A superhero is rendered powerless when exposed to 60 or more grams of a certain element. A 650 year old rock that originally contained 600 grams of this element was recently stolen from a rock museum by the superhero's nemesis. The half-life of the element is known to be 200 years.
a) How many grams of the element are still contained in the stolen rock?
b) For how many years can this rock be used by the superhero's nemesis to render the superhero powerless?

it’s supposed to be -4+45=41

step-by-step explanation:

what graph

step-by-step explanation:

a, b, c, d are correct.

step-by-step explanation:

we have g(x) = 3 and are required to find which option is a translation of g(x).

now, 'translation' is a transformation which means to shift the function in any direction and the general form of translation is g(x) + k, where k is any real number.

so, according to the options we see that all are correct as they satisfy the general form of translation.

also, it can be seen from the graph below that the function g(x) = 3 is shifted from its position in all the four options.
