<u>Part 1</u>
The gradient of the line is , so the equation is .
This means the system is
<u>Part 2</u>
Substituting in the coordinates (-3,11) and (2,1) into the equation of the parabola,
Subtracting the equations, we get 10=5a, and thus a = 2
Substituting a = 2 back into the system, we get b = -7
<u>Part 3</u>
The equation of the parabola is , and the turning point is at . Therefore, the value of y is -7
Answer:
Step-by-step explanation:
The option which is not a possible distance for the flight from Haiti back to Cuba is 43, because that number is far too low to be a possible option. The correct answer should be somewhere around 500km, which means that the remaining options are close to it, whereas 43 is not.
Answer:
m is the slope
Step-by-step explanation:
Answer:
112.98 square units
Step-by-step explanation:
Let's work backwards:
Circumference = 2πr
(37.68)/2π = r
Area = π
Area = π *
Area = 112.983 square units
