Answer:

parallelogram

explanation:

way to know if a quadrilateral is a parallelogram is if opposite sides are actually.

Answer:

I believe the answer is probably parallelogram because it is undetified if it is equivalent on the sides or not. If the sides were equal it would be an isosceles trapezoid and if they weren't it would be a trapezoid. Since there is not enough info about the side legnths of the figure it would more than likely be a parallelogram.

Answer:

-4

Step-by-step explanation:

Find the rate of change for f(x) = x² - 8x + 15 from x = 0 to x = 4

The rate of change is the rate at which a variable changes over a specific period of time.

Averate rate of change: [tex]\frac{f(b)-f(a)}{b-a}[/tex]

First, we need to find the functions for when x = 0 and when x = 4:

For x = 0

f(x) = x² - 8x + 15

f(0) = 0² - 8(0) + 15

f(0) = 0 - 0 + 15

f(0) = 15

For x = 4

f(x) = x² - 8x + 15

f(4) = (4)² - 8(4) + 15

f(4) = 16 - 32 + 15

f(4) = -16 + 15

f(4) = -1

Averate rate of change: [tex]\frac{f(b)-f(a)}{b-a}[/tex]

A = [tex]\frac{f(4)-f(0)}{4-0}[/tex]

A = [tex]\frac{-1-15}{4-0}[/tex]

A = [tex]\frac{-16}{4}[/tex]

A = [tex]-4[/tex]

Therefore, the rate of change from x = 0 to x = 4 is -4.

Question:

Can anyone help been stuck for a while

Answer:

[tex]\frac{5}{11}[/tex]

Step-by-step explanation:

30 regular flavors.

25 watermelon flavors.

Add them both and you get:
55.
Turn that into a fraction:

[tex]\frac{25}{55}[/tex]

The reason the numorator is 25 is because there are 25 watermelon flavors and 55 flavors total.

Find the GCD (or HCF) of numerator and denominator.

The GCD of 25 and 55 is 5.

Divide both the numerator and denominator by the GCD

25 ÷ 5 = 5

55 ÷ 5 = 11

Reduced fraction:

[tex]\frac{5}{11}[/tex]

Therefore, [tex]\frac{25}{55}[/tex] simplified to lowest terms is:

[tex]\frac{5}{11}[/tex]

Therefore, the answer is: [tex]\frac{5}{11} \\[/tex]

use angle addition postulate:

---

1) angle (2x+10) and (x+5) are supplementary, meaning they add up to 180 degrees so

(2x+10)+(x+5)=180

3x+15=180

x=55

---

2) angle (x-30) and x are complementary, meaning they add up to 90 degrees

(x-30)+x=90

2x-30=90

x=60

Answer:

CBD = 63 degrees

Step-by-step explanation:

To find CBD, we must first find the value of x. To do so, we use this equation since CBD and ABC equal 96 degrees:

(6x+27) + (7x-9) = 96
13x+18 = 96
13x+18-18 = 96-18
13x = 78
13x/13 = 78/13
x = 6

Now that we know the value of x, we factor it in to CBD to find its true value:

6x+27
6(6)+27
36+27
= 63 degrees

To check if this answer is correct, we can also find the value of ABC and see if the two values equal 96:

7x-9
7(6)-9
42-9
= 33 degrees

63 + 33 = 96

The answer is correct. CBD = 63 degrees and ABC = 33 degrees.

Answer:

the perimeter, in units of the rectangle is 16x + 20

Step-by-step explanation:

perimeter of a rectangle be is 2(L + B)

p = 2(L + B)

L = 5x + 2

B = 3x + 8

p = 2L + 2B

p = 2(5x + 2) + 2(3x + 8)

p = (10x + 4) + (6x + 16)

p = 10x + 4 + 6x + 16

Collect like terms

p = 10x + 6x + 4 + 16

p = 16x + 20

Answer: 16x+20

Step-by-step explanation:

perimeter of a rectangle is the length of all sides added together.

(3x+8)+(3x+8)+(5x+2) + (5x+2)

combine like terms

16x+20

Answer:

Arc cd = 60 degrees

Step-by-step explanation:

Angle E is an inscribed angle ....inscribed angle will intercept twice as many degrees of arc as the angle measure

  angle measure = 62    twice as many degrees of arc = 124  (b-c-d)

     bc = 64    so   cd  = 60    for the total of 124

The Pythagoras is the sum of the square of two sides is equal to the square of the longest side. Steve is 4 steps in the north.

It is a type of triangle in which one angle is 90 degrees and it follows the Pythagoras theorem and we can use the trigonometry function.

By Pythagoras theorem

[tex]\rm H^2 = P^2+B^2\\\\H^2 = (0.0)^2 + (12-8)^2\\\\H^2 = 4^2\\\\H \ = 4[/tex]

Answer:

P ′(−10, −2), L ′(−5, −4), K ′(−15, 11)

Step-by-step explanation:

The translation vector, ⟨−6,3⟩, can be used to derive a rule for the translation of the coordinates: (x,y)→(x−6,y+3).

Apply the rule to translate each of the three preimage vertices to the image vertices.

P(−4,−5)→P'(−10,−2)

L(1,−7)→L'(−5,−4)

K(−9,8)→K'(−15,11)

Therefore, P'(−10,−2), L'(−5,−4), N'(−15,11) is the translation of the figure with the vertices P(−4,−5), L(1,−7), and K(−9,8), along the vector ⟨−6,3⟩.

Answer:

P ′(−10, −2), L ′(−5, −4), K ′(−15, 11)

K(−9,8)→K'(−15,11)

Therefore, P'(−10,−2), L'(−5,−4), N'(−15,11) is the translation of the figure with the vertices P(−4,−5), L(1,−7), and K(−9,8), along the vector ⟨−6,3⟩.

Answer:

v = -8i - 6j

Step-by-step explanation:

The starting point is (9, 9)

The direction of the vector is the direction of the arrowhead.

The i is the horizontal component.

The j is the vertical component.

Therefore, to go from the start to the end of the line, we need to travel negative 8 units (horizontally) and negative 6 units (vertically).

Therefore, v = -8i - 6j

Answer:

  (b)  v = -8i -6j

Step-by-step explanation:

The unit vectors in the x- and y-directions are i and j, respectively.

The vector v shown in the graph extends from x=9 to x=1, or (1 -9) = -8 units in the x-direction.

It extends from y=9 to y=3, or (3-9) = -6 units in the y-direction.

Represented as a sum of x- and y-vectors, that is ...

Answer:

finding the area:

146

Step-by-step explanation:

You need to break the image up into 3 pieces. the lower big triangle, the middle square, and the top triangle.

the measuremets of the lower big triangle is 14 and 14.
to find the area, we need to do 1/2 *14*14
this equals 98

The measurements of the square is 4,4.
we multiply 4*4 to get 16

The measurements of the top triangle is 8,8.
We find the area by doing 1/2*8*8
We get 32

lastly, we add up all of our solutions.
we do 98+16+32
we get 146.
