Answer:
300,000 8,000 800 i think sorry if i got it wrong
Step-by-step explanation:
The first statement is false. A square DOES have 4 right angles.
For this item, we let x be the number of hours she works out and y be the total number of bananas that she will be eating after the workout. The expression that best described the given above is,
y = 5 + 2x
5 is given as the y-intercept because of the initial condition.
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.
