Which is the graph of f(x) =4(1/2)^x

Mathematics
1 answer:
Nuetrik [128]4 years ago
6 0

Answer:

The graph in the attached figure

Step-by-step explanation:

we have

f(x)=4(\frac{1}{2})^{x}

This is a exponential function of the form

y=a(b)^{x}

where

a is the initial value

b is the base

r is the rate

b=1+r

In this problem we have

a=4 ----> initial value (y-intercept)

b=1/2

so

1+r=1/2

r=1/2-1=-1/2

r=-0.5=-50% ----> is negative because is a decrease rate

using a graphing tool

The graph in the attached figure

<em>Note: I am assuming we have to determine the angle 'Ф'.</em>

Answer:

The value of Ф = 22.6°

Step-by-step explanation:

Given

hypotenuse = 13

To determine:

Angle = Ф = ?

Using the trigonometric ratio

cos Ф = adjacent / hypotenuse

here

  • hypotenuse = 13
  • Adjacent to Ф = 12

so substituting adjacent = 12, hypotenuse = 13 in the equation

cos Ф = adjacent / hypotenuse

cos Ф = 12 / 13

Ф = arccos (12/13)

Ф = 22.6°

Therefore, the value of Ф = 22.6°

Find the slope of the line on the graph. Write yoyur answer as a frction or a whole number, not a mixed number or decimal.
BigorU [14]
Okay, so I'm almost positive the slope is m=1/1. I know this because the line rises one and runs one.
