✔8 Isn't a perfect square. Irrational numbers are numbers that cannot be represented as a ratio for example Pi, or non-perfect squares like ✔2, ✔3, ✔5, ✔8.
Answer:
Step 3, because the values for x for which y^1 < y^2 also include values between 3 and 5.
Step-by-step explanation:
Just took the test.
Answer:
y=-3x-3
Step-by-step explanation:
To get a perpendicular line you take the negative reciprocal of the slope, so in this case it would equal -3. Now use point-slope form to get your equation. Point slope form says that y-y1=m(x-x1) where m is your slope and x1 and y1 are the points that the graph passes through. So in this case x1=-3, y1=6, and m=-3. This gives you the equation y-6=-3(x+3). Distribute to y-6=-3x-9, and finally add 6 to both sides to get y=-3x-3
As for the domain, the only restriction comes from the logarithm. The argument of a logarith must be strictly positive, so we have
As for the range, we have:
- The range of
are all real numbers - If we change to
we're translating the function horizontally, so the range remains the same - If we change to
we're stretching the function horizontally, so the range doesn't change - If we change to
we're translating the function 1 unit up, but the range is already all the real numbers, so it doesn't change.
Notice the pattern of the out bags. For every person after the first, three more bags are pulled. By continuing this pattern you will eventually find the answer
1=2
2=5
3=8
4=11
5=14
6=17
7=20
8=23
9=26
10=29
11=32
Therefore, you need 11 people to get the job done in one day
