If your trying to figure out (x) then the answer would be 7 because 7 times 2 is 14 and then 14 minus 3 would be 11
Step-by-step explanation:
(2, -3) is in the 4th quadrant. By the counter clockwise rotation of 90° around the origin, it will be in the 1st quadrant.
Any point in the 1st quadrant has both positive x and y coordinates.
So the answer is (3, 2).
Using an exponential function, it is found that:
a) 
b) 37.5 grams of the gas remains after 3.8 days.
c) The amount remaining will be of 10 grams after approximately 11 days.
<h3>What is an exponential function?</h3>
A decaying exponential function is modeled by:

In which:
- A(0) is the initial value.
- r is the decay rate, as a decimal.
Item a:
We start with 75 grams, and then work with a half-life of 3.8 days, hence the amount after t daus is given by:

Item b:
This is N when t = 3.8, hence:

37.5 grams of the gas remains after 3.8 days.
Item c:
This is t for which N(t) = 10, hence:







The amount remaining will be of 10 grams after approximately 11 days.

No it can’t because calculating the perimeter, you would have to add all sides of the rectangle. If you added 11 + 11 + 24 +24, the perimeter would be 70 not 60.
The answer is 24 the first choice
