Answer:

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

Here n = 6, thus

sum = 180° × 4 = 720°

Thus each interior angle = 720° ÷ 6 = 120° and therefore

3x = 120 ( divide both sides by 3 )

x = 40 → A

Answer:

$f(x) = -2x^2 + 7x + 9$

Step-by-step explanation:

$f(x) = ax^2 + bx + c\\f(0) = 9 => c = 9;\\f(2) = 15 = 4a + 2b + 9 2a + b = 3\\f(3) = 9a + 3b + 9 = 12 3a + b = 1\\Subtract the second equation from the first:\\-a = 2 => a = -2; b = 7; c = 9\\f(x) = -2x^2 + 7x + 9$

Answer:

D.) He jogged 5 miles west and 12 miles north

Step-by-step explanation:

if you think of this as a right angled triangle, you are trying to work out the hypotenuse (longest side)

the formula is $a^{2}$ + $b^{2}$ = $c^{2}$

so, $5^{2}$ + $12^{2}$ = 169

169 = the $hypotenuse^{2}$

$\sqrt{169}$ = 13 miles
