Rewrite the function by completing the square. f(x)=x^2+16x-46

Answers

Answer:

[tex]f(x)=(x+8)^{2}-110[/tex]

Step-by-step explanation:

Completing the square is a multi-step process that involved rewriting an equation such that it has a factored term, a coefficient, and a constant. First, group the equation, then add a term such that the grouped part of the equation can be simplified, then balance the equation, finally simplify and factor the equation.

[tex]f(x)=x^{2} +16x - 46\\[/tex]

Group;

[tex]f(x)=(x^{2}+16)-46[/tex]

Add in a term that makes the grouped part of the equation a perfect square, this can be done by dividing the linear term by 2, then balancing the equation;

[tex]f(x)=(x^{2}+16x+64)-46-64[/tex]

Simplify, factor;

[tex]f(x)=(x+8)^{2} - 110[/tex]

Step-by-step explanation:

The equation to solve the Pythagorean Theorm looks like this-

a²+b²=c²

So, lets use it to find the hypotenuse-

5²+12²=c²

(5*5)+(12*12)=(c*c)

25+144=c²

(25+144=169)

Now, solve:

plug x = 24 + y into x + y = 180

24 + y + y = 180

24 + 2y = 180

2y = 156

y = 78

Now, plug this back into the equation x = 24 + 78

x = 102

Answer:

x= 102

y= 78

Given the side measurements, classify the triangle as acute, obtuse, right, or not a triangle. 8, 12, 14

Answers

Answer: It's an acute triangle.

Step-by-step explanation: I have the same problem, and I tried each choice, acute was the correct answer

The triangle with side lengths 8, 12, 14 is an obtuse triangle.

What is Triangle?

A triangle is a three-sided polygon that consists of three edges and three vertices.

To determine whether the triangle is acute, obtuse, or right, we can use the Pythagorean theorem, which states that in a right triangle, the sum of the squares of the lengths of the two shorter sides is equal to the square of the length of the longest side.

8² + 12² = 64 + 144 = 208

14² = 196

Since 208 is greater than 196, we can see that the triangle does not satisfy the Pythagorean theorem. Therefore, the triangle is not a right triangle.

Since the longest side is 14 and the sum of the squares of the two shorter sides is less than the square of the longest side, we can conclude that the triangle is obtuse.

Therefore, the triangle with side lengths 8, 12, 14 is an obtuse triangle.
