If how much owen saves is x, 2x=y (jessie's amount of saved money) and
x-5=nick's amount of money =z
Since x+y+z=220, we plug 2x in for y and x-5 in for z, getting x+2x+x-5=220. Adding 5 to both sides, we get 4x=225 and by dividing by 4 we get x=225/4=61.25 dollars. 61.25-5=56.25=z=nick's money, and 61.25*2=122.5=jessie's saved money
Answer:
15
Step-by-step explanation:
let's put value of t in equation.
x = 2√t
x = 2√y
x/2 = √y
(x/2)^2 = y
y = x^2 /4
now let's differentiate it with respect to x.
dy/dx = 2x/4 = x/2
differentiating again wrt to x
d^2y/dx^2 = 1/2
