Answer:

D) Domain: (-∞, ∞)

Range: (-∞, ∞)

Step-by-step explanation:

The domain is the input values, or the x values.

We can put in any x values for this function.

Domain : (-∞, ∞)

The range is the output values or the y values.

We can get any output values for this function

Range: (-∞, ∞)

If y is a positive integer, for how many different values of y is RootIndex 3 StartRoot StartFraction 144 Over y EndFraction End
Lelechka [254]

The value of y will be 18 or 144.

Given information:

The given expression is \sqrt[3]{\frac{144}{y} }.

It is required to find the values of y which are whole numbers.

Now, factorize 144 as,

144=2\times2\times2\times2\times3\times3\\144=2^3\times2\times3\times3

So, for the value of given expression to be a whole number, the value of y should be,

2\times3\times3=18 or 144.

For the above values of y, the given expression will be,

\sqrt[3]{\frac{144}{y} }=\sqrt[3]{\frac{144}{18} }\\=\sqrt[3]{8} =2\\\sqrt[3]{\frac{144}{y} }=\sqrt[3]{\frac{144}{144} }\\=\sqrt[3]{1} \\=1

Therefore, the value of y will be 18 or 144.

Pete can type 80 words in the same time that Ralph can type 50 words. If they type at those rates
tamaranim1 [39]

Answer:

After the extended period of time, Pete would have typed 6400  words.

Step-by-step explanation:

Given the data in the question;

In the same time;

number typed word of Pete = 80

type word of Ralph = 50

After a period time;

number of typed word of Pete = ?

number of typed word of Ralph = 4000

so, let x represent the number of typed word by Pete after an extended period.

so

80 words = 50 words

x words =    4000 words

we cross multiply

x × 50 = 4000 × 80

x = ( 4000 × 80 ) / 50

x = 320000 / 80

x = 6400

Therefore, After the extended period of time, Pete would have typed 6400  words.

The table can be used to determine the solution of equations, 2x − 2y = 6 and 4x + 4y = 28.
natta225 [31]

we have

2x-2y=6 ------> equation 1

4x+4y=28 ------> equation 2

Multiply by 2 the equation 1

4x-4y=12 ------> equation 3

Sum equation 2 and equation 3

4x+4y=28\\ 4x-4y=12\\ ------\\ 8x=40\\ x=40/8\\ x=5

Substitute the value of x in the equation 2

4x+4y=28

4*5+4y=28\\ 4y=28-20\\ 4y=8\\ y=8/4\\y=2

therefore

the answer is the option B

Gavyn and Alex win some money and share it in the ratio 4:1. Gavyn gets £18 more than Alex. How much did they get altogether?
densk [106]

Answer:

£30

Step-by-step explanation:

Gavyn has £18 more than Alex

—› G - A = £18

—› 4u - 1u = 3u = £18

1u = £18 ÷ 3

= £6

total units = 4 + 1 = 5

5u = 5 × £6 = £30

P varies directly with the square of R. When R is 4, P is 56. Find the value of P when R is 6
Sav [38]
Hey!
The formula of direct variation is y = kx. So we know that p = kr^2
Hint: after it says varies, it's basically the equal sign. 
so we can set it up
56 = 4^2k
56=16k
now we want k alone so we have to divide 16 on both sides
k=3.5
We can now solve for p like it asks
p = 3.5*6^2
p=126
There's your answer!
Hope this helps!
