A geometric method is known as "stereographic projection" involves projecting a flat map of a sphere onto a three-dimensional surface with a point at its center.

This is one way to construct a sphere. The construction of geodesic domes, which gained popularity in the 1960s, is one example of an art and construction project that frequently makes use of this approach.

Using a solid material and carving it into the shape you want is another way to make a sphere. This can be accomplished using stone, clay, wood, and other materials. To produce a sphere with perfect symmetry, this method necessitates considerable skill and precision.

A third approach is to construct a sphere from numerous small, flat pieces. Paper or fabric can be used to accomplish this, with each piece being cut into a curved shape and glued together to form the sphere. Origami balls, for example, are a common decorative item made using this method.

The fourth year increase in salary is 4.5 percent.

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, Inka's starting annual salary was $55,600.

After her first year she received a 2% pay rise.

Now, 2% of 55,600

= 2/100 ×55,600

= 1112

So, salary of 2nd year is 55,600+1112=$56712

The next year she received a 3% pay rise.

Now, 3% of 56712

= 3/100 ×56712

= 1701.36

So, salary of 3rd year is 56712+1701.36=$58413.36

Last year she received an x% pay rise.

Now, x% of 58413.36+58413.36=61,042

x/100 ×58413.36=61,042-58413.36

584.1336x=2628.64

x=2628.64/584.1336

Answer:

  314 yd²

Step-by-step explanation:

You want the area of a circle that has a diameter of 20 yards.

The usual formula for the area of a circle is ...

  A = πr² . . . . . . where r is the radius

The radius of the circle is half the diameter, so is (1/2)(20 yd) = 10 yd.

Using this value in the formula, we find the area to be ...

  A = 3.14(10 yd)² = 314 yd²

The required solution of the given equation is x = -7.

"Multi-step equation" means an equation that requires more than one step to be solved.

"Like terms" refers to terms that have the same variables raised to the same powers. In this equation, there are no like terms, so no simplification of the equation is needed in that regard.

"Negative coefficients" refers to the fact that some of the coefficients in front of the variables in the equation are negative. For example, in this equation, the coefficient of x is -3, and the coefficient of -9 is also negative.

To solve this equation, you can simplify both sides by combining like terms:

-9 + x -3x = 5

-9 - 3x + x = 5

-9 - 2x = 5

Next, isolate the variable on one side of the equation by adding 9 to both sides:

-9 - 2x + 9 = 5 + 9

-2x = 14

Finally, divide both sides by -2 to find x:

(-2x) / -2 = 14 / -2

x = -7

So the solution is x = -7.

Answer:

i) 9

ii) 11

Step-by-step explanation:

First off, what is a "mode"?

The mode in a set of data is simply the most common answer/outcome;

Next, we need to understand the data;

In this case, families were asked about the number of cats they have;

The children answered 0, 1, 2 or 3;

8 families have 0 cats,

6 have 1,

10 have 2,

x have 3

So, the mode will be the most common answer to how many cats a family has;

As we can see from the data, the most common response was 2, i.e. 10 families have 2 cats, compared to only 8 with 0 cats and 6 with 1 cat;

If we know the mode is 2, the value of x has to be less than 10 as it is not the most common response;

The largest possible value will be 9.

If the mode is 3, then that means the x has to be the greatest number of responses;

Since the greatest number of responses to the other options is 10, then the number of responses to having 3 cats has to be at least 11;

The smallest possible value of x, if the mode is 3, will be 11.

The graph of f(x) = -0.1 |x| opens. The point (-100, -10) or (100, -10) is on the graph.

A relation between a collection of inputs and outputs is known as a function. A function is, to put it simply, a relationship between inputs in which each input is connected to precisely one output. Each function has a range, codomain, and domain. The usual way to refer to a function is as f(x), where x is the input. A function is typically represented as y = f. (x).

We know that the graph of the function f(x) = a|x| opens upwards if the value of a > 0 and it opens downwards for a< 0.

For the given function the value of a = -0.1 < 0.

So, the graph of f(x) opens downwards.

The coordinates of the graph are determined by substituting the value of y in the given function:

f(x) = -0.1 |x|

-10 = -0.1 |x|

x = -100 or x = 100

So, the two points are (-100, -10) or (100, -10).

Hence, the graph of f(x) = -0.1 |x| opens. The point (-100, -10) or (100, -10) is on the graph.

The  displacement x of the moving puck is; 0.43 meters

The displacement is defined as the change in position of an object. It is also called a vector quantity and has a direction and magnitude

The parameters given here are;

The polar coordinate initial velocity vector; U = 2.35 m/s, -22°

Final velocity vector; V = 6.42 m/s, +50°

This suggests to us that Cartesian x axis is parallel to angle 0° and y axis is parallel to +90°.

Change of velocity component parallel to +90° =  magnitude*sinθ,.

Thus, the change of that velocity

Δv = |V|sin(50) - |U|sin(-22)

Δv = 6.42sin(50) - 2.35sin(-22)

Δv = 4.9 - (-0.88)

Δv = +5.8 m/s

The equation for displacement is;

s = ut +1/2at^2

where acceleration time t = Δt = 0.215 s

initial velocity u = |U|sin(-22) = -0.88 m/s

acceleration parallel to u is a = Δv/Δt = +5.8/Δt

a = 5.8/t m/s^2

Thus;

s = -0.88t + ¹/₂* 5.8/t * t²

s = -0.88t +2.9t

16y+20=3y+21

13y=1

y=1/13

Answer:

y = 1/13

Step-by-step explanation:

 (4y + 5) : 3 = (y+7) :4

Product of extremes = (4y + 5) * 4

                                  = 4y *4 + 5*4

                                  = 16y + 20

Product of mean = 3*(y +7)

                            = 3*y + 3*7

                            = 3y + 21

Product of extremes = product of mean

          16y + 20 = 3y + 21

Subtract 20 from both sides,

                  16y = 3y + 21 - 20

                  16y = 3y + 1

Subtract 3y from both sides,

Answer:

The answer is the equation for the function describing the movement of the buoy:

f(x) = 5 * sin(2 * pi * x / 16) + 8

Step-by-step explanation:

To graph the function, we need to find an equation that describes the buoy's movement. Since the buoy bobs up and down 5 meters from the ocean's depth, we can use the sine function. The amplitude of the function is 5, since the buoy moves 5 meters from the normal ocean depth. The period of the function is 16 seconds, since it takes 16 seconds for the buoy to go from its highest point to its lowest point.

Using this information, we can write the equation for the function as:

f(x) = 5 * sin(2 * pi * x / 16) + 8

where x is the time in seconds.

The first point on the graph would be (0, 8), since at x = 0 the buoy is at normal ocean depth. The second point would be either a maximum or minimum value on the graph closest to x = 0, which can be found by finding the derivative of the function and setting it equal to zero.

The graph of the function would look like a wave that oscillates up and down, with a maximum value of 5 meters above the normal ocean depth and a minimum value of 3 meters below the normal ocean depth.

The solution to the system is (1.8, 7.6)

Step-by-step explanation:

To solve the system of linear equations by graphing, we need to plot the two lines on the same coordinate plane and find the point where they intersect, which will be the solution of the system.

Plot the lines:

y = 2/3x + 4 can be written as y = (2/3)x + 4, where the slope is 2/3 and the y-intercept is 4.

y = -x + 1 can be written as y = -x + 1, where the slope is -1 and the y-intercept is 1.

Find the intersection point:

To find the intersection point, we can substitute the x-value from one equation into the other equation. Let's use y = 2/3x + 4.

Substitute x from y = 2/3x + 4 into y = -x + 1:

-x + 1 = 2/3x + 4

Multiplying both sides by -3, we get:

3x - 3 = -2x - 12

Adding 2x to both sides, we get:

5x - 3 = -12

Adding 12 to both sides, we get:

5x = 9

Dividing both sides by 5, we get:

x = 1.8

Now that we have x, we can substitute it back into either equation to find the corresponding y-value. Let's use y = 2/3x + 4:

y = 2/3x + 4

y = 2/3 * 1.8 + 4

y = 3.6 + 4

y = 7.6

So the solution to the system is (1.8, 7.6), which is the point where the two lines intersect.
