Answer:
10 units and 157.84 units
Step-by-step explanation:
4
substitute t = 1 into the equation
h = - 16(1)² + 6 = - 16 + 6 = - 10
the value is negative since the ball travels down
the ball has travelled 10 units after 1 second
5
substitute t = 3.2 into the equation
h = - 16(3.2)² + 6 = - 16(10.24) + 6 = - 163.84 + 6 = - 157.84
the well is 157.84 units deep
Ok

The second #14.) x<2
Answer:
∠ A = 62°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
116° is an exterior angle of the triangle, then
3x - 13 + 2x + 4 = 116
5x - 9 = 116 ( add 9 to both sides )
5x = 125 ( divide both sides by 5 )
x = 25
Then
∠ A = 3x - 13 = 3(25) - 13 = 75 - 13 = 62°
Solve:-
0.36 × 100 = 36
36/100
0.36 = 36/100 = 18/50 = 9/25
