<span>A(k)=2(k-1)-4
The parenthesis mean that it is subscript
the next term is
2(180)-4=356</span>
Answer:
6
Step-by-step explanation:
Using the sine ratio in the right triangle and the exact value
sin45° = , then
sin45° = = = ( cross- multiply )
hyp = 3 × = 3 × 2 = 6
Answer:
Mult. and div.
Step-by-step explanation:
Four operations are listed here. Mult. and div. must be performed first, followed by addition and subtraction.
Order of operations rules are actually more general than this. Anything (expressions) inside parentheses must be evaluated before other operations take place. Next come exponential functions, which are evaluated before mult. and div.
For an equation to be linear, the slope has to be the same/constant.
To find the slope (m), you use the slope formula:
and substitute in 2 points
(1 , 60) [x₁ , y₁] and (5 , 70) [x₂ , y₂]
or 2.5
Try a different point to see if the slope is the same:
(5, 70) and (20, 80)
or 0.6666666
Since the slopes are different, a linear equation can not be used
