Answer:
Step-by-step explanation:
7.
roots=-2,-1,1,3
critical points=(-1.5,-3),(0,6),(2,-13)
absolute minimum=-13
End behavior :approaches +infinity
Relative max=6 at (0,6)
Relative min. =-3 at (-1.5,-3)
and -13 at (2,-13)
interval of increase=(-1.5,0)∪(2,∞)
interval of decrease=(-∞,-1.5)∪(0,4)
8.
roots=-1,2
critical points=(0.5,10.5),(4,-10.5)
Abs.max/abs.min=not defined
End behavior:-∞ to +∞
Relative max=10.5
Relative min=-10.5
interval of increase=(-∞,0.5) ∪ (4,∞)
interval of decrease=(0.5,4)
The LCM is the lowest number that is a multiple of all three numbers.
First, list the multiples of each number
8: 8, 16, 24, 32,40 48, 56, 64, 72, 80, 88, 96, 104, 112, 120
10: 10, 20, 30 40, 50, 60, 70, 80, 90, 100, 110, 120
12: 12, 24, 36, 48, 60, 72, 84, 96, 108, 120
The LCM is 120 because there is no lower number that is a multiple of all three numbers.
Hope this helped!
If Liza takes 120 steps, then the number of steps taken by Pete will be 72.
<h3>What are a ratio and a proportion?</h3>
A ratio is an ordered set of integers a and b expressed as a/b, with b never equaling 0. A percentage is a mathematical expression in which two things are equal.
Pete, Lulu, and Liza are walking in the Boston downtown. Each time Pete takes 4 steps, Lulu takes 3 steps. Each time Lulu takes 5 steps, Liza takes 4 steps.
Then the relation between is given as
4 Pete → 4 Lulu
5 Lulu → 4 Liza
Then we have
If Liza takes 120 steps, then the number of the step taken by Pete will be
