Help easy math question!!!
bogdanovich [222]

Answer:

The length of the third side of the triangle is 30.

Step-by-step explanation:

Here is the formula for the Pythagorean Theorem:

a^{2} + b^{2} = c^{2}

The hypotenuse, based on the problem, is 50. Anyways, let's get back to calculating!

We need to multiply 40 times 40 and 50 times 50.

40 times 40, or 40 squared, equals to 1600.

50 times 50, or 50 squared, equals to 2500.

c^{2} - b^{2}  = a^{2}

Now, let's subtract. 2500 - 1600 = 900. We need to find the square root of 900--which is 30, because 30 times 30, or 30 squared, equals to 900.

What is the slope of the line (2,3) (1,-2)?
jarptica [38.1K]

Answer: The slope is 5

Step-by-step explanation:

You can calculate the slope of the line with this fomula:

m=\frac{y_2-y_1}{x_2-x_1}

Given the points (2,3) and (1,-2), you can identify that:

y_2=-2\\y_1=3\\x_2=1\\x_1=2

Now, the final step is to substitute these values into the formula  m=\frac{y_2-y_1}{x_2-x_1}, getting that the slope of this line is:

 m=\frac{-2-3}{1-2}

m=\frac{-5}{-1}\\\\m=5
