For which function does f decrease by 15% every time x increases by 1

LenaWriter [7]

Answer:

$f(x) = 0.85^{x}$

Step-by-step explanation:

The exponential function that decrease by 15% every time x increases by 1 is given by:

$f(x) = {(1 - 0.15)}^{x}$

We simplify the parenthesis to get:

$f(x) = 0.85^{x}$

Therefore the decrease by 15% every time x increases by 1 is

$f(x) = {0.85}^{x}$

The second choice is correct.

In circle O, AP = √10, PB = x and BC = 3. Find the value of x.

Artyom0805 [142]

Answer:

The value of x is $2\ units$

Step-by-step explanation:

we know that

Applying the tangent-secant theorem

$AP^{2}=PB*PC$

substitute the values and solve for x

$\sqrt{10}^{2}=x*(x+3)$

$10=x^{2}+3x$

$x^{2}+3x-10=0$

using a graphing tool

to solve the quadratic equation

The solution is $x=2\ units$
