Answer:

Step-by-step explanation:

25 and 27 are not perfect squares so they can not be the answer.

36 and 81 are both multiples of 3, but only 81 is not even, so the answer is 81

That's the isosceles right triangle, one of the two cliche triangles students are expected to learn. The sides of the 45°/45°/90° triangle are in the ratio 1:1:√2.

So v= 3√2 (the two legs are equal) and hypotenuse u = √2 × v = 6.

A new curved screen TV costs $3,508.80. A family makes a down payment of $450 and pays off the balance in 24 equal monthly payme

77julia77 [94]

Answer:

$127.45

Step-by-step explanation:

First, subtract 450 from 3,508.80:

3,508.80 - 450 = 3058.8

Then, divide this by 24 to find the monthly payment:

3058.8/24

= 127.45

So, the monthly payment was $127.45

Use the Well-Ordering Principle to prove that given a > 0, a^n > 0 for every positive integer n

pishuonlain [190]

Answer:

Following are the answer to this question:

Step-by-step explanation:

Given value:

$\to x > 0$

$\to S= { n\varepsilon N : x^n \leq 0 } \\\\ s \neq \phi \\\\ \to x^n \leq 0\\$

$\to x^{n-1} x\leq 0\\\\ \to x>0 = x^{n-1} \leq 0 \\\\\to n-1 \varepsilon s \\ \ \ _{where} \ \ n-1 < n \\\\\to s= \phi \\\\\to \hence x^n > 0 \\$

A helicopter floats 120m above a helipad, a dog is 85m from the helipad, if the dog could fly, how far would it have to fly to g

suter [353]

<em>If the dog could fly, it would need to fly 147 meters to catch the helicopter</em>

This is a rather easy and straightforward question. We are going to solve it using Pythagoras theorem. We can interpret the question to be in a triangle where the height of the helicopter above the helipad and away from the dog is the right angle. This also means that the distance needed, between the dog and the helicopter is the hypotenuse.

Using pythagoras theorem, we have

120² + 85² = c²

c² = 14400 + 7225

c² = 21625

c = $\sqrt{21625}$

c = ±147 meters.

Since distance cant be in the negative, our answer is 147 m
