Step-by-step explanation:
the circumference of a wheel is one revolution
so
formula: circumference=π*diameter
D=26cm (13*2 to find the whole length from one end to other)
so you'll do 3.14*26 equals 81.64
one revolution=81.64
30 revolutions=2,448.3 inches (times by 30 with 81.64)
Y = xe^x
dy/dx(e^x x)=>use the product rule, d/dx(u v) = v*(du)/(dx)+u*(dv)/(dx), where u = e^x and v = x:
= e^x (d/dx(x))+x (d/dx(e^x))
y' = e^x x+ e^x
y'(0) = 1 => slope of the tangent
slope of the normal = -1
y - 0 = -1(x - 0)
y = -x => normal at origin
A. 0.250006, 0.250007, 0.250008
b. 0.3330001, 0.3330002, 0.3330003
Answer:
16
Step-by-step explanation:
Substitute s = - 3 into the expression
7 - 3(- 3) = 7 + 9 = 16
