A rigid transformation is a transformation that preserves the shape and size of an object. It includes translations, rotations, and reflections. Without specific information about the coordinates or measurements of the triangles, it is not possible to determine if a rigid transformation exists.

A rigid transformation is a transformation that preserves the shape and size of an object. It includes translations, rotations, and reflections. In order for triangle ΔABC to be mapped to triangle ΔDEC, there must be a combination of translations, rotations, and reflections that can bring the two triangles into congruence.

However, without specific information about the coordinates or measurements of the vertices of the triangles, it is not possible to accurately determine if a rigid transformation exists that can map ΔABC to ΔDEC.

Slope intercept form:

y=mx+b

Right now we have:

-y=4-x

x=1 because it’s not being multiplied by anything

y-intercept = 4 because it’s what you’re adding

Then we just need to move 4 to the other side of “x”

And with that, we conclude with a line in slope intercept form:

-y=x-4

It’s a negative 4 and a positive x, because you’re supposed to do the opposite

If it’s a negative, you add. If it’s a positive, you subtract.

1. 0.5(-12p - 4) =

-6p - 2 is the answer.

Hope this helped!!!!

~Shane

Final answer:

The expression 0.5(-12p - 4) simplifies to -6p - 2 by distributing the 0.5 across each term inside the parentheses, resulting in the multiplication of -12p by 0.5 to get -6p, and -4 by 0.5 to get -2.

Explanation:

The expression 0.5(-12p - 4) can be simplified by distributing the 0.5 across the terms inside the parentheses. This is done by multiplying 0.5 by each term in the parentheses individually. The steps are as follows:

Multiply 0.5 by -12p, which gives us -6p.

Multiply 0.5 by -4, which gives us -2.

Combine these results to get the simplified expression, which is -6p - 2.

Therefore, 0.5(-12p - 4) equals -6p - 2.

AB and DC are parallel to each other and both are perpendicular to AD. So the quadrilateral is a right angled trapezoid. Hope this helps! :)

Final answer:

The given quadrilateral cannot be classified into a specific type.

Explanation:

The given quadrilateral has vertices with coordinates (-3,1), (0,3), (5,2), and (-1,-2). To determine the type of quadrilateral, we can find the slopes of the opposite sides. If the slopes are equal, the quadrilateral is a parallelogram. If the slopes are perpendicular, the quadrilateral is a rectangle. If both conditions are satisfied (equal slopes and perpendicular slopes), then the quadrilateral is a square.

Using the formula for slope between two points, we find:

Slope of the first side: (-3,1) to (0,3) -> m1 = (3 - 1) / (0 - (-3)) = 2/3

Slope of the second side: (-1,-2) to (-3,1) -> m2 = (1 - (-2)) / (-3 - (-1)) = 3/2

Slope of the third side: (-3,1) to (5,2) -> m3 = (2 - 1) / (5 - (-3)) = 1/8

Slope of the fourth side: (0,3) to (5,2) -> m4 = (2 - 3) / (5 - 0) = -1/5

Since the slopes of opposite sides are neither equal nor perpendicular, the given quadrilateral is neither a parallelogram, rectangle, nor a square. Therefore, the type of quadrilateral cannot be determined.

Discriminant = 88

Step-by-step explanation:

The general form of quadratic polynomial is:

P(x) = ax² + bx + c ⇒ a is the coefficient of x² , b is the coefficient

of x and c is the numerical term

∵ The discriminant of P(x) = ax² + bx + c is b² - 4ac

∵ P(x) = 2x² + 4x - 9

∴ a = 2 , b = 4 , c = -9

∴ Discriminant = (4)² - 4(2)(-9) = 16 + 72 = 88

Answer:

The discriminant of given polynomial is 88.

Step-by-step explanation:

We have given a polynomial.

Answer:

The radius is 4.5 ft

Step-by-step explanation:

The volume of a sphere is

V = 4/3 pi r^3

121.5 pi = 4/3 pi r^3

Divide each side by pi

121.5 = 4/3 r^3

Multiply each side by 3/4

121.5 *3/4 = r^3

91.125 = r^3

Take the cube root on each side

(91.125) ^(1/3)= (r^3)^(1/3)

4.5 = r

The radius is 4.5 ft

Answer and Explanation :

To find : What is the phase shift of a periodic function?

Solution :

The Phase shift is defined as a horizontal shift in a function in any direction.

Horizontal stretches will change the period of the function and that horizontal shift is called a phase shift or the amount of shift in a wave horizontally.

The phase shift is measured in degrees.

Refer the attached figure below for the pictorial representation of teh phase shift.

In the figure, [tex]\frac{\pi }{2} \text{ to } \pi[/tex] is showing the phase shift.

Example - Taking a general example of sin function

[tex]y = A \sin(B(x + C)) + D[/tex]

In this the phase shift is at C (positive is to the left).

The measure of angle XYA is 26 degrees if the YX is a tangent to circle O at point X.

It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)

We have:

YX is a tangent to circle O at point X.

Arc XB = 52 dergees

Arc XA = 104 degrees

By the theorem of secant:

m∠XYA  =  1/2(m∠arc XA - m∠arc XB)

= 1/2(104 - 52)

= 26 degrees

Thus, the measure of angle XYA is 26 degrees if the YX is a tangent to circle O at point X.

For 1 year Jeff pays $1200.

For 6 years he pays 7200 / 6 = 1200 per year.

For 9 years he pays 10800 / 9 = 1200 per year.

Jeff's unit rate is $1,200 per year.

Daniel pays $1,150 per year.

150 is less than 1200, so the answer would be:

Have a great day.

Answer:

He spent 35 minutes swimming each day.

Step-by-step explanation:

10x5=50

The multiply by 5 is the numbers of days.

225-50=175

(The 50 minutes subtracted is the time Devon walked)

175 divided by 5 = 35

He spent 35 minutes swimming

Confirm/Check    

35 times 5 =175

( Again, The multiply by 5 is the 5 days.)

175+50= 225

Therefore, He swam 35 minutes each day and walked 10 minutes each day.

He swam 175 minutes in total and walked 50 minutes in total

The number of minutes Devon swam each day is

The word problems must be thoroughly read and understood. Then we can use the given data to make the equations.

He exercised for a total of 225 minutes in the last week.

It is also given that he exercised the amount each day for 5 days.

Therefore, the total number of minutes of exercise per day = 225/5

= 45 minutes.

It is given that he spends 10 minutes everyday walking.

Therefore the total number of time Devon spend swimming = 45 - 10

= 35 minutes

Therefore, we have found that the number of minutes Devon swam each day is 35 minutes.

Answer:

csc(3π/4) = √2

Step-by-step explanation:

∵ csc(3π/4) = 1 ÷ sin(3π/4)

∵ ∠(3π/4) lies on the second quadrant

∴ sin(3π/4) is positive value (according to ASTC Rule)

* ASTC Rule ⇒ (All +ve in 1st quadrant , Sin +ve in 2nd , Tan +ve

                         in 3rd quadrant , Cos +ve in 4th quadrant)

∴ sin(3π/4) = sin(π - α) ⇒ where α is an acute angle

∴ 3π/4 = π - α ⇒ α = π - 3π/4 = π/4

∵ sin²x + cos²x = 1

∵ sin(π/4) = cos(π/4)

∴ 2sin²(π/4) = 1 ⇒ sin²(π/4) = 1/2 ⇒ sin(π/4) = √(1/2)

∴ sin (π/4) = 1/√2  

∴ sin(3π/4) = 1/√2

∴ csc(3π/4) = 1 ÷ 1/√2 = 1 × √2/1 = √2
