Answer:
2-[1, 2]
Step-by-step explanation:
From the graph, we can conclude the following things:
1. The graph is of degree 4 as it intersects the x axis at 4 points.
2. The graph tends to infinity for increasing the value of 'x' along positive or negative x-axis.
3. The graph has 3 turning points between the intervals [-1, 0], [1, 2] and [2, 3]
4. Local maximum: The top of mountain of the graph represents local maximum. So, during the interval [1, 2], there is a local maximum.
5. Local minimum: The lowest point or the valley of the graph represents local minimum.
So, during the intervals [-1, 0] and [2, 3], there are local minimums.
Thus, there is only one local maximum during the interval [1, 2].
The number of passengers that :
- Needs Transfer only = 13 passengers
- Are going to work only = 17 passengers
Let :
Passengers that needs transfer = T = 35
Passengers going to work, W = 39
Passengers who do not need transfers and aren't going to work = 12
Using a venn diagram :
Let the Passengers who do not need transfers and are going to work and needs transfer = x
Passengers who need transfer only = 35 - x
Passengers who are going to work only = 39 - x
To find x :
35 - x + 39 - x + x + 12 = 64
86 - x = 64
-x = 64 - 86
-x = - 22
x = 22
the number of passengers that need transfers but aren’t going to work will be = 35 - 22 = 13 passengers
the number of passengers that are going to work but do not need transfers will be : 39 - 22 = 17 passengers

Answer:
3
Step-by-step explanation:
step1 Isolate the square root on the left hand side
Original equation
√2x-5-4 = -x
Isolate
√2x-5 = 4-x
step2 eliminate the radical on the left hand side
Raise both sides to the second power
(√2x-5)2 = (4-x)2
After squaring
2x-5 = x2-8x+16
step3 Solve the quadratic equation
Rearranged equation
x2 - 10x + 21 = 0
This equation has two rational roots:
{x1, x2}={7, 3}
step4 Check that the first solution is correct
Original equation, root isolated
√2x-5 = 4-x
Plug in 7 for x
√2•(7)-5 = 4-(7)
Simplify
√9 = -3
Solution does not check
3 ≠ -3
step5 Check that the second solution is correct
Original equation, root isolated
√2x-5 = 4-x
Plug in 3 for x
√2•(3)-5 = 4-(3)
Simplify
√1 = 1
Solution checks !!
Solution is:
x = 3
Answer:
19 days
Step-by-step explanation:
2 weeks = 14 days
14 + 5 = 19
(answer)increases, 22
(explanation)the numbers show that they increase going from 22 to 44 to 66. subtract 22 from either number (44 or 66) and youll get 22. add 22 to each number (44 and 66) and youll get the numbers 44 and 66, meaning the mouses travel increases by 22 feet.
