5/3 cos(alpha) - 5/2 cos(phi) + 11/6 - cos(alpha - phi) = 0 a. solve the four-bar linkage problem for an input of alpha = 40degree by interval halving. remember that the angles must be expressed in radians. let the initial value of phi be 30 degree. use a convergence criteria of epsilon = |phi_1 - phi_2| = 0.1. hint: it will take over 20 iterations to obtain an answer for 

y = 0.77(x)

step-by-step explanation:

the jacket retains this value after 23% cut or retains 77% of original value. plug original 87 jacket price for x and the remaining value should be y.

step-by-step explanation:

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
