2/6

10/15

8/15

1/3

Answer:

Newtons

Step-by-step explanation:

Joules measure electrical power and celcius and Kelvin measures temperature.

Answer:

1 would be 1320

3 would be 3960

4 would be 5280

Step-by-step explanation:

The cost of 1, 3 and 4 ounces of gold in 2016 was $1,320, $3,960 and $5,280 respectively.

Cost of 2 ounces of gold in 2016 = $2,640

Cost of 1 ounce of gold in 2016 = Cost of 2 ounces of gold in 2016 ÷ 2

= $2,640 ÷ 2

= $1,320

Cost of 3 ounces of gold in 2016 = Cost of 1 ounce of gold in 2016 × 3

= $1,320 × 3

= $3,960

Cost of 4 ounces of gold in 2016 = Cost of 1 ounce of gold in 2016 × 4

= $1320 × 4

= $5,280

Therefore, the cost of 1, 3 and 4 ounces of gold in 2016 are $1,320, $3,960 and $5,280 respectively.

Answer:

(f o g) = -5x+22

Step-by-step explanation:

f o g  basically means f(g(x))

So:

f(g(x)) = -5(x-4)+2

f(g(x)) = -5x+20+2

f(g(x)) = -5x+22

Therefore: (f o g) = -5x+22

This is called function composition. Basically, the output of g(x) goes into the input of f(x).

Answer:

sin2x = [tex]\frac{30}{34}[/tex]

Step-by-step explanation:

Given

tanx = [tex]\frac{3}{5}[/tex] = [tex]\frac{opposite}{adjacent}[/tex]

This is a right triangle with legs 3 and 5

Let the hypotenuse be h , then using Pythagoras' identity

h² = 3² + 5² = 9 + 25 = 34 ( take the square root of both sides )

h = [tex]\sqrt{34}[/tex]

Thus

sinx = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{3}{\sqrt{34} }[/tex]

cosx = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{5}{\sqrt{34} }[/tex]

Hence

sin2x = 2sinxcosx = 2 × [tex]\frac{3}{\sqrt{34} }[/tex] × [tex]\frac{5}{\sqrt{34} }[/tex] = [tex]\frac{2(3)(5)}{\sqrt{34}(\sqrt{34}) }[/tex] = [tex]\frac{30}{34}[/tex]

Answer:

-2.9375

Step-by-step explanation:

2x-14x+47=0

16x+47=0

16x=-47

x=-2.9375

Answer:

x=7+√ 2 or x=7-√ 2

Step-by-step explanation:

x^2-14x+47=0

Completing the square,

x^2-14x+49-2=0

x^2-14x+49=2

x^2-7x-7x+49=2

x(x-7)-7(x-7)=2

(x-7)^2=2

x-7=√ 2 or x-7=-√ 2

x=7+√ 2 or x=7-√ 2

[tex]f(x) = y = x - \frac{5}{6} \\ [/tex]

Subtract the sides of the equation plus 5/6

[tex]y + \frac{5}{6} = x \\ [/tex]

So ;

[tex] {f}^{ - 1}(x) = x + \frac{5}{6} \\ [/tex]

Answer:

A.

Step-by-step explanation:

Plugging in all the values into the equation, only A holds a true statement.

Answer:

Let's see what to do buddy...

Step-by-step explanation:

_________________________________

Step (1)

First we need two points of the table :

I choose a = ( 0 , 3 ) and b = ( 2 , 0 ) .

_________________________________

Step (2)

To find the slope of linear functions using two points, we use the following equation :

[tex]slope = \frac{y(b) - y(a)}{x(b) - x(a)} \\ [/tex]

Where a and b are two points of the function.

_________________________________

Step (3)

Now just need to put the coordinates of the points which we chose.

a = ( 0 , 3 ) °•°•°•°•°•°•° b = ( 2 , 0 )

[tex]slope = \frac{0 - 3}{2 - 0} \\ [/tex]

[tex]slope = - \frac{3}{2} \\ [/tex]

Answer:

Additional bags required = 4

Step-by-step explanation:

Marianne buys number of bags of potting soil = 16

Each bag weighs = [tex]\frac{3}{4}[/tex] pounds

Total weight of 16 soil bags = [tex]16\times \frac{3}{4}=12[/tex] pounds

If Marianne's father requires potting soil = 15 pounds

Amount of additional soil he will require = 15 - 12

                                                                   = 3 pounds

Therefore, number of additional soil bags required = [tex]\frac{\text{Weight of soil required}}{\text{Soil in each bag}}[/tex]

                                                                                     = [tex]\frac{3}{\frac{3}{4}}[/tex]

                                                                                     = [tex]3\times \frac{4}{3}[/tex]

                                                                                     = 4 bags

Additional bags required by Marianne= 4

50 magazines

because ratio is division and 225/5 is 25 and you multiply the 2 by 25 and you get 50

There are 64 magazines in the library.

A ratio indicates how many times one number contain in another number. The ratio of two number is written as x : y, which is equivalent to x/y. Where, x and y are individual amount of two quantities. And, Total quantity gives after combine as x + y.

We have to given that;

The ratio of books to magazines in the children's section at the library is 5: 2.

Let number of books = 5x

And, Number of magazines = 2x

Here, There are 225 books in the library.

Hence, We can formulate;

⇒ 5x + 2x = 225

⇒ 7x = 225

⇒ x = 32

Hence, Number of magazines = 2x

                                               = 2 × 32

                                               = 64

B = 61°

C = 61°

Step-by-step explanation:

The sum of all the angles is 360.

When the angles are formed with straight lines like shown the angles back to back are equivalent or equal.

So you can take 119 and add it by itself to get 238.

You then get 360 and subtract 238 which gets you 122.

Then divide 122 by two and you have the answer for both b and c which is 61.

Answer:

First, remember the relation:

Distance = Speed*Time.

We know that the distance is 120mi.

A) For the biker we know that:

Time  = 8hours.

Speed = Distance/Time = 120mi/8h = 15 mi/h.

B) For the bus we know that:

Time = 2 hours.

Speed = Distance/Time = 120mi/2h = 60 mi/h.

C) For the truck we know that:

Time = 2.5 hours.

Speed = Distance/Time = 120mi/2.5h = 48 mi/h.

D) For the rider on a horse we know that:

Time = 18.75 hours.

Speed = Distance/Time = 120mi/18.75h = 6.4 mi/h.

E) The equation for the speed is:

Speed = Distance/Time.

You can see that time is in the denominator, this means that if for a fixed distance, the time increases, then the denominator increases, which would imply that the speed decreases.

Then the speed is inversely proportional to the time when the distance is fixed.

Answer:

C. The Function is positive when x<0 and when x>0.
