Answer:
3.2
Step-by-step explanation:
x² + xy = 20
Take the derivative with respect to time:
2x dx/dt + x dy/dt + y dx/dt = 20
(2x + y) dx/dt + x dy/dt = 20
Given x = -5, y = 1, and dx/dt = -4:
(2(-5) + 1) (-4) + (-5) dy/dt = 20
(-10 + 1) (-4) − 5 dy/dt = 20
36 − 5 dy/dt = 20
5 dy/dt = 16
dy/dt = 3.2
The answer would be: 67.89 x 10^6
The rules of significant numbers used:
- any non-zero digit is significant
- zeroes that are in the right side of the non-zero whole number would not be significant
Thus, only the significant numbers left in the equation:
67.89 x 10^6
Answer:
3.78541
Step-by-step explanation:
but if not technical it is 4
Answer:
I believe it's SSS
Step-by-step explanation:
This is because all sides are congruent to each other.
You will need 28 rows because if you divide 224 by 8 you would get 28 (:
