The sample loses 1/3of it’s mass every ___ days

The sample loses of its mass every days.

Step-by-step explanation:

Expression that shows the relation between final mass of the element after 't' days is,

M(t) =

If M(t) = two third of the initial mass [After the loss of one third of the initial mass remaining mass of the element = 1 - = rd of the initial mass]

By comparing powers on both the sides

3t = 1

t = day

Therefore, The sample loses of its mass every days.

step-by-step explanation:

i found the koficent of the linear function and i foun c acordind to the strict formula y=kx+c and then i took 2 as an x and replacet it on the formula i found and then foun the y

alright so i think for this one it would to draw it out. this may be hard for me to try and draw, but i will do my best on here:

        r

  /       |     \

notice how it forms 2 triangles inside one bigger triangle.

so if we know the angle spr is the same as psr that is saying the measure of angle p is the same as angle s. this means the big triangle psr is either isosceles or equilateral. in both cases, the triangle is perfectly symmetrical when split down the middle, which is in this case rq. because we know it is perfectly symmetrical on both sides, we know that the two triangles inside the bigger one are equal.
