It's a similar triangle so the ratios of corresponding sides should be equal which means

BC/EF = AB/DE
21/14 = AB/10
AB = 21/14 * 10 = 15 cm

kicyunya [14]

Answer:

7 people
53 coins

Step-by-step explanation:

The problem statement tells us ...

8x = y +3

7x = y -4

Subtracting the second equation from the first gives ...

x = 7

Then ...

y = 7x +4 = 7·7 +4 = 53

There are 7 people, and 53 coins are required for purchase.

Help me find the area of this circle

ch4aika [34]

The area would be approximately 153.94.

The area of a circle is pie multiplied by r^2.

So you have the radius, which is r. Plug in r. Technically you have two numbers because pie equals approximately 3.14.

Finding the inverse function for f(x)=1/x^2

Anna [14]

to get the inverse of any expression, we start off by doing a quick switcheroo on the variables and then solve for "y".

$\stackrel{f(x)}{y}=\cfrac{1}{x^2}\implies \stackrel{\textit{quick switcheroo}}{x=\cfrac{1}{y^2}}\implies y^2=\cfrac{1}{x}\implies y=\sqrt{\cfrac{1}{x}}\implies \stackrel{f^{-1}(x)}{y}=\cfrac{1}{\sqrt{x}}$
