A laboratory has a 75-gram sample of radioactive material. The half-life of the material is 10 days. (This means that it
takes 10 days for half of the initial mass to decay.)
The formula below can be used to find m, the remaining
mass in grams, in terms of t, the number of 10-day intervals
the mass has been decaying.
75(0.5)^t
Based on the formula, what is the mass of the laboratory's
sample remaining after 30 days?

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.

it is true

step-by-step explanation:

all the combinations add up i used   calculator

option: d is the correct answer.

d) none of the above.

step-by-step explanation:

clearly from the figure attached to the question we could see that there is no shape given. hence without any shape given in the figure and after rotation we can't obtained a square pyramid.

since, to obtain a image we need a proper figure of the pre-image so that it can be transformed.

hence, the correct answer is:

d) none of the above.
