Answer:

Sinx = 5/13

cosy = 5/13

cosy = sinx ; they both share a proportional relationship

Step-by-step explanation:

From the attached triangle, since the triangle is right angled, we can use trigonometric functions where ;

sinx° = opposite / hypotenuse

From Pythagoras ;

Hypotenuse = √(opposite² + adjacent²)

Hypotenus = √(12² + 5²)

Hypotenus = 13

Sin x° = opposite / hypotenus = 5 / 13

Sin x° = 5/13

Cos y = adjacent / hypotenus = 5 / 13

Hence,

sinx = cosy

Therefore, they both share a proportional relationship.

A machine wheel spins at a rate of 500 revolutions per minute. If the wheel has a diameter of 80 centimeters, what is the angula
solmaris [256]

Answer: 3,140 radians per minute.

Step-by-step explanation:

We know that the wheel does 500 revolutions per minute.

This is called the frequency of the wheel, and this is written as:

f = 500 rev/min = 500 RPM

The angular speed (or Angular velocity) is written as

ω = 2*pi*f

And this quantity is in radians/unit of time.

where pi = 3.14

then:

ω = 2*3.14*500 (rev/min)*(rad/rev) = 3,140 rad/min

This means that the angular velocity  (or angular speed) is 3,140 radians per minute.

Lady bird [3.3K]

Answer:

Yes, they started with equal expressions.

Step-by-step explanation:

To simplify Vanessa's expression, we must rationalize the denominator.  This means we must make the denominator x.

We need to multiply the denominator by x^(1/6) to make a whole x; this means we must multiply the numerator by x^(1/6) as well:
