Step-by-step explanation:

The ball hits the ground when h=0.

[tex]0=154-10t-16t^{2}[/tex]

Solve for t. You can use the quadratic formula.

[tex]t=\frac{-(-10)+-\sqrt{10^{2}(-16\cdot154) } }{2(-16)}[/tex]

[tex]t=\frac{5+-\sqrt{2489} }{16} \\t=-3.43 t=2.81[/tex]

Time cannot be negative.  So, the answer is t=2.81 seconds.

The exponential decay model for this situation is P(t) = 200,000 * (1 - 0.03)^t

Suppose the value of which a thing is expressed in percentage is "a'

Suppose the percent that considered thing is of "a" is b%

Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).

We need to Write the percent as a fraction in simplest form

16.24%

So, we can rewrite it as;

16.24 / 100

16 and 24/100 or 16 6/25

So the percent as a fraction is 16 6/25

We are given that;

Population in 1992=200000

Time=6years

Rate=3%

To write an exponential decay model to represent this situation, we can use the formula:

P(t) = P * (1 - r)ᵗ

where P(t) is the population after t years, P is the initial population, r is the annual rate of decline as a decimal, and t is the number of years. In this case, the initial population P is 200,000, the annual rate of decline r is 0.03 (since the population declines by 3% each year), and t is the number of years from 1992, so t = 0 corresponds to 1992 and t = 6 corresponds to 1998.

P(t) = 200,000 * (1 - 0.03)^t

where t is the number of years from 1992 to 1998.

Therefore, by the given percent answer will be P(t) = 200,000 x (1 - 0.03)^t

Distance between both factories is 1543 m

In Trigonometry, the law of Cosines, also known as Cosine Rule or Cosine Formula basically relates the length of the triangle to the cosines of one of its angles. It states that, if the length of two sides and the angle between them is known for a triangle, then we can determine the length of the third side. It is given by:

c² = a² + b² – 2ab cosγ

Given,

A man hears the two blasts exactly 6.1 seconds and 2.7 seconds from two factories.

Angle between line of sight γ = 42.4°

Speed of sound = 344m/sec

Distance of factory A from man (a)

6.1 × 344 = 2098.4 m

Distance of factory B from man (b)

2.7 * 344 = 928.8 m

The side opposite the angle between his lines of sight will be the distance between the factories.

Using cosine law

c² = a² + b² – 2ab cos γ, where

c = distance between the factories

c² = 2098.4² + 928.8² – 2(2098.4)(928.8) cos 42.4°

c = √(2098.4² + 928.8² – 2(2098.4)(928.8) cos 42.4°)

c = √(4403282.56 + 862669.44 - 3897987.84(0.74))

c = √(5265952 - 2884511)

c = √2381441

c = 1543.19 m

  ≈ 1543 m

The point that would be included in the region shaded to show the half-plane greater than the line is the point that lies above the line.

In order to determine which point is included in the region shaded to show the half-plane greater than the line, we can use the following steps:
1. Identify the equation of the line.
2. Plug in the x and y values of the point into the equation of the line.
3. If the result is greater than the constant term in the equation of the line, then the point is included in the region shaded to show the half-plane greater than the line.

For example, if the equation of the line is y = 2x + 1, and the point is (2,5), we can plug in the x and y values into the equation:
5 = 2(2) + 1
5 = 5

Since the result is equal to the constant term in the equation of the line, the point (2,5) is included in the region shaded to show the half-plane greater than the line.

Comparing the two probabilities, we can see that the probability of any particular letter being called first (1/5) is five times greater than the probability of any particular number being called first (1/75). This is because there are five letters and only one number will be called first.

Viet's description of the probability of each number being called first can be determined as follows. There are 75 numbers in the set, and each number has an equal chance of being called first. Therefore, the probability of any particular number being called first is 1/75.

Quinn's description of the probability of any particular letter being called first can be determined as follows. There are five letters in the set, and each letter has 15 numbers associated with it. Therefore, the probability of any particular letter being called first is 15/75 or 1/5.

Comparing the probabilities, we can see that the probability of any particular letter being called first is greater than the probability of any particular number being called first. This is because there are fewer letters (5) than numbers (75), so the probability of selecting a particular letter is higher than the probability of selecting a particular number.

Therefore, Quinn's probability of any particular letter being called first is greater than Viet's probability of any particular number being called first.

To find the coordinates of point R after the reflection and translation, we would need to know its original coordinates in the figure QRST. Then we could apply the above rules to get its new coordinates.

What are coordinates ?

Coordinates are numerical values that specify the position or location of a point in a given space. In mathematics, coordinates are often expressed as ordered pairs or triplets of numbers, which correspond to the distances of the point from a set of fixed reference points or axes.

Without seeing the figure QRST, it is not possible to give the exact coordinates for point R after the reflection and translation. However, we can use some general knowledge about the effects of reflection and translation on the coordinates of a point.

When a figure is reflected across the x-axis, the x-coordinates of all its points remain the same, but the y-coordinates are negated. That is, if a point has coordinates (x, y) before the reflection, its coordinates after the reflection will be (x, -y).

When a figure is translated down by 3 units, the y-coordinates of all its points are decreased by 3. That is, if a point has coordinates (x, y) before the translation, its coordinates after the translation will be (x, y - 3).

Therefore, to find the coordinates of point R after the reflection and translation, we would need to know its original coordinates in the figure QRST. Then we could apply the above rules to get its new coordinates.

If the length and width of the pen are both whole numbers the possible perimeters for the pen are 98, 52, 38, 32, and 28.

To find the possible perimeters of the pen, we first need to find all the possible length and width pairs that would give us an area of 48 square feet. Since the length and width are whole numbers, we can start by listing out all the factors of 48:

1, 2, 3, 4, 6, 8, 12, 16, 24, 48

Each of these factors represents a possible length or width of the pen, and we can find the other dimension by dividing the area (48) by the first dimension. For example, if the first dimension is 1, then the other dimension is 48/1 = 48. However, we need to make sure that the second dimension is also a whole number.

Using this method, we can find all the possible length and width pairs:

1 x 48, 2 x 24, 3 x 16, 4 x 12, 6 x 8

Now we can calculate the perimeter for each of these pairs. The perimeter is the sum of the lengths of all four sides of the pen. Since the length and width are the same for a square pen, we can use the formula:

perimeter = 2(length + width)

For each pair, we can plug in the values for length and width to get the perimeter:

1 x 48: perimeter = 2(1 + 48) = 98

2 x 24: perimeter = 2(2 + 24) = 52

3 x 16: perimeter = 2(3 + 16) = 38

4 x 12: perimeter = 2(4 + 12) = 32

6 x 8: perimeter = 2(6 + 8) = 28

1 yard = 36 inches (since 1 yard = 3 feet and 1 foot = 12 inches)

So, 8 yards = 8 x 36 = 288 inches.

To find out how many presents can be wrapped with 288 inches of ribbon, we divide the total length of ribbon by the length needed for one present:

Number of presents = Total length of ribbon ÷ Length of ribbon needed for one present

Number of presents = 288 ÷ 9

Number of presents = 32

=> 2x + $1.80

Given that we know the final price, including tax, was $23.40, we can create the following equation:

=> 2x + $1.80 = $23.40

By deducting $1.80 from each half, we arrive at:

After 5 of the students who didn't wear glasses now do, the number of students who don't wear glasses becomes 5x - 5.

So, the new ratio of students who wear glasses to those who don't wear glasses is:

In mathematics, a combination of quantities usually means taking a group of items or values and selecting some of them without regard to their order. A combination is different from a permutation in that order does not matter in a combination, whereas it does matter in a permutation.

For example, if you have three objects labeled A, B, and C, then the possible combinations of two objects are AB, AC, and BC. These combinations are different from the permutations of two objects, which include AB and BA, AC and CA, and BC and CB.

Combinations are often used in probability, statistics, and combinatorics to calculate the number of ways that objects or values can be selected from a set, without regard to their order.

The situation in which the quantities combine to make 0 is:

The product  is less than 35.

To analyze this problem without calculating, we can look at the factors involved in the product. The first factor is 7, and the second factor is 5(3)/(4).

The second factor, 5(3)/(4), is less than 5 because it is the product of 5 and a fraction less than 1.

When we multiply 7 by a number less than 5, the result will be less than 35.

Therefore, the product of 7 and 5(3)/(4) is less than 35.

Step-by-step explanation:

it is a quadrilateral.

the sum of all angles in a quadrilateral is always 360°.

so,

360 = x + x + 2x + 7 + 2x + 5 = 6x + 12

348 = 6x

x = 348/6 = 58°

that's it.

The value of x and y in the line segment are 6 and 6.5 units repsectively.

The lines are three parallel lines cut by two transversal lines. The transversal lines that cut across the parallel lines have same length at intervals .

Using the information in the diagram let's find the value of x and y in the diagram.

Therefore,

2x + 1 = x + 7

2x - x = 7 - 1

x = 6 units

Therefore,

3y - 8 = y + 5

3y - y = 5 + 8

2y = 13

divide both sides by 2

y = 13 / 2

y = 6.5 units

Therefore,

x = 6 units

y = 6.5 units
