EMERGENCY A search and rescue team is airlifting people from the scene of a boating accident when they observe another person in need of help. If the
angle of depression to this other person is 42° and the helicopter is 18 feet
above the water, what is the horizontal distance from the rescuers to this
person to the nearest foot?
B
42° angle of depression
18 ft
42°
С
Round to the whole number
Answer=

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2

happy to

pls mark as brainliest

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:
