HELP 5 STAR + THANKS What series of transformations from △ABC to ​ △DEF ​ shows that △ABC≅△DEF ? a reflection across the y-axis

followed by a translation of 1 unit right and 2 units up a clockwise rotation of 90° about the origin followed by a translation of 4 units right and 4 units up a reflection across the x-axis followed by a translation of 1 unit right and 1 unit down a reflection across the line y = x followed by a positive rotation of 270° about the center

In the given triangle, the verteces are A(-4, 1), B(-6, 5), C(-1, 2).
A refrection across the x-axis will result in A'(-4, -1), B'(-6, -5), C'(-1, -2)
A translation of 1 unit to the right will result in A"(-3, -1), B"(-5, -5), C"(0, -2)
A translation of 1 unit down will result in A"'(-3, -2), B"'(-5, -6), C"'(0, -3) which corresponds to points DEF.
Therefore, the series of transformation required to transform ABC to DEF are <span>a reflection across the x-axis followed by a translation of 1 unit right and 1 unit down.</span>

Find (fog)(x).
azamat

Answer:

\large\boxed{(f\circ g)(x)=-15x+14}

Step-by-step explanation:

f(x)=-5x+9\\\\g(x)=3x-1\\\\(f\circ g)(x)=f\bigg(g(x)\bigg)-\text{put}\ x=g(x)\ \text{in}\ f(x):\\\\(f\circ g)(x)=-5(g(x))+9=-5(3x-1)+9\qquad\text{use the distributive property}\\\\=(-5)(3x)+(-5)(-1)+9=-15x+5+9=-15x+14

Bev writes three numbers on a piece of paper.
Studentka2010 [4]
<h2>Question </h2>

Bev writes three numbers on a piece of paper.

  • The first number is even.
  • The second number is odd.
  • The third number is even.

Which set of numbers could Bey have written?

14, 18, 16

19, 12, 15

12, 17, 14

10, 15, 19

<h2>Answer:</h2>

12, 17, 14

<h2>Step-by-step explanation:</h2>

14, 18, 16  = 14(even), 18(even), 16(even) = <em>cannot be the correct answer</em>

19, 12, 15  = 19(odd), 12(even), 15(odd) = <em>cannot be the correct answer</em>

12, 17, 14  = 12(even), 17(odd), 14(even) = is the correct answer

10, 15, 19  = 10(even), 15(odd), 19(odd) = <em>cannot be the correct answer</em>

A plane flies 452 miles north and then 767 miles west. What is the magnitude and direction of the plane's resultant vector?
pshichka [43]

<u>Answer:</u>

The plane's resultant vector is 890.3 miles, at an angle of 59.5° west of north.

<u>Step-by-step explanation:</u>

• To find the magnitude of the resultant vector, we have to use Pythagoras's theorem:

\boxed{a^2 = b^2 + c^2}

where:

a ⇒ hypotenuse (= resultant vector = ? mi)

b, c ⇒ the two other sides of the right-angled triangle (= 452 mil North, 767 mi West).

Using the formula:

resultant² = 452^2 + 767^2

⇒ resultant =  \sqrt{452^2 + 767^2}

⇒ resultant = 890.3 mi

• To find the direction, we can find the angle (labeled <em>x</em> in diagram) that the resultant makes with the north direction:

tan (x) =\frac{767}{452}

⇒ x = tan^{-1} (\frac{767}{452} )

⇒ x = \bf{59.5 \textdegree}

∴ The plane's resultant vector is 890.3 miles, at an angle of 59.5° west of north .
