Answer: 
Step-by-step explanation:
Given :
re - writing the equation , we have
we need to find the value of a and b for which -2<x < 4 , this means that the roots of the quadratic equation are -2<x < 4.
The formula for finding the quadratic equation when the roots are known is :
- sum of roots(x) + product of root = 0
sum of roots = -2 + 4 = 2
product of roots = -2 x 4 = -8
substituting into the formula , we have:
, which could be written in inequality form as
comparing with , it means that :
2/3(x-7)=-2
2/3x-14/3=-2
2/3x=-2+14/3
2/3x=-6/3+14/3
2/3x=8/3
3/2(2/3x)=8/3(3/2)
6/6x=24/6
x=4
Answer:
1, 2, 3, 9

They are all factors of 18 and 27.
Answer:
3.25 seconds.
Step-by-step explanation:
We can use the formula <em>Final Velocity = Initial Velocity + Acceleration * Time </em> to solve this problem.
First, we plug in the values we already know, and then we solve like normal:
1.5 = 0.2 + 0.4*t
1.3 = 0.4 * t
3.25 = t
Therefore, the mosquito accelerated for 3.25 seconds.
