She drove 9 miles over the speed limit.
94.50 + 2m = 112.50
Subtract 94.50 from both sides
2m = 18
Divide both sides by 2
m = 9
Answer:
The 72 feet is measured on the slope, not out from the pole horizontally. I get
top of pole is at
40 + 72 sin17°
downhill point is
72 cos 17°
from point beneath the pole
cable^2 = (40+72 sin17°)^2 + (72 cos 17°)^2
Answer:
608 ÷ 19 = 32
Step-by-step explanation:
608 ÷ 19 = 32
Hope this helps! :)
Arcsecant or arcsec or sec⁻¹ is an inverse trigonometric function. And many calculators don't have a key for them because they can be calculated with basic trigonometric functions like so:
sec⁻¹(x)=cos⁻¹(1/x).
So the correct answer is the fourth one: y=cos⁻¹(1/x).
3x^2 + 6x - 2 = 0
discriminant = b^2 - 4ac; where a = 3, b = 6 and c = -2
d = 6^2 - 4(3)(-2)
d = 36 + 24
d = 60
