Answer:
![y=80x+25](https://tex.z-dn.net/?f=y%3D80x%2B25)
Step-by-step explanation:
Let
x ----> the number of hours
y ---> the total cost of renting a jet ski in dollars
we know that
The linear equation in slope intercept form is equal to
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
where
m is the slope or unit rate of the linear equation
b is the y-intercept or initial value
In this problem we have
The slope is equal to
![m=\$80\ per\ hour](https://tex.z-dn.net/?f=m%3D%5C%2480%5C%20per%5C%20hour)
we have the ordered pair (3,265)
substitute in the linear equation
![265=80(3)+b](https://tex.z-dn.net/?f=265%3D80%283%29%2Bb)
solve for b
![265=240+b](https://tex.z-dn.net/?f=265%3D240%2Bb)
![b=265-240](https://tex.z-dn.net/?f=b%3D265-240)

substitute
![y=80x+25](https://tex.z-dn.net/?f=y%3D80x%2B25)
Answer:
The length side of the triangle is ![\frac{10\sqrt{3}}{3}\ cm](https://tex.z-dn.net/?f=%5Cfrac%7B10%5Csqrt%7B3%7D%7D%7B3%7D%5C%20cm)
Step-by-step explanation:
we know that
The equilateral triangle has three equal sides and three equal internal angles of measure of 60 degrees each.
Let
b------> the length side of the equilateral triangle
Applying Pythagoras theorem
![b^{2}=(b/2)^{2}+5^{2}\\\\ b^{2}-(b/2)^{2}=25\\\\ (3/4)b^{2}=25\\ \\b^{2} =25*4/3\\ \\b=\frac{10}{\sqrt{3}}\ cm\\ \\b=\frac{10\sqrt{3}}{3}\ cm](https://tex.z-dn.net/?f=b%5E%7B2%7D%3D%28b%2F2%29%5E%7B2%7D%2B5%5E%7B2%7D%5C%5C%5C%5C%20b%5E%7B2%7D-%28b%2F2%29%5E%7B2%7D%3D25%5C%5C%5C%5C%20%283%2F4%29b%5E%7B2%7D%3D25%5C%5C%20%5C%5Cb%5E%7B2%7D%20%3D25%2A4%2F3%5C%5C%20%5C%5Cb%3D%5Cfrac%7B10%7D%7B%5Csqrt%7B3%7D%7D%5C%20cm%5C%5C%20%5C%5Cb%3D%5Cfrac%7B10%5Csqrt%7B3%7D%7D%7B3%7D%5C%20cm)
