Answer: I think you somehow managed to try to make an answer and then accidentally clicked "add a question" and then just so happened to not realize, so you made your answer as a question...
Step-by-step explanation:
Kidding, but I'm not sure what this is supposed to be answering... There is not much context given lol.
Answer:
About 2.569 seconds
Step-by-step explanation:
To solve this problem, you can separate it into two half parabolas. The beginning part is initial upward rising. To calculate the amount of time that this part of the dive takes, you can use the formula
, where
is the final velocity,
is the initial velocity, a is the acceleration due to gravity, and t is the amount of time it takes. You know that the final velocity is 0, since the diver is reaching the terminal of their dive. Therefore, you can set up the following equation (assuming that the acceleration due to gravity is 32ft/s^2):

seconds
To find the height that this indicates the diver has risen, you can plug this time into the following formula: 
feet
For the second part, you can use the equation
again. Since the initial velocity for this part is 0, you can set up the following equation:


Adding this to the time that the first part of the dive takes, you get a total of about 2.569 seconds. Hope this helps!
The answer should be
4.
First, simplify

to 4. Your problem should look like: 4 x 1.
Second, multiply. 4 x 1 = 4 so that is your answer.
Also, to start the equation up, make sure to add in the numbers in replace for the letters. Your problem to start with should look like:

.
Answer:
887 and 792 km per hour
Step-by-step explanation:
Lets call the first plane A and the second B
we know that: a=b+95
We can say that 3358=2b+(2b+190)<=A
When solved, we get 3168=4b
b=792 km per hour.
Go back to step two. A=b+95, so A=792+95=887 km per hour
The two planes rates are 887 km per hour and 792 km per hour.
