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

posting others as picture (have an account with Symbolab to help me as well. Just taking too long to type in the step by step if you need it. all pictures have the decimal result.
Answer:
The answer is 7.96×10⁷ .
Step-by-step explanation:
As the decimal moves to the <u>l</u><u>e</u><u>f</u><u>t</u> , you have to add one more power to the base 10 :
e.g
7 960 000.0 = 7 960 000×10¹
796 000.00 = 796 000×10²
79 600.000 = 79 600×10³
7 960.0000 = 7 960×10⁴
796.00000 = 796×10⁵
79.600000 = 79.6×10⁶
7.9600000 = 7.96×10⁷
* Take note :
0 < a < 10 ('a' must be greater than 0 but smaller than 10)

Answer:
A) car one is linear because it decreases the same amount every year.
car two decreases by the same ratio so it's exponential.
B) for car one y = -6,000x + 38,000 (y is the value after x years, -6,000 is what it changes by every year, and 38,000 is the amount of year 0)
for car two y = (44,000) (17/20)x-1 (y is the value after x years, 44,000 is the amount on year 0, and 17/20 is the ratio)
C) after 5 years car one will be 8,000
after 5 years car two will be about 16,860
