An athletic director pays $90 for 12 sun visors for the softball team. The rate per sun visor is equal to $90 / 12 sun visor = $ 7.5 per sun visor. So the athletic director should pay ($ 7.5 per sun visor)*(15 sun visor) = $ 112.5

URGENT HELP NEED!!! I WILL REWARD LOTS OF POINTS FOR THIS QUESTION!!! ANY IRRALEVENT OR SILLY QUESTION WILL BE INSTANTLY REPORTE

Ipatiy [6.2K]

Let the points be A,B,C

A(0,0)
B(24,16)
C(8,20)

$\\ \bull\sf\leadsto AB=\sqrt{(24-0)^2+(16-0)^2}=\sqrt{24^2-16^2}=\sqrt{576-256}=\sqrt{320}=17.4units$ (leg3)

$\\ \bull\sf\leadsto AC=\sqrt{(8-0)^2+(20-0)^2}=\sqrt{8^2+20^2}=\sqrt{64+400}=\sqrt{464}=21.4units$ (leg1)

$\\ \bull\sf\leadsto BC=\sqrt{(24-8)^2+(26-20)^2}=\sqrt{16^2+(-4)^2}=\sqrt{256+16}=\sqrt{272}=16.4units$ (leg2)

We have to find perimeter

$\\ \bull\sf\leadsto Perimeter=AB+AC+BC$

$\\ \bull\sf\leadsto Periemter=17.4+16.4+21.4$

$\\ \bull\sf\leadsto Perimeter=55.2units$

The length of leg3=17.4units

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:

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