y= -4x² - 16x - 14


Take the coefficient of x² as the common factor

y = - 4(x² + 4x + 7/2)


Add (b/2)² to complete the square

y = - 4( x² + 4x + 2² - 2² + 7/2)


Complete the square

y = -4( (x + 2)² - 1/2)


Remove the bracket

y = -4(x + 2)² + 2


Answer: y = -4(x + 2)² + 2

Answer:

cos theta = adja/ hypo

adja=8

hypo=17

cos theta= 8/17=0.47

theta= cos^-1 0.47

theta=1.0815

to fine missing side, use Pythagoras

hypo²= oppo² + adja²

17²= oppo² + 8²

289-64=oppo²

oppo²=225

oppo=15

Answer:

  50 ft

Step-by-step explanation:

The side lengths in a 30-60-90 triangle have the ratios 1 : √3 : 2. The longest side is 2 times the length of the shortest side.

In this geometry, that means the length of the escalator is 2 times its height, so is ...

  x = 2(25 ft)

  x = 50 ft . . . . . distance a person travels
