Answer:
f(x)=5x^2 + 9
Step-by-step explanation:
all numbers are odd
After solving
we get value of x: 
Step-by-step explanation:
We need to solve the equation
to find value of x
Solving

Adding -e on both sides


Multiply both sides by dx

Divide both sides by M-e

Divide both sides by d

So, After solving
we get value of x:

Answer:
77 feet below sea level.
Step-by-step explanation:
Since y is the time the submarine is ascending, we can plug it in for y and find our answer. We can create an equation where D is the depth and y is time ascending: D = -230 + 17y
Substitute 9 for y:
D = -230 + 17(9)
D = -230 + 153
D = -77
The depth of the submarine after 9 minutes will be 77 feet below sea level. Hope this helps, and Brainly will be highly appreciated.
For the law of sines, you would apply it in this particular problem like so:
Since P is 27, its angle is 33 and Q's length is 40; you would set it up like this
<u />40/SinQ = 27/Sin33, multiply 40 with Sin33, then it would be 40Sin33, then divide it by 27. The result should be 40Sin33/27 = X
