Answer:
The area of the lawn is 68 .
Step-by-step explanation:
Area of lawn = Area of garden - (Area of triangle + Area of trapezium)
Area of garden = length x width
= 14 x 10
= 140
Area of triangle = x base x height
= x 3 x 8
= 12
Area of trapezium = (a + b) h
= (5 + 7) 10
= 60
So that;
Area of lawn = 140 - (12 + 60)
= 140 - 72
= 68
The area of the lawn is 68 .
Answer:
1.5 - it represents the time in seconds where the ball is highest
Step-by-step explanation:
There are 2 methods of approaching this.
The first method involves graphing, simply place into a graphing calculator and view the vertex. The horizontal line coming down from the vertex is the axis of symmetry (it splits the parabola in half).
The second method is finding the axis of symmetry (vertex) algebraically.
-b/2a is the equation used to find the x term of the vertex, and if we were to substitute our values in, we'd get -48/-32, giving us 1.5
Answer:
10
Step-by-step explanation:
since it is a - 10. you would add that to the other side. making it -50. then you divide it by -5. -50 ÷ -5 is 10. as 2 negatives make a positive
