The speed s in m/s of an athlete can be modeled by the function
s=9.8 - 9.8e 0.8st where t is the time (in seconds) after the athlete
starts running. Graph this model and use the graph to estimate the
speed of the athlete 2 seconds after his launch. Round your answer to
the nearest whole m/s.
speed = m/s

step-by-step explanation:

the answer is:

the lateral area is equal to

to find the lateral area of the square pyramid, first we need to find the perimeter of the base, and then, find the lateral area using the following formulas:

where,

s, is the base length

slant height, is the height of a the side of the pyramid

we are given:

now, calculating the perimeter of the base, we have:

then, calculating the lateral area:

hence, we have that the lateral area is equal to
