/ means division
So C would be the correct answer
Answer:
Given : length of FG = 4.3 ft
angle GFH = 52°
so we know cos theta = Base/ Hypotenuse
and here cos52° = x / 4.3
=> 0.61566147532 = x/4.3 [ as cos52° = 0.6156614]
=> 2.6445 = x
So the value of x = 2.6445 ~ <em>2.7</em> ft(ans)
Hope it helps
In order to be differentiable everywhere, must first be continuous everywhere, which means the limits from either side as must be the same and equal to . By definition, , and
so we need to have .
For to be differentiable at , the derivative needs to be continuous at , i.e.
We then need to have
Then
Hello Carousel!
To start solving this question, note that ⇨ for any 2 differentiable functions, the derivative of the quotient of the 2 functions will be the denominator multiplied by the derivative of the numerator minus the numerator again multiplied by the derivative of the denominator whole divided by the denominator². By doing all these steps, we'll get it as..
Remember that the derivative of the polynomial will be the sum of the derivatives of its terms. We know that, the derivative of a constant term is 0 & the derivative of is . So..
Now, simplify it..
- You can further simplify the answer to
