The potential energy, P, in a spring is represented using the formula P = A equals StartFraction one-half EndFraction b h. kx2. Lupe uses an equivalent equation, which is solved for k, to determine the answers to her homework. ASAP 20 POINTS
Which equation should she use?

k = 2Px2
k = k equals StartFraction one-half EndFraction P x squared. Px2
k = k equals StartFraction 2 P Over x squared EndFraction.
k = k equals StartFraction P Over 2 x squared EndFraction.

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.

2/3

step-by-step explanation:

thus, the first answer choice, y = sec x, is the correct one
