Help me please?!?!? Giving brainly!
Igoryamba

Answer:

Multiply input by 4.

Step-by-step explanation:

So, all we have to do is find the difference between the input/output.

So for the first one.

4y=1x

Divde both sides:

1y=1/4x

Next we have 16y=4x

Divide both sides:

1y=1/4x

Ok, so we now know that y is 1/4x

Or in otherwords, 4x is 1y.

Remember x is input, and y is output.

So we can think of this as the input times 4 equals the output.

This seems to be the second answer.

Hope this helps!

What is the value of n in the equation 0=18+128n^2?
lbvjy [14]

Answer:

\large\boxed{\text{no soltion in the set of real numbers}}\\\boxed{n=-\dfrac{3}{8}i\ \vee\ n=\dfrac{3}{8}i\ \text{in the set of complex numbers}}

Step-by-step explanation:

18+128n^2=0\qquad\text{subtract 18 from both sides}\\\\128n^2=-18\qquad\text{divide both sides by 128}\\\\n^2=-\dfrac{18}{128}\\\\n^2=-\dfrac{18:2}{128:2}\\\\n^2=-\dfrac{9}{64}

We find the length of AD using the similarity of right triangle property. See image attached.

AD² = BD × CD
AD² = 9 × 36
AD² = 324
AD² = 18²
AD = 18

The length of AD is 18 units
