse, the following equation is true:

 -1            opposite

------  =  -------------------  =  sin x, where x is an angle in degrees.

  2         hypotenuse

If the sine is negative, that means that the angle x lies in either Quadrant III or Quadrant IV.  We see that the magnitude of the opposite side is HALF the magnitude of the hypotenuse.  

Cycling counterclockwise from the positive x axis, and continuing through Quadrant II into Quadrant III, we get a ray (hypotenuse) that is twice the length of the opposite side.  The angle of this ray as measured from the positive x-axis is 180 degrees plus 30 degrees, or  210 degrees.

You can check this by finding sin 210° on a calculator; the result is -1/2, which is what we were given up front.

A grocery store charges $4.50 per pound for organic apples. What is the cost c, in dollars, of p pounds of organic apples? Write an equation to represent the situation.

Answer:

c =4.50p

Step-by-step explanation:

If cost of apples in dollars = c

Weight of apples in pounds = p

The charge in dollar per pound of apple = $4.50

The total cost, c of apple can be expressed as :

Total cost, c = charge per pound * weigh of apple

Total cost, c = $4.50 * p

c = 4.50p

Answer:

Step-by-step explanation:

Kindly check the image below to see a visual of how the question is set up.

( my apologies for the terrible handwriting lol )

Now lets look back at the question.

The question is asking us to find the total length of Jayleen and Walter's entire walk.  

Essentially it's asking for the perimeter.

In order to find the perimeter we must find the length of the hypotenuse.

Notice that the image created forms a triangle with a right angle.

That being said we can use the Pythagorean Theorem to solve for the missing side length ( or the "shortcut" ) ( also note that the Pythagorean theorem only works with right triangles )

The Pythagorean theorem = [tex]a^2+b^2=c^2[/tex] where a and b = legs and c = hypotenuse

The two legs = 5 and 7 and the hypotenuse = the shortcut

That being said, we plug in the given values ( a and b ) and solve for "c"

[tex]5^2+7^2=c^2[/tex]

step 1: Simplify

[tex]5^2=25\\7^2=49\\25+49=74[/tex]

now we have 74 = c²

step 2 take the square root of each side

[tex]\sqrt{74} =8.60232\\\sqrt{c^2} =c[/tex]

we're left with c = 8.60232

This means that the shortcut that Jayleen and Walter took had a distance of 8.6

Finally we find the perimeter of the triangle

Perimeter = sum of side lengths

8.6 + 7 + 5 = 20.6

* round to the nearest whole number *

The answer would be 21

Answer:

[tex] \displaystyle \text C)\csc( {225}^{ \circ } )= - \sqrt{2} [/tex]

Step-by-step explanation:

we want to figure out the exact value of the following:

[tex] \displaystyle \csc( {225}^{ \circ} ) [/tex]

recall that,

[tex] \displaystyle \csc( \theta ) = \frac{1}{ \sin( \theta)} [/tex]

we are given [tex]\theta=225°[/tex]

substitute:

[tex] \displaystyle \csc( {225}^{ \circ } )= \frac{1}{ \sin( {225}^{ \circ} )} [/tex]

225° belongs to Q:III which we can clearly acquire from unit circle so,

[tex] \displaystyle \csc( {225}^{ \circ } )= \frac{1}{ \dfrac{ - \sqrt{2} }{2} } [/tex]

By simplifying complex fraction we get:

[tex] \displaystyle \csc( {225}^{ \circ } )= \frac{2}{ - \sqrt{ 2} } [/tex]

notice that, what we acquired isn't in the option so multiply it by √2/√2

[tex] \displaystyle \csc( {225}^{ \circ } )= \frac{2}{ - \sqrt{ 2} } \times \frac{ \sqrt{2} }{ \sqrt{2} } [/tex]

simplify multiplication:

[tex] \displaystyle \csc( {225}^{ \circ } )= \frac{2 \sqrt{2} }{ - \sqrt{ 4} } [/tex]

simplify square:

[tex] \displaystyle \csc( {225}^{ \circ } )= \frac{2 \sqrt{2} }{ - 2} [/tex]

reduce fraction:

[tex] \displaystyle \csc( {225}^{ \circ } )= - \sqrt{2} [/tex]

hence,

our answer is C

Enter a positive value for k that makes this statement true 20 times k is less than 20 but greater than o

Answers

Answer:

Step-by-step explanation:

If we're asked to use any positive value. It means we could have a wide variety of answer. A positive value of k that makes the equation 20k to be less than 20, yet greater than zero has to be any decimal value or a fraction, if you so wish.

As an example, if k is 0.5. Then we have

20k = 20 * 0.5 = 10, which is less than 20 and greater than zero

Again, if k is 0.9. Then we have

20k = 20 * 0.9 = 18, which is less than 20 and greater than zero.

So, you use any decimal number greater than 0, yet less than 1

Answer:

Range = 58

Mean = 25.81

Median = 17

Mode = 2, 9, 11, 12, 16, 17, 18, 41, 48, 50, 60

Upper Quartile = 11

Lower Quartile = 48

Step-by-step explanation:

Start by putting all of the values in order from least to greatest.

16, 18, 12, 9, 17, 2, 41, 48, 50, 60, 11

becomes

2, 9, 11, 12, 16, 17, 18, 41, 48, 50, 60

Range

The range is the difference between the highest and lowest value. So in this case, it's 58, because 60 - 2 = 58

Mean

The mean is another word for the average. To calculate the average, add all of the values and divide the sum by the number of values.

2 + 9 + 11 + 12 + 16 + 17 + 18 + 41 + 48 + 50 + 60 = 284

There are 11 values, so divide the sum (284) by 11:

284 / 11 = 25.8181818.

That rounds to 25.81

Median

The median is the middle value of the data set.

In 2, 9, 11, 12, 16, 17, 18, 41, 48, 50, 60 the middle value is 17. It has 5 values on each side of it.

Mode

The mode is the number that appears the most in the data set. Each value only appears once, so the mode is the entire list of numbers. 2, 9, 11, 12, 16, 17, 18, 41, 48, 50, 60

Upper Quartile

The upper quartile of a data set is the median of the numbers that are to the left of the median for the entire data set. The median is 17, so the numbers to the left are 2, 9, 11, 12, and 16. The median of those is 11 because it is in the middle. So the upper quartile is 11.

Lower Quartile

The lower quartile is found the same way the upper quartile is, but it's the median of the numbers to the right. The numbers to the right of 17 are

18, 41, 48, 50, and 60. The median of those is 48 because it's in the middle. So the lower quartile is 48.
