3x ² - 2x + 1 = 2x ² - 3x + 7

x ² + x - 6 = 0

(x + 3) (x - 2) = 0

x + 3 = 0 or x - 2 = 0

x = -3 or x = 2

Given an exponential function for compounding interest, A(x) = P(.95)x, what is the rate of change?

statuscvo [17]

Answer:

Option 3

The rate of change is -5%

Step-by-step explanation:

Given : An exponential function for compounding interest, $A(x) = P(.95)^x$

To find : What is the rate of change?

Solution :

The general form of an exponential function is:

$f(x) = a(1+r)^x$

Where, a is the initial amount,

(1+r) is the rate of change,

r is the growth or decay factor

We have given, $A(x) = P(.95)^x$

Rate of change is

$1+r=0.95$

$r=0.95-1$

$r=-0.05$

Convert to percent,

$r=-0.05\times 100=-5\%$

Therefore, Option 3 is correct.

What is the common ratio of the geometric sequence; *

Tanya [424]

Answer:

Step-by-step explanation:

The common ratio r of a geometric sequence is

r = $\frac{a_{2} }{a_{1} }$ = $\frac{\frac{10}{3} }{10}$ = $\frac{10}{3}$ × $\frac{1}{10}$ = $\frac{1}{3}$ → C
