-15 + 7 is the addiction expression
Answer:
The camera had to cover the greatest angle is CAMERA 3 because it had the largest angle of 71.47°
Step-by-step explanation:
From the above question,
We have:
Camera 1 = Angle A
Camera 2= Angle B
Camera 3 = Angle C
A = 210ft
B = 234ft
C = 260ft
We need to find Angle A( angle of camera 1) using the cosine rule
A=(B² + C² - 2BCCosA)
210² = 234² + 260² - 2 × 234 × 260 × CosA
210² = 122356 - 121680CosA
Square both sides
210² = 122356 - 121680CosA
44100 = 122356 - 121680CosA
121680CosA = 122356 - 44100
121680CosA = 78256
Cos A = 78256/121680
Cos A = 0.6431295201
A = arc cos (0.6431295201)
A = 49.974422249°
Angle A approximately = 49.97°
Using the Sine rule to find the Angle B
A/Sine A = B/Sine B
210ft/Sine 49.97° = 234ft/Sine B
210ft × Sine B = 49.97° × 234ft
Sine B =( Sine 49.97° × 234ft)/210ft
B = arc sin (0.8532172354)
Angle B = 58.56334
Approximately = 58.56°
Angle C = 180 - (49.97 + 58.56)°
Angle C = 71.47°
Therefore, the camera had to cover the greatest angle is Camera 3 because it had the largest angle of 71.47°
The range of sinx is [-1; 1]
The range of 3sinx is [-3; 3]
The range of 3sinx + 3 is [0; 6]
Answer: y ∈ [0; 6]
24.8 cm ÷ 175= 0.141... or 0.14 cm.
The answer is 0.14 cm.
Hope this helps
Equation of a line that passses through (x1,y1) and has a slope of m is
y-y1=m(x-x1)
perpendicular lines have slopes that mulitply to get -1
given
y-2=7/3(x+5)
slope is 7/3
perpendicular
7/3 times slope=-1
times 3/7 both sides
slope=-3/7
given point is (-5,2)
y-2=-3/7(x-(-5))
y-2=-3/7(x+5)
