I believe the formula to find the height would be h= 2a/b and if you use that formula and plug in the area (21.7) of each triangle as well as the base (6) then you would get a height of 7.2 cm. I hope this is correct! :)

2) for N={1,2,3,4,5,6,7...n};

3) the condition 'the n-th term of a sequence is 60-8n' can be re-written as

aₙ=60-8n and analyzed

4) a₁=60-8*1=52; a₂=60-8*2=44; a₃=60-8*3=36; a₄=60-8*4=28; a₅=60-8*5=20; a₆=60-8*6=12; a₇=60-8*7=4; a₈=60-8*8= -4; a₉=60-8*9= -12; a₁₀= -20, etc., then

5) the larges term of the given sequence is a₁=52.

Arte-miy333 [17]

Answer:

As you can see,

a, if the list increases n time, the number of comparisons almost increases n^2 time.

b, use the rule from part a, you can see, "1000 items" means that list increased 100 times( original list is 10), so the number of comparisons would be expected to increase 100^2 times.

What is the effect on the graph of the function f(x)= x when f(x) is replaced with f(-x)
Nina [5.8K]
All the x values are made negative

X = 4

F(x) = 2x
F(4) = 2(4)
F(4)= 8

X = 4 (still)

F(-x) = 2(-x)
F(-4) = 2 (-4)
F(-4) = -8
