The table shows your scores in a skateboarding competition. The leader has 311.62 points. Select the equation that you can use to find how many points p you need in the fourth round to tie the leader. Then solve the equation to determine how many points you need in the fourth round to take the lead in the competition.
Find the second part please.
Answers
Answer:
✅[tex] p + 63.43 + 87.15 + 81.96 = 311.62 [/tex]
✅To take the lead, your score in the fourth round must be greater than 79.08.
Step-by-step explanation:
If you score, 63.43, 87.15, 81.96 in the first, second and third round respectively, if the current leader has a total score of 311.62 points, the point p that you need to score to equal 311.62 points, can be found using the following equation:
[tex] p + 63.43 + 87.15 + 81.96 = 311.62 [/tex]
Solve for the value of p
[tex] p + 232.54 = 311.62 [/tex]
Subtract 232.54 from each side
[tex] p = 311.62 - 232.54 [/tex]
[tex] p = 79.08 [/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
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

(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:

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]
