Question

PLEASE HELP GIVING THE BRAINLIEST!!!!!

Answer 1

Answer:

quadratic variation

inverse variation

frequency = 360  

Step-by-step explanation:

$h(x)=\frac{1}{2}x^2$

Here in h(x), we have x^2. x^2 always represents quadratic

x^2 at the top. so its is a quadratic variation

$xy = 12$

Divide both sides by x

so $y=\frac{12}{x}$

y is inversely proportional to x

so its inverse variation

length varies inversely as frequency, the equation is $g=\frac{k}{f}$

18-inch-long cello string vibrates 300 cycles per second.

g=18 and f=300, solve for k

$g=\frac{k}{f}$

$18=\frac{k}{300}$

5400=k

$g=\frac{5400}{f}$

length g= 15

$15=\frac{5400}{f}$

multiply by f on both sides and divide both sides by 15

f=360

frequency = 360
