Answer:the slope is -14
Step-by-step explanation:
Area of one face =4/5 *4/5=16/25 (because the face is a square)
There are 6 such faces,
so the surface area = 6*(16/25)=96/25
if you need write that is a fraction 96/25,
if you need in decimal form,then 3.84
Answer:
B: y=cos(x) - 2
Step-by-step explanation:
You can use a graphing calc, write out a table, or use your knowledge. In this case, I will use my knowledge.
You can automatically rule out any answers with <em>sine </em>because the sin graph will never start at y=1 when x=0 (remember the unit circle and parent graphs), so rule out A. Since the graph shown is a transformation of only vertical from <em>y=cos(x)</em>, you can rule out C as well. Now you are left with B and D. B is the correct answer because if you chose D, the value for when x=0 would be y=0, while the value for x=0 for B would be y=-1, which is what you want.
If you would like to know which equation would cause a consistent-dependent system, you can find this using the following steps:
3x - 4y = 8 /*3
3 * 3x - 3 * 4y = 3 * 8
9x - 12y = 24
The correct result would be <span>9x - 12y = 24.</span>
