Please upload a picture of a piece of paper with the problem worked out, and draw the graph for extra points, there will be 6 of these, so go to my profile and find the rest, and do the same, for extra points.

Answer:

To find the number of smaller pieces that can be obtained, we need to divide the total length of the wood by the length of each smaller piece:

Number of pieces = Total length ÷ Length of each piece

Number of pieces = 7.2 m ÷ 0.12 m

Number of pieces = 60

Therefore, 60 smaller pieces can be obtained from the 7.2 m long piece of wood.

Answer:

60

Step-by-step explanation:

To determine how many smaller pieces can be obtained from a 7.2 m long piece of wood, we need to divide the total length of the wood by the length of each smaller piece.

Total length of wood = 7.2 m

Length of each smaller piece = 0.12 m

Number of smaller pieces = Total length of wood / Length of each smaller piece

Number of smaller pieces = 7.2 m / 0.12 m

Number of smaller pieces = 60

Therefore, 60 smaller pieces can be obtained from a 7.2 m long piece of wood, with each smaller piece being 0.12 m in length.

Answer:

y=f(x) = log7x

Just trust me

The graph best represents the function y = f(x) = 7x, an exponential function.

The graph represents the function y = 7x, which is an exponential function. In an exponential function, the variable x is the base, and the exponent is a constant, which in this case is 7. This means that the function grows rapidly as x increases, creating a steep curve on the graph.

The other two options, y = f(x) = log7x and y = f(x) = x7, are not represented by the given graph.

The function y = f(x) = log7x is a logarithmic function, which has a different shape on the graph, with a horizontal asymptote and the x-axis acting as its asymptote.

The function y = f(x) = x7 is a polynomial function, where x is raised to the power of 7, and it would have a different pattern on the graph compared to the exponential function shown.

Thus, the graph best represents the function y = f(x) = 7x, an exponential function.

The area of the sidewalk in square meters is 69π.

To find the area of the sidewalk, we need to subtract the area of the flower bed from the area of the outer circle formed by the sidewalk.

First, we need to find the area of the flower bed. We know that the diameter of the flower bed is 20 m, so the radius is half of that, which is 10 m. We can use the formula for the area of a circle, which is A = πr^2, where A is the area and r is the radius.

Area of flower bed = π(10m)^2 = 100π square meters

Next, we need to find the area of the outer circle formed by the sidewalk. Since the sidewalk is 3 m wide, the radius of the outer circle will be 10 + 3 = 13 m (10 m for the flower bed radius plus 3 m for the width of the sidewalk).

Area of outer circle = π(13m)^2 = 169π square meters

Finally, we can find the area of the sidewalk by subtracting the area of the flower bed from the area of the outer circle:

Area of sidewalk = Area of outer circle - Area of flower bed
Area of sidewalk = (169π) - (100π)
Area of sidewalk = 69π square meters

Therefore, the area of the sidewalk in square meters is 69π, or approximately 216.6 square meters (if we use 3.14 for π).

The total surface area of the television is 21,584 square centimeters.

To find the total surface area of the television, we need to calculate the area of all six sides and add them up.

The front and back sides have the same dimensions and area, so we can find the area of one and multiply it by two. The same goes for the left and right sides.

The area of the front/back sides is:

120 cm x 68 cm = 8160 sq cm

Multiplying by 2 gives us the total area of both front/back sides:

2 x 8160 sq cm = 16,320 sq cm

The area of the left/right sides is:

68 cm x 14 cm = 952 sq cm

Multiplying by 2 gives us the total area of both left/right sides:

2 x 952 sq cm = 1904 sq cm

The area of the top and bottom sides is:

120 cm x 14 cm = 1680 sq cm

Multiplying by 2 gives us the total area of both top/bottom sides:

2 x 1680 sq cm = 3360 sq cm

Adding up all six sides, we get:

16,320 sq cm + 1904 sq cm + 3360 sq cm = 21,584 sq cm

Therefore, the total surface area of the television is 21,584 square centimeters.

The function has a horizontal asymptote at y = 3. Other types of discontinuities can also occur in rational functions

A polynomial is a mathematical expression that consists of variables and coefficients, which are combined using arithmetic operations such as addition, subtraction, multiplication, and non-negative integer exponents.

A rational function can have a discontinuity at any point where the denominator of the function becomes zero since division by zero is undefined. These points are called "vertical asymptotes."

For example, consider the rational function f(x) = (x² - 1) / (x - 1). The denominator becomes zero when x = 1, which causes a vertical asymptote at x = 1. At x = 1, the function approaches positive infinity from the left-hand side and negative infinity from the right-hand side. This creates a "hole" or a "removable discontinuity" in the graph of the function.

Another type of discontinuity that can occur in a rational function is a "horizontal asymptote." This occurs when the degree of the numerator is less than the degree of the denominator. In this case, the function approaches a horizontal line (the horizontal asymptote) as x approaches infinity or negative infinity.

For example, consider the rational function f(x) = (3x² - 2x + 1) / (x² + 1). As x approaches infinity or negative infinity, the function approaches the horizontal line y = 3.

Therefore, the function has a horizontal asymptote at y = 3.

Other types of discontinuities can also occur in rational functions, such as "slant asymptotes" or "oscillating behavior," but these are less common and typically require more advanced techniques to identify.

The integer that represents a credit of $30 if zero represents the original balance is +30.

A credit represents an increase in funds, while a debit represents a decrease. In this case, a credit of $30 means that $30 has been added to the account, increasing the balance. Since zero represents the original balance, adding $30 results in a positive balance of $30, which is represented by the integer +30.

Therefore, +30 represents a credit of $30 if the original balance is zero. The reasoning behind this is that a credit increases the balance, so a positive integer is used to indicate the amount by which the balance has increased. In this case, it is an increase of $30, hence +30.

The probability of spinning fewer than four nines is 1,626,101,367 / 1073741824, which simplifies to approximately 1.514%.

To find the probability of spinning fewer than four nines, we need to first calculate the total number of possible outcomes. The spinner can land on any of the eight sections on the board, and it is spun 10 times. So, the total number of possible outcomes is 8^10, which is 1073741824.

Next, we need to calculate the number of outcomes where fewer than four nines are spun. We can do this by finding the number of outcomes with 0, 1, 2, or 3 nines, and adding them up.

To find the number of outcomes with 0 nines, we need to find the number of ways to choose from the non-nine sections on the board. There are 5 non-nine sections, and we need to choose 10 of them. This is a combination problem, and the number of outcomes is 252.

To find the number of outcomes with 1, 2, or 3 nines, we need to use a similar approach. We can use combinations to find the number of ways to choose the nines and the non-nines, and then multiply them together. The number of outcomes with 1 nine is 9 x 5^9, with 2 nines is 9 x 9 x 5^8, and with 3 nines is 9 x 9 x 9 x 5^7.

Adding up all these outcomes, we get 252 + 9 x 5^9 + 9 x 9 x 5^8 + 9 x 9 x 9 x 5^7 = 1,626,101,367.

So, the probability of spinning fewer than four nines is 1,626,101,367 / 1073741824, which simplifies to approximately 1.514%.

To convert to polar coordinates, we need to express x and y in terms of r and θ. We have:

x = r cos θ

y = r sin θ

Also, we need to change the limits of integration. The region of integration is the circle centered at the origin with radius 8, so we have:

-π/2 ≤ θ ≤ π/2 (for the upper half of the circle)

0 ≤ r ≤ 8

Now we can express the integrand in terms of r and θ:

[tex]x^2 + y^2 = r^2[/tex] (by Pythagoras)

[tex]20(x^2 + y^2) = 20r^2[/tex]

So the integral becomes:

∫-π/2π/2∫[tex]08r^3 cos^2 θ sin θ dr dθ[/tex]

We can simplify cos^2 θ sin θ using the identity cos^2 θ sin θ = (1/3)sin^3 θ, so we get:

∫-π/2π/2∫[tex]08r^3 (1/3)sin^3 θ dr dθ[/tex]

The integral with respect to r is easy to evaluate:

∫0^8r^3 dr = (1/4)8^4 = 2048

The integral with respect to θ is also easy to evaluate using the fact that sin^3 θ is an odd function:

∫-π/2π/2(1/3)[tex]sin^3[/tex] θ dθ = 0

Therefore, the value of the iterated integral is:

2048(0) = 0

The volume of the solid is zero. This makes sense because the integrand is an odd function of y (or sin θ) and the region of integration is symmetric with respect to the x-axis.

To find dx dy, we need to take the derivative of y with respect to x. Using the chain rule, we have:

dy/dx = d(Vx)/dx = V * d(x)/dx + x * d(V)/dx

Since we are given y = Vx, we can substitute and simplify:

dy/dx = y/x * d(V)/dx + V

Now we can plug in the given values: y = 8, dt/dx = 1.75. We also need to find V:

y = Vx, so V = y/x = 8/x

Now we can substitute and simplify again:

dy/dx = 8/x * d(V)/dx + 8/x

We need to find d(V)/dx. We know that t = f(x,V), so we can use the chain rule again:

dt/dx = df/dx + df/dV * dV/dx

Since t and V are independent, df/dV = 0. So we have:

dt/dx = df/dx + 0 * dV/dx

dt/dx = df/dx

We also know that dt/dx = 1.75. Therefore:

1.75 = df/dx

Now we can find d(V)/dx:

d(V)/dx = d/dx (y/x) = (dy/dx * x - y * dx/dx) / x^2

Since y = 8, we have:

d(V)/dx = (dy/dx * x - 8) / x^2

Substituting what we know, we get:

d(V)/dx = (8/x * 1.75 - 8) / x^2 = 8(1.75 - x) / x^3

Now we can substitute everything into the formula we derived earlier:

dy/dx = 8/x * d(V)/dx + 8/x

dy/dx = 8/x * (8(1.75 - x) / x^3) + 8/x

Simplifying, we get:

dy/dx = 14/x^2 - 1.75

Therefore, when y = 8 and dt/dx = 1.75, dx/dy = 1/(dy/dx) is:

dx/dy = 1 / (14/x^2 - 1.75) = x^2 / (14 - 1.75x^2)
Given y = √x, we first need to find dy/dx, the derivative of y with respect to x. Using the power rule, we can rewrite y = x^(1/2), and the derivative will be:

dy/dx = (1/2)x^(-1/2)

Now, we are given that y = 8, so we need to find the corresponding value of x:

8 = √x
64 = x

Next, we are given dt/dx = 1.75. We need to find dt/dy, which can be calculated by taking the reciprocal of dy/dx:

dt/dy = 1 / (dy/dx)

Now, we substitute x = 64 into the derivative:

dy/dx = (1/2)(64)^(-1/2) = (1/2)(8)^(-1) = 1/16

Finally, we can find dt/dy by taking the reciprocal of dy/dx:

dt/dy = 1 / (1/16) = 16

So, the value of dt/dy when y = 8 and dt/dx = 1.75 is 16.

The centroid of a quarter-circle with radius 6 is located at (4/3, 4/3) from the origin (as derived using calculus). Thus, the line of symmetry passes through the origin and (4/3, 4/3).

The equation of the line passing through two points (x1, y1) and (x2, y2) is given by:

(y - y1) / (x - x1) = (y2 - y1) / (x2 - x1)

The location of the point Kristin will add to represent the 13 bottles of water sold at 39 degrees Fahrenheit is the bottom left of the scatter plot.

A scatter plot represents the relationship between two variables. In this case, the temperature (independent variable) is plotted along the x-axis, while the number of bottles of water sold (dependent variable) is plotted along the y-axis. As the temperature increases, it is expected that more bottles of water would be sold.

The bottom left area of the scatter plot is where lower values of both temperature and the number of bottles sold would be found. Since 39 degrees Fahrenheit is relatively low and 13 bottles of water is a lower quantity, the point representing this data will be in the bottom left quadrant of the scatter plot.

2500 = a1 * r^4

a8 = a1 * r^(8-1)

312500 = a1 * r^7

We can divide the second equation by the first equation to eliminate a1:

312500 / 2500 = (a1 * r^7) / (a1 * r^4)

125 = r^3

Taking the cube root of both sides gives us:

r = 5

Now that we know the common ratio, we can use either of the two original equations to find the first term, a1. Using the first equation:

The score that marks the 11% of all scores is approximately 56.875 .

To find the score that marks the 11% of all scores, we need to use the standard normal distribution table, also known as the Z-table, since the given distribution is a normal distribution.

The first step is to find the Z-score that corresponds to the 11th percentile, which is given by: Z = invNorm(0.11) ≈ -1.225

Here, "invNorm" represents the inverse of the standard normal cumulative distribution function, which can be computed using statistical software or a calculator.

The second step is to use the Z-score formula to find the raw score that corresponds to this Z-score:Z = (X - μ) / σ

where X is the raw score we want to find, μ is the mean of the distribution, and σ is the standard deviation. Plugging in the values we have:

-1.225 = (X - 63) / 5

Solving for X, we get:

X = -1.225 * 5 + 63 = 56.875

Therefore, the score that marks the 11% of all scores is approximately 56.875
