The answer is:
The correct option is the option D
<h2>
Why?</h2>
To calculate the acceleration, we need to use the following formula that involves the given information (initial speed, final speed, and time).
We need to use the following free fall equation:
Where:
is the final speed.
is the initial speed.
g is the acceleration due to gravity.
t is the time.
We are given the following information:
Then, using the formula to isolate the acceleration, we have:
Now, substituting we have:
Therefore, since we are looking for a magnitude, we have that the obtained value will be positive, so:
Hence, the correct option is the option D
Have a nice day!
Answer:
y = -0.07x2 + 3.07x
Step-by-step explanation:
For each plant we add, there is a decrease of 70 grams for all plants from the inicial value of 3 kg of beans.
So, for 2 plants, we have (3 - 0.07) * 2
For 3 plants, we have (3 - 2*0.07) * 3
For x plants, we have (3 - (x-1)*0.07) * x
So we can model the final result of the amount of beans 'y' with the equation:
y = (3 - (x-1)*0.07) * x
y = (3 - 0.07x + 0.07) * x
y = (3.07 - 0.07x) * x
y = -0.07x2 + 3.07x
(In this equation we have a = -0.07, b = 3.07 and c = 0)
If you plug in the # the only one that is correct is y-8=-0.2(x+10)
169 miles * 5280 ft/ mile = 892320 ft
3 hours * 60 minutes/1 hr = 180 minutes
3 hrs 30 minutes = 180 minutes + 30 minutes = 210 minutes
169 miles/ 3 hrs 30 minutes = 892320 ft/ 210 minutes = 4249.1 ft/ minutes
