or [tex]c/t=12[/tex]

or [tex]c=12t[/tex]

Hence final answer is [tex]c=12t[/tex].

Answer:

Radius = 2.

Step-by-step explanation:

We have been given equation of the circle which is [tex]x^2 + y^2 = 4[/tex].

Now we need to find the radius of the given circle [tex]x^2 + y^2 = 4[/tex].

To find that let's compare with the formula of the circle with standard equation of the circle  [tex]x^2 + y^2 = r^2[/tex], where r is the radius.

We get [tex]r^2 = 4[/tex]

take square root of both sides.

[tex]r=2[/tex]

Hence radius of the given circle is r = 2.

Area is calculated by multiplication of dimensions:

length×width= Area

both are lesser than 1, let's say 0.5 and 0.9 as examples.

0.5×0.5=0.25

0.9×0.9=0.81

you see the area is less than one and area can never be negative so first answer is the right answer.

The correct statement is option a. The area is between 0 square units and 1 square units

Any 2-diamensional figure bounded by 4 sides in which opposite sides are equal and parallel and all the 4 angles are right angled.

Now,   0 unit<length<1 unit

           0 unit<width<1 unit

∴ Area of the rectangle = (length x width)

⇒ 0 square units <Area of the rectangle <1 square units

∴ The area  of the rectangle is between 0 square units and 1 square units

The first option matches with the answer.

The answer is (-3,2) because when it’s present in the graph the graph would not pass the vertical line test.

Another way to think about it is that -3 (input) has more than one output.

Answer:

The answer is (-3, 2)

Step-by-step explanation:

Let's define the two sets

A = {4, -3, 3, 1} and B = {-2, 2, 4, 1 -3}, so that the set of ordered pairs is a function , we should have that to every element from the first set (in this case A) corresponds (or is associate to) an element (and only one element) from the second set (in this case B). But we have that the element -3 in the set A (the domain) is related to the elements 2 and -3 which belong to the set B (the codomain), this in not allowed by the definition of function. So in order to the set of ordered pairs is a function we should remove the pair (-3, 2).

Answer: D or 36 just answered on apex

Step-by-step explanation:

To find the constant in an equation with a graph, examine the graph's features such as slope, intercept, or specific data points and compare them with theoretical constants provided, like k1, k2, k3, k4, and K3.

The value of the constant in the equation being discussed is related to graphing functions and the characteristics of lines and curves on a graph. In general, when determining a constant from a graph in mathematics, it is essential to look at certain features such as the slope, the intercept, or specific data points depending on the context of the problem. For instance, if we are trying to find a constant of proportionality (k), we might use a linear fit of data points to determine the slope, which then gives us the value of k. Similarly, other constants may be deduced by comparing the theoretical values with the actual data points on the graph.

To determine the value of a constant such as k in a force (F) versus displacement (x) graph, one would label the transition region of the graph and use the given constants (e.g., k1, k2, k3, k4, K3) to measure the force. The slope (m) of the line on the graph is representative of how the value changes along the graph and is calculated using the change in y over the change in x. In situations where the graph does not display a constant force, the value may be represented by the area under the force versus distance graph.

Answer:

Option A

Step-by-step explanation:

The parent function [tex]y=x^2[/tex] has a minimum [tex](0,0)[/tex].

If we map [tex]x\mapsto x-1[/tex] we get [tex]y=(x-1)^2[/tex]. This is a horizontally translated copy of the parent function, so the minimum is still 0.

Then if we map [tex]f(x)\mapsto f(x)-4[/tex] we have [tex]y=(x-1)^2-4[/tex]

This is a vertical translation 4 units down, so now the minimum is -4, which appears in the equation.

The required equation which includes the minimum or maximum of f is given as f(x) = (x - 1)² - 4. Option A is correct.

Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.

here,

First of all, all the function mentioned does not have a maximum,  but have the same minimum, at (1, -4).
But, as of the appearance equation f(x) = (x - 1)² - 4 includes the minimum. because when terminating x it gives minimum y and when terminating it gives x minimum.

Thus, The required equation which includes the minimum or maximum of f is given as f(x) = (x - 1)² - 4. Option A is correct.

Part B) The radius of the rug is [tex]r=5\ ft[/tex]

Part C) The area of the rug is [tex]78.5\ ft^{2}[/tex]

Step-by-step explanation:

Part A) Find the diameter of the rug

we know that

The circumference of a circle (circular rug) is equal to

[tex]C=\pi D[/tex]

where

D is the diameter

we have

[tex]C=31.4\ ft[/tex]

[tex]\pi=3.14[/tex]

substitute the values and solve for D

[tex]31.4=(3.14)D[/tex]

[tex]D=31.4/(3.14)=10\ ft[/tex]

Part B) Find the radius of the rug

we know that

The radius of a circle (circular rug) is half the diameter

we have

[tex]D=10\ ft[/tex]

[tex]r=D/2[/tex]

substitute

[tex]r=10/2=5\ ft[/tex]

part C) What is the area the rug is covering?

The area of the circle (circular rug) is equal to

[tex]A=\pi r^{2}[/tex]

we have

[tex]r=5\ ft[/tex]

Answer:

y = -1/2 x + 1

Step-by-step explanation:

Lines that are perpendicular to each other have slopes that are negative reciprocals. You get the negative reciprocal of a number by flipping the fraction for the slope, then changing the positive/negative.

The lines are written in slope-intercept form, y = mx + b.

"x" and "y" are points on the line.

"m" is the slope.

"b" is the y-intercept.

In y = 2x + 8, the slope is 2. Find its negative reciprocal.

Write the slope as a fraction.

[tex]m=2=\frac{2}{1}[/tex]

Flip the fraction.

[tex]m=\frac{1}{2}[/tex]

Change the negative/positive.

[tex]m=-\frac{1}{2}[/tex]    This is the slope of the perpendicular line.

Now we need to find the y-intercept, "b", for our line. We know m = -1/2, and we know a random point (6, -2). Points are written (x, y), which mean x = 6 and y = -2. Substitute the values of the point and the slope into y = mx + b.

[tex]y = mx + b[/tex]

[tex]-2 = -\frac{1}{2}*6 + b[/tex]      Multiply (-1/2)(6) by combining into the numerator

[tex]-2 = -\frac{6*1}{2} + b[/tex]      Simplify numerator

[tex]-2 = -\frac{6}{2} + b[/tex]       Reduce fraction

[tex]-2 = -3 + b[/tex]         Isolate "b" now

[tex]-2 + 3 = -3 + b + 3[/tex]      Add 3 to both sides

[tex]1 = b[/tex]        Solved for "b"

[tex]b=1[/tex]         Write the variable on the left side for standard formatting

b = 1 and m = -1/2

Substitute them into slope-intercept form for the final answer.

y = -1/2 x + 1

To find the equation of a line perpendicular to a given line and passing through a specific point, use the negative reciprocal of the original line's slope. Applying this to the point-slope form of the line equation gives y = -(1/2)x + 1, which is the correct answer as per the given options.

The subject of the question is about writing the equation of a line that is perpendicular to another line, specifically y = 2x + 8, and passes through a specific point (6, -2). The concept involved here is the slope of the lines. The slope of a line perpendicular to another is the negative reciprocal of the original line's slope. Since the slope of our given line is 2, the slope of the line that is perpendicular to this would be -1/2.

Using the point-slope form of a linear equation, y - y1 = m(x - x1), where m is the slope, and (x1, y1) is the point through which the line passes, we can substitute m = -1/2 and (x1, y1) = (6, -2). Therefore, the equation of the line is y = -(1/2)x + 1.

The correct answer from the given options is (D) y = -(1/2)x + 1.

ANSWER IS 656

To solve for the vertical angles, we set up the equation 2y = y + 130. Solving for y gives us 130, and substituting back, we get each angle measures 260 degrees, which is reasonable since vertical angles are equal.

Two angles are vertical angles, which means they are opposite each other when two lines intersect and they are equal in measure. The problem states that one angle is 2y and the other is y + 130. Since vertical angles are equal, we can set up the equation 2y = y + 130.

Now, we solve for y:

To check if the answer is reasonable, we can note that vertical angles must be equal, and both our calculated angles are 260 degrees, confirming they are equal and thus reasonable.

Final answer:

The equation y = -x² - 2x + 3 can be expressed in vertex form as y = -(x + 1)² + 4.

Explanation:

The equation y = -x² - 2x + 3 can be expressed in vertex form as:

y = -(x + 1)² + 4

To convert the equation to vertex form, we need to complete the square. Here are the steps:

Factor out a common negative from the first two terms: y = -1(x² + 2x) + 3

Take half the coefficient of x (-2/2 = -1) and square it: (-1)² = 1

Add the squared value inside the parentheses and subtract it outside: y = -(x² + 2x + 1) + 3 - 1

Simplify: y = -(x + 1)² + 2

The vertex form of the equation is y = -(x + 1)² + 4.

⇒ 4y = x

Put x = 4y in 2nd Equation ,

⇒ 5*4y - 8y = 33

⇒ 20y - 8y = 33

⇒ 12y = 33

⇒ y = 33/12

Put this in 1st ,

⇒ 33/12 = 1/4 x

⇒ x = 33/12 × 4

⇒ x = 33/3
