Mathematics
1 answer:
Serggg [28]3 years ago
3 0

Step-by-step explanation:

1. No: angles add to more than 180 deg.

2. Yes: each side's length is between the sum and difference of the lengths of the other two sides.

3. No: not every side's length is between the sum and difference of the lengths of the other two sides.

4. Yes: for example, place the 50 deg angle between the two given sides. Another side will then make the triangle.

5. Yes: for example, use 3 cm as the short leg in a 30-60-90 right triangle.

What is one half of negative five eights
Brrunno [24]

five eighths means 5/8

negative five eighths means -5/8

one half means 1/2

so 1/2 of negative five eighths means multiply 1/2 with -5/8

\frac{1}{2} * \frac{-5}{8}

multiplying numerators together and denominators together,

\frac{1*(-5)}{2*8}

So answer is -5/16

What is the image point of (5,-6)(5,−6) after the transformation r_{\text{y-axis}}\circ T_{-4,0}r
Brums [2.3K]

The <em>image</em> point of <em>P(x,y) =</em><em> (5, -6)</em> after applying a <em>horizontal</em> reflection is <em>P'(x,y) =</em><em> (1, -6)</em>.

<h3>How to apply a rigid transformation in a point on a Cartesian plane</h3>

In geometry, a <em>rigid</em> transformation is a transformation applied onto a <em>geometric</em> object such that <em>Euclidean</em> distance in every point of it is conserved. Translations are examples of <em>rigid</em> transformations and are defined by this formula:

<em>P'(x,y) = P(x,y) + T(x,y)</em>   (1)

Where:

  • <em>P(x,y)</em> - Original point
  • <em>T(x,y)</em> - Translation vector
  • <em>P'(x,y)</em> - Image point

If we know that <em>P(x,y)</em><em> = (5, -6)</em> and <em>T(x,y)</em><em> = (-4, 0)</em>, then the image point is:

<em>P'(x,y) = (5, -6) + (-4, 0)</em>

<em>P'(x,y) = (1, -6)</em>

The <em>image</em> point of <em>P(x,y) =</em><em> (5, -6)</em> after applying a <em>horizontal</em> reflection is <em>P'(x,y) =</em><em> (1, -6)</em>. \blacksquare

<h3>Remark</h3>

Statement is incorrect and poorly formatted. Correct form is shown below:

<em>What is the image point of </em><em>(x, y) = (5, -6)</em><em> after the transformation of translating horizontally the point -4 units to the y-axis?</em>

Kevin and randy muise have a jar containing 69 ​coins, all of which are either quarters or nickels. The total value of the coins
Readme [11.4K]

Let us assume number of quarters = q.

Let us assume number of nickels = n.

Total number of coins = 69.

We can setup first eqation,

Number of quarters + number of nickels = 69.

q + n = 69 -------------- equation(1).

Total value of all the coins = $9.05

We can setup second equation as,

0.25*number of quarters + 0.05*number of nickels  - $9.05.

0.25q + 0.05n =9.05   ........................equation(2).

We got two equations of a system of equation.

Let us apply substitution mehod of solving system of linear equations.

Solving first equation q+n=69 for n.

Adding q on both sides of the equation, we get

q-q+n = 69-q.

n= 69-q.

We need substitute n=69-q in second equation 0.25q + 0.05n =9.05.

0.25q +0.05(69-q) = 9.05

Distributing 0.05 over (69-q).

0.25q +0.05*69 -0.05*q =9.05.

0.25q +3.45 -0.05q =9.05

Combining like terms 0.025q -0.05q, we get

0.20q +3.45 =9.05

Subtracting 3.45 from both sides.

0.20q +3.45-3.45 =9.05-3.45

0.20q = 5.6

Dividing both sides by 0.20

0.20q/0.20 = 5.6/0.20

q = 28.

Plugging q=28 in equation(1)

q+n =69    => 28 +n =69

Subtracting 28 from both sides, we get

28-28 +n =69-28.

n = 41.

Therefore, number of quarters 28 and number of nickels 41.
