X" * 2.54cm/1"

Step-by-step explanation:

X in * \frac{2.54cm}{1 in}

Your unit multiplier is 1" = 2.54 cm

Multiply the variable by the unit multiplier so the inches cancel out.

3.) Write the equation of a quadratic function that is shifted down 4 and horizontally compressed by 1/5
sashaice [31]

Answer:

5x^2 - 4

Step-by-step explanation:

For shifted down a function you have to follow the next structured:

f(x) - c

In our case is:

x^2 - 4

Now for compressed or shrink a graph you have to multiply by a factor in the input something like this:

f(cx)

In our case is:

5x^2

Maybe you can think, why 5 and not \frac{1}{5} instead?. Well, when you multiply by \frac{1}{5} this dilate or stretch the graft because the output of each value is smaller, example:

f(x) = x^2\\g(x) = \frac{1}{5} x^2

Then evaluate for a number, for example 5:

f(5) = 25\\g(5) = 5

the output of g(x) is 5 steps a far from the answer of f(x) this in a graph is illustrate as a stretching.

So the opposite happen when you multiply by a integer number, the graph is compressed because the output take the "faster steps".

So combine the two transformation and get 5x^2 - 4

Will mark brainliest if done within 20 minutes of this being posted! NO LINKS NO FILES. Solve the radical equations and show you
Simora [160]

Step-by-step explanation:

5√x+3 = -20

÷5. : √x+3 = -4

square: x+3 = 16

-3: x = 13

√x+18 -2 = x -4

+2 : √x+18 = x -2

square: x+18 = x^2 - 4x +4

-18: x = x^2 -4x -14

-x : 0 = x^2 -5x - 14

foil: (x- 7) (x+2) = 0

x = 7, -2
