Answer:
The standard form of the equation of the parabola is (y + 2)² = 8 (x - 3)
Step-by-step explanation:
The standard form of the equation of a parabola is (y - k)² = 4p (x - h), where
- The vertex of the parabola is (h , k)
- The focus is (h + p, k)
∵ The vertex of the parabola is (3 , -2)
∴ h = 3 and k = -2
∵ The focus is (5 , -2)
∴ h + p = 5
- Substitute h by 3 to find p
∵ 3 + p = 5
- Subtract 3 from both sides
∴ p = 2
∵ The standard form of the equation of the parabola is (y - k)² = 4p (x - h)
- Substitute the values of h , k , and p in the equation
∴ (y - -2)² = 4(2) (x - 3)
∴ (y + 2)² = 8 (x - 3)
The standard form of the equation of the parabola is (y + 2)² = 8 (x - 3)
Looks like it should be D since they spent 0.08 on tickets and get 1.92. Then shirts are $55 so we subtract this from the profit.
The correct answer is the third one.
However, i would suggest you to remember the following simple rule:
Uhh... is this the full problem because this looks like this is half a problem.
Jose will spend 18 minutes on his science homework.
Step-by-step explanation:
Given,
Time Jose have to spend on homework = 5/6 hour
We know that 1 hour = 60 minutes
Therefore;
Time Jose have to spend on homework = 50 minutes
Time spent on math home work =
Time spent on math home work =
Rounding off to nearest whole minute;
Time spent on math homework = 17 minutes
Time spent on reading homework = 15 minutes
Total time spent = Mathematics + Reading + Science
50 = 17+15+Science
50 = 32 + Science
Science = 50-32 = 18 minutes
Jose will spend 18 minutes on his science homework.
