Answer:
Y=-4x+90
Step-by-step explanation:
Slope Intersect Form → Y=mx+b
M= (y2-y1)/(x2-x1)
Find two point of the graph, I choose (0,90) and (10,50)
Plug in back the formula,
(90-50)/(0-10)
=40/-10
=-4
To find B (Y intercept), it is where the graph intersect the y axis
In this case, it is 90.
Thus, Y=-4x+90
The zeros of function are x-s, for which f(x) = 0:
Applying the sine ratio and law of sines, the correct measurements are:
B. m∠B = 15°
E. h ≈ 31.28 ft.
<h3>What is the Sine Ratio?</h3>
Sine ratio that can be used to determine the side length of a right triangle is, sin ∅ = opposite side/hypotenuse.
Find c using the law of sines:
C = 33°
A = 180 - 48 = 132 [linear pair]
B = 180 - 33 - 132 = 15° [triangle sum theorem]
b = 20 ft
c = ?
Using the law of sines, b/sin B = c/sin C, we have:
20/sin 15 = c/sin 33
(c)(sin 15) = (20)(sin 33)
c = (20 × sin 33)/sin 15
c ≈ 42.09
Use the sine ratio to find h:
∅ = 48°
Hypotenuse = c = 42.09
Opposite = h = ?
sin 48 = h/42.09
h = (sin 48)(42.09)
h ≈ 31.28
The correct measurements are:
B. m∠B = 15°
E. h ≈ 31.28 ft
