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.
Answer:
true
false
false
true I think don't hold me on it
Q+2=-6q+3+120
Q+2= -6q+123
+6q +6q
7q+2=123
-2. -2
7q =121
Divide by 7 on each sides to get
q= About 17
Alright so .25 oz is 1/4 of 1oz. Therefore you take 28 and divide it by 4 and get 7.
Then take 3500 and divide it by 7 which makes 500 thumb tacks.
I think idk though.
