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!
Answer:
Please see the matches between the equations provided with the data set below.
Step-by-step explanation:
A. y = 10x + 65
It matches with the data set located at the bottom right, where x represents the number of hours studied, and y represents the grade on test.
B. y = 2x - 1
It matches with the data set located at the top right, where we have:
x y
1 1
1.5 2
2 3
2.5 4
3 5
C. y = x + 2
It matches with the data set located at the bottom left, where:
x y
2 4
5 7
10 12
D. y = x - 0.50
It matches with the data set located at the top left, where:
x y
1 0.50
1.50 1
2 1.50
2.50 2
3 2.50

Answer:
85.33ft2
Step-by-step explanation:
Answer:
x=-45
Step-by-step explanation:
-x/3=15
-x=15×3
=45
Hence, x=-45.
Ok, so this is a spelling sort of work sheet, you need to say each word aloud and if the A in the word is long, then put it in the long A box, if it's a short sounding A, then put it in the short A box.
Hope this helps >.<
