A rectangle has a length of x and a width of 3x3 + 9 − x2. Find the perimeter of the rectangle when the length is 6 feet. Please HELP :(

Answers

Answer 1

Answer:

24

Step-by-step explanation:

A rectangle as four sides, and as we know, two of the sides equal each other. I would first start by drawing a rectangle. On one length on the outside of the triangle, put x. On the opposite congruent length, put x again since we know the sides are the same. You should have two blank sides left. On both of those sides, put 3x3 + 9 - x2 (I am assuming that you meant x squared whenever you said x2. Let me know if I assumed incorrectly. Because the length is 6, we know that x must be six. Now substitute everything that says x with the number six. Use parenthesis so you don't confuse it with other numbers. (6.) Now add everything up. You should be adding 3x3 + 9 - (6)2+ 3x3 + 9 - (3)2 + 6 + 6. Your final answer should be 24.

Then again, because this question could of meant 2x rather than x^2, this could be completely wrong, so if you take a picture of the exact question I will be able to help you better. Also, I'm not sure if your 3x3 is an x or an multiplication sign.

Karly is choosing between two health clubs. Yoga Studio A charges a membership fee of $22.00 and $24.50 per month. Yoga Studio B charges a membership fee of $47.00 and $18.25 per month. At how many months will they cost the same? *

Answers

Answer:

4 months

Step-by-step explanation:

Given

Studio A

[tex]Membership = \$22.00[/tex]

[tex]Monthly = \$24.50[/tex]

Studio B

[tex]Membership = \$47.00[/tex]

[tex]Monthly = \$18.25[/tex]

Required

Determine when the cost will be the same

For both, we have the total cost to be:

[tex]Cost = Membership + Monthly\ Cost * m[/tex]

Where m represents the number of month

For Studio A:

[tex]Cost = 22 + 24.5 * m[/tex]

For Studio B:

[tex]Cost = 47 + 18.25 * m[/tex]

Equate both expressions to get the required month

[tex]47 + 18.25 * m = 22 + 24.5 * m[/tex]

[tex]47 + 18.25 m = 22 + 24.5m[/tex]

Collect Like Terms

[tex]47 - 22 = 24.5m - 18.25 m[/tex]

[tex]25= 6.25m[/tex]

Reorder

[tex]6.25m = 25[/tex]

Solve for m

[tex]m = 25/6.25[/tex]

[tex]m = 4[/tex]

Hence, it'll take 4 months

Solve the system
u=2x-y v= 3 x+2y​, for x and y in terms of u and v then find the value of Jacobian σ(x,y)/σ(u,v). Find the image under the transformation of the triangular region with the vertices (0,0) ,(2,4), and (2, -3) in the x,y plane. Sketch the transformed region in uv plane.The function for x in terms of u and v is x=?

Answers

Answer:

x = [tex]\frac{2u+v}{7}[/tex]

y =  [tex]\frac{2v - 3u }{7}[/tex]

Jacobian value = 1/7

Step-by-step explanation:

Given data:

u = 2x -y

v = 3x + 2y

solving the system for  x and  y in terms of u and v

x = [tex]\frac{2u+v}{7}[/tex]

y =  [tex]\frac{2v - 3u }{7}[/tex]

The value of the Jacobian =  1/7 ( solution attached below )

Image under the transformation of the triangular region with vertices ( 0,0) , (2,4) and (2,-3) in the x-y plane is attached below

In this exercise we have to use system and Jacobian knowledge to calculate the requested values, thus we find that:

 [tex]X= \frac{2u+v}{7} \\\\Y= \frac{2v-3u}{7}\\\\J= \frac{1}{7}[/tex]

Given data as:  

[tex]u = 2x -y[/tex] [tex]v = 3x + 2y[/tex]

Solving the system for  x:

[tex]2u=4x-2y\\v= 3x-2y\\= 2u+v/7[/tex]

Solving the system for  v:

[tex]u = 2(2u+v/7)-y\\y= 1/7(2v-3u)[/tex]

Find the value of the Jacobian:

[tex]\frac{dx}{du}= \frac{d(2u+v/7)}{du}= 2/7\\\\\frac{dv}{du}= \frac{d(2u+v/7)}{du}= 2/7[/tex]

[tex]\frac{dx}{du}= \frac{d(2v+3u/7)}{du}= -3/7\\\\\frac{dv}{du}= \frac{d(2v+3u/7)}{du}= 2/7[/tex]

Substitute the given value in equation will become:

[tex]J= 1/7[/tex]

Determine whether the set W is a subspace of R3 with the standard operations. If not, state why.
W = {(0, x2, x3): x2 and x3 are real numbers}
W is a subspace of R3.
W is not a subspace of R3 because it is not closed under addition.
W is not a subspace of R3 because it is not closed under scalar multiplication.

Answers

Answer:

Step-by-step explanation:

From the given information.

R3 is a vector space over the field R, where R is the set of real numbers.

Where;

The set W = {(0, x2, x3): x2 and x3 are real numbers} is the subspace of [tex]\Re[/tex]³

To proof:

(0,0,0) ∈ W ⇒ W ≠ ∅

Suppose u and v is an element of W;

i.e.

u,v ∈ W (which implies that) ⇒ u (0,x2,x3) and v = (0,y2,y3) are  real numbers.

Then

u+v = (0,x2,x3) +(0, y2, y3)

u+v = (0,x2+y2, x2+y3) ∈ W

⇒ u+v ∈ W  ----- (1)

Now, if we take any integer to be an element  of the real number [tex]\Re[/tex]

i.e

∝ ∈ [tex]\Re[/tex]

∝*[tex]\Re[/tex] = ∝(0,x2,x3)

∝*[tex]\Re[/tex] = (0,x2,x3) ∈ W

⇒ ∝*u ∈ W ------(2)

Thus from (1) and (2), W is a subspace of [tex]\Re[/tex]³

Equation of (y - k)^2 = 4p (x - h), where the focus is (h + p, k) and the directrix is x = h - p

Given is the parabola:

(y + 1)^2 = (x + 2)

It has a vertex at (-2, -1)

New vertex (-1, -1) requires translation to the right by 1 unit. Which changes the function to:

(y + 1)^2 = (x + 2 - 1) ⇒ (y + 1)^2 = (x + 1)

For this function the focus and directrix is:

(y + 1)^2 = (x + 1)k = -1, p = 1/4, h = -1

Focus is

(h +p, k) = (- 0.75, -1)

Directrix is:

x = -1 - 1/4 = - 1.25
