Use the figure to decide the type of angle pair that describes angle 3 and angle 2​

The value of y from the given equation with x=2+i is y= 7(i+2).

The given equation is y= x²+3x+5.

We need to evaluate y from the given equation for x= 2+i.

A complex number is the sum of a real number and an imaginary number. A complex number is of the form a + ib and is usually represented by z. Here both a and b are real numbers. The value 'a' is called the real part which is denoted by Re(z), and 'b' is called the imaginary part Im(z).  Also, ib is called an imaginary number.

The alphabet i is referred to as the iota and is helpful to represent the imaginary part of the complex number. Further the iota(i) is very helpful to find the square root of negative numbers.

Now, put x= 2+i in y= x²+3x+5 and simplify.

That is, (2+i)²+3(2+i)+5

=4+i²+4i+6+3i+5

=15-1+7i

=7i+14

=7(i+2)

Therefore, the value of y from the given equation with x=2+i is y= 7(i+2).

Point if discontinuity:  

{x}=  \pm3

Zero of the function is  

x = 0

EXPLANATION

The given rational function is:

f(x) =  \frac{3x}{ {x}^{2}  - 9}  

This function is not continous when  

{x}^{2}  - 9 = 0

{x}=  \pm \sqrt{9}  

{x}=  \pm3

The function is zero when,

3x = 0

x = 0

Answer:

x = 0 is the zero of this function and at x = ±4 function is discontinuous.

Step-by-step explanation:

The given function is [tex]f(x) = \frac{4x}{x^{2}-16}[/tex]

For this function we have to find the discontinuity and zeros of this function.

For zeros of the function [tex]0 = \frac{4x}{x^{2}-16}[/tex]

so zero of the function is x = 0

For x² - 16 = 0 this function not defined therefore, x = ± 4 function will be discontinuous.

Finally, x = 0 is the zero of this function and at x = ±4 function is discontinuous.

Answer:

10.2 inches

Step-by-step explanation:

Ok let's assume we don't know the larger (the c value).

So this means using [tex]a^2+b^2=c^2[/tex] we have:

[tex]12^2+15^2=c^2[/tex]

[tex]144+225=c^2[/tex]

[tex]369=c^2[/tex]

Square both sides:

[tex]c=\sqrt{369} \aprox 19.2[/tex

Now assume we know the larger is 15 (this means c=15 now), then we have

[tex]a^2+12^2=15^2[/tex]

[tex]a^2+144=225[/tex]

Subtract 144 on both sides:

[tex]a^2=225-144[/tex]

Simplify:

[tex]a^2=81[/tex]

Square root both sides:

[tex]a=9[/tex]

The difference between 19.2 and 9 is 19.2-9=10.2.

Answer:

Option 1 - 10.2 inches.                            

Step-by-step explanation:

Given : The lengths of two sides of a right triangle are 12 inches and 15 inches.

To find : What is the difference between the two possible  lengths of the third side of the triangle?

Solution :

Since, It is a right angle triangle so we apply Pythagoras theorem,

[tex]C^2=A^2+B^2[/tex]

Where, C is the hypotenuse the longer side of the triangle

A is the perpendicular

B is the base

There will be two cases,

1) Assume that C=15 inches and B = 12 inches

Substitute the value in the formula,

[tex]15^2=A^2+12^2[/tex]

[tex]225=A^2+144[/tex]

[tex]A^2=225-144[/tex]

[tex]A^2=81[/tex]

[tex]A=\sqrt{81}[/tex]

[tex]A=9[/tex]

Assume that A=15 inches and B = 12 inches

Substitute the value in the formula,

[tex]C^2=15^2+12^2[/tex]

[tex]C^2=225+144[/tex]

[tex]C^2=369[/tex]

[tex]C=\sqrt{369}[/tex]

[tex]C=19.2[/tex]

Therefore, The possible length of the third side of the triangle is

[tex]L=C-A[/tex]

[tex]L=19.2-9[/tex]

[tex]L=10.2[/tex]

Therefore, The difference between the two possible  lengths of the third side of the triangle is 10.2 inches.

So, Option 1 is correct.

The line of reflection which maps the point K to K' and L to L' is Y axis.

Reflection is the transformation where the image is flipped.

Line of reflection is the line for which a figure has a mirror image over that line.

Given a triangle JKL.

Let the coordinate of the triangle be J(4, 5), K(5, 2) and L(2, 3).

When a coordinate (x, y) is reflected over the X axis, then the coordinates changes to (x, -y).

When a coordinate (x, y) is reflected over the Y axis, then the coordinates changes to (-x, y).

Here,

K(5, 2) changes to K'(-5, 2).

Here x coordinate changes sign.

So the line of reflection is Y axis.

Similarly, the line of reflection for the other transformation is also Y axis.

Hence the line of reflection is Y axis.

if 60min = 360°

32min = ?

32×360

60

=192°

Answer:

B. 192 degrees

Step-by-step explanation:

First, calculate how many degrees a minute equals.

The minute hand rotates 360 degrees every 60 minutes.

Thus, one minute is equivalent to dividing 360 degrees by 60 minutes, that is 360/60 = 6 degrees per minute.

Now, we subtract the minutes from the two hours given,

12:49 PM - 12.17 PM = 32 minutes

Finally, we calculate the angle traveled by the minute hand by multiplying 6 degrees by 32 minutes, that is

Angle = 6 * 32 = 192 degrees.

Answer:

The domain is all real numbers and the range is non-negative real numbers

(y ≥ 0) ⇒ answer B

Step-by-step explanation:

* Lets revise the parent function of the absolute value

- The absolute value or modulus |x| of a real number x is the

  non-negative value of x

- The absolute value of a number means the magnitude of the number

  without regard to its sign

- The parent function of the absolute value is f(x) = IxI

∵ The domain of the function is all the values of x which make the

  function defined

∵ In the function f(x) = IxI, x can be any number

∴ The domain of the f(x) is any real number

∴ The domain is (-∞ , ∞) or {x : x ∈ R}

∵ The range is the set of values of y that corresponding with the

   domain

∵ f(x) = IxI is non-negative value

∴ f(x) ≥ 0

∵ f(x) = y

∴ y ≥ 0

∴ The range is the set of real numbers greater than or equal zero

∴ The range is [0 , ∞) or {y : y ≥ 0}

* The true statement is: The domain is all real numbers and the range is

  non-negative real numbers (y ≥ 0)

Answer:

[tex]x = 1[/tex].

Step-by-step explanation:

Apply the associative property of addition to rewrite the left-hand side of the equation.

The two addition operators on the left-hand side are typically evaluated from left to right.

[tex](2x + 8) - 6 = 4[/tex].

However, by the associative property of addition, the second addition can be evaluated before the first:

[tex]2x + (8 - 6) = 4[/tex].

[tex]2x + 2 = 4[/tex].

Move all terms with the unknown ([tex]x[/tex] in this case) to one side of the equation and move all numbers to the other side. For example, add [tex]-2[/tex] to both side of this equation will move the number [tex]2[/tex] to the right-hand side.

[tex]2x +2 -2 = 4 - 2[/tex].

[tex]2x = 2[/tex].

Multiply both sides of the equation by [tex]1/2[/tex] to find the value of [tex]x[/tex].

[tex]x = 1[/tex].

Answer:

A:A(6t)=πp^2

B: about 7234.56

Step-by-step explanation:

First find A[p(t)], Since this is a composite function so whenever you see p(t), you replace it with 6t, that is the value of p(t).

This is a simplified version of the area of the circle as a function of time A(6t)=πp^2

To find how large the area of paint spilled plug in 8 for t because t represents time.

A(48)≈3.14(48)^2

A(48)≈3.14*2304

A(48)≈7234.56

Final answer:

To find the area of spilled paint over time, we replace the time-dependent spread 'p(t)' in the area function 'A(p) = πp²' with '6t'. This results in the equation 'A[p(t)] = 36πt²'. After 8 minutes, the area is approximately 7233.76 square units when using 3.14 for π.

Explanation:

To solve for the area of the circle of spilled paint as a function of time, we need to use the given functions. We are given p(t) = 6t, which represents how far the paint spreads over time in minutes. The area of the circular pattern is given by A(p) = πp².

Part A

To find A[p(t)], we substitute the expression for p(t) into the equation for A(p):

A[p(t)] = π(6t)²
= π(36t²)
= 36πt²

Part B

After 8 minutes, the area of spilled paint can be calculated by substituting t=8 into the function A[p(t)]:

A[p(8)] = 36π(8)²
= 36π(64)
= 2304π
≈ 2304(3.14)
≈ 7233.76 square units

y < 2 and y >= x

Because the dotted line shows that y < 2 and y >=x is shown is represented by diagonal line.

Option: D is the correct answer.

      D.    y<2   and    y≥x

The graph of the system of linear inequalities are two lines:

1)

The first is a solid line which passes through (0,0) , (1,1)

i.e. the equation of the line is: y=x

and the inequality will be a inequality with a equality sign ( since the line is solid ) and the shaded region is above the line .

Hence, the inequality is: y≥x

2)

The second line is a dotted line.

This means that the inequality is strict.

Also, the line is a horizontal line parallel to the x-axis and the line pass through (0,2) and the shaded region is below the line.

Hence, the inequality is given by:

                    y<2

For this case we have by definition, the GFC of two numbers is given by the largest factor that divides both numbers without leaving residue.

We have the following expression:

[tex]3p ^ 4[/tex] and [tex]4p[/tex]

So, we look for the factors of 3 and 4:

3: 1.3

4: 1, 2, 4

Thus, the GFC of both numbers is "1".

The GFC of both expressions is: [tex]1p = p[/tex]

Answer:

Step-by-step explanation:

i got it right on the quiz

Points with opposite x-coordinates and the same y-coordinate are symmetrically placed with respect to the y-axis. Their distance from the y-axis is the absolute value of their x-coordinate.

If points A and B have opposite x-coordinates but the same y-coordinates, we can deduce that they are positioned symmetrically with respect to the y-axis. The distance of each point from the y-axis is equal to the absolute value of their x-coordinate. This is because the y-axis serves as a reference line where the x-coordinate is zero.

For example, if point A has coordinates (-5, 3) and point B has coordinates (5, 3), then both points are 5 units away from the y-axis. The only difference between their positions is the direction relative to the y-axis; point A is on the left side and B is on the right side.

So, the general rule is that no matter the y-coordinate, the distance of a point from the y-axis is simply the absolute value of its x-coordinate.

As per the contract "Notification of the Buyer’s intent to do so must be made by written letter or phone call to the phone number and address listed below within one business week of delinquency.”

So,buyer needs to only notify the bank about the monthly payments in case of delinquency and not about if payment is going to be late or not.

Option B is correct

Notify the bank if a payment is going to be late !

The buyer is not responsible for paying an additional $75.00 for payments made after the 15th of the month it was due; this is not specified in the contract's provided clauses.

According to the contract, the responsibility that is not a part of the buyer's obligations is option (c): Pay an additional $75.00 with a payment made after the 15th day of the month it was due. The contract stipulates that the buyer should pay the monthly payment on time (a), notify the bank if a payment is going to be late (b), and notify the bank of his or her intent to split a late payment into three partial payments (d) in the event of delinquency. However, there is no mention within the provided excerpt of the contract that indicates an additional fee of $75.00 is imposed for late payments. It is important for individuals facing financial difficulties, such as inability to make timely payments, to communicate effectively with their lenders to find potential solutions and avoid the repercussions of default.

Answer:

A) 760 ft³

Step-by-step explanation:

The surface area of the figure has to be calculated.

Step 1: Divide the figure

The figure is divided into the following parts to calculate the volume.

Part 1: Box without ledge

Formula for volume of rectangle = length x width x height

Volume = 14.3 x 7.8 x 6.6

Volume = 736.164 ft³

Part 2: Box with ledge-we will only calculate height and width since the length has already been included in part 1 therefore including it again would result in double counting and give the wrong answer.

Volume = height x width

Volume = 2.7 x 7.8

Volume = 21.06 ft³

Step 2: Add both volumes to find the total volume

Volume part 1 + Volume part 2 = 736.164 ft³ + 21.06 ft³

= 757.224 ft³ rounded off to nearest tenth = 760 ft³

Therefore, answer A is correct.
