Answer:

5

Step-by-step explanation:

Pythagoras's theorem dictates that  a squared + b squared  = c squared when talking about sides on right angled triangles with a and b being flat sides and c being the hypotenuse which gives us the forumula below

3 squared + 4 squared = 25 route 25 = 5

Answer:

Step-by-step explanation:

Distance=\sqrt{(x_2-x_1)^{2}+(y_2-y_1)^{2}}\\\\d_{3}=\sqrt{(2-[-1])^{2}+(0-4)^{2}}\\\\ =\sqrt{(2+1)^{2}+(-4)^{2}}\\\\ =\sqrt{(3)^{2}+(-4)^{2}}\\\\=\sqrt{9+16}\\\\ =\sqrt{25}\\\\ =5

Please Solve 8=1/3(a+5)
e-lub [12.9K]

Answer:

a = 19

Step-by-step explanation:

Given the equation of:

\displaystyle{8 = \dfrac{1}{3}(a+5)}

First, multiply both sides by 3. That will clear the denominator which makes it easier to solve for a variable:

\displaystyle{8 \cdot 3= \dfrac{1}{3}(a+5) \cdot 3}\\\\\displaystyle{24= a+5}

Subtract both sides by 5 to isolate the variable:

\displaystyle{24-5=a+5-5}\\\\\displaystyle{19=a}

Therefore, the value of a is 19.

Write the equation for a parabola with a focus at (1,2)(1,2)left parenthesis, 1, comma, 2, right parenthesis and a directrix at
Tanya [424]

Answer:

  y = -1/8(x -1)² +4

Step-by-step explanation:

The equation of a parabola can be written from focus and directrix using the form ...

  y = 1/(4p)(x -h)² +k

where p is the distance from vertex to focus, and (h, k) is the vertex.

The vertex-focus distance is half the distance from the directrix to the focus. Here, that is ...

  p = (2 -6)/2 = -4/2 = -2

The vertex is halfway between the focus and directrix on the same vertical line, so has coordinates ...

  (h, k) = ((1, 2) +(1, 6))/2 = (1, 4)

__

Using these values of p and (h, k), we find the equation of the parabola to be ...

  y = 1/(4(-2))(x -1)² +4

  y = -1/8(x -1)² +4

_____

<em>Additional comment</em>

You can check the graph by considering the definition of a parabola: each point on the curve is equidistant from the focus and the directrix. This is easily verified for points on the horizontal and vertical lines through the focus. For example, point (5, 2) is 4 units from the focus, and 4 units from the directrix.

Three packs of markers cost $9.00 less than 5 packs of markers. How
serg [7]
One pack is $4.50.

To make it simpler with no equations, There are 2 packs of markers in-between 3 packs and five packs.
So, $9 divided by 2 packs is 4.5$,
And to prove this scenario right,
3 packs= $13.5. (3•4.5)
5 packs= $22.5. (5•4.5)
So between 5 packs and 3 packs,
There is a difference of 9 dollars,
Hence 3 packs of markers at $13.5,
5 packs is $22.5, so that is $9 less
Than 5 packs of markers.
Therefore one pack of markers is $4.50, by dividing 22.5 by 4.5 or 13.5 by 4.5 after figuring out the previous.
