Answer:
B = C = 70°
Step-by-step explanation:
In Triangle ABC, angle A measures 40 degrees.
We need to find the possible angle measures for B and C if ABC is in isosceles triangle.
For an isosceles triangle, two sides of a triangle are equal. We know that if two sides are equal, the corresponding angles are equal. Let equal angles are x. The sum of an isosceles triangle is equal to 180 degrees. So,
40 + x +x = 180
40 + 2 x = 180
2x = 140
x = 70 degrees
So, the possible angle measures for B and C is equal to 70°.

The measure of angle ABD 3pi/4 is radians. What are the approximate coordinates of D? Write your answer in the following format: (x,y) with no spaces. Round your answer to the nearest hundredth.
HELPPPPP
Answer: (-.71, .71)
Step-by-step explanation:
To find the approximate coordinates of point D, we need to consider the angle ABD that measures [tex]3pi/4[/tex]radians.
Since point B is the center of the circle with radius 1 and point A lies on the x-axis at (1, 0), we can calculate the coordinates of point D using trigonometry. First, let's find the coordinates of point B, which is the origin (0, 0). Since the angle ABD measures[tex]3pi/4[/tex] radians, we know that angle ABO is pi/4 radians (complementary angle to ABD).
Using trigonometry, we can find the x-coordinate of point D based on the angle ABO: x-coordinate of D = cos(pi/4) = cos(45 degrees) = 1/sqrt(2) ≈ 0.71 Similarly, using trigonometry, we can find the y-coordinate of point D based on the angle ABO: y-coordinate of D[tex]= sin(pi/4) = sin(45 degrees) = 1/sqrt(2) ≈ 0.71[/tex] Therefore, the approximate coordinates of point D are (0.71, 0.71).

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? *
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

What is the sum of the measures of the exterior angles of a polygon that has fifteen sides?
Answer:
The sum of the measures of the exterior angles of a polygon with 15 sides will be 360°.
Step-by-step explanation:
The Exterior Angle Sum Theorem defines that the sum of the exterior angles of any convex polygon is 360°.Given that a polygon has 15 sides.
If the polygon is regular with 15 sides, it indicates that each exterior angle is
360°/15 = 24°
so the measure of each exterior angle of a 15 sided polygon is 24°.As the polygon has 15 sides, the sum of the measures of the exterior angles of a polygon will be:
15 × 24 = 360°Therefore, the sum of the measures of the exterior angles of a polygon with 15 sides will be 360°.

Which functions are linear?
y=4/x
y=-4x + 1
y= 5(x – 0.6)
Answer:
y=-4x + 1
y= 5(x – 0.6)
Step-by-step explanation:
y = -4x + 1 follows the linear equation of y = mx + b.
y = 5(x - 0.6) can be simplified into y = mx + b by distribution,
y = 5x - 3 which follows the linear equation of y = mx + b.

Answer: = 2 8/11
2 IS THE WHOLE NUMBER
8/11 IS THE FRACTION
Step-by-step explanation:
First
Convert any mixed numbers to fractions.
Then your initial equation becomes:
15/4÷11/8
Applying the fractions formula for division,
=15×84×11
=12044
Simplifying 120/44, the answer is
= 2 8/11
When [tex]3\frac{3}{4}[/tex] is divided by [tex]1\frac{1}{8}[/tex] we get the fraction 10/3.
To divide mixed fractions, we first convert them to improper fractions, and then perform the division.
Let's convert the mixed fractions into improper fractions:
[tex]3\frac{3}{4}[/tex]= (4× 3 + 3) / 4 = 15/4
[tex]1\frac{1}{8}[/tex] = (8 × 1 + 1) / 8 = 9/8
Now, we can divide the fractions:
(15/4) / (9/8)
To divide fractions, we multiply the first fraction by the reciprocal of the second fraction:
(15/4) × (8/9)
30/9
The GCD of 30 and 9 is 3, so divide numerator and denominator by 3:

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=?
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.
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
