Answer:

Starting with the equation:

(x + 1)^2 = 13/4

We can use the square root property, which states that if a^2 = b, then a is equal to the positive or negative square root of b.

Taking the square root of both sides, we get:

x + 1 = ±√(13/4)

Simplifying under the radical:

x + 1 = ±(√13)/2

Now we can solve for x by subtracting 1 from both sides:

x = -1 ± (√13)/2

Therefore, the solutions to the equation are:

x = -1 + (√13)/2 or x = -1 - (√13)/2

Step-by-step explanation:

The expansion and simplification of the expression (x - 2)² is x² - 4x + 4.

An algebraic expression is a combination of variables with constants, numbers, and values using the mathematical operands addition, subtraction, multiplication, or division.

(x - 2)²

Expanding the square:

(x - 2)² = (x - 2)(x -2)

Distributing the square:

x(x - 2) - 2(x - 2)

x² - 2x - 2(x -2)

x² - 2x - 2x + 4

The sides show that we have an equilateral triangle

An equilateral triangle is a triangle in which all three sides are of equal length. Since all three sides are equal, all three angles are also equal and measure 60 degrees each.

We know that;

12x - 22 = 10x - 6

Collect like terms;

12x - 10x = -6 + 22

2x = 16

x = 8

Thus the sides of the triangle are;

12(8) - 22 = 74

10(8) - 6 = 74

7(8) + 18 = 74

In the second triangle;

4x - 25 = x + 14

4x - x= 14 + 25

Answer: 24 minutes and 30 seconds after the meeting as started

Step-by-step explanation:

110 minutes into 2 equal parts = 55 minutes in each section.

In the middle of 55 minutes = subtract the 10 minutes for a break from the 55 minutes that leaves you with 45 minutes. 24 minutes and 30 seconds before and after the 10 minute break.

Total session minutes - 110

Two equal parts of session: 55 minutes in each session

10 minute break in each session: 55-10 =45.

24 minutes and 30 seconds + 10 min break (in middle) + 24 minutes and 30 seconds

After 50 minutes the break will start.

The metting is 110 minutes long. According to the Question the metting have 'a'(only one) break of 10 minutes in between of two equal parts of metting.

so, duration of metting without the break=100 minutes

                                 duration of each part=50 minutes

It seems like the chat transitioned to a different topic. However, based on the search results, it appears that the query was related to solving distance problems using linear equations. One common application of linear equations is in distance problems, where you can create and solve linear equations to find the distance between two points or the rate of travel. Here's an example problem:

Joe drove from city A to city B, which are 120 miles apart. He drove part of the distance at 60 miles per hour (mph) and the rest at 40 mph. If the entire trip took three hours, how many miles did he drive at each speed?

To solve this problem, you can use a system of two linear equations. Let x be the number of miles driven at 60 mph, and y be the number of miles driven at 40 mph. Then you have:

x + y = 120 (total distance is 120 miles) x/60 + y/40 = 3 (total time is 3 hours)

To solve for x and y, you can multiply the second equation by 120 to eliminate fractions and then use the first equation to solve for one of the variables. For example:

x/60 + 3y/120 = 3 x/60 + y/40 = 3 2x/120 + 3y/120 = 3 x/60 + y/40 = 3 x/60 = 3 - y/40 x = 180 - 3y/2 (from the first equation)

Substitute the expression for x into the second equation and solve for y:

x/60 + y/40 = 3 (180 - 3y/2)/60 + y/40 = 3 3 - 3y/160 + y/40 = 3 3 - 3y/160 = 2.75 -3y/160 = -0.25 y = 20

Substitute y = 20 into the expression for x to get:

x = 180 - 3y/2 x = 120

Therefore, Joe drove 120 - 20 = 100 miles at 60 mph and 20 miles at 40 mph.

The coordinates of the point that corresponds to -5π/4 on the unit circle is (-1/√2, 1/√2).

Given that,

We have to find the coordinates of the point that corresponds to -5π/4 on the unit circle.

We know that any point on the unit circle can be defined as,

(cos θ, sin θ)

where θ is the angle formed with the X axis.

-5π/4 will be the point the corresponds to -225°.

Cos(-5π/4) = cos (5π/4)

                  = cos (π + π/4)

                  = -cos (π/4)

                  = -1/√2

sin (-5π/4) = -sin (5π/4)

                  = -sin (π + π/4)

                  = sin (π/4)

                  = 1/√2

If the sample size was increased, the 95% confidence interval would likely decrease. This is because a larger sample size typically leads to more precise estimates and less variability in the data, resulting in a narrower confidence interval.

Step-by-step explanation:

You want the perimeter and area of a figure consisting of a 4 × 11 rectangle with semicircles attached to each straight edge.

If you trace the perimeter of the figure, you see you are tracing the circumference of a circle 4 units in diameter and the circumference of a circle that is 11 units in diameter. The circumference of a circle is given by ...

  C = πd

so the total circumference is ...

  C1 +C2 = π(4) +π(11) = π(4+11) ≈ 47.12 . . . . units

The perimeter of the figure is about 47.12 units.

The area of two half-circles is the area of one whole circle of the same diameter. The area of a circle of diameter d is given by ...

  A = (π/4)d²

The total area of the circles of diameters 4 and 11 is ...

  A1 +A2 = (π/4)·4² +(π/4)·11² = (π/4)(4² +11²)

The area of the central rectangle is added to the areas of the semicircles. Its area is ...

  A = LW

  A = (11)(4)

The area of the entire figure is the sum of the circle areas and the rectangle area:

  total area = (π/4)(4² +11²) +(4)(11) ≈ 151.60 . . . . square units

The area of the figure is about 151.60 square units.

__

Additional comment

You usually see the formula for the area of a circle as ...

  A = πr²

Since r = d/2, we can express this using d as ...

  A = π(d/2)² = π(d²)/(2²) = (π/4)d²

You may notice that a square that circumscribes the circle will have a side length of d, and an area of d². The fraction π/4 tells you the fraction of that enclosing square that is covered by the circle. This fact can help you estimate areas and volumes of circles and cylinders.

Parallels lines:
y = 8x - 43

Perpendicular line:

y = [tex]\frac{-1}{8}[/tex]x - [tex]\frac{19}{8}[/tex]

Step-by-step explanation:

y = 8x -7

Parallel lines have the same slope.

The slope will be 8.  We will use the x from the point (5,-3) and the y from the point (5,-3) to find the y-intercept  (b)

y = mx + b  Substitute in -3 for y, 8 for m, and 5 for x.

-3 = 8(5) + b

-3 = 40 + b  Subtract 40 from both sides

-3 - 40 = 40 - 40 + b

-43 = b

Substitute in 8 for m and -43 for b to write the equation

y = mx + b

y = 8x - 43

Perpendicular slope are opposite reciprocals of each other, so the perpendicular slope is [tex]\frac{-1}{8}[/tex]

Substitute  [tex]\frac{-1}{8}[/tex] doe m, -3 for y and 5 for x.

y = mx + b

-3 = [tex]\frac{-1}{8}[/tex](5) + b

-3 = [tex]\frac{-5}{8}[/tex] + b   add [tex]\frac{5}{8}[/tex] from both sides

-3 +  [tex]\frac{5}{8}[/tex] = [tex]\frac{-5}{8}[/tex] +  [tex]\frac{5}{8}[/tex] + b

[tex]\frac{-24}{8}[/tex] + [tex]\frac{5}{8}[/tex] = b

[tex]\frac{-19}{8}[/tex] = b

Substitute [tex]\frac{-1}{8}[/tex] for m and [tex]\frac{-19}{8}[/tex] for b

y = mx + b

y = [tex]\frac{-1}{8}[/tex]x - [tex]\frac{19}{8}[/tex]

The velocity of the rock as a function of time is given by:

[tex]v(t) = 3 - 4.9exp(-2t/0.2) m/s[/tex]

where 4.9 is the value of mg in SI units.

The forces acting on the rock are the force due to gravity and the force due to air resistance. The force due to air resistance is given by 0.5v, where v is the velocity of the rock.

The force due to gravity is given by the mass of the rock (0.2 kg) times the acceleration due to gravity [tex](9.8 m/s^2)[/tex]. Using Newton's second law, we can set up the following differential equation:

[tex]m(dv/dt) = -mg - 0.5v[/tex]

where m is the mass of the rock, g is the acceleration due to gravity, and v is the velocity of the rock as a function of time t.

We can simplify this differential equation by dividing both sides by m:

[tex]dv/dt = (-g - 0.5v/m)v[/tex]

This is a separable differential equation, which we can solve using the separation of variables:

[tex](1/(-g - 0.5v/m)) dv = dt[/tex]

Integrating both sides gives:

[tex]-2ln(-g - 0.5v/m) = t + C[/tex]

where C is a constant of integration.

Solving for v gives:

[tex]v(t) = -0.5mg + C'exp(-2t/m)[/tex]

where C' = exp(C).

We can find the value of C' using the initial condition that the initial velocity of the rock is 3 m/s:

[tex]v(0) = -0.5mg + C' = 3[/tex]

[tex]C' = 0.5mg + 3[/tex]

Substituting this into the equation for v(t) gives:

[tex]v(t) = -0.5mg + (0.5mg + 3)exp(-2t/m)[/tex]

Therefore, the velocity of the rock as a function of time is given by:

[tex]v(t) = 3 - 4.9exp(-2t/0.2) m/s[/tex]

where 4.9 is the value of mg in SI units.

By the principle of mathematical induction, the statement holds for all positive integers n.

Using mathematical induction:

Base case:

For n=1, results into:

which is true.

Inductive step:

For some positive integer k, we have:

2+4+8+...+2^k = 2^(k+1) + 1 - 2

This implies the statement for n=k+1, i.e.,

2+4+8+...+2^k+2^(k+1) = 2^(k+2) + 1 - 2

From the left-hand side of the equation, we can rewrite it as:

2+4+8+...+2^k+2^(k+1) = (2+4+8+...+2^k) + 2^(k+1)

Applying the induction hypothesis, substitute the expression for 2+4+8+...+2^k:

2+4+8+...+2^k+2^(k+1) = (2^(k+1) + 1 - 2) + 2^(k+1)

Simplify:

2+4+8+...+2^k+2^(k+1) = 2^(k+2) - 1

Using the formula for the sum of a geometric series to simplify the right-hand side of the original statement:

2^(k+2) + 1 - 2 = 2^(k+2) - 1
