Answer:
the function f is neither even nor odd
Step-by-step explanation:
f(x) = 3x⁵ - 9
we start by calculating f(-x)
f(-x) = 3(-x)⁵ - 9
= 3(-(x)⁵) - 9 (Since 5 is an odd number then (-x)⁵ = - x⁵)
= - 3x⁵ - 9
Then
f is not even because f(-x) = - 3x⁵ - 9 ≠ 3x⁵ - 9 = f(x)
f is not odd because f(-x) = - 3x⁵ - 9 ≠ -3x⁵ + 9 = -f(x)
7^3
That's how you right that in exponent form, I don't really know how to explain it.
Answer:
n = -7
Step-by-step explanation:
n -16 = -23
add 16 to both sides
n= -23 + 16
add -23 and 16 to get -7
n= -7
hope this helps
Answer:
6.7 cm
Step-by-step explanation:
To make use of the Law of Sines for finding b, you need to know the missing angle B. Since the sum of the angles of a triangle is 180°, you can find angle B as ...
B = 180° -82° -55° = 43°
Now, you put the numbers you know into the formula given and solve for b.
sin(A)/a = sin(B)/b
sin(55°)/(8 cm) = sin(43°)/b
Cross multiplying gives ...
b·sin(55°) = (8 cm)·sin(43°)
and dividing by the coefficient of b gives you ...
b = (8 cm)·sin(43°)/sin(55°) ≈ 6.7 cm
