Answer:
180-43
Step-by-step explanation:
43 and x are supplementary which means they both should equal 180
2200 / 264 = 8.333333-
Round the answer, which is 8.
So, your answer is A. 8%
Answer:
990.36$
Step-by-step explanation:
You times 18 by 42 then you get 756 then you times that by 1.31$
Answer:
The correct option is;
Increasing one fifth unit/sec
Step-by-step explanation:
The equation that gives the curve of the particle of the particle is y = 5·x² - 1
The rate of decrease of the y value dy/dt = 2 units per second
We have;
dy/dx = dy/dt × dt/dx
dy/dx = 10·x
dy/dt = 2 units/sec
dt/dx = (dy/dx)/(dy/dt)
dx/dt = dy/dt/(dy/dx) = 2 unit/sec/(10·x)
When x = 1
dx/dt = 2/(10·x) = 2 unit/sec/(10 × 1) = 1/5 unit/sec
dx/dt = 1/5 unit/sec
Therefore, x is increasing one fifth unit/sec.
