Answer:

Below

Step-by-step explanation:

Standard form of a circle =     (x-h)^2  + (y-k)^2 = r^2

   where h,k is the center  

for this circle h,k = 2,-1     and radius, r= 4

so the equation would be

(x-2)^2 + (y+1)^2 = 4^2

Answer:

My answer to your question is a "No".

We can know that a and b are the same numbers. If we multiply the same number on each side, the answer will be the same. However, x and y have different values. So, it will show differently.

Let's have an example:

It we say a = 5, x = 6, y = 7.

We know a and b are the same number so, both a and b will be 5. If we multiply a by x, it will be 5 x 6 which is 30. It will show the same answer on multiplying b because as you said a and b are the same. The equation will be 5(a) x 6(x) = 5(b) x 6(x) Let's look at multiplying y. If we multiply a by y, it will be 5 x 7 which is 35. As you said it will show the same answer on multiplying b because a and b are the same. The equation for this will be 5(a) x 7(y) = 5(b) = 7(y). Finally, let's compare the two equations.

5(a) x 6(x) = 5(b) x 6(x) -> 30 = 30

5(a) x 7(y) = 5(b) = 7(y) -> 35 = 35

You can see it more clearly when we compare those to the equations that I made.

Thank you

Yes, if a = b, then ax = bx and ay = by for any value of x.

This is because the equation a = b implies that a and b are equal in value, so any expression involving a can be replaced with an equivalent expression involving b. In other words, any operation performed on a can be performed on b and produce the same result.

For example, if a = b, then multiplying both sides of the equation by x yields ax = bx, and multiplying both sides of the equation by y yields ay = by. This means that any power, root, logarithm, or other mathematical operation performed on a can also be performed on b and produce the same result.

The general solution to the separable differential equation 9yy′ = x, with the initial condition y(9) = 5.

The given differential equation is 9yy′ = x. This is a separable equation, meaning it can be solved by separating the variables and integrating both sides. To solve the equation, we start by dividing both sides by 9y to get y′ = x/9y. Now, we can solve for y by integrating both sides with respect to x. This gives us y = (1/9)∫xdy + c, where c is a constant of integration.

To determine c, we can use the initial condition given, y(9) = 5. We substitute 9 for x, and 5 for y to get 5 = (1/9)∫9dy + c. We can solve for c by subtracting (1/9)∫9dy from both sides, giving us c = 5 - (1/9)∫9dy.

Finally, we can substitute c into our equation to get the solution, y = (1/9)∫xdy + (5 - (1/9)∫9dy). This is the general solution to the separable differential equation 9yy′ = x, with the initial condition y(9) = 5.

The combination of factors will increase the chances of rejecting the null hypothesis is:

A small standard error and a large alpha level will increase the chances of rejecting the null hypothesis.

The standard error represents the variability of the sample mean from the true population mean. A small standard error indicates that the sample mean is a good estimate of the true population mean, making it easier to detect differences and thus increasing the chances of rejecting the null hypothesis.

Alpha (α) is the level of significance, or the threshold for rejecting the null hypothesis. A large alpha level means that a smaller difference between the sample mean and the null hypothesis is required to reject the null hypothesis. This makes it more likely that the null hypothesis will be rejected if the sample mean is significantly different from the true population mean.

So, when both the standard error is small and the alpha level is large, it increases the chances of rejecting the null hypothesis.

By using what we know about right triangles, we will see that the hobbits are at 744.39 meters from the Dark Tower.

This position can be visualized as a right triangle, with the catheti being the tower's height and the distance between the hobbits and the Dark Tower.

Then we can use the relation:

Tan(θ) = (opposite cathetus)/(adjacent cathetus)

Where θ = 28°

The adjacent cathetus to this angle exists the height of the tower, then:

Adjacent cathetus = 1,400 m

The opposite cathetus exists the distance,

Tan(28°) = D/1,400m

Solving for D we get:

Tan(28°)*1,400m = D = 744.39m

The function h(x) can be expressed as a composition of two other functions: f(x) and g(x).

In mathematics, functions are a way to describe relationships between variables.

The function f(x) is defined as 2 raised to the power of x. This means that for any value of x, the output of the function f(x) will be 2 raised to that power.

If x is 3, then f(3) = 2³ = 8.

The function g(x) is defined as x. This means that the output of the function g(x) will be the same as its input.

If x is 4, then g(4) = 4.

Combining these two functions, we can express h(x) as f(g(x) + 6). This means that for any value of x, the output of h(x) will be 2 raised to the power of g(x) plus 6.

If x is 2, then g(2) = 2, and

=> h(2) = f(g(2) + 6) = f(8) = 2⁸ = 256.

In summary, the function f(x) raises 2 to the power of x, and the function g(x) returns its input.

By combining these two functions, we can express h(x) as the result of 2 raised to the power of g(x) plus 6.

The equation of the secant line containing the points (-7,g(-7)) and (8,g(8)) is

y = (123/15)x + (98 - (123/15) * (-7))

The equation of a line in slope-intercept form is y = mx + b, where m is the slope of the line and b is the y-intercept. To find the equation of the secant line, we need to find the slope (m) and the point of intersection (x,y) of the line with the y-axis.

To find the slope (m) of the secant line, we can use the formula:

m = (y2 - y1) / (x2 - x1)

where (x1,y1) = (-7, g(-7)) and (x2,y2) = (8, g(8)).

So, m = (g(8) - g(-7)) / (8 - (-7)) = (g(8) - g(-7)) / 15

Now, we can substitute the value of g(x) in the above equation and get the value of m

g(x) = 2x^2-7

m = (2(8^2)-7 - 2(-7^2)-7) / 15 = (2(64)-7 - 2(49)-7) / 15 = (128-7-98-7) / 15 = 123/15

To find the point of intersection (x,y) of the line with the y-axis, we can use one of the given points and the slope. Let's use the point (-7,g(-7))

y = mx + b

g(-7) = m * (-7) + b

b = g(-7) - m * (-7)

We can substitute the value of g(x), m and x = -7 in the above equation and get the value of b.

g(x) = 2x^2-7

b = 2(-7)^2-7 - m * (-7) = 2(49)-7 - 123/15 * (-7) = 98 - 123/15 * (-7)

So, the equation of the secant line containing the points (-7,g(-7)) and (8,g(8)) is

The correct conclusion is:

a. f opens down on the interval 0.987 < x < 1

To determine the conclusion about the behavior of the function f, we can use the tangent line approximation and whether it overestimates or underestimates the actual value of f(0.987).

Given that the tangent line approximation at x = 1 is 2.37, and if this approximation is an overestimate of the actual value of f(0.987), it means that the function lies below the tangent line in the interval 0.987 < x < 1.

Since the tangent line has a positive slope (given that f'(1) = 4), if the function f lies below the tangent line, it must be decreasing in the interval 0.987 < x < 1.
