Answer 1

Answer:

[tex]m = 3 \sqrt{12} [/tex]

[tex]n = 6[/tex]

Step-by-step explanation:

n=1/2 of 12 according to the rule:

right triangle the side opposite the 30 degree angle is half the length of the hypotenuse.

so n=12/2=6

and now we will need Pythagorean theorem : the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse (the side opposite the right angle)—or, in familiar algebraic notation, a2 + b2 = c2.

so

[tex] {m}^{2} + {n}^{2} = {12}^{2} [/tex]

now lets put numbers on formula

[tex] {m}^{2} + {6}^{2} = {12}^{2} [/tex]

from this formula m=

[tex]m = \sqrt{ {12}^{2} - {6}^{2} } = \sqrt{144 - 36} = \sqrt{108} = 3 \sqrt{12} [/tex]

Find the composition of transformations that map ABCD to EHGF. Reflect over the -axis, then translate (x+ ,y+)

Answers

9514 1404 393

Answer:

  (x+ (-4), y+ (-4))

Step-by-step explanation:

After point D is reflected across the y-axis, its coordinates are ...

  D(-1, 2) ⇒ D'(1, 2)

This is the point that gets translated to F(-3, -2). The translation is ...

  F -D' = (-3, -2) -(1, 2) = (-3-1, -2-2) = (-4, -4)

Then the translation rule is ...

  (x, y) ⇒ (x+(-4), y+(-4))

     2y = 2x + 8         {Divide the equation by 2}

How many right angles need to be put together to make:
a.) 360 degrees?
b.) 180 degrees?
C.) 270 degrees?
d.) A straight angle?

Answers

Answer:

A 180° angle is called a straight angle. Angles such as 270 degrees which are more than 180 but less than 360 degrees are called reflex angles. A 360° angle is called a complete angle.

Answer:

A. 4

B. 2

C. 3

D. 2

Step-by-step explanation:

Multiplication!!! Always remember that a right angle is 90 degrees, also a straight angle is 180 degrees..

Remember like this:

90 x 1 =90

90 x 2 =180

90 x 3 = 270

90 x 4 = 360

A tunnel is in the shape of a parabola.if the tunnel is 40 feet wide and has a maximum height of 12 feet. write the equation of the quadratic function that represents the tunnel(let the axis of symmetry be the y-axis)​

Answers

9514 1404 393

Answer:

  y = -0.03x² +12

Step-by-step explanation:

For "tunnel" or "arch" or "bridge" problems, I like to start with the expression ...

  y = 1 - x²

It has a height of 1 and intersects the x-axis at ±1. This can be scaled to give the appropriate height and x-intercepts.

We want the x-intercepts to be ±20, so we can scale this horizontally by a factor of 20:

  y = 1 -(x/20)²

We want the height to be 12, so we can scale it vertically by a factor of 12:

  y = 12(1 -(x/20)²

  y = 12 -12(x²/400)

  y = -0.03x² +12
