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:
10/3

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°.

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]

A circle on a coordinate plane, center at the origin, B, radius 1. Points on the circle, A, at 1 comma 0, C in the first quadrant, D in the second quadrant, E in the fourth quadrant. Segment B C.
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).

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.

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
