Answer to number 16 is 27 and 17 is 2
If the number before the place you are rounding to is a 5 or more you round up but if it is a 4 or below it stays the same so the answer is 28,000,000
Exercise 1:
The exponents are wrong: when you divide two power, you subtract the exponents:

Exercise 2:
The function represents a growth rate of 300%! 3% is actually written as 0.03, so the correct function is

Exercise 3:
To factor a quadratic equation, we have to find the roots. Once you have the roots
, you can factor the expression as 
In this case, the solutions are
, which yields the factorization

Exercise 4:
When you multiply two powers of the same base, you add the exponents:

So, in your case, you have

Based on the CPCTC theorem, the congruences that are true about the given triangles are:
B. ∠K ≅ ∠S
C. KL ≅ ST
D. JK ≅ RS
<h3>What is the CPCTC Theorem?</h3>
According to the CPCTC theorem states that if two triangles are congruent to each other, then, all their corresponding parts will be congruent to each other.
Given that triangles JKL and RST are congruent to each other, therefore:
∠J ≅ ∠R
∠K ≅ ∠S
∠L ≅ ∠T
JK ≅ RS
KL ≅ ST
JL ≅ RT
Therefore, the congruences that would be true by CPCTC are:
B. ∠K ≅ ∠S
C. KL ≅ ST
D. JK ≅ RS
