Give each answer as mixed number in simplest form

telo118 [61]

Step-by-step explanation:

$= \frac{1}{2} + ( - 5 \frac{9}{10} )$

$= \frac{1}{2} - 5 \frac{9}{10} \\$

$= \frac{1}{2} - \frac{5 \times 10 + 9}{10} \\$

$= \frac{1}{2} - \frac{59}{10} \\$

$= \frac{1}{2} \times \frac{5}{5} - \frac{59}{10} \\$

$= \frac{5}{10} - \frac{59}{10} \\$

$= \frac{5 - 59}{10} \\$

$= - \frac{54}{10} \\$

$= - \frac{27}{5} \\$

suppose you have 76 feet of fencing to enclose a rectangular dog pen. The function A=38x-x^2, where x= width, gives you the area

yan [13]

If A=38x-x^2 then

dA/dx=38-2x

d2A/dx2=-2

Since the acceleration, d2A/dx2 is a constant negative, when velocity, dA/dx=0, it will be an absolute maximum for A(x)

dA/dx=0 only when 38=2x, x=19

A(19)=38(19)-19^2

A(19)=722-361

A(19)=361 ft^2

So the maximum possible area is 361 ft^2

(This will always be true as the maximum possible area enclosed by a given amount of material will always be a perfect square...)

For this case we have the following arithmetic sequence:

$a_ {n} = 15 + 5 (n-1)$
