Answer:B cos 29°, sin 61° since,cos(x)=sin(90°-x) or sin(x)=cos(90°-x)
Hello there!
<span>A graph is shown below: Dotted line joining negative 1, negative 2 and 5,0 and the region above the line is shaded. Which of the following inequalities is best represented by this graph? x − 3y > 5 x − 3y < 5 x − 2y > 5 x − 2y < 5
Answer:
</span><span>x – 3y < 5</span>
Number of swings = x
Number of slides = y
First condition:
number of slides must be more than 3 times number of swings
This means that: y > 3x
Second condition:
each swing cost 275$ and each slide costs 168$. They cannot spend more than 1250$. This means that the sum of costs of swings and slides should not exceed 1250$ (should be less than or equal to 1250$)
This means that: <span>275x+168y ≤ 1250
Based on this:
The correct choices are: b and d</span>
