Point P=(-3,1). The point P is rotated 270°. Reflected across y=x. The given image is obtained by rotating a preimage by 270 degrees clockwise and using its coordinates point P"=(3,1).

Given that,

Point P=(-3,1)

The point P is rotated 270°.

Reflected across y=x.

The reflection of (x, y) across the line y = x results in (y, x)

Across the line y = x, P(-3, 1) is reflected (1, -3)

The given image is obtained by rotating a preimage by 270 degrees clockwise and using its coordinates (x, y) is (-y, x)

The given image is produced by rotating the preimage, P, by 270 degrees clockwise. Its coordinates are P = (1, -3) is (3, 1)

Therefore, point  P"=(3,1)

if this trapezoid is to scale, then the scale factor between the shortest and longest side is 1.5

so, that means that 1.5(2x+6) = 4x+2

so, your equation becomes 3x+9 = 4x+2

if you subtract 2 from each side, you get 3x+7 = 4x

meaning that x = 7

Step-by-step explanation:

15 - 2.5x = 40 ( isolate the term in x by subtracting 15 from both sides )

- 2.5x = 40 - 15 = 25 ← Step 1

divide both sides by - 2.5

Step-by-step explanation:

The function f(x) = x^4 + 4/x^2 + 1 is an even function

The equation of the function is given as

f(x) = x^4 + 4/x^2 + 1

Calculate f(-x)

So, we have

f(-x) = (-x)^4 + 4/(-x)^2 + 1

Evaluate the exponents

f(-x) = x^4 + 4/x^2 + 1

Calculate -f(x)

So, we have

-f(x) = -[x^4 + 4/x^2 + 1]

Evaluate the product

-f(x) = - x^4 + 4/x^2 + 1

From the above computations, we have

f(x) = f(-x)

This represents an even function

Hence, the function f(x) = x^4 + 4/x^2 + 1 is an even function

Answer: Murder is a sin

Step-by-step explanation:

Total time taken by Andrew and bob is 2hr.

given, time taken by Andrew to paint the room = 3hrtime taken by bob to paint the room =6hr rate of Andrew as x =1/3.

rate of bob as y=1/6x+y=1/3+1/6=1/2

total time taken by Andrew and bob =1/x + y      

                                                             =1/1/3+1/6

                                                             = 2hr.

therefore total time taken by Andrew and bob is 2 hr.

The formula for time is given as [Time = Distance ÷ Speed]. To calculate the distance, the time formula can be molded as [Distance = Speed × Time].

To get the total decimal hours we use the formula: h = hours + (minutes / 60) + (seconds / 3600). To get the total decimal minutes we use the formula: m = (hours * 60) + minutes + (seconds / 60).

Answer:

The most common interval is 10 to 14.99 $ with 11 items

Step-by-step explanation:

See attached for details.

$10.00-$14.99 is the most common interval of dinner prices.

To find the most common interval of dinner prices,

Organize the data into the specified intervals and then count the occurrences in each interval.

Here are the intervals:

1. $5.00-$9.99

2. $10.00-$14.99

3. $15.00-$19.99

4. $20.00-$24.99

5. $25 and up

Now, let's categorize the dinner prices from the given list into these intervals:

1. $7.50, $7.98, $6.50, $8.25, $8.75, $9.00, $9.99 (7 prices)

2. $10.00, $12.00, $12.98, $12.99, $11.50, $13.50, $11.25, $13.00, $12.50 (9 prices)

3. $14.00, $14.75, $15.00, $17.49, $16.00, $17.99 (6 prices)

4. $21.00, $20.00, $22.00 (3 prices)

5. $26.00, $28.50, $25 and up (3 prices)

Now, let's see which interval has the highest number of prices.

It appears that the second interval, $10.00-$14.99, has the most prices (9 prices), making it the most common interval of dinner prices.

Hence, $10.00-$14.99 is the most common interval of dinner prices.

Step-by-step explanation:

Answer:

This answer is D

Step-by-step explanation:

Answer:

The unit rate = 2 dollars / per pineapple

Point A(7, 14) indicates that the value of 14 pineapples is 7 dollars.

Step-by-step explanation:

The unit rate represents the slope of the line.

It means the slope is often termed as a ratio, which could be expressed as a unit rate found at the point on the graph with the given ordered pairs.

Let us take two points that lie on the graph to determine the unit rate (or slope)

unit rate = slope = y₂-y₁ /  x₂-x₁

                            = 4-2 / 2-1

                            = 2/1

                             = 2

Thus, the unit rate = 2 dollars / per pineapple

The location of point A is (7, 14)

Answer:

  18 cm

Step-by-step explanation:

Consider right triangle PCA.

The length PC is the hypotenuse of that triangle. It is also the radius of the circle: 15 cm.

The length AC is AB -CB = (27 -15) cm = 12 cm.

The length AP can be found from the Pythagorean theorem:

  AP² +AC² = PC²

  AP² = PC² -AC² = (15 cm)² -(12 cm)² = (225 -144) cm² = 81 cm²

  AP = √(81 cm²) = 9 cm

Since A is the midpoint of PQ, the length of PQ is double the length of AP:

  PQ = 2·AP = 2·9 cm

  PQ = 18 cm

Answer:

We have slope m: [tex]m=-\frac{1}{6}[/tex]

We need to find value of b (y-intercept)

In the given figure , two sides of the triangle are equal , so it is isosceles triangle . So , as we know that in an isosceles triangle equal side's opposite answers are also equal . Now ,

=> x = 75°

Hence , x = 75°

Using the same property which we used in the above problem ,

• x = x

Now using angle sum property of triangle ,

=> x + x + 40° = 180°

=> 2x + 40° = 180°

=> 2x = 180° - 40°

=> 2x = 140°

=> x = 140° / 2

=> x = 70°

Hence , x = 70° .

Answer:

The ans to the first question would be 75, Coz....

It's an Isosclese triangle, as both sides are equal [The two lines on the triangle indicate that its equal]

So,the angle given is 75 degrees, the other angle would be 75 degrees too.

For the second question-

The same rule applies here, the triangle shown is an isosclese triangle,so the angle x & the angle opposite to x should be equal [The angle opposite or next to angle x is blank, so lets just call it y]

The equation of a triangle goes-

The angles of a triangle add upto 180

So 40+x+y=180

180-40 will give the sum of both angle x & y

180-40=140 [Now we know that x+y=140, we also know that both angles have the same value, so basically they're equal]

this means that we can divide 140 equally into two parts to disturbute the value to both x & y

140/2=70 degrees

So, the ans of x=70 [y is also 70, but the question doesnt  ask for it]
