Answer:

(-2,0)

Step-by-step explanation:

Herr you go, I hope this helps you.

The coordinates of the vector after rotation is (-2,0)

The given parameters are:

Vector = (0,2)

Rotation = 270°clockwise about the origin

The rule of 270° rotation clockwise about the origin is:

(x,y) = (-y,-x)

So, we have:

(0,2) = (-2,0)

Hence, the coordinates of the vector after rotation is (-2,0)

Answer: 150.02 m

Step-by-step explanation:

Given

The height of building A is 125 m

the angle of elevation to the top of building B is [tex]18^{\circ}36'[/tex]

and the angle of depression of the base of Building B is [tex]39^{\circ}48'[/tex]

Suppose the width of the street is x

from the figure, we can write

[tex]\Rightarrow \tan (39^{\circ}48')=\dfrac{125}{x}\\\\\Rightarrow \tan (39.8^{\circ})=\dfrac{125}{x}\\\\\Rightarrow x=\dfrac{125}{\tan 39.8^{\circ}}\\\\\Rightarrow x=150.02\ m[/tex]

Thus, the width of the street is [tex]150.02\ m[/tex]

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,

Answer:

w = 1.28.

Step-by-step explanation:

To find 'w', simply divide the answer by the coefficient.

[tex]3.84/3=1.28[/tex]

[tex]w=1.28[/tex]

REMEMBER: ANYTIME YOU SEE A COEFFICIENT AND A VARIABLE, YOU MUST MULTIPLY THE COEFFICIENT AND THE VARIABLE.

We can check our answer by multiplying.

[tex]3*1.28 = 3.84[/tex].

Therefore, w = 1.28.

Answer:

Answer:

21

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:

She shaded area?

12 x 10 = 120

6 x 7 = 42

42 divided by 2 = 21

Now we subtract both areas:

120 - 21 = 99 of the shaded region.

Answer:

99

Step-by-step explanation:

7 * 6 is 42 then divide by 2 = 21

12 * 10 is 120

120 - 21 = 99

Answer:

The answer for Acellus people is  9.8

Step-by-step explanation:

The missing side of Right triangle will be [tex]9.8[/tex].

Right triangle is a triangle in which one angle is of [tex]90^0[/tex].

We have,

Hypotenuse [tex]=18[/tex] cm

Perpendicular [tex]=x[/tex] cm

One of the angle [tex]=33^0[/tex]

So,

Using the Trigonometric angles,

[tex]Sin33^0=\frac{Perpendicular}{Hypotenuse}[/tex]

So,

[tex]Sin33^0=\frac{x}{18}[/tex]

⇒

[tex]x=18*Sin\ 33^0[/tex]

So,

[tex]x=9.8[/tex]

The missing side is [tex]9.8[/tex] .

Hence, we can say that the missing side of Right triangle will be [tex]9.8[/tex].

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.

Answer:

C. 69 (nice)

Step-by-step explanation:

Sine: Opposite side over hypotenuse

Cosine: Adjacent side over hypotenuse

Tangent: Opposite side over adjacent side

Respective to angle O, we are given the adjacent side, 5, and the hypotenuse 14, so we can use cosine.

cos(O)=5/14

O=arcsin(5/14)≈69.0752

Complete question :

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
