Use a calculator to evaluate cot 3.14/5

Mathematics

Sonja [21]4 years ago

You need to be a little careful here. cot(3.14/5) ≠ cot(π/5) to the accuracy shown. 3.14 is not a useful approximation for π if you want to use more than 3 significant digits in your result.

The 2nd selection is appropriate. (1.376)

Write an equation of a piecewise defined function with the given conditions: domain is (-3, 2) u (2, ∞) range is (-1, ∞) functio
Korvikt [17]
\left \{ {{f(x)=x+2, -3\ \textless \ x\ \textless \ 2} \atop {f(x)=x-2, 2\ \textless \ x\ \textless \ infinity}} \right.

f(x) has to be close to -1 when x is close to -3, and so f(x) is increasing when x increases, and there are no numbers from -1 to ∞ that there is no f(x) value. In the first piece of the function <span>f(x) ranges from -1 to 4 and the second piece from 0 to ∞ so. The ranges had to overlap since it's not defined at x = 2.</span>

A triangle has sides of lengths 8,15 and 17. is it a right triangle? explain
babunello [35]

Answer:

Yes, a triangle with sides 8,15 and 17 is a right triangle.

Step-by-step explanation:

The Pythagorean theorem solely applies to right triangles, and if the sum of the square of the two sides of a triangle equal the square of the hypotenuse, then you have a right triangle.

To set it up, remember that the side opposite 30 degrees will be the smallest of the three numbers, and the side opposite 90 degrees (the hypotenuse) will be the largest, leaving the middle number as opposite 60 degrees. If you solve 8^2 + 15^2, you get 289, which is equal to 17^2.
