Answer:
Step-by-step explanation:
Given A = 5i + 11j – 2k and B = 4i + 7k, the vector projection of B unto a is expressed as
b.a = (5i + 11j – 2k)*( 4i + 0j + 7k)
note that i.i = j.j = k.k =1
b.a = 5(4)+11(0)-2(7)
b.a = 20-14
b.a = 6
||a|| = √5²+11²+(-2)²
||a|| = √25+121+4
||a|| = √130
square both sides
||a||² = (√130)
||a||² = 130
<em>Hence the projection of b unto a is expressed as </em><em></em>
Answer: B. binomial.
Step-by-step explanation:
1. You can classify polynomials based on the number of terms the polynomial has:
- If it has one term is classified as a monomial.
- If it has two term is classified as a binomial.
- If it has three terms is classified as a trinomial.
2. The polynomial has two terms. Therefore, the correct clasification is: binomial.
3. Then, the correct answer is the option B.
