Answer:
A. x=0 and x=4
Step-by-step explanation:
The roots of a quadratic function are the x intercepts of the parabola. In this case, the roots are 0 and 4 because the parabola intercepts the x axis twice in these points.
Your answer is A. x=0 and x=4
Hope I helped!
It is also the same as 8 to the power of 7
which looks something like this 8^7
you can also do it by doing 64×64×64×8
then do 64×64
multiply that answer by 64
multiply that answer by 8
this will work with any question and you can do it without a calculator and on paper.
Answer:
i dont understand
Step-by-step explanation:
If you increased 5 to 10, then I would have doubled the number 5 and this is a 100% increases.
If you increased 5 to 7.5, then this is 50% increase, because 50% of 5 is 2.5 and 5 + 2.5 = 7.5
If you increased 5 to 6, then this is a 20% increase,because 5 + 1 = 6 and 1 is 20% of 5
If you increased 5 to 7, then this is a 40% increase,because 5 increased by 2, 5 + 2 = 7, and 2/5 = 40%
If you increased 5 to x, then 5 was increased by x/5×100%
For example 5 to 9 is a4/5×100%=80% increase
So here 5 increases by 8, 5 + 3 = 8, thus the percentage increase is3/5×100%=0.006
