Find the length of the third side. If necessary, round to the nearest tenth.
schepotkina [342]

Answer:

4.5

Step-by-step explanation:

To find the hypotenuse of a right triangle, we use Pythagorean's Theorem which states that a^{2}+b^{2} =c^{2}. Plugging in the values of the two legs given, we get 2^{2} +4^{2} =c^{2} =20. We can take the square root of each side and get that c=\sqrt{20} =4.5.

You need to find the x and y intercepts so...

The x intercept is (18,0) since x=18

Find the 10th term of the geometric sequence 1, 3, 9, .
spin [16.1K]

Answer:

19683

Step-by-step explanation:

As the formula of the geometric sequence:

a_{n} =a_{1} *r^{n-1}

In the sequence of 1, 3, 9..., you have a1 = 1 and r = 3. Therefore:

a_{10} =1 *3^{10-1}  = 3^{9} =19683

Hope this helps!
