Answer:a:If you know the lengths of the two legs of a right triangle, use the Pythagorean theorem to get the length of the hypotenuse (side opposite the right angle). That's √(14² + 9²) = √(196 + 81) = √277 = about 16.64 ft
on b you are given the hypotenuse and one leg so you use the same theorem, just with subtract instead of add:
(18² - 14² ) = (324 - 196) = 128 or about 11.31 ft Hope i helped!!
Step-by-step explanation:
Using a linear function, it is found that he drove the truck for 240 miles.
<h3>What is a linear function?</h3>
A linear function is modeled by:
y = mx + b
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.
Researching the problem on the internet, there was a base fee of $18.99, which is the y-intercept, and there was an additional charge of 75 cents for each mile driven, which is the slope, hence the cost function for m miles driven is given by:
C(m) = 18.99 + 0.75m.
He paid $199, hence the number of miles he drove is found as follows:
C(m) = 18.99 + 0.75m.
199 = 18.99 + 0.75m
m = (199 - 18.99)/0.75
m = 240 miles.
