X=number of weeks
We can suggest this inequation:
17x>175.5
x>175.5/17>10.323>11 (the solution have to be a whole number, therefore the answer will be 11 weeks or more)
Answer: Tomas need save money during 11 weeks.
Answer:
Step-by-step explanation:
<u>Since all graphs pass throught the origin, they all have the form of:</u>
- y = ax², where a- coefficient
The coefficient of each graph's equation can be calculated based on the given pairs of points.
Each of them calculated for you and attached below.
Here, The function: y = -x² + 4
Input values would be x coordinates & output values would be y.
When, x = 1, y = (-1)² + 4 = 1 + 4 = 5
x = 2, y = (-2)² + 4 = 4 + 4 = 8
x = 3, y = (-3)² + 4 = 9 + 4 = 13
In short, Your Three input values are: 1, 2, 3
Three Output values are: 5, 8, 13
Hope this helps!
I found h max = 64 feet
Explanation: Ok...probably you can do this differently but I would try to find the vertex of the parabola describing the trajectory: 1) derive it: h ` ( t ) = 64 − 32 t 2) set derivative equal to zero: 64 − 32 t = 0 t = 64 32 = 2 sec 3) use this value of t into your trajectory: h ( 2 ) = h max 64 ⋅ 2 − 16 ⋅ 4 = 64 feet .
