eimsori [14]

Answer:

Step-by-step explanation:

This is classic right triangle trig.  The height of the hill is 78.4 which serves as the side opposite the reference angle of 23 degrees.  The side we are looking for is the hypotenuse of that triangle.  The trig ratio that relates the side opposite a reference angle to the hypotenuse of the right triangle is the sin ratio.  Setting it up using our values:

sin(23)=\frac{78.4}{x}, where x is the unknown length of the hypotenuse.  Solving for x:

x=\frac{78.4}{sin(23)}

Make sure your calculator is in degree mode before entering this in.  You will get a length of the hypotenuse as 200.649 feet, so choice A.

A student concludes that for all values of x,x^2+x+1 produces a prime number. Which value of x serves as counterexample to prove
Dafna11 [192]

Answer:

j

Step-by-step explanation:

Substitute the given values into x² + x + 1 and check if result is prime

x = - 4

(- 4)² - 4 + 1 = 16 - 4 + 1 = 13 ← prime

(- 2)² - 2 + 1 = 4 - 2 + 1 = 3 ← prime

(- 3)² - 3 + 1 = 9 - 3 + 1 = 7 ← prime

4² + 4 + 1 = 16 + 4 + 1 = 21 ← not prime

x = 4 serves as a counterexample to disprove this conclusion
