Answer:
3.81 s
Step-by-step explanation:
Let's consider the following formula that represents the journey of a falling object.
d = 3 t + 5 t²
where,
- d is the distance measured in feet
- t is the time measured in seconds
We can find the time that it will take to travel 84 feet by replacing d = 84 in the equation.
84 = 3 t + 5 t²
5 t² + 3 t - 84 = 0
We have a = 5, b = 3 and c = -84. We apply the second grade solving formula.
x₁ = 3.81 and x₂ = -4.41
Since the time cannot be negative, the answer is t = 3.81 s
Answer:
9.22 meters
Step-by-step explanation:
The formula for a pyramid is (base * height) / 3. Therefore, because it's a square, the base is 16, and thus the height divided by 3 = 3. 3 * 3 = 9, so the height is 9. Now we have a right triangle.
If the base edge = 4, half of the base edge is 2. Applying the Pythagorean Theorem, 2^2 + 9^2 = x^2 so then 4 + 81 = x^2. The square root of 85 is approximately 9.22 meters.
