Answer:
There will be 88.6% of her bone mass remaining when she returns to earth.
Step-by-step explanation:
According to the problem, the astronaut will have 2% less bone mass than at the beginning of that month. So let's say is her original bone mass. In that case, her bone mass after the first month will be:
on the second month, her bone mass will be:
on the third month, her bone mass will be:
and so on, we can see a pattern here. The formula for her remaining bone mass can be generally written like this:
where n is the number of months, so after 6 months, her remaining bone mass will be:
that 0.886 gives us the percentage as a decimal number. When turned into a percentage we get that:
There will be 88.6% of her bone mass remaining after 6 months.
Answer:
A
Step-by-step explanation:
You can eliminate B and D because it’s using , but the question is asking
. So it’s either A or C. They are both written correctly, but out of the two, A is correct because just that x ≠
part of it is what makes it true.
The reason being is that the only thing that won’t make true is when the denominator equals 0, because anything divided by 0 is undefined. So, when you plug
for x in the denominator you get:
. The
part just turns into 7, and 7 - 7 is 0. So you don’t want x to equal
.
<u>So the answer is A:</u> ,
