Step-by-step explanation:

y = -½(x-3)²-1

This is the equation of a vertical parabola with vertex at (3,-1). The leading coefficient is negative, so the parabola opens downwards.

the surface area is 124cm²

step-by-step explanation:

length: 4cm

width: 9cm

height:   2cm

hi there!

step-by-step explanation:

a roof pitch is basically for every inch rise there is 12 inches run.

the height of the roof is also known as the rafter.

formula: rafter^2 = rise^2 + run^2

rafter^2 = 5^2 + 12^2

rafter^2 = 25 + 144

rafter ^2 = 169"^2

the height of the roof from the lowest point to the highest point is 169"^2.

hope this : )
