If P(x, y) is the point on the unit circle defined by real number 0, then cot 0=
denpristay [2]

Answer:

  x/y

Step-by-step explanation:

The question is badly worded, to the point of being impossible to answer as it is written.

We presume the given point (x, y) is (cos(θ), sin(θ)). The definition of cot(θ) is cos(θ)/sin(θ), so matches x/y with our assumed definitions of x and y.

Kenisha uses the Fermi process to estimate the number of dollar bills that would cover her driveway. Her driveway is rectangular
shepuryov [24]

Answer:

option A

9×10^4/2×10^2

Step-by-step explanation:

Given in the question,

length of dollar bill = 6

width of dollar bill = 3

area of dollar bill = L x W

                            = 6 x 3

                            = 18inches²

length of driveway = 30

width of driveway = 20

area of driveway = L x W

                             = 30 x 20

                             = 600 ft²

1 ft² = 144 inches²

600 ft² = 86400 inches²

Number of dollar bills that would cover Kenisha driveway = 86400 / 18

                                     

Which can also be written as

86400 = 9 x 10^{4}

18        = 2 x 10²

\frac{9x10^{4} }{2x10^{2} }
