Look at the expressions inside the brackets - they are the same!! basically you have an equation in the form of
$4a + 3a$
where
$a= ( \sqrt[5]{ {x}^{2} {y} } )$

the answer is the 3rd option.

Answer:

P U Q = {2, 3, 4, 5, 6, 7, 8, 9, 10}

P ∩ Q = {4, 6, 8}

Step-by-step explanation:

P = {2x, for 1 <= x <= 5}

P = {2, 4, 6, 8, 10}

Q = {x + 1, for 2 <= x <= 8}

Q = {3, 4, 5, 6, 7, 8, 9}

P U Q = {2, 3, 4, 5, 6, 7, 8, 9, 10}

P ∩ Q = {4, 6, 8}

A record of radius 15 cm is spinning at 45 revolutions per minute. What is the linear speed, in cm/min, of a point on the rim of

Afina-wow [57]

What you need to know for this case is that the linear velocity is defined as the product of the angular velocity by the radius.
We have then:
v = w * r
Substituting the values:
v = (45) * (15) = 675
v = 675 cm / min
answer:
The linear speed, in cm / min, of a point on the rim of the record is:
v = 675 cm / min
