The distance between two points:

\large  \boxed{ \sqrt{(x_2 - x_1)^{2} +  {(y_2 - y_1)}^{2}  } }

From the graph, the given points are (-3,1) and (5,-4). Substitute the points in as we get:

\large{d =  \sqrt{ {( - 3 - 5)}^{2} +  {(1 + 4)}^{2}  } } \\  \large{d =  \sqrt{ { (- 8)}^{2}  +  {5}^{2} } } \\  \large{d =  \sqrt{64 + 25} \longrightarrow  \sqrt{89} }

Hence the distance between two points is √89.

Answer

  • √89

What is (-33x-78)+(5x8x9x10)divided by9.75
kherson [118]

Answer:

<em>6,174</em>

Step-by-step explanation:

(-33 * - 78) + (5 * 8 * 9 * 10)

Remove the brackets:

-33 * - 78 + 5 * 8 * 9 * 10

Solve like so:

-33 * - 78 = 2,574

5 * 8 * 9 * 10 = 3,600

(2,574) + (3,600)

2,574 + 3,600 = 6,174

If y is directly proportional to x square and y equal 1/8 when x = 1/2 what is the positive value of x when y it was 9/2?
mojhsa [17]

Answer:

d

Step-by-step explanation:

Given y is directly proportional to x² then the equation relating them is

y = kx² ← k is the constant of proportion

To find k use the condition y = \frac{1}{8} when x = \frac{1}{2}, then

\frac{1}{8} = k(\frac{1}{2} )² = \frac{1}{4} k ( multiply both sides by 8 )

1 = 2k ( divide both sides by 2 )

k = \frac{1}{2}

y = \frac{1}{2} x² ← equation of proportion

When y = \frac{9}{2} , then

\frac{9}{2} = \frac{1}{2} x² ( multiply both sides by 2 )

9 = x² ( take the square root of both sides )

x = ± \sqrt{9} = ± 3

with positive value x = 3 → d

An electrician needs to run a cable from the top of a 40​-foot tower to a transmitter box located 30 feet away from the base of
grin007 [14]
The cable should be 50 feet.

If you draw the picture, you will see that you have a right triangle.

Let's just use the Pythagorean Theorem to find the hypotenuse (or cable).

30^2 + 40^2 = c^2
2500 = c^2
50 = c
