Answer:
See explanation
Step-by-step explanation:
A) the x-intercept is the solution because there are only x's in the equation when they are set equal to each other.
B) (-3, 8), (-3, 4)
(-2, 4), (-2, 4)***** this is the solution
(-1, 2), (-1, 4 1/8)
(0, 1), (0, 5)
(1, 1/2), (1, 12)
(2, 1/4), (2, 68)
(3, 1/8), (3, 516)
C) Graph them and show the intersection

Answer: 122 ft and 12.77 m
Step-by-step explanation:
First question answer = 100/cos35 = 122.07 = 122 ft
Second question answer = 12/sin70 = 12.77 m
Answer:
(b) domain: (-∞, ∞)
(c) f(x) = 3 only at x=1
(d) range: (-∞, 3]
Step-by-step explanation:
(b) The domain is the horizontal extent of the region over which the function is defined. The function f(x) is defined for all x, from -∞ to +∞. The arrowheads on the ends of the graph mean the graph extends to infinity in x and y directions from those points (y goes to -∞, while x goes to ±∞).
__
(c) Locate the horizontal grid line y=3 on the graph. Find all the points where it intersects the graph. There is only one: (1, 3). That is, x=1 is the only x-value for which f(x) = 3.
__
(d) The range of the function is its vertical extent. The graph of f(x) extends from y = -∞ up to y = 3, so that is the range.
Answer:
1.5051
Step-by-step explanation:
It is called a difference of squares because there are two things squared being subtracted. You can recognize it when there are two terms, subtraction between the two of them, and you know the square root of both
