Using the formula a² + b² = c² but reversing it to c² - b² = x² where x replaces the a for comprehension reasons
so this is the formula
c² - b² = x²
insert the numbers on the triangle in the picture
21² - 8² = 377
since 377 is squared and not the side length, we need to square root it to find x
√377 = 19.4~
Answer: x = 19.4
1) Yes
2) 5 minutes
3) 2 minutes
Step-by-step explanation:
1: Yes because, using the vertical line test, the line will cut the graph once meaning that the graph will form a function
2: 5 minutes because the horizontal line represents that she rested, therefore she was at the park for five minutes
3: 2 minutes because she traveled and reached home between 6 and 8 minutes
The picture is very blurry but the answer is 1 and 2
<span>The partial derivative of the given function with respect to x is
a - by/cx2 + dy/dx
In this derivative the terms in the with x is only considered other or treated as constant
The partial derivative of the given function with respect to y is
b/cx+ d2y/dx.
In this derivative the terms in the with x is only considered other or treated as constant</span>
6x3+49x2+126x+104 (I just simplified it, if it is incorrect I'm sorry I didnt understand what you were asking -,^-)
