Step-by-step explanation:
Area of the octagon = 2(1+√2)8=309.02 units
Answer:
i think it is E
Step-by-step explanation:
The common ratio would be -2 since you multiply each number by -2 to get the next number in the sequence
The correct answer is 13.86.
In order to find this, we must first note that the tangent of any angle is equal to the opposite side length over the adjacent side length. If we use that formula and the 60 degree angle, we can find y.
Tan(angle) = Opp/Adj
Tan(60) = y/8
8Tan(60) = y
13.86 = y
Step-by-step explanation: So when graphing this problem, we start at -3 on our number line with an open dot because <em>k</em> is less than but not equal to -3. I have shown this in the image attached below.
We then draw an arrow going to the left to represent all number less than -3.
Finally, we put our answer in set notation which is shown below.
{K: k < -3}
All this means is that if we take any number less than -3, this will be a solution for the inequality <em>k < -3</em>.
