Answer:
Step-by-step explanation:
21x1/12=1.75 cm
1.75x10=17.55 mm
17.55 mm
Answer:
Step-by-step explanation:
B is correct: We Divide it (the coefficient b) by 2 and square the result.
Answer:
y=4x+7
Step-by-step explanation:
Line M is parallel to line L, so the equation for line M is y=4x+b
Plug in the coordinates of point (2,15), you get:
15=4*2+b
Solve that to get b=7
Therefore the equation of Line M is y=4x+7
Answer:
Step-by-step explanation:
Draw a picture.
θ = 81.7°
tanθ = height/121.6
height = 121.6tanθ ≅ 833.5
The building is 833.5 ft high.
:::::
When shadow is 2×121.6 = 243.2 ft long, tanθ = height/243.2
θ = arctan(height/243.2) ≅ 73.7°
