Answer:

The height of the baseball after 3.5 seconds is 31 feet.

Step-by-step explanation:

Consider the provided expression.

The height of a baseball, in feet, is represented by this expression, where t is time in seconds.

h=-16t^2+64t+3

To find the height of the baseball  after 3.5 seconds, substitute the value of t = 3.5 in above expression

h=-16(3.5)^2+64(3.5)+3

h=-16(12.25)+224+3

h=-196+227

h=31

Hence, the height of the baseball after 3.5 seconds is 31 feet.

Someone please help me with this algebra problem
nevsk [136]

Answer:

$110

Step-by-step explanation:

We are looking for the decrease in money per desk purchased. Because the x-axis is the number of desks purchased, what we have to find is the (opposite) of the slope. The formula to represent slope can be written as:

\frac{y_{2} -y_{1} }{x_{2}- x_{1} }

We can substitute the points given, (2, 480) and (5, 150) and simplify:

\frac{150-480}{5-2} =\frac{-330}{3} = -110

We would multiply by -1 because we are asking for the decrease, and negative increase is decrease. -1 * -110, gives us $110
