Stationary points occur where the derivative is zero. The denominator is positive for all
, so we only need to worry about the numerator.
for all
, so we can divide through:
But
for all
, so this function has no stationary points...
I suspect there may be a typo in the question.
she bought 10 pencils and 5 erasers
Let x represent the number of pencils and y represent the number of erasers.
Gabby wants to spend exactly $2.00 on pencils and erasers, hence:
0.15x - 0.1y = 2 (1)
Therefore x = 10 and y = 5
Therefore she bought 10 pencils and 5 erasers.

Answer:
∂u/∂xi = i·cos(sn)
Step-by-step explanation:
For u = sin(v), the partial derivative of u with respect to xi is ...
∂u/∂xi = cos(v)·∂v/xi
In this case, v=sn, and ∂sn/∂xi = i, so the derivatives of interest are ...
∂u/∂xi = i·cos(sn)
Step-by-step explanation:
Given
Slope (m) = 4
Point ( -1 , 5)
Now the equation of line is
y - y1 = m ( x - x1)
y - 5 = 4 ( x + 1)
y - 5 = 4x + 4
4x + 4 - y + 5= 0
4x - y + 9 = 0
which is the required equation
The answer is c y=3x-1 if you just plug in the numbers you can see if it is equal
