We are given the equation:
s(t) = gt² + v₀t + s₀
g=-4.9, v₀ =19.6 and s₀=24.5
plugging these values in the equation we get,
s(t)=-4.9t² +19.6t +24.5
Non when it hits the ground final height s(t) will be 0
0=-4.9t² +19.6t +24.5
first option is correct

Answer:
The Perimeter is 4.5in and the Area is 1.125in²
Step-by-step explanation:
Perimeter is gotten by adding up the length/height of every side of the polygon (1.5in + 1.5in + 0.75in + 0.75in), while the Area of a rectangle is gotten by multiplying the height and length. (1.5in × 0.75in)
He fourth one: 4,5,6,7,8...if it has those two bars || it means absolute value which basically means if its negative you just change it to a posotive :)
The height is 5 and 1/4 then the base is 2 and 1/2
You can convert these fractions into decimals and them multiply them to get your area.
