Answer:
11.5cm
Step-by-step explanation:
1.2 meters = 120 centimeters
(for the 9 of them, with each being 9.5cm) = 9 * 9.5
=85.5cm
(For The rest of the remaining 3 books): 120cm - 85.5cm
=34.5cm
Each of them would be 34.5 / 3
=11.5cm
Answer:
f(x)=2x2−8x+4. Explanation: the equation of a parabola in vertex form is.
We are looking for the approximate solution of

, that is, we are looking for the solution of the equation f(x)=g(x).
The solution of this equation are represented by the intersecting points (x, y) of the graphs of these functions, because the intersecting points (x, y) are such that
y=f(x), but also y=g(x).
From the graph, we can see that there are two solutions, one is at approximately x=2, and the other is approximately -1.4.
Answer: -1.4, 2.
Answer:
C
Step-by-step explanation:
If you add all of the numbers together, that is the denominator, 70. The amount of purple is 17, the numerator.
In order to sole the problem you need to create an equation to model what you are trying to do.
You end up with an equation looking like
25000*0.95^t
25000 is the starting value when t=0
95% is the amount remaining after the 5% decay
0.95 is being raised to the power of t to determine how many times it has decayed
When t=3 the equation should be
25000*0.95^3=21434.375
