The pitch of the roof is given by the ratio of the rise to the run of the roof, which is the slope of the rafter

$The \ pitch \ of \ the \ roof \ is \ \mathbf {\dfrac{6}{13}}$

Please find attached the simple <u>diagram of the house</u> with all measurements labeled

The reason the above value for the pitch and the diagram are correct are as follows:

The given parameters are;

Width of the section of the house on which the gable of the roof is to be placed = 50 feet

Length of the over hang on the sides of the roof = 1 foot each

Total span of the roof = 52 feet

Horizontal length of each rafter, the run = 26 feet

The height of the ridge above the top of the frame, the rise = 12 feet

Required:

To find the pitch of the roof

To draw a diagram of the house showing measurements

Solution:

$Pitch = \dfrac{Rise}{Run}$

$Pitch \ (slope) \ of \ roof = \dfrac{12}{26} =\dfrac{6}{13}$

Please find attached the <u>diagram</u> of the house showing the measurements for the roof parameters and the section of the house where the gable roof is to be placed

A ball is thrown straight upward from a bridge and then falls all the way to the ground (past the

Digiron [165]

Answer:

t = 4.6 seconds

Step-by-step explanation:

The ball's height above the ground t seconds later is given by the function is given by :

$h(t)=-16t^2+48t+120$

We need to find time when the ball be 20 feet above the ground. It means h(t) = 20.

So,

$-16t^2+48t+120=20\\\\-16t^2+48t+100=0$

The above is a quadratic equation, the solution of this quadratic equation is given by :

$t=\dfrac{-b\pm \sqrt{b^2-4ac} }{2a}\\\\t=\dfrac{-b+ \sqrt{b^2-4ac} }{2a},\dfrac{-b- \sqrt{b^2-4ac} }{2a}\\\\t=\dfrac{-48+ \sqrt{(48)^2-4\times (-16)(120)} }{2\times (-16)} \dfrac{-48-\sqrt{(48)^2-4\times (-16)(120)} }{2\times (-16)}\\\\t=-1.62\ s, 4.6\ s$

So, at t = 4.6 seconds, the ball will be 20 feet above the ground.
