Answer:
D) undefined
Step-by-step explanation:
The tangent function is undefined for odd multiples of pi/2.

<em>Additional comment</em>
The terminal point on the unit circle of the ray at angle 3π/2 is (0, -1). The tangent is the ratio of the y-coordinate to the x-coordinate: y/x = -1/0. It is undefined at that point.
Answer:
440 ft
Step-by-step explanation:
Perimeter(p) of a rectangle is 2l + 2w
Where 'l' is the length and 'w' is the width.
p = 2(96ft) + 2(124ft) = 192 ft + 248 ft = 440 ft
Answer:
(a) 93.19%
(b) 267.3
Step-by-step explanation:
The population mean and standard deviation are given as 502 and 116 respectively.
Consider, <em>X</em> be the random variable that shows the SAT critical reading score is normally distributed.
(a) The percent of the SAT verbal scores are less than 675 can be calculated as:
Thus, the required percentage is 93.19%
(b)
The number of SAT verbal scores that are expected to be greater than 575 can be calculated as:
So,
Out of 1000 randomly selected SAT verbal scores, 1000(0.2673) = 267.3 are expected to have greater than 575.
Option B is your answer.
3/5x - 5 + 5/5x - 4 = - 1
8/5x - 9 = - 1
8/5x = - 1+ 9
8/5x = 8
Multiply both sides by 5/8 (the reciprocal of the coefficient) to isolate variable X.
(5/8)(8/5x) = 8(5/8)
x = 40/8
x = 5
