2 answers:
Answer:
here t stands for time
Step-by-step explanation:
We know from second equation of motion
...........(1)
in this equation
s- represents displacement
u-initial velocity
a-acceleration
and t-time
In this question we have given
.............(2)
here h(t) represents height
on comparing equation 1 and 2 we found that
here t represents time

In A 4 year period, About 80,000 acres of coastal wetlands in United States are lost each year.
so, total area =80000 acres
total time = 4 years
now, we can use formula
total change in wetlands = ( total area)/(total time)
now, we can plug values
total change in wetlands is

Answer:
<h2> 112.3 square units</h2>Step-by-step explanation:
Find the sketch of the triangle attached.
Area of the triangle =
Given PQ = 20, PR = 12 and ∠QPR = 68°
Area of the triangle = 1/2 * 20 * 12 * sin68°
Area of the triangle = 120sin68°
Area of the triangle = 112.26 square units
Area of the triangle ≈ 112.3 square units (to the nearest tenth of a square unit)
