Multiply: –c2(3c – 2) Apply the distributive property. Multiply. –c2(3c) + (–c2)(–2) c3 + c2

H (t) = - 16t ^ 2 + 16t + 480
To address this, we first set the polynomial to zero to find its roots.
So we have:
0 = -16t ^ 2 + 16t + 480
This leads us to the roots of the polynomial:
t1 = -5
t2 = 6
We disregard the negative root since time cannot be less than zero.
Final answer:
Rose takes about
t = 6 seconds

Detailed breakdown:

Considering a rectangle measuring 3cm by 4cm with a circle of 1 cm diameter within it:

The area of the shaded section equals Area of Rectangle minus Area of Circle

The area of a rectangle is calculated as Length multiplied by Width

The area of the circle is

Area of shaded region = 12 - 3.142
