Simora [160]

Answer:

$1+r+r^{2}+r^{3}+.....+r^{n-1} = \frac{1-r^{n}}{1-r}$

Step-by-step explanation:

Taking the succession:

$1+r+r^{2}+r^{3}+.....+r^{n-1}$

You can multiply and divide by 1-r without chaging the result:

$\frac{1-r}{1-r} (1+r+r^{2}+r^{3}+.....+r^{n-1})$

Distributing the upper part of the fraction you have:

$\frac{1}{1-r} (1-r+r-r^{2}+r^{2}-r^{3}+r^{3}-r^{4}+.....+r^{n-1}-r^{n})$

As can be seen all the intermediate members will be canceled by a same member with opposite sign, only $(1-r^{n})$ will be left so:

$1+r+r^{2}+r^{3}+.....+r^{n-1} = \frac{1-r^{n}}{1-r}$

An architect designs two houses that are shaped and positioned like a part of the branches of the hyperbola whose equation is wh

kogti [31]

Answer:

40 yards

Step-by-step explanation:

Data:

The hyperbola equation is expressed as follows:

$625y^{2} -400x^{2} = 250 000$

Dividing each term by 250 000 gives:

$\frac{625y^{2} }{250 000} - \frac{400x^{2} }{250 000} = \frac{250 000}{250 000}$

$\frac{y^{2} }{400} - \frac{x^{2} }{625} = 1$

thus:

a² = 40

Therefore, the houses will be 20 yards apart.
