Find the slope of the tangent to y= -7Sin(x)+2cos(x) at x= 3π/4

1 answer:

6 0

Y = -7sin(x) + 2cos(x)
y = -7sin(3π/4) + 2cos(3π/4)
y = -7sin(9.42/4) + 2cos(9.42/4)
y = -7sin(2.355) + 2cos(2.355)
y = -7(0.03698381721) + 2(0.9993158646)
y = -0.2588867205 + 1.998631729
y = 1.739745009

A farmer counted a total of 9 eggs in 8 hens nest. What was the average number of eggs in each nest

maria [59]

Average=total/amount

Since the total eggs were 9, and you counted 8 hen nests,

9/8= 1.125
Because you cannot have 1.125 eggs, the average is about 1 egg.
