You (safely) bungee jump from a 200-feet tall bridge in your town. Your distance above the water's surface depends on the time s
ince you jumped. Sketch a reasonable graph.
2 answers:
Using the function :
<span>h(t) = 200 - 16t^2
</span>
The output graph will be a parabola as shown in the graph attached.
<span>h(t) = 200 - 16t^2
</span>
The output graph will be a parabola as shown in the graph attached.
Answer:
Step-by-step explanation:
The vertical motion of the object is defined by using the height function h(t) such that :
h(t) = -16t² + vt + s , where t is the time instant , v is the initial velocity and s is the initial height of the object.
Now, the height of the bridge = 200 feet
So it would be the initial height ⇒ s = 200
Initially the speed is 0 because the body is in rest at time instant 0 sec.
Hence, the resultant equation is : h(t) = -16t² + 200
And the graph is attached below :

Answer:
26.25 cm²
Step-by-step explanation:
The area of the shaded part is the area of the shaded triangle subtract the area of the white triangle.
Since the triangles are similar then the ratios of corresponding sides are equal.
let the height of the white triangle be h, then
=
( cross- multiply )
12h = 90 ( divide both sides by 12 )
h = 7.5
shaded area = × 12 × 10 -
× 9 × 7.5 = 60 - 33.75 = 26.25 cm²
