Answer:
Step-by-step explanation:
Let's FOIL this out and get it into standard quadratic format:
. The lack of a linear term in the middle means therewas no upwards velocity, consistent with the object being dropped straight down as opposed to thrown up in the air tand then falling in a parabolic path. The -4.9t² represents the acceleration due to gravity, and the 490 represents the height from which the object was dropped. The constant in a quadratic that is modeling parabolic motion always represents the height from which the object was dropped (or launched). That's how you know.
X intercept is (14/9,0)
Y intercept is (0,-2)
Hey there!
Since we don't have values for b, d, and r, we can't get a specific number for the value of a, if that makes sense. It'll be represented by these variables.
To solve, we need to make sure the equation looks like a = ? .
Subtract b from each side of the equation.
<u>a = dr - b </u>
Now we have solved for a.
Hope this helps!
It is C. 2/3 because the original fraction would be 4/6, and if you simplify that, you get 2/3
