Which expression is in simplified form for the given expression and states the correct variable restriction? u^2-4/(u-6)(u-2)
a. 1/u-3, u=3
b. u+2/u-6, u=2, u=6
c. 1/2u+12, u=-6
d. u+2/u-6, u=6

Answers

(u^2 - 4) / (u-6)(u-2)

Resriction u ≠ 6 and u ≠ 2 (because the denominator cannot be equal lto zero)

Simplification

 u^2 - 4 is a difference of two squares, then you can factor it as the product of (u+2)(u-2). So, you can write the expression as:

(u+2)(u-2) / (u-2)(u-6)

Simplify u -2 (because it appears in the numerator and the denominator)

(u + 2) / (u -6), with u ≠2 and u≠6

25.83 is 52.5% of what number

Answers

The question asks to find the unknown number - x and we know that 25.83 represents 52.5% of that number. 52.5 % = 0.525. We can make an equation: 0.525 * x = 25.83, where x is the required number. x = 25.83 : 0.525, x = 49.2. Also we can say that x is 100% and 25.83 is 52.5%. Therefore: x : 25.83 = 100 : 52.5; 52.5 x = 100 * 25.83; 52.5 x = 2583; x = 2583 : 52.5; x = 49.2. Answer: the required number is 49.2.

a cross-section is taken parallel to the bases of a general cylinder and has an area of 18. If the height of the cylinder is H, what is the volume of the cylinder? Explain your reasoning.

Answers

∵ the cross-section is parallel to the bases of the cylinder, then it is congruent to the bases thus, the area of the base of the cylinder is 18.
The volume of a general cylinder is the product of the area of the cylinder’s base times the height of the cylinder,
So the volume of the general cylinder is = 18 H

An airplane is traveling at a speed of 200 km/h. Identify the correct conversion factor setup required to compute the speed of the airplane in m/s.

Answers

Answer:

Speed = 55.56 m/s

Step-by-step explanation:

Given:

An airplane is travelling at the speed of 200 km/h.

We need to convert this in meter/second.

1 km = 1000 meters

1 hour = 3600 seconds

Speed = Distance/Time

Speed = (200*1000)/(1*3600)

= 200000/3600 meter/second

Speed = 55.56 m/s

Hope this will helpful.

Thank you.
