Answer: V7 = $50,000 × 1.17 + $5,000 × FVIFA10%,5 × 1.12 - $10,000 × FVIFA10%,2
= $113,371.71
Answer:
Step-by-step explanation:
step 1
Find the slope of segment HI
The formula to calculate the slope between two points is equal to
we have
H (-4,2), and I (2,4)
substitute the given points
simplify
step 2
Find the slope of the perpendicular line to segment HI
we know that
If two lines are perpendicular, then their slopes are opposite reciprocal (the product of their slopes is equal to -1)
we have
so
step 3
Find the midpoint segment HI
we know that
The formula to calculate the midpoint between two points is equal to
we have
H (-4,2), and I (2,4)
substitute
step 4
we know that
The perpendicular bisector of HI is a line perpendicular to HI that passes though the midpoint of HI
Find the equation of the perpendicular bisector of HI in point slope form
we have
substitute
step 5
Convert to slope intercept form
Isolate the variable y
step 6
Convert to standard form
where
A is a positive integer
B and C are integers
Adds 3x both sides
see the attached figure to better understand the problem
Answer:
The first golf ball went higher.
Step-by-step explanation:
The equation representing the height (in feet) of a golf ball t seconds after it is hit is:
And the graph represents the height of a second golf ball t seconds after it is hit.
From the graph it can be seen that the second ball reaches its maximum height, i.e. 100 feet, after 2.5 seconds.
Compute the height of the first ball after 2.5 seconds as follows:
After 2.5 seconds the first ball reaches a height of 140 feet.
This height may or may not be the maximum height.
But for the same time, the first ball goes higher that the second ball.
Thus, the first golf ball went higher.
