Answer:

Step-by-step explanation:

(i) We know that more is the number of workers to do a job, less is the time taken to finish the job.

So, it is a case of inverse proportion.

(ii) Considering uniform speed, as the distance to be travelled increases, the time taken to cover it will also increase.

So, this is a case of direct variation.

(iii) Clearly, more is the area of cultivated land, more is the crop harvested.

So, it is a case of direct proportion.

(iv) We know that the more will be the speed of the vehicle, the distance will be covered in lesser time.

So, it is a case of inverse proportion.

(v) Clearly, more is the population, less is the area of land per person in a country.

So, it is a case of inverse proportion.

Answer:

Step-by-step explanation:

If y = 27 when x = 6, write the direct variation equation. If y = -7 when x = -14, write the direct variation equation and find y when x = 20. If x = 8 when y = 4, write the direct variation equation and find y when x = 5. y = 1/6x; If x = 36 when y = 6, find x when y = 42. If y = -16 when x = 4, find x when y = 20.

The inverses of the functions f(x) = x + 3 and f(x) = 2x + 4 are

y = x - 3 and x = (y + 4)/2.

First to be an inverse function that function needs to one to one function, meaning every different preimage must correspond to a different image.

We can obtain the inverse of a function by switching the variables x and y with their respective positions and solving for y in terms of x.

The first graph y = x + 3.

To find the inverse we'll solve for 'x'.

y = x + 3.

x = y - 3.

y = x - 3.

f⁻¹(x) = x - 3.

And,

y = 2x - 4.

2x = y + 4.

x = (y + 4)/2.

f⁻¹(x) = (x + 4)/2.

The graph of the function y = x + 3 is shifted 3 units up to y = x.

And the graph y = 2x - 4 is shifted 4 units down and is steeper than y = x.

The number of edges that the prism has is

When a plane intersects a prism, the shape formed is known as the cross section. The cross section of the prism will have the same form as the base if it is divided by a plane that runs horizontally and parallel to the base.

A prism is a 3-dimensional object with two congruent and parallel bases (which are polyggonal) connected by rectangular lateral faces. The number of edges of a prism is equal to the sum of the number of edges of the two bases and the number of lateral faces.

Each base of the prism has n edges, so the two bases together have 2n edges. The number of lateral faces of the prism is equal to the number of edges of one of its bases, so there are n lateral faces. Each lateral face has 4 edges, so the total number of edges of the lateral faces is 4n.

Therefore, the total number of edges of the prism is equal to the sum of the number of edges of the two bases (2n) and the number of lateral faces (4n), which is 2n + 4n = 6n.

In conclusion, the cross section of a prism is an n-sided polygon and the prism has n + 2 edges.

Step-by-step explanation:

The minimum number of degrees needed to carry the pentagon onto itself is 72.

A polygon having 5 sides and 5 angles are called a pentagon. Two terms, Penta and Gonia, both of which denote five angles, combine to form the word "pentagon." From end to end, the sides of a pentagon come together to form a shape. Consequently, there are five sides to a pentagon. The Pentagon has five sides, as far as we know.

Any polygon's outside angles now total 360 degrees. The minimal number of degrees needed to carry the pentagon inward is therefore = 360/5 = 72° if we rotate the pentagon counterclockwise around its center.

North and end up at the starting point. The unique geographic properties of the North Pole allow you to travel one mile south, then one mile east, and then one mile north, and end up back at thepo starting point. This property is unique to the North Pole and cannot be found anywhere else on the planet.

The only place on earth where you can travel one mile south, then one mile east, and then one mile north and end up at the starting point is the North Pole. This is because at the North Pole, all directions are north, and so no matter which direction you travel, you will always be moving away from the equator and towards the North Pole. Additionally, since all longitudes converge at the North Pole, traveling one mile in any direction will not change your latitude or longitude, meaning that you will end up back at the North Pole after traveling one mile south, then one mile east, and then one mile north.

At the North Pole, there is no concept of east and west as all lines of longitude converge at the pole. Hence, traveling one mile east or west will bring you back to the same location. The same applies to traveling one mile north or south as all directions at the North Pole are north.

It's important to note that the North Pole is a remote and inhospitable environment, with temperatures that remain below freezing throughout the year. As a result, there are no permanent settlements at the North Pole, and accessing the area requires specialized equipment and training.

The order of the graphs from the narrowest to the widest would be:

f(x) = ax², where |a| < |b| < |c|

f(x) = ax² + bx, where |a| < |b|

f(x) = ax² + bx + c, where |a| < |b| < |c|

Quadratic functions are mathematical functions that have a specific shape when plotted on a coordinate plane. The shape of a quadratic function is called a parabola and it opens either upwards or downwards.

When we compare the width of different parabolas, we can arrange them from the narrowest graph to the widest graph. The order is determined by the value of the coefficient in front of the x-squared term in the equation of the quadratic function. If the coefficient is positive, the parabola opens upwards, and if the coefficient is negative, the parabola opens downwards.

The width of the parabola can be calculated using the equation,

=> f(x) = ax² + bx + c,

where a is the coefficient in front of x-squared, b is the coefficient in front of x and c is the constant term. If the absolute value of the coefficient a is smaller, the graph will be narrower. If the absolute value of the coefficient a is larger, the graph will be wider.

There can be a maximum of 1183 bags, each containing 5 red cubes and 5 blue cubes.

Let x be the number of red cubes in each bag and y be the number of blue cubes in each bag. Then, the number of red cubes in all bags is 5915/x, and the number of blue cubes in all bags is 1715/y.

Since the number of cubes in each bag is the same and there will not be any cubes left over, we must have 5915/x = 1715/y = z, where z is the number of bags.

To find the greatest value of z, we need to find the greatest common factor (GCF) of 5915 and 1715. We can use the Euclidean algorithm:

5915 = 1715 × 3 + 720

1715 = 720 × 2 + 275

720 = 275 × 2 + 170

275 = 170 × 1 + 105

170 = 105 × 1 + 65

105 = 65 × 1 + 40

65 = 40 × 1 + 25

40 = 25 × 1 + 15

25 = 15 × 1 + 10

15 = 10 × 1 + 5

10 = 5 × 2 + 0

The GCF of 5915 and 1715 is 5, so each bag will contain 5 red cubes and 5 blue cubes. The number of bags is z = 5915/5 = 1183.

Therefore, there can be a maximum of 1183 bags, each containing 5 red cubes and 5 blue cubes.

The equation of the line passing through the given points  y=3-(x-3)

Linear equations help in representing the relationship between variables such as x, y, and z, and are expressed in exponents of one degree. In these linear equations, we use algebra, starting from the basics such as the addition and subtraction of algebraic expressions.

Given here: The point (3,3) and (4,2)

Using the two point form to construct the line that passes through both the points by following the standard equation. Point-slope is the general form y-y₁=m(x-x₁) for linear equations. It emphasizes the slope of the line and a point on the line (that is not the y-intercept).

Thus

y-3=2-3/4-3 (x-3)

y-3=-1(x-3)

y-3=-x+3

y+x=6

Answer:

$1,000 to the nearest dollar

Step-by-step explanation:

We can use the formula for compound interest to calculate the amount that Khalil would need to invest:

A = P * (1 + r/n)^(nt)

where A is the final amount, P is the initial amount (the amount invested), r is the interest rate as a decimal (6.6% = 0.066), n is the number of times compounded in a year (daily = 365), t is the number of years, and ^ is the exponent operator.

We want to find P, so we can rearrange the formula:

P = A / (1 + r/n)^(nt)

Plugging in the values:

P = $1,470 / (1 + 0.066/365)^(365 * 9)

Calculating this expression to the nearest dollar, we get P = $1,000.

So, Khalil would need to invest $1,000, to the nearest dollar, in order for the value of the account to reach $1,470 in 9 years
