To find her heart rate per minute, set up a proportion.
Let x represent the number of heart beats in a minute.
12/5=x/60
5x=720
5/5x=720/5
X=144
Thus, her heart was beating at a rate of 144 beats per minute.

Given:
The function is
To find:
The derivative of the given function.
Solution:
Chain rule of differentiation:
Product rule of differentiation:
We have,
Differentiate with respect to x.
On further simplification, we get
Therefore, the derivative of the given function is .
Answer:
The radicand may not always be a perfect square. If a positive integer is not a perfect square, then its square root will be irrational. Consider 5–√ , we can obtain an approximation by bounding it using the perfect squares 4 and 9 as follows:

Yes. When the function f(x) = x3 − 75x + 250 is divided by x + 10, the remainder is zero. Therefore, x + 10 is a factor of f(x) = x3 − 75x + 250.
