A forest ranger is watching the progress of a forest fire spreading towards her from the top of a 3790-foot mesa. In 2 minutes, the angle of depression to the leading edge of the fire changes from 10.47∘ to 12.54∘. (a) How many feet does the fire advance during the 2 minutes that the ranger is observing it?

(b) At what speed (in MILES PER HOUR) is the fire spreading towards the ranger?

answer: answer is c!

ok i got to organize the

3/15 and 12/55

3*

aha

3*4 equals 12 but not

a: no

b:

8/24 12/35

no

gautie

it's c

5/18 = 25/90

5*5=25

18*5 = 90

hope that you!

one more happy customer!

< 3

step-by-step explanation:

47 - 90 = 43

43 - 180 = x

x = 137

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables

your answer is a

an = 22 + (n-1) *6

110 seats

step-by-step explanation:

an=a1+(n-1)(d)

a1 = 22   this is the first item in the sequence

d =6   this is how the sequence goes up

a)   an = 22 + (n-1) *6

b) a12 = 22 + (12-1) *6

    a12 = 22+11*6

  a12 = 22 +88

  a12 = 110
