The number of vibrations in a piano string are inversely proportional to its length. a wire 1.25m long vibrates at 510 vibrations/second. to produce 450 vibrations per second, how long should a wire be made

On a piece of paper graph f(x)=5•(0.4)^x

What is true about the dilation? it is a reduction with a scale factor between 0 and 1. it is a reduction with a scale factor greater than 1. it is an enlargement with a scale factor between 0 and 1. it is an enlargement with a scale factor greater than 1.

Follow these steps using the algebra tiles to solve the equation −5x + (−2) = −2x + 4. 1. add 5 positive x-tiles to both sides and create zero pairs. 2. add 4 negative unit tiles to both sides and create zero pairs. 3. divide the unit tiles evenly among the x-tiles. x =
