Given the length of three sides of a triangle, which is a right triangle?

2 answers:

The aides of a right triangle will always satisfy the Pythagorean relationship ...

   a² + b²= c²

We can take each of these and try it out:

(1) ... 10² + 24² = 100 + 576 = 676
   √676 = <em>26 Yes</em>.

(2) ... 12² + 18² = 144 + 324 = 468
   √468 = 21.6, not 20. <em>No.</em>

(3) ... 15² + 26² = 225 + 676 = 901
   √901 = 30.017 Awfully close. As an engineer, I'll buy this one. <em>Yes.</em>

(4) ... 40² + 50² = 1,600 + 2,500 = 4,100
      √4,100 = 64.03, not 80.<em> No.</em>

A) you can figure this out by testing each with the Pythagorean Theorem

a^2 + b^2 =c^2 (c is the biggest side)

Please help me [Below is the graph of equation y=|x+2|-1. Use this graph to find all values of x such that y<0] IF YOU PUT A

Alchen [17]

Answer:

x ∈ (-3, -1)

Step-by-step explanation:

In the graph, the vertical axis represents the y-value, while the horizontal axis represents the x-value.

y < 0 (y smaller than zero) happens in the region where the graph is below the horizontal axis.

Only by looking at the graph, we can see that y < 0 (the graph is below the horizontal axis) for the values of x in the interval (-3, -1)

Then all the values of x such that y < 0 are:

x ∈ (-3, -1)

-1 1/3 divided by 2 2/5

Crazy boy [7]

Answer:

-5/12

Step-by-step explanation:

-1 times 1 is -1 so -1/3

2 times 2 is 4 so 4/5

-1/3 divided by 4/5

to make it easier we will write like this:

-1/3 times 5/4

-1 times 5=-5

3 times 4=12

so the final answer is -5/12

nonlinear optimization problem is any optimization problem in which at least one term in the objective function or a constraint

Varvara68 [4.7K]

True, the nonlinear optimization problem is an optimization problem in which at least one term in the objective function or a constraint is nonlinear.

Given that,
A statement of nonlinear optimization is given,
We have to determine whether the statement is true or false.

<h3>What is arithmetic?</h3>

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,

Here,

The nonlinear optimization problem is an optimization problem in which at least one term in the objective function or a constraint is nonlinear, is true, Because its basic definition of nonlinear optimization.

Thus, the given statement is true.

Janet and Nadia each play basketball, Nadia has won twice the number of games Janet has, Is it possible for Janet to have won 10

Lapatulllka [165]

Answer:

It is not possible for Janet to have won 10 games.

Step-by-step explanation:

Let be "x" the number of games Janet won.

We know that Nadia has won twice the number of games Janet has and the sum of the games Nadia and Janet have won together is 24.

Then, we express this situation with this equation:

So, let's check if it is possible for Janet to have won 10 games. Substitute into the expression:

Therefore, it is not possible for Janet to have won 10 games.
