Step-by-step explanation:
<h3> The missing data is: " The cost of renting a conoe to use on River Y costs $28. The cost of renting a conoe to use on River Z costs $3 per hour plus a $13 deposit".</h3>
Let's find the first equation.
You know that the cost of renting a conoe to use on River Y costs $28. This is:
To find the second equation you need to remember the Slope-Intercept form of a Linear equation. This is:
Where "m" is the slope and "b" is the y-intercept.
Since the cost of renting a conoe to use on River Z costs $3 per hour plus a $13 deposit, you can identify that:
Therefore, the equation that represents this situation is:
So, the System of equations that could be used to find the total cost "c" of renting a canoe for "n" hours, is:
So remember the acronym "SOH CAH TOA"
- Sin = Opposite/Hypotenuse
- Cos = Adjacent/Hypotenuse
- Tan = Opposite/Adjacent
- Opposite = Side that doesn't touch the angle
- Adjacent = Side that touches the angle
- Hypotenuse = Side that is across from the right angle
So we see that side a doesn't touch angle , hence making it the opposite side. And we see that side b is across from the right angle, making it the hypotenuse. <u>Using this info,
</u>
So we already know from part A that side b is the hypotenuse. And also since side c touches the angle, it is the adjacent.<u> Using this info, </u>
Next, it has been established that side c is the adjacent and side a is the opposite side. <u>Using this info, </u>
