49 kms : 7 tanks

Hello there,
Distance : Tanks
49           :   7
Since both sides are divisible by 7, 

Distance : Tanks
7             :    1

On side note: From what I have learnt, do not put any units (in this case km) when solving ratio

Hope this helps

Would you need to use the chain rule to find the derivative of this function?
Nutka1998 [239]

Answer:

TRUE. We need to use the chain rule to find the derivative of the given function.

Step-by-step explanation:

Chain rule to find the derivative,

We have to find the derivative of F(x)

If F(x) = f[g(x)]

Then F'(x) = f'[g(x)].g'(x)

Given function is,

y = \sqrt{2x+3}

Here g(x) = (2x + 3)

and f[g(x)] = \sqrt{2x+3}

\frac{dy}{dx}=\frac{d}{dx}(\sqrt{2x+3}).\frac{d}{dx} (2x+3)

y' = \frac{1}{2}(2x+3)^{(1-\frac{1}{2})}.(2)

   = (2x+3)^{-\frac{1}{2}}

y' = \frac{1}{\sqrt{2x+3}}

Therefore, it's true that we need to use the chain rule to find the derivative of the given function.

kvasek [131]

Answer:Mapping Rule A mapping rule has the following form (x,y) → (x−7,y+5) and tells you that the x and y coordinates are translated to x−7 and y+5. Translation A translation is an example of a transformation that moves each point of a shape the same distance and in the same direction.

Answer:

2/3

Step-by-step explanation:

\frac{3}{4} n =  \frac{1}{2}  \\  \\ multiply \: both \: sides \: by \:  \frac{4}{3}  \\  \\ \frac{ \cancel4}{\cancel3}   \times  \frac{\cancel3}{\cancel4} n = \frac{\cancel4 \:  \:  \red{ \bold2}}{3}   \times  \frac{1}{ \cancel2}  \\  \\n =  \frac{2 \times 1}{3 \times 1}  \\  \\ n =  \frac{2}{3}
