Let "a", "b" and "с" be sides of the triangle ("с" is the longest side). The triangle will be:
right if a² + b² = c²
аcute if a² + b² > c²
obtuse if a² + b² < c²
We have a=2, b=√11 and c=√15
2² + (√11)² = 4 + 11 = 15
and
(√15)² = 15
15 = 15 ⇒ right triangle.
Hope this helps.
Answer:
It'll take the robot 8 minutes to complete one task
7.5 tasks will be completed in one hour
Step-by-step explanation:
Total time to complete 5 tasks is 2/3hr (40 minutes)
Time it takes to complete one task = 40 ÷ 5 = 8 minutes
Since the robot completes one task in 8 minutes, x tasks will be completed in 60 minutes.
x = 60 ÷ 8 = 7.5 tasks
44.8 L = 0.0448 kL so your answer is 0.0448 kL
Well, ok, the x intercepts aer where the function equals 0
also
if the x intercepts are r1 and r2 then the factored form of the function is
f(x)=a(x-r1)(x-r2) where a is a constant
well, we have it already in that form
f(x)=(x-3i)(x-3i)
the x intercept is at x=3i
standard form requires expansion
we expand to get
f(x)=x²-6i-9
Y = yo + Vot - (gt^2)/2
0 = 0 + 31t - 4.9 t^2
0 = -4.9 t^2 + 31t
Answer: option A.
