Area of triangle ABC can be found using the formula ¹/₂ × b × c × sin (A)
Substitute b = 9, c = 7, and m∠A = 66° into the formula gives
Area = 9 × 7 × sin 66° = 57.55
ANSWER: D
Answer:
The answer to your question is 2 seconds
Step-by-step explanation:
Data
function y = -14x² + 56x
maximum height = ?
Process
1.- Find the derivative of the function
y' = -28x + 56
2.- Equal to zero the result
-28x + 56 = 0
3.- Solve for x
-28x = - 56
x = -56/-28
x = 2
4.- Conclusion
It takes to the ball 2 seconds to reach the maximum height.
Your answer is c for the graph
