Answer: No, it is linear
Explanation: The constant is +8, meaning the y intercept is 8. Proportional lines go through (0,0), but this line goes through (0,8).
1. (4,1) is not a solution because when u sub it into the equation, it does not come out correct. It would be correct if it was (1,4).
2. C = 2.50d.....where C is the cost and d is the number of drinks bought. And if u pick any number for d, then u can solve for the cost (C).
Answer:
43 cm
Step-by-step explanation:
C = 2 * pi *r
86pi = 2 * pi *r
Canceling pi from each side
86 = 2r
Divide by 2
86/2 =2r/2
43 =r
Use the midpoint formula,
Step-by-step explanation:
Area of remaining paper
= Area of rectangle - 2 * Area of semicircle
= Area of rectange - Area of circle
= (4in * 8in) - (π * 2in * 2in)
= 32in² - 4πin²
= 19.44in². (A)
