Step-by-step explanation:

sin(2∅)-sin(6∅)

Sum product Identity

sinα  - sinβ  = 2cos((α+β)/2)sin((α-β)/2)

Putting α= 2∅ and β= 6∅ in the identity we get

sin(2∅)-sin(6∅) = 2cos((2∅+6∅)/2)sin((2∅-6∅)/2)

                        =2cos(8∅/2)sin(-4∅/2)

                        =2cos(4∅)sin(-2∅)

Step-by-step explanation:

He cycles [tex]\frac{3}{4}[/tex] Km and jogs [tex]\frac{3}{4}[/tex] - [tex]\frac{1}{6}[/tex]

Adding the 2 together gives the total he cycled/ jogged

[tex]\frac{3}{4}[/tex] + [tex]\frac{3}{4}[/tex] - [tex]\frac{1}{6}[/tex]

We require the denominators to be common before adding/ subtracting

The lowest common denominator of 4 and 6 is 12, hence

= [tex]\frac{9}{12}[/tex] + [tex]\frac{9}{12}[/tex] - [tex]\frac{2}{12}[/tex]

= [tex]\frac{9+9-2}{12}[/tex]

= [tex]\frac{16}{12}[/tex] = [tex]\frac{4}{3}[/tex] = 1 [tex]\frac{1}{3}[/tex] Km

Do 3/4 x 3 = 9/12

Do 1/6 x 2 = 2/12

Then do 9/12 - 2/12 = 7/12

Next you do 7/12 + 9/12 = 16/12

Then simplify. 1 4/12

Simplify again. 1 1/3

It’s the forth one

The answer is -|x-4|.

Answer:y=-|x-4|

Step-by-step explanation:

we know the graph of y=|x| touches at x=0 and opens upward towards y axis

but this graph is facing downwards therefore it should be of form

y=-|x|

but it touches the x axis at x=4

therefore the graph is represented by

y=-|x-4|

4 is added inside the mod because it intersect x axis at x=4

The graph would be y=-|x-4|+1 if it shifts 1 unit upwards.

Whenever you have a decision tree like this, the probability of reaching a specific leaf is the multiplication of the probabilities of each step you have to reach the leaf.

So, in order to reach the "hardcover and nonfiction" leaf, we have to take the "buys hardcover" branch (probability 0.35), and then the "buys nonfiction" branch (probability 0.55).

Given what we said above, the probability for "hardcover and nonfiction" is

[tex]0.35\cdot 0.55=0.1925[/tex]

The probability of buying a hardcover and non-fiction book is 0.1925

We have the below parameters for our Calculation;

The probability that someone buys a hardcover and non- fiction book ;

Step-by-step explanation:

Because her answer is greater than 2 (7/3 = 2 1/3)

We are multiplying a number less than 2 (1 2/3) by a number less than 1 (5/6), so we have less than one of the number 1 2/3, which has to be less than 1 2/3.

Step-by-step explanation:

Final answer:

To subtract 6 ounces from 3 pounds, convert 3 pounds to ounces (3 x 16 = 48 ounces), subtract 6 ounces (48 - 6 = 42 ounces), then convert back to pounds and ounces (42 ounces = 2 pounds and 10 ounces). The answer is 2 pounds, 10 ounces.

Explanation:

Subtracting Ounces from Pounds

The question asks to subtract 6 ounces from 3 pounds. In order to compare or subtract different units of weight, it is essential to convert them to the same unit. Firstly, we must remember the unit equivalence where 1 pound = 16 ounces. Now, to start the conversion, we multiply the number of pounds by 16 to get the total number of ounces, which is a step in solving these types of conversion problems.

Therefore, for 3 pounds:

3 pounds × 16 ounces/pound = 48 ounces.

Now subtract the given ounces: 48 ounces - 6 ounces = 42 ounces.

Since we know there are 16 ounces in a pound, we divide the total ounces by 16 to convert back to pounds and ounces.
42 ounces ÷ 16 ounces/pound = 2 pounds with a remainder of 10 ounces.

Hence, subtracting 6 ounces from 3 pounds gives us 2 pounds, 10 ounces.

Answer:

Option A. [tex]SQ=7\ cm[/tex]

Step-by-step explanation:

we know that

In the figure

The triangles PTQ and RTS are similar by AA Similarity Theorem

so

Remember that

If two figure are similar, then the ratio of its corresponding sides is equal

so

[tex]\frac{PT}{RT}=\frac{QT}{ST}[/tex]

we have

[tex]RT=RP+PT=6+18=24\ cm[/tex]

[tex]QT=21\ cm[/tex]

[tex]SQ=ST-21\ cm[/tex] ------> equation A

substitute the values and solve for ST

[tex]\frac{18}{24}=\frac{21}{ST}[/tex]

[tex]ST=21*24/18[/tex]

[tex]ST=28\ cm[/tex]

The difference between fixed expenses and variable expenses is that fixed expenses do not change, regardless of how many items are produced. Variable expenses change based on the number of items produced.

An example of a fixed expense is the rent. The rent is always the same amount, regardless of production.

Materials would be a variable expense. You need enough material to make each item, so the more items you produce, the more material you need.

Answer:

csc θ = [tex]\sqrt{85}[/tex]/6

sec θ = [tex]\sqrt{85}[/tex]/7

tan θ = 6/7

Step-by-step explanation:

The first thing to do will be to compute the length of the hypotenuse using the Pythagoras theorem;

6^2 +7^2 = hypotenuse^2

hypotenuse = [tex]\sqrt{85}[/tex]

csc θ = 1/sinθ

sinθ = opposite side/hypotenuse

       = 6/[tex]\sqrt{85}[/tex]

csc θ = [tex]\sqrt{85}[/tex]/6

sec θ = 1/cosθ

cosθ = adjacent side/hypotenuse

sec θ = hypotenuse/adjacent side

         = [tex]\sqrt{85}[/tex]/7

tan θ = Opposite side/adjacent side

         = 6/7

The lengths of the legs of each triangle are:

1) Leg = √19

2) Leg = √105

3) Leg = √60

How to use Pythagoras Theorem?

Pythagoras Theorem is defined as the way in which you can find the missing length of a right angled triangle.

The triangle has three sides, the hypotenuse (which is always the longest), Opposite (which doesn't touch the hypotenuse) and the adjacent (which is between the opposite and the hypotenuse).

Pythagoras is in the form of;

a² + b² = c²

a = √(c² - b²)

1) We are given that:

Hypotenuse = 10

Opposite side = 9

Thus, using Pythagoras Theorem, we have:

Leg = √(10²- 9²)

Leg = √19

2) We are given that:

Hypotenuse = 19

Opposite side = 16

Thus, using Pythagoras Theorem, we have:

Leg = √(19²- 16²)

Leg = √105

3) We are given that:

Hypotenuse = 8

Opposite side = 2

Using Pythagoras Theorem, we have:

Leg = √(8²- 2²)

Leg = √60

Answer:

P(x) = x³ - 3x² - 5x + 15

Step-by-step explanation:

∵ The roots of the polynomial are -√5 , √5 , 3

∴ The polynomial has 3 factors:

  (x - √5) , (x + √5) , (x - 3)

∴ P(x) = (x - √5)(x + √5)(x - 3)

          = (x² + √5x - √5x - 5)(x - 3)

          = (x² - 5)(x - 3) = x³ - 3x² - 5x + 15

∴ P(x) = x³ - 3x² - 5x + 15

Final answer:

To find out how many cups of orange juice Harry should use with 18 cups of soda water, set up a proportion and solve for x.

Explanation:

In this problem, we know that Harry uses 2 parts orange juice to 2 parts soda water for his fruit punch. This means that for every 2 cups of orange juice, he uses 2 cups of soda water. Since the amount of soda water is directly proportional to the amount of orange juice, we can set up a proportion to find out how many cups of orange juice Harry should use with 18 cups of soda water.

2 cups orange juice / 2 cups soda water = x cups orange juice / 18 cups soda water

To solve the proportion, we can cross multiply:

2 cups orange juice * 18 cups soda water = x cups orange juice * 2 cups soda water

36 cups orange juice = 2x cups soda water

By dividing both sides of the equation by 2, we find that Harry should use 18 cups of orange juice with 18 cups of soda water.

Answer:

B.  The relationship between the variables in the table is quadratic because the second differences are constant.

Step-by-step explanation:

We have to look for the differences in the y values of the given table.

The y values are:

0, 2, 6, 12, 20, 30, 42

The differences between the consecutive values are:

2, 4, 6, 8, 10, 12

These are the first differences and are not constant. This means the relationship is not linear. Now we again find the differences between the consecutive values:

2, 2, 2, 2, 2

These are the second differences. The second differences are constant. So this means the given relationship is quadratic.

Therefore, option B gives the correct answer. The relationship between the variables in the table is quadratic because the second differences are constant.

Answer:

STEP ONE: 2x

STEP TWO: 5=X (should be the final answer)

Step-by-step explanation:

Hi Lasagna!

So basically, this is extremely simple. In order to "solve" that equation, the x has to be on one side. The easiest way to do this would be to take the 2x to the other side. If you want the 2x to go to the other side, you need to subtract it (since it is already positive, therefore it needs to cancel out). Once you do that, you must always do the same thing to the other side: subtract 2x from 3x. That should get you one x there, which you can just write as x if it's just one. Then you're all set! :D

Answer: step 1. 2 from both sides

Step-by-step explanation:

just take away the = number by doing the opposite action for ex. if it it 2x then divide both sides by 2.

Answer:

6x < 16 ( divide both sides by 6 )

x < [tex]\frac{16}{6}[/tex], that is

x < [tex]\frac{8}{3}[/tex]
