There is a video on khanacademy, search "rationalize the denominator." Then instead of getting the answer you will learn how to do it and be able to do it on other problems in the future.
It would be 6824 because 6825 would be 6830 and 6824 is the largest number that rounds down to 6820
Answer:
True
Step-by-step explanation:
That expression is called the "Quadratic formula" and basically the solution to any second degree equation can be find by using the quadratic formula.
Attached you can find the procedure to get to the quadratic formula from the general equation of a second degree polynomial.
Answer:
⇒y=32x+18
Step-by-step explanation:
The <u>correct answer</u> is:
As x→-∞, y→-3.
As x→∞, y→∞.
Explanation:
As our values of x get further into the negative numbers, the value of 2ˣ will approach 0. This is because raising a number to a negative exponent "flips" the number below the denominator and raises it to a power; we end up with smaller and smaller fractions, eventually so small that they nearly equal 0.
This will make the value of the function 0-3=-3.
As x gets larger and larger (towards ∞), the value of y, 2ˣ, continues to grow as well. Since it continues to grow exponentially, we say the value approaches ∞.
