Answer:
=64 ft
Step-by-step explanation:
The wire, the pole and the flat surface form a right triangle with a base angle of 40°. The pole is the height of the triangle and is opposite the angle 40°.
Therefore we can use the trigonometric ratio -sine of the angle 40° -to find the height.
Sin∅ =opposite/hypotenuse
opposite=hypotenuse × sin∅
=100ft × Sin 40°
=64.28ft
≅64 ft
Answer:
Third option <3, 9>
Step-by-step explanation:
u and v are two vectors and we know the Cartesian components of these vectors.
We must find the sum of u + v.
If we have the Cartesian components of both vectors then the sum of both is done by adding the components of u with the components of v.
Where i is the vertical component and j is the horizontal component
Then u + v is

Answer:

Step-by-step explanation:
A rocket is launched from a tower. The height of the rocket, y in feet, is related to the time after launch, x in seconds, by the given equation. Using this equation, find the time that the rocket will hit the ground, to the nearest 100th of second.
y=-16x^2+129x+119
y=−16x
2
+129x+119
Subtract x from both sides
divide by -1
