Derivative using direct definition of derivative 2-x/2+x

Daniel [21]

Let f(x) = (2 - x)/(2 + x). By definition of the derivative,

$\displaystyle f'(x)=\lim_{h\to0}\frac{f(x+h)-f(x)}h$

$\displaystyle f'(x)=\lim_{h\to0}\frac{\frac{2-(x+h)}{2+(x+h)}-\frac{2-x}{2+x}}h$

$\displaystyle f'(x)=\lim_{h\to0}\frac{\frac{(2-x-h)(2+x)-(2-x)(2+x+h)}{(2+x+h)(2+x)}}h$

$\displaystyle f'(x)=\lim_{h\to0}\frac{-4h}{h(2+x+h)(2+x)}$

$\displaystyle f'(x)=-4\lim_{h\to0}\frac1{(2+x+h)(2+x)}=\boxed{-\frac4{(2+x)^2}}$

A gold earring has a volume of 0.55cubic centimeters and a mass of 9.9grams. Calculate its density.

IgorC [24]

Answer:

.018 Kg/cm^3

Step-by-step explanation:

$p = m \div v \\$

Density (P) is equal to the mass (9.9g) divided by volume (.55cm^3)

$= 9.9 \div .55$

= 18g/cm^3

=.018kg/cm^3

Doughnuts at one shop cost £1.40 each.

eduard

Given parameters:

Cost of doughnut at one shop = £1.40

Unknown

Difference in the cost of doughnuts at the two shops = ?

To find the difference in the cost of doughnuts at the two shops, we must know the cost of doughnut at the second shop;

Given that the cost of doughnut at the other shop is 20% more;

= 1.20 x £1.4

= £1.68

The difference in the cost of doughnuts = £1.68 - £1.40 = £0.28

So the answer is £0.28
