Answer:

Learn to find the sine, cosine, and tangent of 45-45-90 triangles and also ... Until now, we have used the calculator to evaluate the sine, cosine, and tangent of an angle. However, it is possible to evaluate the trig functions for certain angles without ... This is because there are two special triangles whose side ratios we know!

Ancient Greeks

Beginning in the 6th century BC with the Pythagoreans, with Greek mathematics the Ancient Greeks began a systematic study of mathematics as a subject in its own right. Around 300 BC, Euclid introduced the axiomatic method still used in mathematics today, consisting of definition, axiom, theorem, and proof.

Answer:

  (c)  27x^11 +51x^7 +9x^6 -60x^5 +17x^2 -20

Step-by-step explanation:

As with many multiple-choice questions, you only need to look at something that will discriminate the correct answer from the wrong one.

The highest-degree product term is the product of the highest-degree terms in the factors:

  (3x^5)(9x^6) = 27x^11

This matches choice C only.

_____

In case you're interested in actually performing the rest of the multiplication, the distributive property applies.

  (1 +3x^5)(17x^2 +9x^6 -20)

  = 1(17x^2 +9x^6 -20) +3x^5(17x^2 +9x^6 -20)

  = 17x^2 +9x^6 -20 +51x^7 +27x^11 -60x^5

Writing these terms in order of decreasing exponents gives ...

  = 27x^11 +51x^7 +9x^6 -60x^5 +17x^2 -20

Find the measure of the angle to the nearest tenth of a degree.
Digiron [165]

Answer:

Option B is correct.

Step-by-step explanation:

We need to find the value of S in cos S = 0.9092

cos S = 0.9092

To find value of S we will find cos^-1(0.9092) i.e

S = cos^-1 (0.9092)

S = 24.6 °

So, the measure of the angle to the nearest tenth of a degree of cos S = 0.9092 is 24.6°

So, Option B is correct.
