Answer:
dy/dx = -b/a cot α
Step-by-step explanation:
x² / a² + y² / b² = 1
Take derivative with respect to x.
2x / a² + 2y / b² dy/dx = 0
2y / b² dy/dx = -2x / a²
dy/dx = -b²x / (a²y)
Substitute:
dy/dx = -b²a cos α / (a²b sin α)
dy/dx = -b cos α / (a sin α)
dy/dx = -b/a cot α
In decimal form=-7.37

Answer:
The next number is 127
Step-by-step explanation:
The sequence is the previous number times 2 plus one.
Lab Safety is the main starting point on the scientific process.
My educated guess would be 3 times, since it’s unlikely that you would get it many time because of the low probability. Sorry it incorrect!!
