The graphs of f(x) =2/3x and g(x) =2/3x-2 are shown below.

Angles whose terminal sides lie on the x and y axis are Quadrantal angels.

Hope it helps.

Answer:

The correct answer option is c) quadrantal angles.

Step-by-step explanation:

When the terminal sides lie on the x axis or the y axis in the standard position, the angles are called as quadrantal angles.

For example when one of the sides lie on the x axis and one lies on the y axis, it makes an angle of 90 degrees which is a quadrantal angle (as shown in the picture attached).

Undefined terms such as points and lines are central to defining geometric concepts such as line segments and angles. They also play a crucial role in the Cartesian coordinate system, where points are defined in relation to lines (axes).

In Mathematics, particularly in Geometry, the undefined terms points and lines are used to define several other concepts. One such concept defined by these undefined terms is the 'Line Segment'. A Line Segment is simply part of a line that is bounded by two distinct endpoints, and contains every point on the line between its endpoints. Both points and lines have a defining role in constructing this definition. A line segment is an example of 'one-dimensional' structure, as it only extends in one direction, unlike a plane or volume that extend in two or three dimensions, respectively.

Another major concept that is defined using points and lines is the 'Angle'. An angle is formed when two lines meet at a point. The point is called the vertex of the angle, and the lines are the sides of the angle.

In the Cartesian coordinate system, the interaction of points and lines is at the core of defining and plotting positions. For example, a point in this system is represented by two coordinates (x, y) - where x represents its position along the x-axis (a horizontal line) and y represents its position along the y-axis (a vertical line).

Answer:

The diameter of circle d is 9.03

Step-by-step explanation:

Circumference of Circle = 28.36

We need to find the diameter of circle.

The formula used to find the circumference of circle is:

C = 2πr

we know that radius is half of diameter

so r = d/2

Putting value of r in above equation

C = 2π(d/2)

C = πd

The value of π is 3.14. finding value of d

28.36 = 3.14 * d

=> d = 28.36 / 3.14

d = 9.03

So, the diameter of circle d is 9.03

Answer:

The diameter is approximately 9 units

Step-by-step explanation:

Circumference is given by

C = pi *d

28.36 = pi *d

Let use 3.14 for pi

28.36 = 3.14 *d

Divide each side by 3.14

28.36 /3.14 = 3.14 d/3.14

9.031847134 = d

The diameter is approximately 9 units

Answer:

T'={1}

Step-by-step explanation:

Definition:

Given a set T, the complement of T is the set of all elements in the universal set U, but not in T.

We can write T^c  

You can also say complement of T in U

Complement of T( T')= U-T

where U={1,2} and T={2}

Now put the sets of U and T in the formula:

T'=U-T

T'={1,2}-{2}

T'{1}

Thus the Complement of T(T')={1}....

The complement of a set T in a universal set U is all the elements in U that are not in T. If U={1,2} and T={2}, the all the elements in U that are not in T corresponds to {1}. So, the complement of T is {1}.

In the field of Mathematics, specifically in set theory, the complement of a set T in a universal set U is the set of all elements in U that are not in T. When we say complement of T, we are referring to the set of all outcomes in the universal set U that are NOT in T.

In this case, the universal set U={1,2}, and the event T={2}. Therefore, the complement of the set T in relation to U would be the set of all elements in U that are not in T. Hence, since 2 is in T, the only number left in U that is not in T is 1. So, the complement of T is {1}.

Option A.

it has only one x value that is x = 2

Not correct.

Option B.

In this graph straight line doesn't intersect x - axis at x = -2 and -4.

So Not correct.

Option C.

If we see the x- values of the given set of coordinates, we find domain of the given function is { -4, -2, 2, 4}

Therefore, it's correct option.

Option D.

Given set with the coordinates shows domain set as {1, 0, 2, 6}

Your question asks to make an equation with the information that was given.

In order to make an equation for your question. We would be making an equation with the formula: y = mx + b.

Formula: y = mx + b

m = change

x = amount of ice cream

b = starting value

We would need to gather the key information from the question.

Key information:

You have $30

Each ice cream cost $5

With the information above, we can make an equation for the question.

What we know is that you started with $30, so that means that 30 would be your b value (starting value).

Your equation should look like this:

y = mx + 30

Now, we know that each ice cream cost $5, but since we're paying for the ice cream, we would subtract that from our starting value. This means that our change would be -5, since we are taking away $5 each time we buy ice cream.

Your equation should look like this:

y = -5x + 30

The equation above would be the equation for your question.

We would do nothing to x but just leave it as is, since we don't know how many ice creams you're going to buy.

y = -5x + 30 should be your FINAL answer.

Step-by-step explanation:

Recall the formula for the surface area of a sphere and a radius of r

A = 4πr²

In our case, we are given that A = 2826 ft² = 406944 in²

so,

406944 = 4πr²

r² = 406944 / (4π)      (use π=3.142)

r² = 406944 / (4π)  = 32383.57

Answer: [tex]y=-3(x+1)^2+4[/tex]

Step-by-step explanation:

The vertex form of the equation of  a parabola is:

 [tex]f(x) = a(x - h)^2 + k[/tex]

Where (h, k) is the vertex of the parabola.

To write [tex]y=-3x^2 - 6x +1[/tex] in vertex form, you need to complete the square:

1. Move the 1 to the other side of the equation:

[tex]y-1=-3x^2 - 6x[/tex]

2. Since the leading coefficient must be 1, you need to factor out -3:

[tex]y-1=-3(x^2 + 2x)[/tex]

3. Divide the coefficient of the x-term inside the parentheses by 2 and square it:

  [tex](\frac{2}{2})^2=1[/tex]

4. Now add 1 inside the parethenses and -3(1) to the other side of the equation (because you factored out -3):

[tex]y-1-3(1)=-3(x^2 + 2x+1)[/tex]

[tex]y-4=-3(x^2 + 2x+1)[/tex]

5. Convert the right side of the equation to a squared expression:

 [tex]y-4=-3(x+1)^2[/tex]

6. And finally, you must solve for "y":

[tex]y=-3(x+1)^2+4[/tex]

1. Carl's constant rate of speed is the slope of the straight line graph.

This straight line passes through: (0,0), (5,1), (10,2) etc

We can use the slope formula with any two points to find the slope of this line.

The slope formula is [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex].

Let [tex](x_1,y_1)=(0,0)[/tex] and [tex](x_2,y_2)=(5,1)[/tex]

Then [tex]m=\frac{1-0}{5-0}[/tex], [tex]\implies m=\frac{1}{5}[/tex].

Carl's speed is [tex]\frac{1}{5}[/tex] miles per minute.

But we must leave our answer in miles per hour

Hence Carl's speed is [tex]\frac{1}{5}\times 60=12[/tex]  miles per hour

After 2 hours, Carl will travel [tex]12\times 2=24[/tex] miles.

2. The given line has equation [tex]-4x+y=10[/tex]

We write this in slope-intercept form by solving for y.

[tex]\implies y=4x+10[/tex]

This is in the form [tex]y=mx+c[/tex], where [tex]m=4[/tex] is the slope.

When x=3,  [tex]y=4(3)+10[/tex]

[tex]\implies y=12+10=22[/tex]

When x=3, y=22

3. The given straight line graph that models the situation passes through:

Answer:

y = [tex]\frac{3}{2}[/tex] x - 4

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Rearrange 3x - 2y = - 6 into this form

Subtract 3x from both sides

- 2y = - 3x - 6 ( divide all terms by - 2 )

y = [tex]\frac{3}{2}[/tex] x + 3 ← in slope- intercept form

with slope m = [tex]\frac{3}{2}[/tex]

• Parallel lines have equal slopes, hence

y = [tex]\frac{3}{2}[/tex] x + c ← partial equation of parallel line

To find c substitute (4, 2) into the partial equation

2 = 6 + c ⇒ c = 2 - 6 = - 4

y = [tex]\frac{3}{2}[/tex] x - 4 ← equation of parallel line

Area of a rectangle is Length times width.

The Width is given as X and the length is 2x+3

Now you have x * 2x+3 = 230

Multiplying x to 2x+3 = 2x^2 +3x

2x^2 +3x = 230

Subtract 230 from both sides:

2x^2+3x-230 = 0

Factor the polynomial:

(x-10) (2x+23) = 0

Solve for each x:

x = 10 and X = -11.5

Since a side of a rectangle can't be a negative number x = 10.

The width = x = 10 yards.

The length = 2(10) +3 = 23 yards.

It's A-all real numbers less than or equal to 7

Step-by-step explanation:

I just took the unit test and got a 100 on it!

The range of the function f(x) = -(x + 3)² + 7 is {y: y ∈ R, y ≤ 7}. So, option A is correct.

Given that,

f(x) = -(x + 3)² + 7

⇒ y = -(x + 3)² + 7

⇒ (x + 3)² = 7 - y

⇒ (x + 3) = √(7 - y)

⇒ x = (√(7-y)) - 3

Thus, all the real values less than or equal to 7 for y define the function. So, the domain for the obtained function is {y: y ∈ R, y ≤ 7}.

Therefore, the range of the given function is {y: y ∈ R, y ≤ 7}.

Answer:

Step-by-step explanation:

Solve the system:

8x−4y=20

4x−8y=4

Reduce the first equation by dividing every term by -2:

-4x + 2y = -10

and then combine this result with the second equation:

4x−8y=4

-4x + 2y = -10

--------------------

      -6y = -6, and so y = 1.  

According to the first equation, if y = 1, then 4x - 8 = 4, or x = 3.

Then x = 3 and y = 1.

So, finally, x - y = 3 - 1 = 2
