Answer:
3)
Step-by-step explanation:
The aides of a right triangle will always satisfy the Pythagorean relationship ...
a² + b²= c²
We can take each of these and try it out:
(1) ... 10² + 24² = 100 + 576 = 676
√676 = <em>26 Yes</em>.
(2) ... 12² + 18² = 144 + 324 = 468
√468 = 21.6, not 20. <em>No.</em>
(3) ... 15² + 26² = 225 + 676 = 901
√901 = 30.017 Awfully close. As an engineer, I'll buy this one. <em>Yes.</em>
(4) ... 40² + 50² = 1,600 + 2,500 = 4,100
√4,100 = 64.03, not 80.<em> No.</em>
Notice the dependent and independent variables. X axis is usually the independent while y is the dependent. The dependent variable is affected by the independent one. Ravi is driving at a constant speed, which one looks like it is not changing in any direction whatsoever? But, Ravi is speeding up, so which one is adding the speeding (moving up) part of Ravi's driving? And finally, what graph also showcases the visual of Ravi slowing down after he was driving at a constant speed and then speeding up (hint: straight, up, down)?
