FrozenT [24]

Answer:

$f(x) = 4 \times (\dfrac{1}{8})^{x}$ .

Step-by-step explanation:

Let $f(x) = a \cdot b^{x}$ represent this exponential function. $a \ne 0$ , $b > 0$ .

$b^{0} = 1$ . As a result, $a = f(0) = 4$ .

$a \cdot b = 4 \cdot b = f(1) = \dfrac{1}{2}$ .

As a result,

$b = \dfrac{1}{8}$ .

$f(x) = a \cdot b^{x} = 4 \times (\dfrac{1}{8})^{x}$ .

This function represents an exponential decay since $0 < b < 1$ .

Need answer solve for w w + 7.1 ———- = 2.87 3

Scorpion4ik [409]

Answer: 1.51

Step-by-step explanation:

$\frac{w + 7.1}{3} =2.87$

$3(\frac{w+7.1}{3})=3(2.87)$

w + 7.1 = 8.61

w + 7.1 - 7.1 = 8.61 - 7.1

w = 1.51

3600 dollars is placed in an account with an annual interest rate of 5.5%. To the nearest year, how long will it take for the ac

Lynna [10]

Answer:

14.44

Step-by-step explanation:

The formula says

A=p(1+r)^t

A 7800

P 3600

R 0.055

T ?

7800=3600(1+0.055)^t

7800/3600=(1.055)^t

Log(7800/3600)= t × log(1.055)

T=log(7800/3600)/log(1.055)

T= 14.44 years
