Her screen is a triangle duh

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.

Identify the translation of the figure with the vertices P(−4,−5), L(1,−7), and K(−9,8), along the vector <−6, 3>.

Answers:

P ′(2, −8), L ′(7, −10), K ′(−3, 5)
P ′(−10, −8), L ′(−5, −10), K ′(−15, 5)
P ′(2, −2), L ′(7, −4), K ′(−3, 11)

Answers

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)

Step-by-step explanation:

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⟩.

What is an equation of the circle with center (-5,4) and a radius of 7?

(2) (x - 5)2 + (y + 4)² = 49
(3) (x + 5)² + (y — 4)² = 14
(4) (x + 5)² + (y - 4)² = 49

Answers

Answer:

Option D

Step-by-step explanation:

Given:

Center point: (-5, 4)Radius: 7

Formula:

Equation of circle: (x - h)² + (y - k)² = r²

[Where (h, k) is the center point and "r" is the radius of the circle]

Substitute the coordinates of the center point in the formula:

Given center point: (-5, 4)

∴ x-coordinate of center point (h) = -5; y-coordinate of center point (k) = 4

⇒ (x - h)² + (y - k)² = r²⇒ [x - (-5)]² + [y - 4]² = r²

Substitute the radius in the formula:

Given radius: 7

⇒ [x - (-5)]² + [y - 4]² = r²⇒ [x - (-5)]² + [y - 4]² = (7)²

Simplify both sides of the equation:

⇒ [x + 5]² + [y - 4]² = (7)(7)⇒ [x + 5]² + [y - 4]² = 49  (Option D)

Therefore, Option 4 is correct.

Volume is the measure of 3 dimensional space. The volume of the considered cylinder whose radius is of 3 units, and height of 6 units is V = 54π cubic units.

What is the volume of a cylinder?

Suppose that the radius of considered cylinder be 'r' units.

And let its height be 'h' units.

Then, its volume is given as:

For this case, we're specified that:

Radius of the considered cylinder = r = 3 unitsThe height of the considered cylinder = h=  6 units.

Thus, the volume of this cylinder is:

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.

Which of the following represents the linear form of v?



v= -6i -8j


v= -8i-6j


v= 6i +8j


v= 8i +6j

Answers

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 ...

Find the rate of change for f(x)=x^2-8x+15 from x=0 to x=4

Answers

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.

Hope this helps!
