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

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

(8 - h)(jh + jh) use h=-1 and j=5
I would do this but im kind of confused please help
Answers
Answer:
-90
Step-by-step explanation:
(8-h)(jh+jh)
Since the values of h and j are given, we use substitution to replace the variables with their number values
(8-(-1))(j(-1)+j(-1) replaced all the h with -1
(8-(-1))((5)(-1) + (5)(-1)) replaced all the j with 5
Then we solve inside the parenthesis first
(8+1)(-5+(-5))
(9)(-10)
Then, multiply

Equation of (y - k)^2 = 4p (x - h), where the focus is (h + p, k) and the directrix is x = h - pGiven 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 = -1Focus is
(h +p, k) = (- 0.75, -1)Directrix is:

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]
