<span>I, only. The first situation is a linear function, growing the same amount every day. (Constant slope) The other two are exponential functions with the amount changing from interval to interval. Even if the percentage remains the same.</span>

Determine if a triangle with side lengths 8, 14, and 15 is acute, right, or obtuse
asambeis [7]

Answer:

Acute

Step-by-step explanation:

The Converse of the Pythagorean Theorem states that:

  • If a^2+b^2 > c^2 then the triangle is acute.
  • If a^2+b^2 < c^2 then the triangle is obtuse.
  • If a^2+b^2 = c^2 then the triangle is right.

The side lengths 8, 14, and 15 are given. We can assume the hypotenuse (or c) is the longest side length, so it is 15.

  • c = 15

It doesn't matter which order of the numbers are plugged in for a and b, so a and b will be 8 and 14.

  • a = 8
  • b = 14

Now we have to add a^2 and b^2 to see if the sum is greater than, less than, or equal to 15 (c).

  • a^2 + b^2
  • 8^2 + 14^2

Calculate the rest of the problem.

  • 8^2=64 \newline 14^2=196
  • 64+196=260

We have to find what 15^2 is before we can make a decision using the Converse of the Pythagorean Theorem.

  • 15^2=225

260 (a^2+b^2) is greater than 225 (c^2). This means that the triangle is acute because a^2+b^2>c^2.

What is the slope of the line that passes through the points (5,-25) and (10, -15)
Salsk061 [2.6K]
<h2>Answer:</h2>

All you need to do is use the slope formula: y₂ - y₁/x₂ - x₁.

\frac{-15 - (-25)}{10 - 5}\\\\\frac{10}{5} = 2

Always simplify the fraction!
