Answer: This is a periodic relation.

Step-by-step explanation:

This is a periodic relation, that can be modeled with a sinusoidal relation, that relates the height as a function of time.

Then we can write this as h(t) = A*sin(C*t + F) + B

Where A is the amplitude, C is a constant that depends on the period, F is a phase shift, and B is the midpoint of the function.

2*A is the distance between the maximum height and the minimum height.

B is the middle height of the Femis Wheel.

14 more than 6 times a number is greater than or equal to 28

Studentka2010 [4]

Answer:

6x + 14 ≥ 28

Step-by-step explanation:

6 times a number (6x)

14 more than (so, add 14 to 6x)

greater than or equal to, so this symbol ≥

= 6x + 14 ≥ 28

For what value of k, the zeroes of x2 + kx + 12 will differ by 1?

asambeis [7]

Let a and b be the zeroes of x² + kx + 12 such that |a - b| = 1.

By the factor theorem, we can write the quadratic in terms of its zeroes as

x² + kx + 12 = (x - a) (x - b)

Expand the right side and equate the coefficients:

x² + kx + 12 = x² - (a + b) x + ab

Then

a + b = -k

ab = 12

The condition that |a - b| = 1 has two cases, so without loss of generality assume a > b, so that |a - b| = a - b.

Then if a - b = 1, we get b = a - 1. Substitute this into the equations above and solve for k :

a + (a - 1) = -k → 2a = 1 - k → a = (1 - k)/2

a (a - 1) = 12 → (1 - k)/2 • ((1 - k)/2 - 1) = 12

→ (1 - k)²/4 - (1 - k)/2 = 12

→ (1 - k)² - 2 (1 - k) = 48

→ (1 - 2k + k²) - 2 (1 - k) = 48

→ k² - 1 = 48

→ k² = 49

→ k = ± √(49) = ±7
