Answer:

triangle given is not a right triangle

Step-by-step explanation:

Given:-

- The side lengths of a triangle are given as:

                                     24 , 32 , 42

Find:-

is it a right triangle? explain

Solution:-

- Any triangle which conforms to the pythagorean theorem can be classified as a right angle triangle.

- The Pythagorean theorem states that the square of the longest side length known as hypotenuse (H) should be equal to the sum of square of other two side lengths ( Perpendicular / opposite [ P ] and Base / Adjacent [ B] ).

- This can be mathematically expressed as:

                                     H^2 = P^2 + B^2

- From the given side lengths. The largest side length is hypotenuse H = 42. While P and B can be used interchangeably for the other two side lengths. So using the theorem we have:

                                     42^2 = 32^2 + 24^2

                                     1764 : 1024 + 576

                                    1764 ≠ 1600

- We see that the three side lengths of the triangle does not conform to theorem. So we can conclude that the triangle given is not a right triangle.

When given 3 triangle sides, to determine if the triangle is acute right or obtuse
square all 3 sides
sum the squares of the 2 shortest sides
compare this sum to the square of the 3rd side
if sum > 3rd side squared it's an acute triangle
if sum = 3rd side squared it's a right triangle
if sum < 3rd side squared it's an obtuse triangle

24 32 42

24*24 = 576
32*32 = 1,024
42*42 = 1,764

Sum of the square of 2 shortest sides = 1,600

Since 1,600 < 1,764 these sides form an obtuse triangle.

Five ninths times the difference of f and 32
Viktor [21]
If we put that into an equation, we get
(5/9)(f/32)
because "five ninths" is a fraction, "times" is multiplication (which can be represented by parenthesis), "the difference" is division, and "the difference of f and 32" is a fraction.

What is the vertex of the quadratic function f(x)=(x-8)(x-2)
Mrac [35]

So firstly, foil (x-8)(x-2): f(x)=x^2-2x-8x+16\\ f(x)=x^2-10x+16

Next, remember that the vertex lies on the axis of symmetry, and the equation to find the axis of symmetry is x=\frac{-b}{2a} (a = x^2 coefficient, b = x coefficient). Solve for the axis of symmetry as such:

x=\frac{10}{2*1}=\frac{10}{2}=5

So now that we know that the axis of symmetry is x = 5, we also know that's the vertex's x-coordinate (since the vertex falls on the axis of symmetry). Now plug in 5 for x in the original equation to solve for f(5):

f(5)=5^2-10(5)+16\\ f(5)=25-50+16\\ f(5)=-9

So putting it together, the vertex of this equation is (5,-9).

A swimming pool holds 600,000 liters of water. The pool has two drainage pipes. When the pool is completely full, the first pipe
Dvinal [7]
<h3>Answer:  1 hour</h3>

==================================

Explanation:

In the method I show below, the value 600,000 liters is never used. All that matters are the two values of 100 minutes and 150 minutes.

Pipe A drains the pool in 100 minutes. The rate it drains the pool is 1/100 of a pool per minute. If you multiply 1/100 by 100, then you'll represent 1 full job being done (that job being draining the pool).

Pipe B drains the pool in 150 minutes. Pipe B's rate is 1/150 of a job per minute.

In total, the combined rate is

1/100 + 1/150 = 3/300 + 2/300 = 5/300 = 1/60 of a pool per minute

This means it takes them 60 minutes to drain the pool assuming the two pipes work the most efficiently together (ie one pipe doesn't hinder the other). Since 60 minutes = 1 hour, it's much easier to say it takes 1 hour to drain the pool with both pipes working together.

---------------------------------

We can get this same answer through solving the equation

1/x + 1/y = 1/z

for z. Use x = 100 and y = 150.
