Answer:
D) 1
Step-by-step explanation:
When you start raising i to certain powers, you begin to notice a pattern.
This cycle repeats forever. Since 84 is a multiple of 4, i^84 must be 1. Hope this helps!
Answer:
Step-by-step explanation:
what
Answer:
23.54 m
Step-by-step explanation:
Applying
cos∅ = adjacent(A)/hypotenuse(H)
cos∅ = A/H................ Equation 1
make H the subject of the equation
H = A/cos∅............ Equation 2
Given: A = 15 m, ∅ = 25°
Substitute into equation 2
H = 15/cos25
H = 16.55 m
Also,
tan∅ = opposite(O)/Adjacent(A)
tan∅ = O/A............Equation 3
Make O the subject of the equation
O = Atan∅.......... Equation 4
Substituting into equation 4
O = 15(tan25°)
O = 6.99 m.
From the diagram,
The height of the goal post before snap = H+O
The height of the goal post before snap = 16.55+6.99
The height of the goal post before snap = 23.54 m
[x^3/(16+8)]-2
It says the quotient, dividing, of 'a number', which means a variable or unknown number, cubed, which means to the 3rd power, and 16 increased by 8 (which is 16+ 8) and at the beginning it says 2 less than which means -2.
