Answer:

Step-by-step explanation:
Given expression is
.
Now we need to multiply this using FOIL.
F = First 
O = Outside 
I = Inside 
L = Last 
Hence we get :

Answer:
The largest angle is 63
Step-by-step explanation:
Shows that one is 36 degrees larger: 63 - 36 = 27
Shows that the angles are complementary/Their sum is 90: 27 + 63 = 90
Answer/Step-by-step explanation:
Reference angle = θ
Opposite side = 11.9
Adjacent side = 10
Applying the trigonometric ratio, TOA, we have:
Tan θ = opp/adj
Tan θ = 11.9/10
θ = tan^{-1}(11.9/10)
θ = 49.9584509° ≈ 50.0° (to one d.p)
Apply pythagorean theorem to find AB:
Thus:
AB = √(11.9² + 10²)
AB = √241.61
AB ≈ 15.5 (to 1 d.p)
How many zeros does the function f(x) = 3x12 − 17x8 + 11x4 − 6x + 23 have?
<span>Answer: the third option (12 zeroes..). </span>
<span>Use ^ to denote an exponent.. </span>
<span>f(x) = 3x^12 - 17x^8 + 11x^4 - 6x + 23.. </span>
<span>We know from that fact that the number of zeroes (real or complex) in a polynomial is the same as the degree of the polynomial.. </span>
<span>The degree is the greatest/highest power of the terms, which in this case is 12 (since 12 is the greatest exponent..).. </span>
<span>The degree is 12, thus it means there are 12 zeroes.. </span>
