What is the the distance between a point at (-3,4) and a point at (2,-5)

zaharov [31]

<h2>Question:-</h2>

What is the distance between a point at (-3,4) and a point at (2,-5) ?

<h2>Solution:-</h2>

Let the two points be A and B .

And, let the distance be P .

Now, the distance P between the point A (-3,4) and the point B (2,-5) is

$\bf P \: = \sqrt{(-3 \: - \: 2)^2 \: + \: (4 \: + \: 5)^2}$

$\implies$ $\bf P \: = \sqrt{(-5)^2 \: + \: (9)^2}$

$\implies$ $\bf P \: = \sqrt{25 \: + \: 81}$

$\implies$ $\bf P \: = \sqrt{106}$

$\implies$ $\bf P \: = \: 10.3$

<h3>The distance between a point at (-3,4) and a point at (2,-5) is 10.3 . [Answer]</h3>

What is the surface area of this rectangular prism

Marina CMI [18]

Answer:

C. $490 \textrm{ units}^{2}$

Step-by-step explanation:

The formula for surface area is

LA + 2B

LA indicated Lateral Area and can be found multiplying perimeter of base by the height.

7 + 7 + 14 + 14 = 42 * 7 = 294

Multiply the LA from above with the area of base times 2.

98 * 2 = 196

294 + 196 = 490, so the surface area of the rectangular prism is 490 units.

What are the coordinates of the y-intercept of the line -3x+2y=6?

m_a_m_a [10]

Answer:

y-intercept: (0,3)

Step-by-step explanation:

To find the y-intercept, we set x to equal 0, giving the equation:

-3(0)+2y = 6

0+2y = 6

y = 3

Find the volume of a cone that has a radius of 5 yards and a

stepan [7]

Answer:

Volume of the cone = $182.91\,yards^3$

Step-by-step explanation:

Radius of the cone = $5\,yards$

Height of the cone = $7\,yards$

Volume of a cone is:

$\pi \times r^2 \times\dfrac{h}{3}\\$

$=3.14\times (5\times 5)\times \dfrac{7}{3} \\\\=3.14\times 25 \times 2.33\\\\=3.14\times 58.25\\\\=182.905\,yards^3$

The Volume of the cone is : $182.91\,yards^3$
