A puppy weighs 9 newtons on Earth and about 2 newtons on the planet Namar. A girl weighs 400 newtons on Earth. About how many ne
serious [3.7K]

Hi there!

In order to answer your question, you'll need to use the cross product method (let's say that Newtons = N):

9N on Earth = 2N on Namar

400N on Earth = xN on Namar

(2 × 400) ÷ 9 = xN on Namar

800 ÷ 9 = xN on Namar

88.888.. = xN on Namar


Since your answer must be to the nearest Newton, I'm guessing that you need to round your answer to the nearest whole number. This means that since the number in the tenths column is more than 5 (could also be equal to 5), you need to round the number up.


88.888... rounded to the nearest whole number = 89


Your answer is: The girl weigh 89 newtons on Namar.


There you go! I really hope this helped, if there's anything just let me know! :)

I need help urgent plz someone help me solved this problem! Can someone plz help I’m giving you 10 points! I need help plz help
Hitman42 [59]

Answer: L = 20.25

<u>Step-by-step explanation:</u>

T=2\pi \sqrt{\dfrac{L}{32}}

Given: T = 5, π = 22/7

5=2\bigg(\dfrac{22}{7}\bigg)\sqrt{\dfrac{L}{32}}\\\\\\\dfrac{5}{2}\bigg(\dfrac{7}{22}\bigg)=\sqrt{\dfrac{L}{32}}\\\\\\\dfrac{35}{44}=\sqrt{\dfrac{L}{32}}\\\\\\\bigg(\dfrac{35}{44}\bigg)^2=\bigg(\sqrt{\dfrac{L}{32}}\bigg)^2\\\\\\\bigg(\dfrac{35}{44}\bigg)^2=\dfrac{L}{32}\\\\\\32\bigg(\dfrac{35}{44}\bigg)^2=L\\\\\\\large\boxed{20.25=L}

Given no other restrictions, what are the domain and range of the following function?
balandron [24]

Domain is: D = all real numbers

and Range is: R = {y | y > 0}

Option C is correct.

Step-by-step explanation:

We are given a function f(x) = x^2 - 2x + 1 and we need to find domain and range of this function

Domain:

The domain of  a function is the set of points for which the function is real and defined.

Since all the values give the result which is real and defined so domain is all real numbers.

Range:

The set of values of the variable that is dependent, the function should be defined.

So, all the values should be greater than 0 i.e {y | y > 0}

So, Domain is: D = all real numbers

and Range is: R = {y | y > 0}

Option C is correct.

Keywords: Domain and Range
