Hello :
hello : <span>
1 ) if : x</span>ـــــــ> ± ∞
<span>
limf(x) = b ....(b</span>∈R) so : y=b is the equation of
the line horizontal asymptote.
<span>
2) if : x</span>ـــــــ>
a ...(a∈R)<span>
limf(x) = ± ∞
<span>so : x=a is the equation of the
line vertical asymptote.</span></span>

Answer:
1.5 inches/ week
Step-by-step explanation
Given
Height of he plant = 3in
If the plant grows by 2in every week
The rate of change = Height of plant/weekly increase
The rate of change = 3/2 = 1.5 inches/ week
Answer:
A=πr2
Step-by-step explanation:
Answer:
y=x+20
Step-by-step explanation:
we have to find the slope
y2-y1/x2-x1
3-2/23-22
1/1
y=1x+b
y-22 = 1(x-2) + b
y=x+20
Answer:
90π units²
Step-by-step explanation:
(refer to attached)
Total Surface are off a right cylinder = area of its ends + area of curved surface
Given radius, r = 3 units and height, h = 12 units
Area of 2 ends,
= Area of 2 circles
= 2 x πr²
= 2π (3²)
= 2π (9)
=18π units²
Area of curved surface,
= 2πrh
= 2π(3)(12)
= 72π units²
Hence,
Surface area = 18π + 72π = 90π units²
