Answer:

For the economy as a whole, an improvement in technology shifts the production possibilities frontier outward. Production Possibility Frontier (PPF): An increase in technology that allows for greater output based upon the same inputs can be described as an outward shift of the PPF, as demonstrated in this figure.

Answer:

3,090 diamonds

Step-by-step explanation:

To get 10 shards, you need to spend 30 diamonds.

First thing we need to find, how many rounds you need to play to get 1,024 shards if in each round you win 10 shards?

1,024/10 = 102,4

But you can not play 102.4 rounds, you only can play whole numbers, so we need to round it to the next whole number (not the previous one, because in that case, we would get less than 1,024 shards)

Then you need to play 103 rounds.

And each round costs 30 diamonds, then the total number of diamonds that you need is:

103*30 diamonds = 3,090 diamonds

Step-by-step explanation:

As an example, iodine-131 is a radioisotope with a half-life of 8 days. It decays by beta particle emission into xenon-131. After eight days have passed, half of the atoms of any sample of iodine-131 will have decayed, and the sample will now be 50% iodine-131 and 50% xenon-131.

50 grams to 25 grams is one half-life. 25 grams to 12.5 grams is another half-life. So, for 50 grams to decay to 12.5 grams, two half-lives, which would take 36 days total, would need to pass. This means each half-life for element X is 18 days.

Answer:

After 8 hours or 2 half-lives, you will have 972 grams of ruthenium left.

Answer:

Think about it this way: The x axis goes from left to right, correct? So just try to visualize actually picking up the object and flipping it over that axis. So since one tip of the triangle is on the coordinate (1,1), after reflecting the shape that same tip would be on (1,-1). You understand?

Answer:

304.5 cm2

Step-by-step explanation:

Think imaginatively, we got two congruent triangles and two rectangles with different dimensions.

S.A. of 2 triangles = 2*( 1/2 x B x H)

= 2*( 1/2 x 10.5 x 14) = 147 cm2

Rectangle 1 = 5*17.5 = 87.5 cm2

Rectangle 2 = 5*14 = 70 cm2

Total = 147 + 87.5 + 70 = 304.5 cm2

[3] Vertical

     ➜ These angles are opposite angles created by two intersecting lines. They are also congruent, another quality of vertical angles.

[4] Neither

     ➜ While these angles are "opposite" of each other, they are incongruent angles. Since the angles are not adjacent or vertical, they are neither.

Answer: False

Step-by-step explanation: Let's review the idea of graphs.

For a graph to be linear, it must be a straight line.

To determine whether a given graph is a function,

we use the vertical line test.

The vertical line test tells us that if a vertical line is drawn on a graph,

and hits the graph in more than one place, the graph is not a function.

In fact, this definition tells us the only type of linear graph

that will fail the vertical line test, and that's a vertical line.

Any vertical line that we draw will be both linear and not a function.

One possible graph could be x = 2.

Any vertical line will fit this description.

Step-by-step explanation:

Similar shapes also maintain a constant proportion of sides. Therefore, we can set up the following equation:

\(\frac{31}{43}=\frac{\text{KI}}{8}\)

Solving, we get:

\(\text{KI}=\frac{8\cdot 31}{43}\approx \boxed{5.8}\)

Answer:

Step-by-step explanation:

If you divide, multiply, subtract, or add both sides of an equation by the same number, the end result of the equation will stay the same.

1) Divide both sides by 10.

\(\frac{10 (x + 3)}{10} = \frac{40}{10}\)

2) Simplify.

(x+3) = 4

3) Subtract by 3 on both sides.

x + 3 - 3 = 4 - 3

4) Simplify.

x = 1

The  derivative of the function ƒ (x) = 3/x+2 is: f'(x) = lim [h→0] [ -3/(x+2)² ]

Here, we have,

given that,

the equation is:

f(x) = 3/x+2

now, we have,

derivative of f(x) is:

f'(x) = lim [h→0]  [f(x+h) - f(x)/h]

substituting the values, we get,

f'(x) = lim [h→0]  [3/(x+h)+2 - 3/x+2 /h]

f'(x) = lim [h→0] [ -3h/h(x+2)(x+h+2) ]

f'(x) = lim [h→0] [ -3/(x+2)(x+h+2) ]

now, we have, (x+h+2)≈(x+2) [as, h→0]

so, we get,

f'(x) = lim [h→0] [ -3/(x+2)² ]

Answer:

  47.5 cm

Step-by-step explanation:

You want the height of a trapezoid with bases of lengths 135 cm and 105 cm, and an area of 5700 cm².

The formula for the area of a trapezoid is ...

  A = 1/2(b1 +b2)h

Filling in the given values, we have ...

  5700 = 1/2(135 +105)h

  5700 = 120h

  h = 5700/120 = 47.5

The height of the tabletop is 47.5 cm.

Answer:

Step-by-step explanation:

The point (-2, -10) does not lie on the line y = 3x - 3.

The formula for equation of line is expressed as;

y = mx + b

Where m is slope and b is y-intercept.

Given the equation of line in the question:

y = 3x - 3

To check if the point (-2, -10) lies on the line y = 3x - 3, we need to substitute the values of x and y into the equation and see if it is true.

y = 3x - 3

Plug in x = -2 and y = -10

-10 = 3(-2) - 3

Simplify

-10 = -6 - 3

-10 = -9

But we know that -10 ≠ -9, hence, this is not a true statement.

Therefore, the point does not lie on the line.

Answer:

the inequality is y>1/3x -3

Step-by-step explanation:

im built different

If triangle has a perimeter of 8x + 7. the first side of the triangle has a length of 4x, and the second side has a length of 2x − 3, the length of the third side of the triangle is 2x + 10.

To find the length of the third side of the triangle, we need to use the fact that the perimeter of a triangle is the sum of its three sides.

We are given that the perimeter of the triangle is 8x + 7, and we know the lengths of two sides: the first side has a length of 4x, and the second side has a length of 2x - 3. Let's use x as a common factor to simplify the expression for the perimeter:

Perimeter = 4x + (2x - 3) + (length of third side)

Perimeter = 6x - 3 + (length of third side)

8x + 7 = 6x - 3 + (length of third side)

Now we can solve for the length of the third side:

length of third side = 8x + 7 - 6x + 3

length of third side = 2x + 10

In general, when solving problems like this, it's important to remember that the perimeter of a triangle is the sum of its three sides, and to use algebraic equations to solve for unknown variables.
