The expressions which represents the slope of a tangent to the curve
at any point (x, y) are:

<h3>The slope of a tangent to the curve.</h3>
Mathematically, the slope of a tangent line to the curve is given by this equation:

Given the function:

When (x + h), we have:

Next, we would find the derivative of f(x):

Using Pythagorean’s theorem
Side = 24 cm
Hence perimeter = 24+24+10+10
= 68 cm
Hence answer is 68cm




Option ( A ) is the correct answer.
Option B: 21.3 in is the length of AB
Explanation:
The equation is 
To find the length of AB, let us equate,

Substituting the value for sin 25°, we get,

Dividing the values, we have

Thus, the length of AB is 21.3 in.
The correct answer is Option B.
Answer: y= -2x/3 -3
Step-by-step explanation:
Substitute the x and y values from the given coordinate into the slope-intercept formula and solve for b
y = mx + b
-1 = -2/3(-3) + b
-1 = 2 + b
-1 -2 = b
-3 = b The y-intercept is -3
the equation: y = -2x/3 - 3
