Pythagorean theorem

Mathematics
1 answer:
Paladinen [302]3 years ago
7 0

Answer:

x = 3

x + 3 = 6

√45

Step-by-step explanation:

the general theorem is

a^2 + b^2 = c^2

Givens

a = x

b = x + 3

c = √45

Solution

x^2 + (x + 3)^2 = (√45)^2          Substitute

x^2 + x^2 + 6x + 9 = 45             Expand the brackets. Square √45  

2x^2 + 6x + 9 = 45                    Subtract 45 from both sides

2x^2 + 6x - 36 = 0                     Divide by 2

x^2 + 3x - 18 = 0                        Factor

(x + 6)(x - 3) = 0                         x+ 6 has no meaning in the real world.

x - 3 = 0

x = 3                                          

Answer

a) 3

b) 6

c) √45

Find the area of a circle whose circumference is 31.4 centimeters. approximate as 3.14
hoa [83]

To find the circumference of a circle you multiply pi (3.14) by the diameter ad to find the area you multiply pi (3.14) times the radius squared

Since the circumference is 31.4 divide that by pi to find the diameter which is 10

The radius of a circle is half of the diameter, so for this circle the radius is 10 / 2 = 5

Take the radius and square it : 5^2 = 25

Then multiply the squared radius by pi (3.14) to find the are : 25 * 3.14 = 78.5

So the area of this circle is 78.5 centimeters squared

Hope this helps! Mark as Brainliest please! :)))

Match the following items.
Misha Larkins [42]

Based on the points on the graph, the correct matches are:

  • A - (-4, -2).
  • B - .(2, -4)
  • C - (4, -2).
  • D - (2, 5)
  • E - (-1, 1)
  • F - (-5, 0)
  • G - (4, 2)
  • H - (0, -5)

<h3>How are points located on a graph?</h3>

To find a point, you need to look at the x-axis first and then the y-axis.

Find where the point is located on the x-axis, and then look for where the point intersects with the y-axis point.

For instance, the point A is located at (-4, -2) so look at the -4 point on the x axis, then go down to the -2 point on the y-axis. You'll find point A.
