Answer:
52.4.
Step-by-step explanation:
This is the difference of 2 squares:
a^2 - b^2 = (a - b)(a + b)
(7.62^2 - (2.38)^2
= (7.62 - 2.38)(7.62 + 2.38)
= 5.24 * 10
= 52.4
The factors of the equation
are 
Step-by-step explanation:
We need to factor the quadratic trinomial. 
We will do factorization by braking the middle term such that adding those number we get middle term (-3x) and multiplying those numbers we get (-18x^2)
Solving:

So, the factors of the equation
are

Answer:
- 5 min: 3,029,058
- 10 min: 3,398,220
- 60 min: 10,732,234
Step-by-step explanation:
The given function is evaluated by substituting the given values of t. This requires using the exponential function of your calculator with a base of 'e'. Many calculators have that value built in, or have an e^x function (often associated with the Ln function).
