Answer:
2.5 m
Step-by-step explanation:
Consider the ramp, the ground and the back of the lorry to form a right triangle where the ramp is the hypotenuse and the distance from the back of the lorry is the adjacent side, x
Using the cosine ratio in the right triangle
cos32° = 
= 
Multiply both sides by 3
3 × cos32° = x, hence
x ≈2.5 m
Answer:
184 feet
Step-by-step explanation:
To answer this question you need to convert the 48 inches first to feet, as fabric is sold by the foot. 48 in converts to 4 ft which is what we will use for each curtain. Since we need 46 curtains we will multiply 46 curtains by 4 feet which will give our answer of 184 feet.
Answer:
<h2>on the positive y-axis</h2>
Step-by-step explanation:
Look at the picture.
(1) If x = 0, then the point is on the y-axis.
(2) If y > 0, then the point is above the x-axis.
From (1) and (2) we have: The point is on the positive y-axis.
