Answer:
There are exactly 42 generators of U(49), one for each power of g (g^0, g^1, g^2, ..., g^41).
Step-by-step explanation:
We know that the group U(49) is cyclic, so it has at least one generator. Let's call this generator g. Since U(49) has 42 elements, we know that g^42 = 1 (where 1 is the identity element of the group).
This is because the order of g must divide the order of the group, so the order of g can be 1, 2, 7, 14, 21, or 42.
Now, suppose there exists another generator h. This means that h has order 42 (since it generates the entire group).
However, since U(49) is cyclic, there exists an integer k such that h = g^k. Therefore, (g^k)^42 = g^(42k) = 1, which implies that 42 divides k. In other words, k must be a multiple of 42.
Conversely, if we let k be a multiple of 42, then (g^k)^42 = g^(42k) = 1. Therefore, the element g^k has order 42, and since it generates the entire group, it is also a generator of U(49).
So we have shown that if g is a generator of U(49), then any generator h can be written as h = g^k for some multiple k of 42.

Hideki buys 2 sweaters for $18 each. He can use one of the following coupons :
Coupon 1: Buy one, get one 40% off
Coupon 2: 25% off entire purchase
Which coupon should Hideki use to get a better deal?
Hideki should use coupon 2 to get a better deal.
What is percentage?Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
Given that, Hideki buys 2 sweaters for $18 each.
Coupon 1: Buy one, get one 40% off
Here, 40% of 18
= 40/100 ×18
= 0.4×18
= $7.2
So, cost of entire purchase 2(18)-7.2
= 36-7.2
= $28.8
Coupon 2: 25% off entire purchase
25% of 2(18)
= 25/100 ×36

What does 1 2 scale mean?
If the scale factor is a fraction, the shape will be smaller. This is called reduction. Therefore, a 1/2 scaling factor means that the new shape is half of the original shape.
What is 1 2 scale?Half scale is 1:2. It is helpful to think of this as one unit on the drawing equals two units on the object. A small object can be enlarged on the paper and drawn in 2:1 scale. This means the drawing of the object is twice as large as the object itself.This means that one unit on the page represents one unit in 'real life'. If a drawing is drawn HALF the actual size of the object, the scale is 1:2. This means that one unit on the page is equal to two units in real life.They are a reference to the original drawing size. For example, if a drawing file is currently sized at 24″x36″, then a full size print of that file would be 24″x36″.

What is ed? enter your answer in the box. units two segments a d and b c intersect at point e to form two triangles a b e and d c e. side a b is parallel to side d c. a e is labeled 2 x plus 4. e d is labeled x plus 4. c d is 6. a b is 9.
The total area of the two triangles is 3 sq units + (-1 sq units) = 2 sq units.
The equation of line a b is y = 2x + 4
and the equation of line d c is y = x + 4
Substituting the y-coordinate of point E, (6) in the equations of line a b and d c, we get:
2x + 4 = 6
x + 4 = 6
Solving the above equations, we get x = 1 and y = 6.
Therefore, the coordinates of point E are (1,6).
The length of side a b is 9 - (2x + 4) = 9 - (2(1) + 4) = 3
The length of side d c is x + 4 - 6 = 1 + 4 - 6 = -1
The length of side a e is 2x + 4 - 6 = 2(1) + 4 - 6 = 2
The length of side d e is x + 4 - 6 = 1 + 4 - 6 = -1
Therefore, the area of triangle a b e is 1/2 (base x height) = 1/2 (3 x 2) = 3 sq units
The area of triangle d c e is 1/2 (base x height) = 1/2 (-1 x 2) = -1 sq units

The value of x in the quadrilateral is 23°
How to find the value of x in the quadrilateral?
Geometry is a branch of mathematics that deals with shapes, angles, dimensions and sizes of different things we see in everyday life
The interior angles of the quadrilateral are :
180 - (x+16)° (sum of angles on a straight line)
180 - (3x-1)° (sum of angles on a straight line)
180 - 6x° (sum of angles on a straight line)
180 - 5x° (sum of angles on a straight line)
Since the sum of the interior angles of a quadrilateral is 360°. We have:
180-(x+16)° + 180-(3x-1)° + 180-6x° + 180-5x° = 360°
180 - x - 16 + 180 - 3x + 1 + 180 - 6x + 180 -5x = 360
705 - 15x = 360
15x = 705 - 360

On solving the provided question, we can say that the linear function that can be formed is x + 4y= 16 and rate of change in linear function is 13
What is linear function ?Two distinct but related concepts are referred to as linear functions in mathematics. A polynomial function of degree 0 or 1 is a linear function in calculus and related subjects if its graph is a straight line. Any function that depicts a straight line on a coordinate plane is said to be linear. For instance, y = 3x - 2 is a linear function since it depicts a straight line on the coordinate plane. f(x) = 3x - 2 can be used to represent the function since f(x) can be linked to y.
the linear function that can be formed is
x + 4y= 16
also, 2x = 26y

The average person in a slum in a developing region uses 1.32 gallons (5 liters) of water every day. If the average shower in the US uses 7.5 gallons of water a minute how long of a shower would it be to use 1.32 gallons?
One gallon equals 16 eight ounce glasses of water.
A one-minute shower consumes how many gallons?According to the EPA, conventional shower heads utilize 2.5 gallons of water each minute. For the normal shower, that’s 20 gallons of water! To help lower your water impact, try trimming three minutes off your shower time. Delivering, purifying, and boiling hot water for your shower also consumes a lot of energy.
To determine the average shower water use, multiply the average flow rate of 2.1 gallons per minute by the average shower time of 8.2 minutes. So, 17.2 gallons is the average amount of water utilized. A 10-minute shower will consume 21 gallons of water. The amount of water consumed in the shower may quickly add up.

Which correctly describes how to determine the measure of angle 1? 2 parallel lines are crossed by a transversal to form 8 angles. clockwise from top left, the angles are 105 degrees, blank, blank, blank; blank, blank, 2, 1. the 105° angle and angle 2 are alternate exterior angles so angle 2 must measure 105°. angles 1 and 2 are supplementary angles so angle 1 must measure 75°. the 105° angle and angle 2 are corresponding angles so angle 2 must measure 105°. angles 1 and 2 are supplementary angles so angle 1 must measure 75°. the 105° angle and angle 2 are alternate exterior angles so angle 2 must measure 75°. angles 1 and 2 are supplementary angles so angle 1 must measure 105°. the 105° angle and angle 2 are corresponding angles so angle 2 must measure 75°. angles 1 and 2 are supplementary angles so angle 1 must measure 105°.
Option A is the correct answer. the 105° angle and angle 2 are alternate exterior angles so angle 2 must measure 105°. angles 1 and 2 are supplementary angles so angle 1 must measure 75°.
Two angles are called supplementary when their measures add up to 180° degrees. These angles form a straight angle when they are put together.
Angle 1 and angle 2 are supplementary if Angle1+Angle2= 180°.Thus, Angle 1 and Angle 2 are called "supplements" of each other.
Two angles that lie on opposite sides of the transversal and are placed on two different lines are called alternate exterior angles. These pairs of angles are always equal if the two given lines are parallel.
Two exterior angles that lie on two different lines cut by a transversal and are placed on opposite sides of the transversal are called alternate exterior angles.
Here,105 and ∠2 are alternate exterior angles, ∠2=105 degrees.
Angles 1 and 2 and supplementary
so 180 - ∠2 = ∠1
180-105=75.
∠1 =75 degrees.
