Select the correct answer.

Damm [24]

Answer:

D (I think?)

Step-by-step explanation:

It's neither a nor b because neither of them would work if you plug in o for x.

The reason I think it's D and not C is because it goes up by 10,000 x (1.1)^x

Just not sure because because of how the question was asked. Hope this helps

Which side lengths form a right triangle? Choose all answers that apply: Choose all answers that apply: (Choice A) A \sqrt4, 10,

Vika [28.1K]

Answer:

(C)

Step-by-step explanation:

In order to find whether the given side lengths form a right triangle or not, we must show that it satisfies the Pythagoras theorem.

A. $\sqrt{4}$ , 10 and 116

According to Pythagoras theorem,

⇒ $(116)^2=4+100$

⇒ $13456=104$

which does not satisfy the condition, therefore these side lengths do not form a right triangle.

B. 3,6 and 8

According to Pythagoras theorem,

⇒ $(8)^{2}=(3)^2+(6)^2$

⇒ $64=9+36$

⇒ $64=45$

which does not satisfy the condition, therefore these side lengths do not form a right triangle.

C. 30, 40 and 50

According to Pythagoras theorem,

⇒ $(50)^{2}=(30)^2+(40)^2$

⇒ $2500=900+1600$

⇒ $2500=2500$

which satisfies the condition, therefore theses side lengths form right triangle.
