Answer:
205 litres
Step-by-step explanation:
The expression that gives the volume of water in Eduardo's pool (in liters) is:
![100 + 20m](https://tex.z-dn.net/?f=100%20%2B%2020m)
where m is time, in minutes
After
minutes (
minutes), the volume is will be:
![100 + (20 * \frac{21}{4} )\\\\\\100 + (5 * 21)\\\\\\100 + 105](https://tex.z-dn.net/?f=100%20%2B%20%2820%20%2A%20%5Cfrac%7B21%7D%7B4%7D%20%29%5C%5C%5C%5C%5C%5C100%20%2B%20%285%20%2A%2021%29%5C%5C%5C%5C%5C%5C100%20%2B%20105)
= 205 litres
The volume of water in the poll will be 205 litres.
Answer:
it =64
Step-by-step explanation:
4x4x4
Y= (x-2)² + 5. We can write it as : y-5 = (x-2)². The general equation of a quadratic function is :
(y-k) = a(x-h)², where h and k are the vertex of the parabola and a, the coefficient which determines whether the parabola opens upward or downward.
So, y-5 = (x-2)²
Having said that we can say that the VERTEX( 2,5) and since a=1 (a>0) the parabola is open upward OR it passes by a MINIMUM (Then the vertex is minimum)
The domain (x- value) is all Real { x|x = -∞ to x=+∞}
The Range (y-value) is all y ≥ 5
