Answer:
a=240
b= 1.16
Step-by-step explanation:
The general form of exponential function for growth is given by:
y = a(1+r)ˣ
We can rewrite it by letting 1+r = b
y= abˣ
a from the given equation represents the initial number of birds, which is given by 240. Hence, a = 240
In (1+r), r is given as the rate of increase, which is given as 16% or 16/100=0.16.
For r = 0.15
b = 1+r
b = 1+ 0.16
b = 1.16
Substituting it in the initial equation:
y = abˣ
y = 240 (1.16)ˣ
where a = 240 and b = 1.16

Answer:1.1 ft^2
Step-by-step explanation:
Φ=55°
Radius=r=4
π=3.14
Area of segment=area of sector - area of triangle
Area of sector=Φ/360 x π x r x r
area of sector=55/360 x 3.14 x 4 x 4
Area of sector=(55x3.14x4x4) ➗ 360
Area of sector=2763.2 ➗ 360
Area of sector=7.7 ft^2
Area of triangle=0.5 x r x r x sinΦ
Area of triangle=0.5 x 4 x 4 x sin55
Area of triangle=0.5 x 4 x 4 x 0.8192
Area of triangle=6.6 ft^2
Area of segment=area of sector - area of triangle
Area of segment=7.7-6.6
Area of segment=1.1 ft^2
