An element with mass 510 grams decays by 26.3% per minute. how much of the element is remaining after 7 minutes, to the nearest 10th of a gram?

A decay rate of 26.3% per minute means that for every minute that passes, there remains 73.7% of the amount of the substance available at the end of the previous minute.

If is the starting amount, and is the amount left after minutes, then

and so on, such that

We have grams at the start, so after 7 minutes we're left with

the 2 figures are congruent bc if you reflect abcd over the y axis then over the d axis the figures overlap

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
