Write the formula for Newton's method and use the given initial approximation to compute the approximations x1 and x2. Round to six decimal places.f(x) = x2 - 20; x0 = 5
A. xn+1 = xn + 
; x1 = 4.500000, x2 = 4.472222
B. xn+1 = xn - 
; x1 = 5.500000, x2 = 3.472222
C. xn+1 = 
; x1 = 5.000000, x2 = 4.972222
D. xn+1 = 
; x1 = 4.500000, x2 = 4.472222

Provide an appropriate response.The function W(g) = 0.44g2 - 0.02g + 8.5 models the average weight in ounces for a mouse who is fed g grams of a special food per day. Use the function to find and interpret W(13). Average Weight of Mouse Fed Special Food
A. 13.96; the average amount of the special food that 13 mice should be fed is 13.96 ounces. B. 184.6; when a mouse is fed an average of 184.6 ounces of the special food per day, its weight will be at least 13 ounces. C. 82.84; 13 mice gained an average of 82.84 ounces per day when fed the special food. D. 82.6; when a mouse is fed 13 grams of the special food per day, its average weight is 82.6 ounces.
Solve the given differential equation.
+ 16y = cos 4x
A. y = c1 sin 4x + c2 cos 4x + 
x sin 4x + 
x cos 4x
B. y = c1 sin 4x + c2 cos 4x - 
x sin 4x
C. y = c1 sin 4x + c2 cos 4x + 
x sin 4x
D. y = c1 sin 4x + c2 cos 4x + 
x cos 4x
Decide whether the expression is or is not an identity.tan (A + ?) = tan A
A. Identity B. Not an identity
