Answer asap ill give ! ’ a sample of radioactive material decays over time. the number of grams, y , of the material remaining x days after the sample is discovered is given by the equation y = 10(0.5)^x. what does the number 10 represents in the equation? a. the half-life of the radioactive material, in days b. the amount of the sample, in grams, that decays each day c. the time, in days, it will take for the samples to decay completely d. the size of the sample, in grams, at the time the material was discovered

d.  So y = 10 (.5)^x   the 10 is the initial amount of the sample at the time  it was discovered

Step-by-step explanation:

When we have an equation of the form

y = ab^x

a is the initial value at time x=0

b is the growth (or decay ) factor  ( 1 + or - percent)

and x is the time

So y = 10 (.5)^x   the 10 is the initial amount of the sample at the time  it was discovered

the correct answer is semicircle

step-by-step explanation:

the answer is semicircle because the shorter arc joining two points on the circumference of a circle is known as the minor arc, the larger arc is called the major arc, and a semicircle is a half circle, formed by cutting a whole circle along a diameter line.
