A sample of a radioactive isotope had an initial mass of 370 mg in the year 2007 and decays exponentially over time. A measurement in the year 2012 found that the
sample's mass had decayed to 80 mg. What would be the expected mass of the
sample in the year 2020, to the nearest whole number?

it is not that hard all u have to do is plot the graph

step-by-step explanation:

sas (side angle side)

aa (angle angle)

sss(side side side)

sas find two sides with an angle in between

aa is finding two angles and the third will add up to 180

sss find all sides

step-by-step explanation:

multiple all that

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

have a nice day!
