3(2)-18=-12
6-18 = -12
-12 = -12
Answer:
Step-by-step explanation:
The formula for determining the the area of a sector is expressed as
Area of Sector = θ/360 × πr²
Where
θ represents the central angle.
π is a constant whose value is 3.14
r represents the radius of the circle.
From the information given,
The central angle is π/7 radian. Converting to degrees, it becomes
π/7 × 180/π = 180/7 = 25.714 degrees.
Area of sector = 77 square meters
Therefore
77 = 25.714/360 × 3.14 × r²
77 = 0.2243r²
r² = 77/0.2243 = 343.29
r = √343.29 = 18.53 meters
Answer:
The equation of the line y= 5x+1. Line that is parallel to the function given should have the same slope as the equation which is 5. We use the point-slope form in order to find the second equation that contains the point (4,5).
y - 5 = 5(x-4)
y = 5x - 20 +5
y≈ 5x -15
Answer:
253,000
Step-by-step explanation:
- Plug the above answers in: 2.1 × 100,000 + 4.3 × 10,000
- 2.1 × 100,000 = 210,000
- Plug 210,000 in: 210,000 + 4.3 × 10,000
- 4.3 × 10,000 = 43,000
- Plug 43,000 in: 210,000 + 43,000
- 210,000 + 43,000 = 253,000
