what is the point-slope form of the equation for the line with a slope of -2 that passes through the point (4,-6)
2 answers:
Answer:
Step-by-step explanation:
Point-slope form of a line is where the slope is
and
is a point on the line.
We know both of those things so we have enough information without doing any math to do this problem. You just got to plug in.
So replace with -2,
with 4, and
with -6.
Like so:
.
You can simplify a little:

Answer with Step-by-step explanation:
Since we have given that
Initial velocity = 50 ft/sec =
Initial height of ball = 5 feet =
a. What type of function models the height (ℎ, in feet) of the ball after tt seconds?
As we know the function for height h with respect to time 't'.
b. Explain what is happening to the height of the ball as it travels over a period of time (in tt seconds).
What function models the height, ℎ (in feet), of the ball over a period of time (in tt seconds)?
if it travels over a period of time then time becomes continuous interval . so it will use integration over a period of time
Our function becomes,
For this case we must factor of the following expression:
By law of signs of multiplication it is fulfilled that:
So we have to:
Thus, by factoring we have:
