Help what polynomials are there??

Mathematics
1 answer:
N76 [4]3 years ago
8 0

Answer:

All of them are polynomials except c.

Step-by-step explanation:

Polynomials are in the form:

a_0+a_1x+a_2x^2+a_3x^3+a_4x^4+a_5x^5+a_6x^6+\cdots +a_nx^n

You can see here there are no extra symbols like square root, cube root, absolute value, and so on on the variable x...

We also don't have division by a variable.  All the exponents are whole numbers.

a) While it has a square root, it is not on a variable so a is a polynomial.  The exponents on the variables are whole numbers.

b) b is a polynomial also because all the exponents are whole numbers.

c) This is not a polynomial because there is a square root on a variable.

d) This is a polynomial.  All the exponents are whole numbers.

Answer:

(a) α = 60°, β = 30°

(b) α ≈ 67.4°, β ≈ 22.6°

Step-by-step explanation:

I'll do (a) and (b) as examples.  Make sure your calculator is set to degrees, not radians.

(a) For α, we're given the opposite and adjacent sides, so use tangent.

tangent = opposite / adjacent

tan α = √300 / 10

tan α = √3

α = 60°

Since angles of a triangle add up to 180°, we know that β = 30°.  But we can use tangent again to prove it:

tan β = 10 / √300

tan β = 1 / √3

tan β = √3 / 3

β = 30°

(b) For α, we're given the adjacent side and the hypotenuse.  So use cosine.

cos α = adjacent / hypotenuse

cos α = 15 / 39

cos α = 5 / 13

α ≈ 67.4°

Again, we know that β = 22.6°, but let's show it using trig.  We're given the opposite side and hypotenuse, so use sine:

sin β = 15 / 39

sin β = 5 / 13

β ≈ 22.6°
