The constant of proportionality, o slope, is the coefficient multiplying [tex]x[/tex] in the equation. The y-intercept is the constant term added at the end, with no variable:

[tex]y=mx+b[/tex]

Answer:

1. m = -3

2. b = 2

Step-by-step explanation:

Using slope-form equation, y = mx+b where m is the gradient of the line and b is the y-intercept. So in the equation, y = -3x + 2, m is -3 and b is 2.

[tex]\huge \boxed{\boxed{\textbf{See attached graph}}}[/tex]

Adding a constant [+6] to [f(x)] shifts the entire graph of [f(x)] vertically up by 6 units. This means that every y-value of the original function will increase by 6.

We need to identify a few key points on the original graph of f(x). For example the [f(x)] given has points:

[tex]\boxed{\begin{minipage}{7 cm}Applying Transformation \\ \\(0,-2) \xrightarrow[\text{}]{\text{y+6 = -2+6}} (0,4) \\ \\(1,2) \xrightarrow[\text{}]{\text{y+6 = 2+6}} (1,8) \\ \\(2, 6) \xrightarrow[\text{}]{\text{y+6 = 6+6}} (2,12)\end{minipage}}[/tex]

We can shift each point on the original graph 6 units up. For each point  [(x, y)] on [f(x)], plot the new point at [(x, y + 6)]

After plotting the transformed points, connect them to form the new line, which will be parallel to the original line and shifted 6 units up.

Answer:

D. 5.0

Step-by-step explanation:

When the ball hit the ground, height h =0

So,

h= -4.9t² + 25t

0 = -4.9t² +25t

t(-4.9t+25)=0

t=0 (start) , and -4.9t+25=0,   4.9t =25,    t≈5.1(finish)

the number of adult tickets sold

\text{\textquotedblleft at most 96 people"}\rightarrow \text{96 or fewer tickets}

“at most 96 people"→96 or fewer tickets

Use a \le≤ symbol

Therefore the total number of tickets sold, s+as+a, must be less than or equal to 96:96:

s+a\le 96

s+a≤96

\text{\textquotedblleft no less than \$990"}\rightarrow \text{\$990 or more}

“no less than $990"→$990 or more

Use a \ge≥ symbol

Each student ticket sells for $7.50, so ss student tickets will bring in 7.50s7.50s dollars. Each adult ticket sells for $12.50, so aa adult tickets will bring in 12.50a12.50a dollars. Therefore, the total amount of revenue 7.50s+12.50a7.50s+12.50a must be greater than or equal to \$990:$990:

7.50s+12.50a\ge 990

Answer:

-3

Step-by-step explanation:

3*-3=-9

-9-20=-29

To find the number, we can represent it as 'x' and create an equation. By isolating 'x' using addition and division, we find that the number is -3.

To solve this problem, let's represent the number as 'x'. The product of 3 and the number can be written as 3x. According to the problem, 20 less than 3x is equal to -29.

We can write this as: 3x - 20 = -29. To find the value of x, we need to isolate x. Adding 20 to both sides of the equation, we get: 3x = -9.

Finally, dividing both sides by 3, we find that the number is x = -3.

Answer:

W =1 1/4Step-by-step explanation:

Let W = what

W - 1/2 = 3/4

Add 1/2 to each side

W -1/2 +1/2 = 3/4+1/2

W = 3/4+1/2

Getting a common denominator of 4

W =3/4+1/2*2/2

W =3/4 +2/4

W = 5/4

Changing to a mixed number

W = 4/4 +1/4

W = 1 +1/4

W =1 1/4

To solve the question 'What minus 1/2 equals 3/4', we set up the equation X - 1/2 = 3/4. We then solve for X by adding 1/2 (equivalent to 2/4) to both sides, resulting in X = 5/4 or X = 1 1/4.

To solve the equation What minus 1/2 equals 3/4, you are basically looking for a number that when subtracted by 1/2 gives 3/4. To find this, we can use the basics of algebra.

Let's let the 'What' variable be X. So the equation becomes: X - 1/2 = 3/4. To solve for X, you would add 1/2 to both sides of the equation. The result is:

X = 3/4 + 1/2.

These are both fractions so we add them according to the rules of adding fractions. Finding a common denominator for the fractions, in this case, 4, we rewrite 1/2 as 2/4. The equation now reads X = 3/4 + 2/4.

Adding them gives us X = 5/4, or, written as a mixed fraction, X = 1 1/4.

Answer:

16.7%

Step-by-step explanation:

The first thing is to mention that they are two independent events, therefore the final probability is the multiplication of the two.

First event, select shirt. In total there are 4 and you must choose one of them, therefore the probability is:

1/4

Second event, select the pants. In total there are 3 and you must choose one of them, but there are two blue types, therefore any of the two is worth what means that the probability is:

2/3

The final probability:

P = 1/4 * 2/3

P = 0.167

Which means that the probability of choosing a white shirt and a blue pant (light or dark) is 16.7%

Answer:

14 days

Step-by-step explanation:

The half life of a substance is the time required until the object has only half of the inicial mass.

So, to find the inicial mass of the object, we use t = 0 in the equation A(t):

A(0) = 600*e^0 = 600

Half of this mass is 300, so we can use A(t) = 300 and then find the time:

300 = 600e^-0.05t

e^-0.05t = 0.5

ln(e^-0.05t) = ln(0.5)

-0.05t = -0.6931

t = 13.862 days

Rounding to nearest day, we have that t = 14 days

The calculated half-life is approximately 14 days.

To find the half-life of the substance decaying according to the function A(t) = 600[tex]e^{-0.05t}[/tex], we start by utilizing the definition of half-life. The half-life (t1/2) is the time required for the amount of the substance to reduce to half its initial quantity.

Given:

1. At half-life, A(t1/2) = A0 / 2, which means:

600 / 2 = 600[tex]e^{-0.05(t1/2)}[/tex]

2. Simplifying this equation:

300 =  600[tex]e^{-0.05(t1/2)}[/tex]

0.5 =  [tex]e^{-0.05(t1/2)}[/tex]

3. Taking the natural logarithm on both sides gives:

ln(0.5) = -0.05t1/2

ln(0.5) ≈ -0.693

So,

-0.693 = -0.05t1/2

t1/2 = 0.693 / 0.05 ≈ 13.86 days

Rounding to the nearest day, the half-life is approximately 14 days.

The question does not provide sufficient information to work out the perimeter of the track based on the given area. More information or clarification is necessary.

The subject of the question is unclear. Specifically, the mention of a 'track' and its 'perimeter' suggest a geometry-related question but there isn't enough information. Normally, if the track was a rectangle and you know the area as 4000 square meters, you'd need at least one side length to determine the other side and compute the perimeter. The mention of pi, however, indicates a possible circular track that wouldn't fit the context of a rectangular area.

In basic terms, a population is the total number of individuals, animals, items, observation, data, etc. So the sample, in other words, is a portion, part, or fraction of the whole group, and acts as a subset of the population. Samples are used in a variety of settings where research is conducted.

The base of the ladder needs to be positioned approximately 27.3 feet away from the wall.

Let's consider the ladder as the hypotenuse of a right triangle, where one leg represents the distance from the building (let's call it 'x'), and the other leg is the height of the window above the ground (10 feet). The angle between the ground and the ladder is given as 68°.

We can use the tangent function, which is defined as the ratio of the opposite side (height of the window) to the adjacent side (distance from the building):

tan(θ) = Opposite / Adjacent

In this case, tan(68°) = 10 feet / x

To find 'x,' we can rearrange the equation:

x = 10 feet / tan(68°)

Now, we can plug the values into a calculator to get the answer:

x ≈ 27.3 feet

Given:

A circle with a radius of 5 cm sits inside a 11 cm x 11 cm rectangle.

Question asked:

What is the area of the shaded region as shown in the figure ?

Solution:

First of all calculate area of circle and then area of rectangle:-

[tex]Area\ of\ cirle=\pi r^{2}[/tex]

                      [tex]= =\frac{22}{7} \times5\times5\\ \\ =\frac{550}{7}\\ \\=78.571[/tex]

As here length an width both are 11 cm, we can say that this is a square.

[tex]Area\ of\ square=(Side)^{2}[/tex]

                          = [tex]=11\times11=121\ cm^{2}[/tex]

Now, area of shaded region = Area of square - Area of circle

                                               = 121 - 78.571 = 42.429 [tex]cm^{2}[/tex]
