Answer:
44.1m
Step-by-step explanation:
we are given a quadratic function which represents the height and time of a baseball
we want to figure out maximum height of
the baseball
since the given function is a quadratic function so we have a parabola
which means figuring out the maximum height is the same thing as figuring out the maximum y coordinate (vertex)
to do so we can use some special formulas
recall that,
notice that, our given function is not in standard form i.e
let's make it so
therefore we got
our <em>a</em> is -4.9 and <em>b </em>is 29.4
so substitute:
remove parentheses and change its sign:
simplify multiplication:
simplify division:
so we have figured out the time when the baseball will reach the maximum height
now we have to figure out the height
to do so
substitute the got value of time to our given function
simplify square:
simplify mutilation:
simplify substraction:
hence,
the maximum height of the baseball is 44.1 metres

Answer:
$200
Step-by-step explanation:
To find Jeff's net worth, we will deduct all his debts (liabilities) from his assets (his properties).
ASSETS
Savings Account - $6000
Investments - $15000
Guitar - $1000
TOTAL - $22000
LIABILITIES
Student loans - $17000
Credit Card Debt - $1200
Outstanding car payment - $3600
TOTAL - $21800
NET WORTH = Assets - Liabilities
NW = $22000 - $21800
NW = $200
His net worth is $200.
