A baseball is thrown into the air and follows a parabolic path given by the equation s = -16t 2 + v0t, where s is feet above gro

Alla [95]

Answer: 64 ft

Step-by-step explanation:

We are given the following equation that models the baseball's parabolic path:

$s=16t^{2}+V_{o}t$ (1)

Where:

$s$ is the ball maximum height

$t$ is the time

$V_{o}=64 ft/s$ is the initial height

With this information the equation is rewritten as:

$s=16t^{2}+(64)t$ (2)

Now, we have to find $t$ , and this will be posible with the following formula:

$V=V_{o}-gt$ (3)

Where:

$V=0 ft/s$ is the final velocity of the ball at the point where its height is the maximum

$g=32 ft/s^{2}$ is the acceleration due gravity

Isolating $t$ :

$t=\frac{V_{o}}{g}$ (4)

$t=\frac{64 ft/s}{32 ft/s^{2}}$ (5)

$t=2 s$ (6)

Substituting (6) in (2):

$s=16 ft/s^{2}(2 s)^{2}+(64 ft/s)(2 s)$ (7)

Finally:

$s=64 ft$

Part A

denis-greek [22]

Answer:

252/193

Step-by-step explanation:

According to the question

volume=36cm^3

Radius=3cm

Now

h= v/πr^2

=36/π*3^2

=36*7/193

=252/193cm

your car broke down and the final bill was $306.50. The part that was replaced cost $119 and the charge mechanics labor was 75 p

erastova [34]

Answer:

$\huge\boxed\text{Equation:}$ $\huge\boxed{\text{Equation: }119+75x=306.50}\\$

$\huge\boxed{\text{Hours worked on: } 2.5}$

Step-by-step explanation:

We can create an equation for this problem by converting the words to an equation.

The <em>flat fee</em> was $119. We then add $75 for every hour worked. This means that this becomes $119+75x$ . Since the total cost was $306.50, the equation is $119+75x=306.50$ .

We can now solve for x, the amount of hours worked, to find it’s value.

$119 + 75x = 306.5\\\\75x=187.5\\\\x = 2.5$

Hope this helped!
