Answer:

330 cm ^

Step-by-step explanation:

split it into 4 sections:

two base triangles 2((6*8)/2)

rectangle from leg 1 (8*13)

rectangle from leg 2 (6*8)

add all the individual areas together

24+24+130+104+48=330

Hope this helps :)

Describe the following variation: y/x2=5

Firdavs [7]

We are asked to describe the variation $\displaystyle{ \frac{y}{x^2}=5$ ,

that is $y=5x^2$

for x≠0, in which case x=y=0, we distinguish the following intervals:

I = (-infinity, -1]
II = (-1, 0)
III = (0, 1)
III = [1, infinity)

Case I, consider the cases (examples) x= -5, and x= -6

$5(-6)^2\ \textgreater \ 5(-5)^2$ , so we can conclude that the greater the x, the smaller the y.

Case II, consider x= -1/2 < x=-1/3

$5(-\frac{1}{2})^2= \frac{5}{4}\\\\ 5(-\frac{1}{3})^2= \frac{5}{9}\\\\\frac{5}{9}\ \textless \ \frac{5}{4}$

thus, the greater the x, the smaller the y.

Case III, consider the cases (examples) x= 5, and x= 6

$5(6)^2\ \textgreater \ 5(5)^2$ , so we can conclude that the greater the x, the greater the y.

Case III, consider x= 1/3 < x=1/2

$5(\frac{1}{2})^2= \frac{5}{4}\\\\ 5(\frac{1}{3})^2= \frac{5}{9}\\\\\frac{5}{9}\ \textless \ \frac{5}{4}$

thus, the greater the x, the greater the y.

Conclusion:

y=0 only if x is 0. Otherwise y>0 always:

for x<0, x and y are inversely proportional

for x>0, x and y are directly proportional.

Remark, an other possible consideration in cases could be x<0 and x>0 only.

Remark, another approach is considering the graph of y=5x^2, which is a parabola, with the vertex at (0, 0) opening upwards.

From the graph we can find the same conclusion. That is we can see that the farer we get away from the y-axis, in both direction, the larger the values of y become.

A shopkeeper sold 12 bags on the first day. The number became four times

dybincka [34]

The total number of the bags sold by the shopkeeper will be 65532.

<h3>What is number series?</h3>

The sequence formed by using the numbers is termed as the number series.So in this question from day one to day seven each day the sold items are multiplied by 4.

So the mathematical expression will be given as:

$=(12\times 4^0)+(12\times 4^1)+(12\times 4^2)+(12\times 4^3)+(12\times 4^4)+(12\times 4^5)+(12\times 4^6)$
