$f(x) = {x}^{2} + 5$

$y = {x}^{2} + 5$

${x}^{2} + 5 = y$

Subtract sides 5

${x}^{2} + 5 - 5 = y - 5$

${x}^{2} = y - 5$

$x = ± \sqrt{y - 5}$

$x≠ - \sqrt{y - 5}$

Because x is a positive number but -√y-5 is a negative number thus it's unacceptable.

So ;

$x = \sqrt{y - 5}$

_________________________________

${f}^{ - 1}(x) = \sqrt{x - 5}$

Done...

There are some caps in a box. 1/6 of them are red, 1/3 are blue, and 3/7 of the remainder are green. If there are 27 green caps,

3241004551 [841]

$\frac{1}{6}x+\frac{1}{3}x+\frac{3}{7}(x-(\frac{1}{6}x+\frac{1}{3}x))=x\\\frac{3}{7}(x-(\frac{1}{6}x+\frac{1}{3}x))=27\\\frac{3}{7}(x-(\frac{1}{2}x))=27\\\frac{3}{7}(\frac{1}{2}x)=27\\x=126$

126 caps

Given that cosA = -8/17 and sinA is negative, determine the value of tanA.

borishaifa [10]

Answer:

tan A = -15/8.

Step-by-step explanation:

sin^2a = 1 - cos^2A

= 1 - (-8/17)^2

= 225/289

So sin A= 15/17

tan A = sin A / cos A

= 15/17 / -8/17

= 15/-8

= -15/8.
