Answer:
slope of the given straight line in graph is -2
Step-by-step explanation:
<u>Explanation:</u>-
in given graph we have to choose points are A(0,3) on y-axis and B(1.5 , 0) on x- axis
let m be the slope of a line
by using slope formula is
m =
m= -2
<u>another points we have choose</u>
in given graph we have to choose points are A(0,3) on y-axis and B(2.5 , -2)
<u>slope of a line</u> :-
let m be the slope of a line
by using slope formula is
m= -2
where ever you will take point the slope of given straight line is
m = -2

Answer:
The angle of elevation of the plane measured from Ahmed is approximately 36.67°
Step-by-step explanation:
The given parameters of the float plane are;
The height of the float plane above the water, y = 350 m
The horizontal distance of the float plane from Ahmed, x = 470 m
Given that Ahmed is sitting on the dock, by the water, by trigonometric ratios, we have;
The height of the float plane, the distance of the plane from Ahmed and the line of sight forming the angle of elevation of the plane measured from Ahmed, form a right triangle
Therefore
Where;
θ = The angle of elevation of the plane measured from Ahmed
y = The leg of the right triangle opposite the reference angle
x = The leg of the right adjacent to reference angle
Therefore;
θ = arctan(y/x) which gives;
θ = arctan(350/470) ≈ 36.67°
The angle of elevation of the plane measured from Ahmed, θ ≈ 36.67°.
