Lax varies directly with y. When x=32,y=8. If y=44, what does x equal?
Irina-Kira [14]
X varies directly with y means x=ky

k is the constant of variation


given when x=32 and y=8
32=8k
divide by 8
4=k

so
x=4y

when y=44

x=4(44)
x=176

x=176 when y=44

g Question 11 pts A set of three vectors in R 4 could possibly be a linearly independent set of vectors. can never span R 4. can
cricket20 [7]

Answer:

Step-by-step explanation:

We will solve this questions using some dimensionality analysis.

a) Note that \mathbb{R}^4 is a vector space of dimension 4. So, given a set of three vectors, they could be or could not be linearly independent. However, if they were, they would not span \mathbb{R}^4 since in order for us to span \mathbb{R}^4 we need 4 or more vectors. Since a set of three vector cannot span this space, they automatically cant be a basis for \mathbb{R}^4.

b)  \mathbb{R}^3 has a dimension 3. So, for a set of vectors A to span this space, we need that A contains at least 3 vectors that are linearly independent. So A could have possibly infinite number of vectors as long as there is a subset of A that is composed by 3 linearly independent vectors.

Can you show me the steps to factor out 8x^3 - 27y^3?
Travka [436]

(2x-3y)(4x^2+6xy+9y^2) is the factored form of 8x^3-27y^3

<em><u>Solution:</u></em>

We have to factor the given expression

8x^3-27y^3

We can use the algebraic identity to factor the given expression

a^3-b^3=(a-b)(a^2+ab+b^2)

Lets make the given expression in form of a^3-b^3

8x^3-27y^3=(2)^3(x)^3-(3)^3(y)^3

8x^3-27y^3=(2x)^3-(3y)^3

Now apply the algebraic property in above expression

Here, a = 2x and b = 3y

Therefore,

(2x)^3-(3y)^3=(2x-3y)((2x)^2+(2x)(3y)+(3y)^2)

(2x)^3-(3y)^3=(2x-3y)(4x^2+6xy+9y^2)

Thus the given expression is factored out

Find the equation of the horizontal asymptote for the function, f of x equals the quotient of the quantity x raised to the 2nd p
ankoles [38]
From your wording, I understand:
f(x) = x^2-100(x-100)

Is this right? Can you edit your question to actually have the equation instead of words!?
