Answer:
A.
Step-by-step explanation:
Assuming the 3/8 markers are counting the lines on the number line, not the chunks in between the lines, there are 7 markers that are in the shaded area and another half distance between two markers at the end.
Domain:(-∞, ∞)
Range: {−32}
Answer:
aₙ = 75 x 0.2ⁿ⁻¹ or 75 x (1/5)ⁿ⁻¹
Step-by-step explanation:
a₁ = 75
a₂ = 75 x 0.2¹ = 75 x 0.2 ²⁻¹ = 15
a₃ = 75 x 0.2² = 75 x 0.2³⁻¹ = 3
.......
aₙ = 75 x 0.2ⁿ⁻¹ or 75 x (1/5)ⁿ⁻¹
A function is even if, for each x in the domain of f, f (- x) = f (x). The even functions have reflective symmetry through the y-axis. A function is odd if, for each x in the domain of f, f (- x) = - f (x). The odd functions have rotational symmetry of 180º with respect to the origin.
f (x) = (x + 5) ^ 2
f (x) = x ^ 2 + 10x + 25
f (-x) = (-x + 5) ^ 2
f (x) = x ^ 2 - 10x + 25
the function does not comply with the definitions.
The function is NOT even
The function is not odd
answer
neither
Answer:
Use law of sine
sin90/9=sinB/4
4sin90/9=sinB
sin^-1(4sin90/9)=(sinB)sin^-1
