Answer:

Step-by-step explanation:
Let the number be
.
Then,

This implies that;

We multiply both sides by
to obtain;



Or

I can’t understand why everyone complicates this question. It can be easily solved by similar triangles.
In this png, we have something to make sure.
∠B=∠DAB

(Yes, dab)
This also means AD=BD

This is our basic construction of D, which is going to help us.
∠ADC=∠DAB+∠B=2∠B=∠CAB

These are based on the fact that ∠A=2×∠B

Actually these conditions suffice. Because I am just proving that △ACD∼△BCA

Guessing you meant by a factor of 3... not 13 since none of the solutions are anywhere close to that.
to compress is to smoosh.
It's the equation of a line. If you smoosh it vertically the line becomes flatter and the slope smaller.
Essentially g(x) = 3f(x)
3y = 12x + 6
y = (12/3)x + 6/3
y = 4x + 2
F’(x)= -akxsinkx
F’’(x)= -a(kx)^2coskx
I’m really sorry if the answer turned out wrong but I tried my best!
All we really need to do here is to convert 2 cm to meters. There are 100 cm in 1 meter, so the appropriate cm to meters conversion factor is
1 meter
-----------
100 cm
Thus,
2 cm 1 m
-------- * ----------- = (1/50) m = 0.02 m or 2.0*10^(-2) m (answer)
1 100 cm
