There was a sample of 950 milligrams of a radioactive substance to start a study. Since then, the sample has decayed by 8.5% each year.
Lett be the number of years since the start of the study. Let y be the mass of the sample in milligrams.

step-by-step explanation:

. your answer will contain x - and y -terms. (1 point) x ( ¿¿ 2 − 7 ) 2 +( y 2 − 9 ) 2 √ ¿ 12. what is the distance from the directrix (the crocodile river) to the point ( x , y )? write this equation. your answer will contain a y -term.

v = 1/3 a^2h

step-by-step explanation:

the volume is 1/3 a^2h.

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.
