To answer the question above, convert the given measurement of the angle in revolutions. The conversion factor is 1 revolution is equal to 2π or 6.28 radians.
                      (16.2 rev) x (6.28 rad / 1 rev) = 101.736 rad
Then, divide the value obtained with time which is 7. The answer is approximately 14.53 rad/s.

Urgent answer please <br> Ax+ay+xa+ya
marin [14]

Answer:

Possible derivation:

d/dx(a x + a y(x) + x a + y(x) a)

Rewrite the expression: a x + a y(x) + x a + y(x) a = 2 a x + 2 a y(x):

= d/dx(2 a x + 2 a y(x))

Differentiate the sum term by term and factor out constants:

= 2 a (d/dx(x)) + 2 a (d/dx(y(x)))

The derivative of x is 1:

= 2 a (d/dx(y(x))) + 1 2 a

Using the chain rule, d/dx(y(x)) = (dy(u))/(du) (du)/(dx), where u = x and d/(du)(y(u)) = y'(u):

= 2 a + d/dx(x) y'(x) 2 a

The derivative of x is 1:

= 2 a + 1 2 a y'(x)

Simplify the expression:

= 2 a + 2 a y'(x)

Simplify the expression:

Answer:  = 2 a

BRAINLEST FOR RIGHT ANSWER<br><br><br><br> 6. Which rule matches the function shown in the graph?
svetlana [45]

For this case we have a function of the form:

y = mx + b

Where,

m: slope of the line

b: cutting point with the y axis.

The line cuts to the y-axis at the point:

(x, y) = (0, 0)

Therefore, the value of b is given by:

b = 0

We now look for the slope of the line.

For this, we use the following equation:

m=\frac{y2-y1}{x2-x1}

Substituting values we have:

m=\frac{1-0}{3-0}

Rewriting:

m=\frac{1}{3}

Then, the equation of the line is:

y=\frac{1}{3}x

Answer:

the rule that matches the function shown in the graph is:

y=\frac{1}{3}x
