Average acceleration can be calculated as (v - v₀) / Δt.
Here, v = 0 m/s, v₀ = 20 m/s, and Δt = 3.5 s.
Thus, a (average) = (0 m/s - 20 m/s) / 3.5 s = -20 m/s / 3.5 s =
= -5.7142857 m/s² ≈ - 5.71 m/s²

Answer:

Average acceleration = 5.714 meter per second²

Step-by-step explanation:

A ball is thrown upwards with an initial speed of 20 meters per second.

After 3.5 seconds, its speed drops to zero, indicating it has reached the peak height.

We now need to find the average acceleration during the ascent.

Thus, \text{Acceleration}=\frac{\text{Change in velocity}}{\text{Duration of motion}}

Acceleration = \frac{20-0}{3.5}

                       = 5.714 meter per second²

Answer:

Expiration Date: 1/17/2017

Expiration Time: 4:00am

Preparation Date: 12/3/2016

Preparation Time: 4:00am

Initial Usage Date: 12/7/2016

Detailed Breakdown:

An illustrative depiction of the question has been provided in an image format for clarity.

From the information given, it is noted that her store order arrived on 12/3/2016 at 4am, confirming that both the prep date and time are 12/3/2016 and 4am respectively. The product has a printed expiration date of 1/17/2017, logically indicating that its expiration time is also 4am, in line with the prep time; adding 24 hours leads us back to the same time on the expiration date. Furthermore, we were informed that she utilized the product on 12/7/2016, which marks the initial use date. Based on this information, we can summarize as follows:

Expiration Date: 1/17/2017

Expiration Time: 4:00am

Preparation Date: 12/3/2016

Preparation Time: 4:00am

Initial Usage Date: 12/7/2016

The flight path of a golf ball is modeled by the function, F (X) = -0.0 2X^2 Plus 6X, we are X represents the horizontal distanc
lawyer [12517]
Let’s tackle the problem. We know the formula for <span>the height of the ball is as follows:

</span>f(x)=-0.02x^{2}+6x
<span>
Here, x represents </span><span>the horizontal distance in yards that the ball has traveled in the air. Given that distance is always a positive value, we conclude that x must be greater than or equal to 0. Thus:

</span>x \geq 0<span>

The horizontal plane indicates the function's zero point, and since the ball cannot have negative height values, f(x) must also remain positive. Ultimately, the graph reveals that the suitable domain is:

</span>\boxed{0 \leq x \leq 300}<span>
</span><span>
</span>
