Answer:
When number of bricks is multiplied by 2, the length is multiplied by
B) 2
Step-by-step explanation:
Number of bricks is two times the length of the wall
i.e. Number of bricks= 2×Length of the wall
When the number of bricks is multiplied by 2, the length is also multiplied by 2
since, when number of bricks=6 then, length of wall=3
and when number of bricks=2×6=12 then, length of wall=2×3=6
Hence, when number of bricks is multiplied by 2, the length is multiplied by
B) 2
<u>Answer:</u>

<u>Step-by-step explanation:</u>
We are given that the measure of angle θ is 600° and we are to fin the point (x, y) corresponding to angle θ on the unit circle,
We know that the x,y coordinates in the unit circle are the cosine and sine ratios, respectively.
θ = 600
1 unit circle= 360°
It means that 600° corresponds to 600° - 360° = 240°.
So, θ = 360° + 240°
180° < 240° < 270° (this tells that the point is in the third quadrant and its coordinates are negative)
240° - 180° = 60° (using the supplementary angles to find the sin and cos)
Therefore, the x-coordinate is the cos of the given angle while y-coordinate is the sine of the given angle and the coordinates are:
