Answer:

True is the correct answer to the given question.

Step-by-step explanation:

Euclidean geometry is the mathematical technique that are discovered by the Greek mathematician Euclid of the Alexandria .In the In the 19th century fifth postulate of the euclidean geometry are created.

The Euclid approach is to presume the limited number of the influential theoretical axioms as well as to conclude several other proposals.

The main objective of fifth postulate of euclidean geometry is to implement the properties of geometry like points ,etc without the use of coordinate geometry .

If the length of the legs of a right triangle are 18 and 34, what is the length of the hypotenuse? Round your

oksano4ka [1.4K]

Answer:

<h2>The answer is 38.5</h2>

Step-by-step explanation:

Since we have been given the legs of the right angled triangle we can use Pythagoras theorem to find the hypotenuse

That's

${h}^{2} = {b}^{2} + {c}^{2}$

where

h is the hypotenuse

The legs of the triangle are 18 and 34 so the hypotenuse is

${h}^{2} = {18}^{2} + {34}^{2}$

$h = \sqrt{324 + 1156} \\ h = \sqrt{1480} \\ h = 2 \sqrt{370}$

h = 38.47076

We have the final answer as

<h3>h = 38.5 to the nearest tenth</h3>

Hope this helps you

a 2.5kg mass is held above the ground and has 50 J of gravitational potential energy. the mass is then dropped and accelerates t

SVETLANKA909090 [29]

Answer:

$6.3m/s$

Step-by-step explanation:

<u>Note: We will take g as 9.8 in this question.</u>

The two equations we will use for this questions are:

$G.P.E = mgh$ , m = mass, g = acceleration due to gravity

and the SUVAT equation: $v^2=u^2+2as$

First, let's start out by finding the height from which the object is being dropped. We can do this by using the gravitational potential energy formula.

Subbing the values we have:

$50 = 2.5*9.8*h$

$h = 2.04$ - re-arranging for the height we get a height of 2.04.

Now we will use the SUVAT equation. Let's set out the variables we have:

$S=2.04\\U=0\\V=?\\A=9.8\\T=N/A$

U (initial speed) is equal to 0 because we are dropping the object from rest. Acceleration is equal to 9.8 as that is the acceleration due to gravity. The displacement (S) is the height we just worked out.

Now let's put them into one of the SUVAT equations:

$v^2=u^2+2as$

$v^2=(0)^2+2(9.8)(2.04)$

$v^2=39.984$

$v=6.3 m/s$

Laura wrote and solved the following expression to find the total number of beads Lina has if there are 6 beads in each packet.

bulgar [2K]

<h3>The number of beads lina has is 31</h3><h3>Laura made a mistake by adding the constant 7 and variable 4b</h3>

<em><u>Solution:</u></em>

Given that,

Laura wrote and solved the following expression to find the total number of beads Lina has

There are 6 beads in each packet

7+4b = 11b

= 11(6)

=66

From given,

Lina has a total of 7 + 4b beads

Given that, There are 6 beads in each packet

Substitute b = 6

7 + 4(6)

Simplify

7 + 24

Add

Thus, she has a total of 31 beads and not 66 beads

Laura made a mistake by adding the constant 7 and variable 4b

But a constant and variable cannot be added

Two skateboarders start a race at the same time skateboarder A travels at a steady rate of 15 feet per second skateboarder B tra

Dmitriy789 [7]

Answer:

Step-by-step explanation:

Relative speed can play a major role in creating distance between two bodies. If the relative speed between two bodies is 0, then both the bodies are moving in the same direction with a similar speed. Thus, After 4 minutes, 1680 feet farther will Skateboarder B have traveled.

Skateboarder A travels at a steady rate of 15 feet per second.

Skateboarder B travels at a steady rate of 22 feet per second.

We need to determine that after 4 minutes, how much farther will Skateboarder B have traveled.

The formula for finding the distance travelled by anybody is represented below

Time is given that is 4 minutes which means 240 seconds.

Thus,

Distance travelled by skateboarder A

Distance travelled by skateboarder B.

Therefore, the separation of the distance between both the skateboarders is 5280 - 3600 = 1680.

Thus, After 4 minutes, 1680 feet farther will Skateboarder B have traveled.
