Answer:
-
Step-by-step explanation:
A root with square root or under root is only obtained when we take the square root of both sides. Remember that when we take a square root, there are two possible answers:
- One answer with positive square root
- One answer with negative square root
For example, for the equation:

If we take the square root of both sides, the answers will be:

Only getting one solution with square root is not possible. Solutions with square root always occur in pairs.
For given case, the roots are 6 and
. Therefore, the 3rd root of the polynomial function f(x) had to be -
It seems you made error while writing option B, it should be - square root of 5.
The answer is 2.22 if you divide it. Add the ingredients then divide on how many servings.
It would be the one with the number that is furthest away from 0 either negative or positive. in this case it would be A
Answer:
From inspection of the diagram, we can see that the spinner is divided into <u>4 equal parts</u>, where 3 parts are red and 1 part is yellow.

Therefore,


<u>Multiplication Rule for Independent Events</u>
For independent events A and B:
Therefore,

<h3><u>Conclusion</u></h3>
Ari is incorrect. The spinner is divided into 4 parts, where only one part is yellow. Therefore, the probability of spinning a yellow is 1/4. As the events are independent, the Multiplication Rule should be used to calculate the probability of spinning 2 yellows. So the probability of spinning 2 yellows is 1/4 x 1/4 = 1/16.
*assume the pool is empty at the beginning
a) plug 3.25 into the equation and solve
h(3.25) = 600*3.25 = 1950 gallons
b) after 3.25 hours the total amount of water will be 1950 gallons
