Answer:

t = 51°

Step-by-step explanation:

The total sum of a polygon's exterior angles is always 360°.

Add all of the given angles and equate it to 360°.

40° + 34° + 34° + 46° + (2t - 50°) + (2t - 50°) + 2t = 360° Collect like terms

154° + 2t - 50° + 2t - 50° + 2t = 360° Remove brackets and collect like terms

54° + 6t = 360° Isolate t by doing reverse operations in reverse BEDMAS

6t = 360° - 54° Subtract 54° from both sides

6t = 306° Divide both sides by 6

t = 51° Answer

Which set of ordered pairs represents a function?

stealth61 [152]

Answer: The answer would be the first choice.

Step-by-step explanation:

Remember that a function is where every INPUT has exactly ONE OUTPUT. That means for the coordinates (x, y), no pair could have an x value repeat. So, the first ordered row pair does not have any repeating x values, so it's the first answer.

3. There are 4 friends. A quarter of 4 is 25%. You can prove this by multipling 25% by 4 of the friends to get 100%. There is a 25% chance of Jonathon arriving first and a 25% chance that Michel will arrive second.

Apply division algorithm to find the quotient and remainder on dividing the polynomial 3 x^ + 4 x^ square + 6 x + 9 by x^ + 3x +

Ulleksa [173]

I suppose you mean

$\dfrac{3x^3+4x^2+6x+9}{x^2+3x+7}$

$3x^3=3x\cdot x^2$ , and if we multiply $x^2+3x+7$ by $3x$ we get $3x^3+9x^2+21x$ . Subtracting this from the numerator gives a remainder of $-5x^2-15x+9$ .

$-5x^2=-5\cdot x^2$ , and multiplying $x^2+3x+7$ by $-5$ gives $-5x^2-15x-35$ . Subtracting this from the previous remainder gives a new remainder of $44$ .
