Answer:

Step-by-steYou have two angles,

A=32°20'

B=57°40'

so, angle F at the fire, is 90°

d/5 = cosA = .845

d = 4.2 mi

If angle F had not been 90°, then using the law of sines,

d/sinA = 5/sinF

for this problem, sinF = 1p explanation:

What is the axis of symmetry of the function f(x)=-(x+9)(x-21)
Firlakuza [10]
Carry out the mult.:  f(x) = -[x^2 - 21x + 9x - 189] 

Combine like terms:  f(x) = -[x^2 - 12x - 189]
Eliminate the brackets [   ]:      f(x) = -x^2 + 12x + 189
Identify coefficients a, b and c:   a= -1, b=12, c=189

The equation of the axis of symmetry is    x = -b/(2a), which here equals

x = -(12)/[2(-1)], or     x = 6

This is also the x-coordinate of the vertex.  Plug x=6 into the original equation to calculate the y-coordinate.

Hi there please explain how to solve or factorise this as i dont know the formula plus how to do ?:)
nalin [4]

Steps:

  1. Writing down the equation. x^2 + 1 = 0.
  2. Subtract 1 from both sides. x^2 = -1
  3. Square root (I am going to use the abbreviation sqrt) on both sides. x = sqrt (-1)
  4. sqrt (-1) is simplified as i (or imaginary number). Because of the sqrt, it would be plus or minus.
  5. (x+i)(x-i) is your answer. If you are in a lower math class (mentioning 10th grade or below), you should just put no solution.
