Based on the graph, all x values are possible so the answer is C.
It would be 10:15, which can be simplified to 2:3 if you divide by 5. Hope this helps!
Answer:
0.18 sec or 3.4 sec.
For second part, it will take 3.7 sec.
First part:
Set h(t) = 17and solve for t.
-16t²+ 58t + 7= 17
-16t² + 58t - 10 = 0
Solve this quadratic equation for t. You should get 2 positive solutions. The lower value is the time to reach 17 on the way up, and the higher value is the time to reach 17 again, on the way down.
Second part:
Set h(t) = 0 and solve the resulting quadratic equation for t. You should get a negative solution (which you can discard), and a positive solution. The latter is your answer.

Answer:
26, 37, 40, 48
Step-by-step explanation:
Whole numbers between 20 and 50 will have 10s digits in the range 2–5.
When 4 is added to these numbers, we get ...
2+4 = 6
3+4 = 7
4+4 = 8
5+4 = 9
When 4 is subtracted from these numbers, we get ...
2-4 = -2
3 -4 = -1
4 -4 = 0
5 -4 = 1
__
The numbers we can make using the given 10s digits and their corresponding 1s digit(s) are ...
26, 37, 40, 48
__
We note that any number with a 10s digit of 5 and a 1s digit other than 0 will be out of range.
For 1 pastry he can make 9 combinations
So your answer is 6 * 9 = 54 combinations.
