Is a triangle with side lengths 7cm, 24 cm, and 25 cm a right triangle? Explain.

Mathematics

Lina20 [59]3 years ago

Answer:

Step-by-step explanation:

If this is right triangle, then 2 things are fact: that the side length 25 is the length of the hypotenuse since the hypotenuse is always the longest side in a right triangle, and that Pythagorean's Theorem applies. Let's check that:

7^2+24^2=25^2 If this is a true statement, then these sides do indicate a right triangle.

49 + 576 = 625 and

625 = 625 so yes, this is right triangle by the Converse of Pythagorean's Theorem

Identify the graphed linear equation.
Nuetrik [128]

Answer:

The answer to your question is letter C

Step-by-step explanation:

Process

1.- Find two points of the line

   A ( 0, 1)

   B ( 1, -3)

2.- Find the slope of the line

    m = \frac{y2 - y1}{x2 - x1}

    m = \frac{-3 - 1}{1 - 0}

    m = \frac{-4}{1}

           m = -4

3.- Find the equation of the line

            y - y1 = m (x - x1)

            y - 1 = -4( x - 0)

            y -1 = -4x

            y = -4x + 1

1. En una comunidad del Cuzco la Lic. De Salud del Adulto Mayor (60 años a más) reportó los casos de diabetes de los seis primer
VARVARA [1.3K]

Answer:

The problem is about cases of diabetes in old people through months.

The variable is descrete , because it doesn't admit decimal numbers, it represents people, and people are whole numbers.

The frequency table would be

<h3> Months              People</h3>

January                       24

February                     30

March                          20

April                             18

May                             28

June                             12

The total number of people is 132.

The mean would be the total number of people divided by the six months.

\mu = \frac{132}{6} =22

Therefore, the mean is 22 people per month.

Remember that the median is the value at the center of the data set, which is between March and April, so

\frac{20+18}{2}=19

Therefore, the mean is 19.

The third statistical value is determined by the major frequency. So, the data that repeats the most is February, which means that month encloses the majority of people.

If the graph passes the horizontal-line test, then the function is one-to-one. Functions that are one-to-one have inverses that
seropon [69]

Based on the sample response given, the statements included in the explanation on the horizontal line test are:

  • a reference to the horizontal-line test.
  • a statement that the function is one-to-one.
  • inverse is a function.

<h3>What is the horizontal-line test?</h3>

The horizontal line test is used to not only find out if a graph has an inverse function, but also if that inverse is also a function itself.

To pass the horizontal line test, the function has to be one-to-one which means that a horizontal line can intersect the graphed function at one point in all places. If this happens, then there is an inverse and the inverse itself is a function.

Find the volume of this square<br> based pyramid.<br> 5ft<br> 6 ft<br> [? ]ft
Sav [38]

Answer:

48 ft³

Step-by-step explanation:

To find the height, you can use the slant height and the base.

Using the Pythagorean Theorem and 3 as the triangle's base,

a²+b²=c²

3²+b²=5²

9+b²=25

b²=16

b=4

The height of the pyramid is 4.

Volume formula for the pyramid is \frac{1}{3} *b*h

Inserting our measurements:

\frac{1}{3} *6*6*4=\\2*6*4=\\12*4=\\48
