What is the formula of LSD in a cuboid?

1 answer:

8 0

Answer: The volume of a cuboid is given by the formula V = LWH, and the surface area of a cuboid is given by the formula SA = 2lh + 2wh + 2lw where l = length, w = width, and h = height.

And i was just learning this a few days back lol

Simplify the expression. x4y−4z−2x2y−2z4 y2x2z6 the fraction with numerator y squared and denominator x squared z to the 6th pow

Kaylis [27]

Given:

Consider the given expression is:

$\dfrac{x^4y^{-4}z^{-2}}{x^2y^{-2}z^4}$

To find:

The simplified form of the given expression.

Solution:

We have,

$\dfrac{x^4y^{-4}z^{-2}}{x^2y^{-2}z^4}$

By using the quotient property of exponents, we get

$=x^{4-2}y^{-4-(-2)}z^{-2-4}$ $\left[\because \dfrac{a^m}{a^n}=a^{m-n}\right]$

$=x^{2}y^{-4+2}z^{-6}$

$=x^{2}y^{-2}z^{-6}$

By using negative exponent property, we get

$=\dfrac{x^{2}}{y^{2}z^{6}}$ $\left[\because a^{-n}=\dfrac{1}{a^n}\right]$

The simplified form of the given expression is $\dfrac{x^{2}}{y^{2}z^{6}}$ .

Therefore, the correct option is B.

Equality Properties

Multiplication Property of Equality
Division Property of Equality
Addition Property of Equality
Subtraction Property of Equality

Step-by-step explanation:

Step 1: Define

2/3(6h - 9) = 6

Step 2: Solve for h

[Division Property of Equality] Divide 2/3 on both sides: 6h - 9 = 9
[Addition Property of Equality] Add 9 on both sides: 6h = 18
[Division Property of Equality] Divide 6 on both sides: h = 3

Find the work done by a force of 4 pounds acting in the direction of 41° to the horizontal in moving an object 5 feet from (0, 0

babymother [125]

F = 5 p
d = 5 ft
The work formula:
W = F * d
W = 5 p * cos 41° * 5 ft = 4 * 0.75471 * 5 = 15.09 ft-lb ≈ 15.1 ft-lb
Answer: C ) 15.1 ft-lb

I need this please anyone

irina [24]

Answer:

Combination; number of ways = 15.

Step-by-step explanation:

Given that there are 6 people in the contest. So it means n = 6.

Two winners each win gift cards. So it means r = 2.

Each gift card is same, so both persons are equally important. It means the order does not matter here, so it is the case of Combinations. We will use nCr formula.

Total number of ways = 6C2 = (6*5)/2 = 15.

Hence, Combination; number of ways = 15.

Help!!!!!!!!!!!!!!!!

Answer:

If the input is n then the output f(n) will be 4n - 8.

Step-by-step explanation:

Let the input of the function is denoted by x and the output is denoted by y.

Then, two ordered pairs of the linear function i.e.(x,y) are (2,0) and (3,4).

Therefore, the relation between x and y i.e. the equation of the straight line will be given by

$\frac{y - 4}{4 - 0} = \frac{x - 3}{3 - 2}$

⇒ y - 4 = 4(x - 3)

⇒ y = 4x - 8

⇒ f(x) = 4x - 8

Therefore, if the input is n then the output f(n) will be 4n - 8. (Answer)
