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 $c=\sqrt{20} =4.5$ .

Which function represents a horizontal shift of ƒ(x) = 5(2)^3x by 4 units to the right?

Dmitry_Shevchenko [17]

General Idea:

Say if f(x) is the parent function, then f(x-c) represents transformation described as horizontal translation or shift of f(x) by ' c ' units to the right.

Applying the concept:

Here we are given a function $f(x)=5(2)^{3x}$ , after the transformation of horizontal shift of 4 units to the right, the function will be given as below:

$f(x)=5(2)^{3(x-4)}=5(2^{3})^{x-4}=5(8)^{x-4} \\ or\\ f(x)=5(2)^{3x-12}$
