For this case, the first thing you should know is that a number in scientific notation is a number of the form:
Where,
a: is a number between 1 and 10
b: is the exponent of the scientific notation.
We have then that the number that is in scientific notation written correctly is:
Answer:
The correct option about squaring the binomial is that B. The student is wrong. There is a missing term.
<h3>How to use binomial theorem?</h3>
We want to square a binomial and using pascal's triangle in binomial theorem, we know that; (x + a)² will follow the pattern;
1x²a⁰ + 2a¹x¹ + 1x⁰a²
Thus, we can say that the expression (x + 3)² will give us;
x² + 2(3x) + 9a²
= x² + 6x + a²
Thus, we can say that the correct option about squaring the binomial is that B. The student is wrong. There is a missing term.
Complete Question is;
A student is instructed to square a binomial, and gets the result shown. Choose the correct description of the student's work. (x + 3)² = x² + 9 Choose the correct answer below.
A. The student is wrong. You cannot square a binomial, only monomials.
B. The student is wrong. There is a missing term.
C. The student is correct. Each given term is squared.
D. The student is wrong. The student should add the threes instead of multiplying them.

#SPJ1
Answer: 16.33 feet/s
Explanation:
1) Data:
a) circular motion
b) revolutions: 12 rpm
c) r = 15 feet
d) v = ?
2) Formulae:
angular velocity: ω = number of rpm × 2π / 60 seconds
linear velocity: v = ω × r
3) Solution:
ω = 12 × 2π / 60 s = 0.4π rad / s
v = 0.4π rad / s × 13 feet = 5,2 π feet / s ≈ 5,2 (3.14159) feet / s = 16.33 feet/s.
That is the answer.
