2/3 divided by 5 please help me I'm bad at math (it needs to be a fraction)

Answer:

6

Step-by-step explanation:

A = π. r²

36π = π. r²

eliminate π, we get:

36=r²

r=√36

r = 6

Answer:

r = 6

Step-by-step explanation:

The area (A) of a circle is calculated as

A = πr² ( r is the radius )

Given A = 36π , then

πr² = 36π ( divide both sides by π )

r² = 36 ( take the square root of both sides )

r = \(\sqrt{36}\) = 6

Answer:

A

Step-by-step explanation:

The system of equations listed in answer A fits both of the criteria.

as x represents the number of 55-inch televisions and y fits the criteria of the number of 65-inch television, we can use the knowledge we have from the question that we can combine these two variables to get a total number of tv's.

As said in the question: "The first week they sold 44 TVs total" meaning that the combined total amount of TV's sold was 44, meaning x + y (which are just variables, not "known" amounts equates to 44.

x + y = 44

The second equation in the system represents the profits. Using the same knowledge from before, we don't know how many how many tv's of each were sold but we can use these variables to present that each 55-inch tv is worth $349 and each 65-inch tv is worth $469.

349x+469y = 17,516 represents this perfectly, thus making A our answer

The income a person must make to be in the highest income bracket $4420.09 using standard deviation

What is standard deviation?
The standard deviation is a statistician's way of gauging how much a group of numbers can vary or be dispersed. The values tend to be close to the set's mean when the standard deviation is low, while the values are dispersed over a larger range when the standard deviation is high.

As per the question,  

mean = u = $3398

standard deviation = σ = $571

Using standard normal

P(Z > z) = 3.67%

1 - P(Z < z) = 0.0367

P(Z < z) = 1 - 0.0367

P(Z < 1.79) = 0.9633

z = 1.79

Using z-score formula,

x = z * σ + u

x = 1.79 * 571 + 3398

= 4420.09

Hence the total income is  $4420.09 using standard deviation.

Answer:

The thickness of the new dirt cover is 0.144 yards.

Step-by-step explanation:

Dimension of garden = 25 feet by 25 feet.

Volume of soil bought = 10 cubic yards

Volume = length x width x height

But,

1 foot = 0.333333 yard

So that,

25 feet = 25 x 0.333333

            = 8.33333 yards

The new dimension of the garden = 8.33333 yards by 8.33333  yards.

Let the thickness of the new dirt cover be represented by h.

Thus,

Volume = 8.33333 x 8.33333 x h

10 = 69.44439 x h

h = \(\frac{10}{69.44439}\)

  = 0.144

h = 0.144 yards

The thickness of the new dirt cover is 0.144 yards.

Answer:

a= v2-v1/t 50-0/5 = 10m/s

The correct answer is option  A: The random variable is discrete. A decibel is a unit of measure used to quantify the loudness or intensity of sound.

From 0 dB (the quietest level of sound) to 140 dB (the loudest level of sound), it is measured on a logarithmic scale (the highest level of sound).

The decibel level of a siren is normally between 110 and 120 dB, which is regarded to be within or close to the threshold of human hearing.

The decibel level of a siren is measured on a logarithmic scale, making it a discrete variable. This indicates that it is measured in whole numbers rather than fractions of a decibel.

For instance, a siren's decibel level can be 110 dB, 111 dB, 112 dB, etc., but it cannot be 110.5 dB or 111.5 dB. Therefore, the decibel level of a siren is a discrete variable.

Answer:

f(x)=f(4)-\(2^{x-1}\)

Step-by-step explanation:

The rate of change can be found out by dividing -8 by 4, 16 by -8, or -32 by 16.

The rate of change is -2

To find f(1), I will find the first value in the sequence, which is 4.

Apply these values to the explicit formula:

The value of the expression, \(\sqrt[90]{100}\) is given using logarithms as approximately 1.0525

The logarithm of a number, a, is the value, y, to which a base number, b, is to be raised to give the number x as follows;

\(log_ba = y\)

\(\therefore b^y = a\)

The evaluation of the the expression, \(\sqrt[90]{100}\), can be performed as follows;

Let x represent the value, \(\sqrt[90]{100}\), we have;

x =  \(\sqrt[90]{100}\)

\(\sqrt[90]{100} = 100^{\frac{1}{90} }\), which gives;

\(x= 100^{\frac{1}{90} }\)

Taking the logarithm to base 10 of both sides gives;

\(log_{10}x = log_{10}100^{\frac{1}{90} }\)

\(log_{10}x = log_{10}100^{\frac{1}{90} } = \dfrac{1}{90}\cdot log_{10}100^\)

\(log_{10}x = \dfrac{1}{90}\cdot log_{10}100=\dfrac{1}{90}\times 2 = \dfrac{1}{45}\)

\(x = antilog\left(\dfrac{1}{45} \right)\approx 1.0525\)

Therefore; x =  \(\sqrt[90]{100}\) ≈ 1.0525

If a positive association exists between two quantitative variables, the slope will be positive.

Why the slope will be positive?

A quantitative variable is a variable that takes on numerical values that are either counted or measured. The weight of a newborn baby, the height of a tree, the number of questions answered correctly on a quiz, and the number of students in a classroom are all examples of quantitative variables.

A positive association exists when two variables increase in tandem with one another. When one variable increases, the other variable also increases. Alternatively, when one variable decreases, the other variable also decreases.

A linear relationship between two variables is defined by the slope of the line connecting them. The slope of the line can be found by calculating the change in y (the dependent variable) divided by the change in x (the independent variable).The slope of a line will be positive if there is a positive association between two quantitative variables. A negative association will be indicated by a negative slope. If there is no association, the slope will be zero, and if it cannot be determined, we will not know if the slope will be positive or negative.

The equation of the tangent line to the graph of f(x) at the point (-1, 25) is y = 32x + 57.

Finding the equation of a tangent line to a graph is an important skill in calculus. It allows us to determine the instantaneous rate of change at a specific point on the graph. In this case, we are asked to find the equation of the tangent line to the graph of the function f(x) = (-4x² + 4x + 3)(x² - 4) at the point (-1, 25).

To find the equation of the tangent line, we need to determine the slope of the tangent line at the given point (-1, 25) and then use the point-slope form of a line to write the equation.

Step 1: Find the derivative of the function f(x) with respect to x. The derivative will give us the slope of the tangent line at any given point.

Let's first expand the given function f(x):

f(x) = (-4x² + 4x + 3)(x² - 4)

     = -4x⁴ + 4x³ - 16x² + 4x² - 4x - 12

Now, we differentiate f(x) with respect to x:

f'(x) = d/dx(-4x⁴ + 4x³ - 16x² + 4x² - 4x - 12)

      = -16x³ + 12x² - 32x + 4

Step 2: Substitute x = -1 into f'(x) to find the slope of the tangent line at x = -1.

f'(-1) = -16(-1)³ + 12(-1)² - 32(-1) + 4

      = -16 + 12 + 32 + 4

      = 32

Therefore, the slope of the tangent line at the point (-1, 25) is 32.

Step 3: Use the point-slope form of a line to write the equation of the tangent line.

The point-slope form of a line is given by y - y₁ = m(x - x₁), where (x₁, y₁) is a point on the line and m is the slope.

Substituting the values (-1, 25) and m = 32 into the equation, we get:

y - 25 = 32(x - (-1))

y - 25 = 32(x + 1)

Expanding the equation, we have:

y - 25 = 32x + 32

To obtain the equation in slope-intercept form (y = mx + b), we isolate y:

y = 32x + 32 + 25

y = 32x + 57

Therefore, the equation of the tangent line to the graph of f(x) at the point (-1, 25) is y = 32x + 57.

In conclusion, by finding the derivative of the function and evaluating it at the given point, we determined the slope of the tangent line. Using the point-slope form, we obtained the equation of the tangent line as y = 32x + 57.

-1              -1                       -

0             -0.5             -0.5 - (-1) = 0.5

1                 0               0 - (-0.5) = 0.5

2              0.5              0.5 - 0 = 0.5

3                1                 1 - 0.5 = 0.5

There is a common difference (d) = 0.5

Therefore, table represents a linear function.

Let the equation of the linear function is,

y = mx + b

Here, m = Slope and b = y-intercept

Since, slope of a line passing through two points \((x_1,y_1)\) and \((x_2,y_2)\) will be,

m = \(\frac{y_2-y_1}{x_2-x_1}\)

Two points from the given table are (-1, -1) and (0, -0.5)

m = \(\frac{-0.5-(-1)}{0-(-1)}\)

m = 0.5

Y-intercept of the line 'b' = -0.5 (Value of y at x = 0)

Therefore, equation of the line will be,

y = 0.5x - 0.5

What is perimeter?

A perimeter is a closed path that encloses, surrounds, or delimits a one-dimensional length, a two-dimensional shape, or both. The circumference of a circle or an ellipse is its perimeter. There are numerous practical uses for calculating the perimeter.

Given: The perimeter of a rectangular field is 362 yards.

The width of the field is 82 yards.

We have to find the length of the rectangle.

Let x is the length of the rectangle and y is the width of the rectangle.

By the definition of perimeter,

x + x + y + y = 362

      2x + 2y = 362

Plug y = 82

 2x + 2(82) = 362

    2x + 164 = 362

             2x  = 362 - 164

              2x = 198

                x = 99

Therefore, the length of the rectangle is 99 yards.
