Answer:
64.7 degrees
Step-by-step explanation:
9.3/4.4= 2.1136
tan^-1(2.1136)=64.7
Radiologically, half lives describe the amount of time it takes for half the amount of the radioactive substance to decay. If you had 100g of a radioactive substance with a half life of one week, in seven days, only 50g would remain, and after another week, only 25g.
Fifteen days contains three half lives since the half life is 5 days long. Divide the starting amount by 2 for each half life that passes.
600g - 300g (1 HL) - 150g (2 HL) - 75g (3 HL)
So, only 75g of Bismuth-210 would remain after 15 days.
Sharon's revenue was
25×$3 = $75
The difference between her revenue and her cost was
$75 - 10 = $65
Sharon made $65 profit on bracelet sales.
Answer: B
Step-by-step explanation:
Answer:
Domain is the set of all possible input values is any relation. It means the output value in a function depends upon each member of domain. Domain value vary in different mathematical problems and depends upon the function for which is it solved. If we talk about cosine, then domain is the set of all possible real numbers either above the 0 value or below the 0 value, it could also be 0. While for square root, the domain value could not be less than 0, it should be minimum 0 or above 0. In other words, you can say that domain of square root is always 0 or positive value. For complex and real equations, the domain value is a subset of complex or real vector space. If we want to solve a partially differential equation for finding the value of domain, then your answer should lie within three dimensional space of Euclidean geometry.
