For the first question, simply plug in the value of 3 into the polynomial question. The final answer is your volume of the hot water tub.
For the second question, you can figure out that x = -5 is not a real root because it does not touch or cross the x axis.
If it does it would be an solution.
Answer:
cos(C)
Step-by-step explanation:
Recall that the sine ratio is opposite over hypotenuse.

Also the cosine ratio is adjacent over hypotenuse.

The tangent ratio does not come close because it doesn't involve the Hypotenuse.

Answer is B
Explanation:
Divide -3/4 which equals -0.75
Then divide 5/8 which equals 0.625
Now look at the answers and divide the ones that are in fractions to get a decimal
The answer is B because -1/2 = -0.5 and that is greater than -0.75 and less than 0.625
Sounds confusing sorry
