A ball is at it maximum height when its velocity is zero. y = 4+30t - 16t^2 is the formula, where
V = V(0) -32t
0 = 30- 32t
t = 15/16 seconds when its velocity is zero.
It is not at its maximum height but is falling.
Answer:
X = -3/7
Step-by-step explanation:
Answer:
12.5π units²
Step-by-step explanation:
Area of a semi-circle = πr²/2
Radius = diameter/2
Radius = 5
Therefore, the area of the semi-circle = 12.5π units²
The triangles consist in rectangles ΔABD and ΔCDB are congruent triangles.
Given that,
To prove ΔABD ≅ ΔCDB.
<h3>What is congruent geometry?</h3>
In congruent geometry, the shapes that are so identical. can be superimposed on themselves.
Here,
consider ΔABD and ΔCDB
1. AB = CD [opposite sides of a rectangle]
2. ∠A = ∠C [each angle of the rectangle is 90°]
3. AD = BC [opposite sides of a rectangle]
ΔABD ≅ ΔCDB
Thus, Both triangles ΔABD ≅ ΔCDB are congruent triangles, hence proved.
