A full rotation is 360 degrees so the required angle is 360/12 = 30 degrees.
Answer: 55cm^2
Step-by-step explanation:Area of a parallelogram= bh, so the base and height for this new one are base of 11 and height 5. so 11*5=55
For every 9 kids 5 are girls
there are 3 sets of 9
so 5 x 3 = 15
there are 15 girls
I believe it would be 72cm^2
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.
