So, we have <span>xy=35
Since that, the first thing you should do is to </span><span>differentiate with respect to x
(look at the pic. 1), as you can see this is simply 1, which means you have to simplify
Then we need to perform solving for </span> for dy/dx as we are about to get <span>the derivative of y with respect to x. pic.2
Get back to the oroginal function, now we can substitute this for y to get the func which will depend only on x pic.3
Then pic.4
</span>
Given that
we first differentiate with respect to t to get the tangent vector, 
:
At t = 0, the tangent vector is
To get the <em>unit</em> tangent vector, multiply this by 1/(norm of tangent vector) :
Then the unit tangent vector is

Answer:
Area = 84 in²
Step-by-step explanation:
In order to find the area of the rectangle, you need to first set up an equation to find the length based on the information already given in the problem. Since the perimeter = 40 and the formula to find perimeter of a rectangle is: P = 2W + 2L, where W = width and L=Length, we can solve for 'L' by putting in the values given:
P = 2W + 2L or 40 = 2W + 2(3W - 4)
The length of the rectangle is '4 less than 3 times the width'. This can be written as the expression '3W - 4'.
Distribute: 40 = 2W + 2(3W - 4) or 40 = 2W + 6W - 8
Combine like terms: 40 = 8W - 8
Add '8' to both sides: 40 + 8 = 8W - 8 + 8 or 48 = 8W
Divide both sides by '8': 48/8 = 8W/8 or 6 = W
Solve for L: 3W - 4 or 3(6) - 4 = 18 - 4 = 14
Since L=14 and W = 6, we can solve for Area using the formula: A = LxW or A = (14)(16) = 84in².
Answer:
<em>The three angle bisector intersect at a point called the incenter</em> of the triangle, which is actually the center of the triangle. This center point is at equal distance from all sides of the triangle.
Also if a circle is inscribed in the triangle, the incenter will be located at the center of that circle.
