What is the slope of the line that contains these points?

At the same rate as his 100-meter freestyle swim in the 2012 Olympics, Nathan Adrian could have completed one loop of a 25-meter pool in 11.88 seconds.

The idea of proportionality can be applied. The time it would take Nathan Adrian to complete one lap in a 25-meter pool is known to be 47.52 seconds for the 100-meter freestyle. Since the tempo is constant while the distance varies, we can establish a ratio:

100 meters / 47.52 seconds = 25 meters / x seconds

where x is the unknown time for one lap in the 25-meter pool.

To solve for x, we can cross-multiply:

100 meters * x seconds = 47.52 seconds * 25 meters

100x = 1188

Dividing both sides by 100, we get:

x = 11.88 seconds

Therefore, at the same rate as his 100-meter freestyle swim in the 2012 Olympics, Nathan Adrian could have completed one loop of a 25-meter pool in 11.88 seconds.

Answer: The equation used to find the value of x is 5x - 4 = 3x + 10. The value of x is determined to be 7.

Step-by-step explanation:

Four less than the product of a number (x) and 5 = 5x - 4

8 more than 2 added to 3 times the number = 3x + 2 + 8 = 3x + 10

Four less than the product of a number (x) and 5 is equal to 8 more than 2 added to 3 times the number => 5x - 4 = 3x + 10

                                                         5x - 3x = 10 + 4

                                                         2x = 14

                                                         x = 14/2

its decreasing so 2007 had 84.134 sheep farms so u gotta subract by a number to year 2080 and to get 79.300

the simplified form of the equation 6Y + 4 = 8 + 2Y + 2Y is Y = 2.

How to solve the question ?

To simplify the equation 6Y + 4 = 8 + 2Y + 2Y, we can combine like terms. Like terms are terms that have the same variable and the same exponent. In this case, we have two terms with Y as the variable, so we can combine them.

First, let's add the 2Y terms on the right side of the equation: 6Y + 4 = 8 + 4Y

Next, we can subtract 4Y from both sides of the equation to isolate the variable on one side: 6Y - 4Y + 4 = 8

Simplifying further, we can combine the Y terms: 2Y + 4 = 8

Finally, we can subtract 4 from both sides to isolate the variable: 2Y = 4

And we can solve for Y by dividing both sides by 2: Y = 2

Therefore, the simplified form of the equation 6Y + 4 = 8 + 2Y + 2Y is Y = 2.

In summary, to simplify an equation, we want to combine like terms and isolate the variable on one side of the equation. Once we have the variable on one side, we can solve for its value.

A straight line can be drawn through all the points, and the line passes through the origin.

When two variables are proportional, the ratio of their values remains constant. A graph of paired points that form a proportional relationship will show a straight line when plotted on a graph. The position of the line on the graph will depend on the constant of proportionality, which determines the slope of the line. If the constant of proportionality is positive, then the line will slope upwards, and if the constant of proportionality is negative, the line will slope downwards. If the line passes through the origin, it means that when one variable is zero, the other variable is also zero. This is referred to as an "origin-centered proportional relationship." In this case, the line passes through the point (0, 0), which is the origin. If the line does not pass through the origin, it means that there is a non-zero intercept, and that the relationship between the variables is not centered on the origin. In this case, the line will have a non-zero y-intercept, which is the value of the second variable when the first variable is zero.

In conclusion, the statement "a straight line can be drawn through all the points, and the line passes through the origin" best describes a graph of paired points that form a proportional relationship centered on the origin.

The equivalenet expression is 54\(n^{-11}\)

Any mathematical statement that includes numbers, variables, and an arithmetic operation between them is known as an expression or algebraic expression.

The way of representing huge numbers in terms of powers is known as an exponent. Exponent, then, is the number of times a number has been multiplied by itself.

To simplify the given expression, we need to apply the power of a power rule, which states that to raise a power to another power, we need to multiply the exponents.

Starting with:

(\(6n^-5\))(\(3n^-3\))²

We can simplify as follows:

(\(6n^-5\))(\(9n^-6\))

Now, we can use the product of powers rule, which states that when multiplying two powers with the same base, we add their exponents.

Therefore:

6 x 9 = 54

\(n^-5 * n^-6 = n^-11\)

A probability mass function (pmf) for a random variable X must satisfy the following two conditions:
1. f(x) ≥ 0 for all x
2. Σf(x) = 1

(a) f(x) = x/c
To find the constant c, we can use the second condition and sum over all possible values of x:
Σf(x) = Σ(x/c) = 1/c Σx = 1
Since we don't have a specified range for x, we cannot solve for c.

(b) f(x) = cx
Again, we can use the second condition to find the constant c:
Σf(x) = Σ(cx) = cΣx = 1
Without a specified range for x, we cannot solve for c.

(c) f(x) = c(1/4)^x
Using the second condition:
Σf(x) = Σ(c(1/4)^x) = cΣ(1/4)^x = 1
We can use the formula for an infinite geometric series to find the sum:
Σ(1/4)^x = 1/(1 - 1/4) = 4/3
So, c = 3/4

(d) f(x) = c(x + 1)^2
Using the second condition:
Σf(x) = Σ(c(x + 1)^2) = cΣ(x + 1)^2 = 1
Without a specified range for x, we cannot solve for c.

(e) f(x) = x/c
This is the same as part (a), so we cannot solve for c without a specified range for x.

(f) f(x) = c/(x+1)(x+2)
Using the hint, we can rewrite f(x) as:
f(x) = c(1/(x+1) - 1/(x+2))
Using the second condition:
Σf(x) = Σ(c(1/(x+1) - 1/(x+2))) = cΣ(1/(x+1) - 1/(x+2)) = 1
We can use the formula for a telescoping series to find the sum:
Σ(1/(x+1) - 1/(x+2)) = 1 - 1/(x+2)
As x approaches infinity, the sum approaches 1.
So, c = 1

To depict each pmf as a line graph, we would plot the values of f(x) on the y-axis and the values of x on the x-axis. However, without a specified range for x, we cannot create accurate graphs for parts (a), (b), (d), and (e). For part (c), the graph would be a decreasing exponential curve, with f(x) approaching 0 as x increases. For part (f), the graph would be a decreasing curve, with f(x) approaching 0 as x increases.

The weight's height at t=1.5 seconds is roughly 8.07 feet.

a. The equation for simple harmonic motion can be used to find a model that describes the motion of the weight:

Acos(wt + phi) + D = y(t)

A represents amplitude, w represents angular frequency, phi represents phase shift, and D represents vertical shift.

The amplitude A is equal to half the difference between these two heights because we know the weight oscillates between a minimum height of 4 feet and a maximum height of 10 feet:

A = (10 - 4)/2 = 3

The weight completes a full cycle in three seconds, hence the weight's angular frequency is:

T = 2pi/3 and w = 2pi

where T, or the period, denotes the length of time for one complete cycle.

We can set phi to 0 because the weight begins at the lowest height of 4 feet. Last but not least, the vertical shift D is just the average of the highest and lowest heights:

D = (10 + 4)/2 = 7

Combining everything, we obtain:

Y(t) equals 3cos((2pi/3)*t) + 7

b. By simply entering t=1.5 into our model, we can determine the height of the weight at t=1.5 seconds:

3cos((2pi/3)*1.5)*y(1.5) + 7 + 8.07

Hence, the weight's height at t=1.5 seconds is roughly 8.07 feet.

c. We can plot y(t) for t ranging from 0 to 6 seconds in order to graph the model for two periods (two full cycles). The graph is shown here:

In response to the stated question, we may state that Therefore, the cylinder volume of the tank is approximately 301 cubic feet.

A cylinder is a three-dimensional polyhedron made up of two congruent parallel circular bases but a curving surface linking the two bases. The bases of a cylinder are all equal to its axis, which is an artificial straight line across the centre of both bases. The volume of a cylinder is the composite of its base area and length. The volume of a cylinder is computed as V = r2h, where "V" represents the volumes, "r" represents the circle of the base, and "h" is the height of the cylinder. The formula to find the volume of a cylinder is:

\(V = \pir^2h\)

Where V is the volume, r is the radius, h is the height, and π is a constant value that approximates to 3.14.

\(V = 3.14 * 4^2 * 6\\V = 3.14 * 16 * 6\\V = 301.44\\V = 301 ft^3\)

Answer:

CAB is 37 degrees

Step-by-step explanation:

Answer:

Step-by-step explanation:

The Rational Zeroes Theorem states that if a polynomial equation has a rational solution (a solution that can be expressed as a fraction of two integers), then that rational solution must be of the form p/q, where p is a factor of the constant term (in this case 36) and q is a factor of the leading coefficient (in this case 4).

Step 1: Find the factors of 36. The factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, and 36.

Step 2: For each factor of 36, divide it by each factor of 4 to get a list of possible rational solutions.

Step 3: Test each of the possible rational solutions by plugging them into the polynomial equation and seeing if they make the equation equal to zero. If a solution makes the equation equal to zero, it is a root of the polynomial.

Step 4: Once you have found all of the roots of the polynomial, you can use them to write the polynomial in factored form.

Note: This method only works for polynomials with real coefficients and will only give you the real solutions of the equation. If the polynomial has complex solutions, you will need to use a different method to find them.

The systems of equations A. x – y = 1, –3x + 3y = 3 and E. x + y = 1, –4x + 2y = 7 have no solutions because the equations lead to contradictory statements.

The systems of equations that have no solutions are A. x – y = 1, –3x + 3y = 3 and E. x + y = 1, –4x + 2y = 7.
Let's analyze each system of equations to understand why they have no solutions:
A. x – y = 1, –3x + 3y = 3
To determine if this system has a solution, we can rearrange the first equation to solve for x:
x = y + 1
Then we substitute this expression for x into the second equation:
-3(y + 1) + 3y = 3
Simplifying, we get:
-3y - 3 + 3y = 3
-3 = 3
Since -3 does not equal 3, the system has no solution.
E. x + y = 1, –4x + 2y = 7
Again, we can rearrange the first equation to solve for x:
x = 1 - y
Substituting this expression for x into the second equation:
-4(1 - y) + 2y = 7
Simplifying, we get:
-4 + 4y + 2y = 7
6y - 4 = 7
6y = 11
y = 11/6
However, if we substitute this value of y back into the first equation, we get:
x + 11/6 = 1
x = 1 - 11/6
x = -5/6

Using the power reducing formulas the expression \(5cos^4(x) = 5(1 + cos(2x))^{2/4}\).

We can define higher powers of a trigonometric function in terms of lower powers of the same function using the power-reducing formulas, which are trigonometric identities. Higher powers of cosine can be expressed using this formula in terms of sine and cosine's initial powers. For the other trigonometric functions, such as sine and tangent, there are equivalent formulas. These formulas can be used to solve trigonometric equations and to simplify trigonometric expressions.

The given function is 5cos^4(x).

Now, the power reducing formulas are given by:

\(cos(2x) = cos^2(x) - sin^2(x) = 2cos^2(x) - 1\\cos^2(x) = (1 + cos(2x))/2\)

Substituting the value of second equation in 1 we have:

cos(2x) = 2(1 + cos(2x))/4 - 1

\(cos(2x) = (2cos^2(x) - 1) = cos^2(x) - sin^2(x)\)

Now we have:

\(cos^2(x) = (1 + cos(2x))/2\)

Thus,

\(cos^4(x) = (1 + cos(2x))/2)^2\)

To graph the function g(x) = 7x + 10, we shift the graph of f(x) = 7x vertically by adding a constant term of +10. This means every y-coordinate on the graph increases by 10 units. The slope of the line remains the same at 7. The resulting graph is a straight line passing through (0, 10) with a slope of 7.

To graph the function g(x) = 7x + 10, you need to make the following change to the graph of f(x) = 7x:
1. Translation: The graph of f(x) = 7x can be shifted vertically by adding a constant term to the equation. In this case, the constant term is +10.
Here's how you can do it step by step:
1. Start with the graph of f(x) = 7x, which is a straight line passing through the origin (0,0) with a slope of 7.
2. To shift the graph vertically, add the constant term +10 to the equation. Now, the equation becomes g(x) = 7x + 10.
3. The constant term of +10 means that every y-coordinate of the points on the graph will increase by 10 units. For example, the point (0,0) on the original graph will shift to (0,10) on the new graph.
4. Similarly, if you take any other point on the original graph, such as (1,7), the corresponding point on the new graph will be (1,17) since you add 10 to the y-coordinate.
5. Keep in mind that the slope of the line remains the same, as only the y-values are affected. So, the new graph will still have a slope of 7.
By making this change, you will have successfully graphed the function g(x) = 7x + 10.
