The percent of change from Week 2 to Week 3 is  6.8%

What is the percentage change?

Percentage is the ratio of an amount that is expressed as a number out of 100. Percentage is a measure of frequency. The sign that is used to represent percentage is %.

The percent of change from Week 1 to Week 2 = (number of sit ups in week 2 / number of sit ups in week 1) - 1

(44 / 40) - 1 = 0.1 = 10%

The percent of change from Week 2 to Week 3 = (number of sit ups in week 3 / number of sit ups in week 2) - 1

If the measure of angle 1 = 2x+3 and the measure of angle 2 = 3x+2, then what is the measure of angle 3?

Answers

Answer: 126°

Step-by-step explanation:

Step-by-step explanation: Since every triangle has 180 interior degrees, we can say 2x + 3x + 90° = 180°. Subtract 90° from each side and we get

2x + 3x = 90°

5x = 90°

x = 18°

Plug in x for Angle 2, giving us Angle 2 = 54°

Angle 1 and angle 2 must add up to 180°

Subtract 54° from 180° and we get 126°

Please help!! Find the values of x and y.

Answers

The values of x and y will be 100° and 10° when two parallel lines are being cut by a transversal line.

According to the question,

We have a figure where two parallel lines are being cut by a transversal line.

Now, we know that the angles formed on a straight line is 180° and vertically opposite angles are equal.

The sum of consecutive interior angles is 180°.

Now, we will use these three statements in finding the values of x and y.

Now, adding (2x-70)° and (5y)° will give 180° because the angles made are on a straight line.

(2x-70)°+(5y)° = 180°

2x+5y = (180+70)°

2x+5y = 250° .... (1)

Now, (x+30)° will be the interior angle consecutive to 5y° because they are vertically opposite angles.

So, we have:

(x+30)°+5y° = 180°

x+5y = (180-30)°

x+5y = 150°

5y = 150-x

Now, putting this value of 5y in equation 1:

2x+5y = 250

2x+150-x = 250

x+150 = 250

x = (250-150)°

x = 100°

Now, we will find the value of y:

5y = 150-x

5y = 150-100

5y = 50

y = 50/5

y = 10°

(Note that the values of x and y will be in ° because angles are measured in degree.)

Hence, the value of x is 100° and the value of y is 10°.

How to find the equation of the parallel line?

Here we want to find a linear equation parallel to:

Now, a general linear equation is:

y = m*x + b

Where m is the slope and b is the y-intercept.

Remember that two lines are parallel if and only if the lines have the same slope and different y-intercept.

So our linear equation will be something like:

y = 3*x + c

Now we also want our line to pass through the point (4, 6), then we can replace these values:

6 = 3*4 + c

6 = 12 + c

6 - 12 = c

-6 = c

Equation of 'm'

y = - ³/₅ x + ³⁶/₅    [slope-intercept form]

Equation of 'q'

(y - 6) = ⁵/₃ (x - 2)         [point-slope form]

y = ⁵/₃ x + ⁸/₃         [slope-intercept form]

How to find the equations of lines m and q?

To find the equation for both 'm' and 'q' requires a bit of work. Because neither  'm' nor 'q' has two points to find the slopes of the line, we have to get creative.

The Line 'n' has two points [ (4, 4) & (1, -1) ], and as such we can find the slope of that line. The line 'n' is parallel with 'q' and perpendicular with m.

For finding the slope of 'n'

The slope of the 'n'    =  (y₂ - y₁) ÷ (x₂ - x₁)      

=  (4 - (- 1)) ÷ (4 - 1)  

=  5 ÷ 3

=  ⁵/₃

To estimate the slope of 'q' and 'm'

When two lines exists parallel, they contain the exact slope.

Since 'n' and 'q' exists parallel,

then the slope of q = ⁵/₃

When two lines exists perpendicular, the product of their slopes exists -1. This means that the slopes exists negative-reciprocals of each other.  

Since 'n' and 'm' exists perpendicular

then the slope of m = - ³/₅

Write the equation for 'q' and 'm'

We can now utilize the point-slope form (y - y₁) = m(x - x₁)) to write the equation for the lines

For both 'q' and 'm' let (x₁, y₁) be (2, 6)

Equation of 'm'

(y - 6) = - ³/₅ (x - 2)     [point-slope form]

y = - ³/₅ x + ³⁶/₅    [slope-intercept form]

Equation of 'q'

(y - 6) = ⁵/₃ (x - 2)         [point-slope form]

y = ⁵/₃ x + ⁸/₃         [slope-intercept form]

Set theory, a branch of mathematical logic, studies sets, which are essentially collections of objects.

Despite the fact that every form of object may be turned into a set, set theory is a branch of mathematics that primarily deals with issues that are relevant to mathematics as a whole.

The foundation of set theory is a straightforward binary link between an object o and a set A.

If o is a component (or member) of A, it is expressed as o A. When listing members of a set, commas are used to indicate their separation, or brackets are used to surround a property of those parts.

Since sets are objects, they can be connected by the membership relation.

Given set U = {11,12,13,14,15,16,17,18,19,20}

A = {12,14,16,18,20}

B = {12,15,18}
