Answer:

90°

Step-by-step explanation:

= arccos(0/2184)

= arccos(0)

= 90°

Solve for x in the equation x squared + 11 x + StartFraction 121 Over 4 EndFraction = StartFraction 125 Over 4 EndFraction.
telo118 [61]

Answer:

x = -13 or 2

Step-by-step explanation:

x² + 11x + ¹²¹/₄ = ¹²⁵/₄

(x + ¹¹/₂)² = ¹²⁵/₄

x + ¹¹/₂ = ±¹⁵/₂

x = -¹¹/₂ ± ¹⁵/₂

x = -13 or 2

The graph of f(x) = (0.5)x is replaced by the graph of g(x) = (0.5)x − k. If g(x) is obtained by shifting f(x) down by 2 units,
sp2606 [1]
To shift a graph down by two units, -2 must beg added to the function.

Since g(x)=0.5x-k already, k=2, because it is already specified that the constant will be subtracted.
