(q^4)^z=q^12 find the value of z

Daniel [21]

Answer:

z = 3

Step-by-step explanation:

Using the rule of exponents

$(a^{m}) ^{n}$ = $a^{mn}$

Thus

$(q^{4}) ^{z}$ = $q^{4z}$ , so

$q^{4z}$ = $q^{12}$

Since the bases on both sides are equal then equate the exponents

4z = 12 ( divide both sides by 4 )

z = 3

Which two values of x are roots of the polynomial below x^2-11x+17

svetlana [45]

Answer

9.14 and 1.86

Explanation

x²-11x+17

The first thing is to equate it to zero.

x²-11x+17 = 0

x²-11x = -17

x² - 11x + (11/2)² = -17 + (11/2)²

(x² - 11/2)² = -17 + 121/4

(x - 11/2)² = 13.25

x -11/2 = √13.25 or x - 11/2 = -√13.25

x = √13.25 + 11/2 x = -√13.25 + 11/2

= 3.64 + 5.5 = -3.64 + 5.5

= 9.14 = 1.86

Answer:

$f^{-1}(x)=\pm\sqrt{x-10}$

Step-by-step explanation:

You can find the inverse of

y = f(x)

by solving for y:

x = f(y)

x = y² +10

x -10 = y² . . . . . . . . subtract 10

±√(x -10) = y . . . . . take the square root

The inverse relation is ...

$\boxed{f^{-1}(x)=\pm\sqrt{x-10}}$

It is not a function unless some restriction is placed on the domain of f(x).
