What is the equation of a circle whose center is at the origin and whose radius is 16?x 2 + y 2 = 256x 2 + y 2 = 4x 2 + y 2 = 16

The given function f(x) = 2x - 4 undergoes four transformations: vertical stretch, vertical translation, horizontal reflection, and horizontal translation. The expressions representing each transformation are as follows:

The given function f(x) = 2x - 4 can be transformed in various ways. Let's analyze each transformation individually.

1. Vertical Stretch:

A vertical stretch multiplies the function's output (y-value) by a constant. In this case, the expression for the vertical stretch is:

f₁(x) = a * f(x)

where 'a' is the scaling factor. This transformation affects the function's steepness. If 'a' is greater than 1, the graph becomes steeper; if 'a' is between 0 and 1, the graph becomes flatter.

2. Vertical Translation:

A vertical translation shifts the function up or down by adding or subtracting a constant to the function's output (y-value). The expression for the vertical translation is:

f₂(x) = f(x) + b

where 'b' represents the amount of vertical shift. If 'b' is positive, the graph shifts upward; if 'b' is negative, the graph shifts downward.

3. Horizontal Reflection:

A horizontal reflection flips the function across the y-axis. The expression for the horizontal reflection is:

f₃(x) = -f(x)

This transformation changes the sign of the function's output for every input value, resulting in a mirror image of the original graph.

4. Horizontal Translation:

A horizontal translation shifts the function left or right by adding or subtracting a constant to the function's input (x-value). The expression for the horizontal translation is:

f₄(x) = f(x - c)

where 'c' represents the amount of horizontal shift. If 'c' is positive, the graph shifts to the right; if 'c' is negative, the graph shifts to the left.

The number real solutions the equation have u² = -34 is no real solution, the correct option is A.

We are given that;

Function u² = -34

Now,

A linear equation is an equation that has the variable of the highest power of 1. The standard form of a linear equation is of the form Ax + B = 0.

The equation u^2 = -34 has no real solutions. This is because there is no real number u that satisfies u^2 = -34. To see this, we can try to solve for u by taking the square root of both sides:

u = ±sqrt(-34)

However, the square root of a negative number is not a real number. It is an imaginary number that involves the imaginary unit i, defined by i^2 = -1. Therefore, u = ±sqrt(-34) is not a real solution. The equation u^2 = -34 has only imaginary solutions.

Therefore, by equations the answer will be no real solution.

The center of circle is: (-7,4) and Radius is 7 units

Keywords: Circle, radius

Answer:

Step-by-step explanation:

First expand the equation

That's

( x - 4)² + ( y - 7)² = 49

x² - 8x + 16 + y² - 14y + 49 - 49 = 0

x² + y² - 8x - 14y + 16 = 0

Comparing with the general equation of a circle

x² + y² + 2gx + 2fy + c = 0

2g = - 8 2f = - 14

g = - 4 f = - 7 c = 16

Center of a circle is ( - g , - f)

( --4 , --7)

Which is ( 4 , 7)

The radius of the circle is given by

r = √g² + f² - c

Where r is the radius

r = √ (-4)² + (-7)² - 16

= √16 + 49 - 16

= √49

The value of cv1, the lower critical value, is approximately 54.19.

To find the critical value (cv1) for a two-tailed hypothesis test at a 10% significance level, we need to divide the significance level (α) by 2.

Since α = 0.10, we divide it by 2 to get 0.10/2 = 0.05.

Next, we need to find the z-score associated with the cumulative probability of 0.05.

Using a standard normal distribution table or a calculator, we can find that the z-score for a cumulative probability of 0.05 is approximately -1.645.

Now, we can calculate the critical value by multiplying the z-score by the standard deviation (27) and adding it to the population mean (100).

cv1 = 100 + (-1.645 * 27)
cv1 ≈ 54.19 (rounded to two decimal places)

Therefore, the value of cv1, the lower critical value, is approximately 54.19.

Note that the angles of the triangle whose vertexes are the centers of the circles are  50.48°, 58.99°, 70.53°.

Three circles with radii 4, 5, and 6 from a triangle whose sides are the sum of their radii in pairs.

Thus, the sides of the triangle are

4 + 5, 4 + 6, and 5+6.

⇒ 9,, 10, 11.

To find the interior angles

CosC = a² + b² + c²/ 2ab

With a credit card balance of $17,426, a minimum monthly payment of $461, and an interest rate of 15.5%, we need to calculate the number of years it will take to pay off the card without adding any additional debt.

To determine the time required to pay off the credit card, we consider the monthly payment and the interest rate. Each month, a portion of the payment goes towards reducing the balance, while the remaining balance accrues interest.

To calculate the time needed for repayment, we track the decreasing balance each month. First, we determine the interest accrued on the remaining balance by multiplying it by the monthly interest rate (15.5% divided by 12).

We continue making monthly payments until the remaining balance reaches zero. By dividing the initial balance by the monthly payment minus the portion allocated to interest, we obtain the number of months needed for repayment. Finally, we divide the result by 12 to convert it into years.

In this scenario, it will take approximately 3.81 years to pay off the credit card (17,426 / (461 - (17,426 * (15.5% / 12))) / 12).

To find the absolute maximum value of the function g(x)=−2x^2/x−1 over the closed interval [−3,5], we will use the Extreme Value Theorem (EVT).EVT states that if a function is continuous over a closed interval, then the function will have an absolute maximum and minimum over that interval.

So, for finding the absolute maximum value of the given function, we will follow these steps:Step 1: Check the function's domain.We know that the denominator of the function g(x) is x - 1, so the function is not defined at x = 1. However, the closed interval we are working with is [-3, 5], which does not include x = 1. Hence, the function is defined over this interval.Step 2: Find the critical points of the functionTo find the critical points, we need to differentiate the function g(x) and equate it to zero:g'(x) = (-4x(x-1) + 2x^2)/(x-1)^2= 2x(3-x)/(x-1)^2=0So, the critical points of g(x) are x = 0 and x = 3.Step 3: Find the end-point values of the functiong(-3) = -2/5, g(5) = -50/9.

Therefore, the total distance Gabe will paddle is 2x + 400 meters. The exact value of x depends on the width of the river, which is not provided in the given information.

To find the total distance Gabe will paddle, we need to consider the distance he will travel from Q to P, then from P to R, and finally from R back to Q.

First, let's consider the distance from Q to P. Since Gabe will paddle in a diagonal line across the river, this distance can be calculated using the Pythagorean theorem.

The length of the bridge (PR) is given as 400 meters, which is the hypotenuse of a right triangle. The width of the river can be considered as the perpendicular side, and the distance Gabe will paddle from Q to P is the other side. Let's call this distance x.

Using the Pythagorean theorem, we have:

x^2 + (width of the river)^2 = PR^2

Since the width of the river is not given, we'll represent it as w. Therefore:

x^2 + w^2 = 400^2

Next, let's consider the distance from P to R. Gabe will paddle along a route beside the bridge, which means he will travel the length of the bridge (PR) again. So, the distance from P to R is also 400 meters.

Finally, Gabe will paddle back from R to Q along the shore. Since he will follow the shoreline, the distance he will paddle is equal to the distance from Q to P, which is x.

To find the total distance, we add up the distances:

Total distance = QP + PR + RQ

= x + 400 + x

= 2x + 400

There are 2 solutions to square root x = 9

They are 3, and -3

Step-by-step explanation:

The square root of x=9 has 2 solutions,

The square root means, for a given number, (in our case 9) what number times itself equals the given number,

Or, squaring (i.e multiplying with itself) what number would give the given number,

so, we have to find the solutions to \(\sqrt{9}\)

since we know that,

\((3)(3) = 9\\and,\\(-3)(-3) = 9\)

hence if we square either 3 or -3, we get 9

Hence the solutions are 3, and -3
