Write and expression that represents the difference of 32 and n , multiplied by 10
natali 33 [55]

Answer:

10(32 - n)

Step-by-step explanation:

This is a beginning algebra question. It is trying to find out if you know what a difference is.

A difference always means subtract in math. Always. There are no exceptions.

So the difference between 32 and n is 32 - n

This difference is multiplied by 10

10(32 - n)

Usually the number mentioned first is the number put to the left of the subtract sign.

If you tell me the answer is 10(n - 32) then you should say that it is the difference between n and 32.

Lim t^4 - 6 / 2t^2 - 3t + 7
Harman [31]

I think you meant to say

\displaystyle \lim_{t\to2}\frac{t^4-6}{2t^2-3t+7}

(as opposed to <em>x</em> approaching 2)

Since both the numerator and denominator are continuous at <em>t</em> = 2, the limit of the ratio is equal to a ratio of limits. In other words, the limit operator distributes over the quotient:

\displaystyle \lim_{t\to2} \frac{t^4 - 6}{2t^2 - 3t + 7} = \frac{\displaystyle \lim_{t\to2}(t^4-6)}{\displaystyle \lim_{t\to2}(2t^2-3t+7)}

Because these expressions are continuous at <em>t</em> = 2, we can compute the limits by evaluating the limands directly at 2:

\displaystyle \lim_{t\to2} \frac{t^4 - 6}{2t^2 - 3t + 7} = \frac{\displaystyle \lim_{t\to2}(t^4-6)}{\displaystyle \lim_{t\to2}(2t^2-3t+7)} = \frac{2^4-6}{2\cdot2^2-3\cdot2+7} = \boxed{\frac{10}9}
