Find the first principle f(x)=1/x​

Mathematics
1 answer:
sveta [45]3 years ago
7 0

Answer:

see explanation

Step-by-step explanation:

Assuming you require the derivative of f(x) from first principles, then

f' (x) = lim_{h>0} \frac{f(x+h)-f(x)}{h}

       = lim_{h>0} \frac{\frac{1}{(x+h)}-\frac{1}{x}  }{h}

       = lim_{h>0} \frac{\frac{x-(x+h)}{x(x+h)} }{h}

       = lim_{h>0} \frac{\frac{x-x-h}{x(x+h)} }{h}

        = lim_{h>0} \frac{-h}{hx(x+h)} ← cancel h on numerator/ denominator

        =  - \frac{1}{x^2}

Determine if line AB is tangent to the circle. If so, then explain why.
zheka24 [161]

Answer:

Option A.

Step-by-step explanation:

we know that

If AB is tangent to the circle

then

The triangle show in the figure must be a right triangle

Remember that

If a triangle is a right triangle, then the triangle must satisfy the Pythagorean Theorem

<u><em>Verify</em></u>

Applying the Pythagorean Theorem

17^2=10.2^2+6.8^2

289=104.04+46.24

289=150.28 -----> is not true

so

Is not a right triangle

therefore

line AB is not tangent to the circle

The weights of boxes of candies produced in a factory are normally distributed with a mean weight of 16 oz and a standard deviat
JulijaS [17]
Let the required weight be X, then
z = (X - mean)/standard deviation
2 = (X - 16)/1
X - 16 = 2
X = 2 + 16
X = 18 oz.
