Answer:
I believe this is how you do it
Step-by-step explanation:
csc∅tan∅
(1/sin∅)(sin∅/cos∅)
(sin∅)/(sin∅cos∅)
1/(cos∅)
sec∅
csc²∅tan²∅sin∅
1/(sin²∅) * tan²∅ * sin∅
tan²∅/sin²∅ * sin∅
tan²∅/sin∅
X+x+2+x+x,+2=72
4x+4=72
4x=68
x=17. rectangle is 17 by 19
The total amount of little cubes on the surface is 600, since there is 100 cubes on one face and there are 6 faces (6 times 100). But, there is overlap because the cubes on the edges are painted on more than one edge. There are 12 edges, and every edge has 10 that need to be subtracted. So that’s a total of 120 that need subtracting, and 600-120 is 480.
For y=2x+125, the slope is 2, which means that the total will increase by 2, and the y-intercept is 125, and that is the starting value. So, y=2x+125 goes with the second choice on the right. For y=1/2x+125 means that 125 is still the starting value but instead of the total amount increasing by 2, it is divided by 2 and goes with the first choice on the right. For y=125x+2, the slope is 125 and 2 is the y-intercept, so the answer is the last one on the right.
