A company promises to release a new smartphone model every month.Each models battery life will be 3% longer than the previous models. If the current models battery life is 684.0 minutes , what will the latest models battery life be 7 months from now ?

Answers

Using an exponential function, it is found that the latest models battery life will be of 841 minutes 7 months from now.

What is an exponential function?

An increasing exponential function is modeled by:

[tex]A(t) = A(0)(1 + r)^t[/tex]

In which:

A(0) is the initial value.r is the decay rate, as a decimal.

In this problem, considering that the current battery life is of 684 minutes, and it should increase by 3% each month, the equation for the battery life after t months is given by:

[tex]A(t) = 684(1.03)^t[/tex]

Then, in 7 months, it will be given by:

[tex]A(7) = 684(1.03)^7 = 841[/tex]

Find the formula for an inverse proportion, knowing that its
graph goes through the point:
C(-25, -0.2)

Answers

The formula for an inverse proportion, knowing that its graph goes through the point: C(-25, -0.2) is y=5/x.

What is inversely proportional relationship?

Let m and n are two variables.

Then m and n are said to be inversely proportional to each other if

[tex]m = \dfrac{c}{n} \\\\ \text{or} \\\\ n = \dfrac{c}{m}[/tex]

(both are equal)

where c is a constant number called constant of proportionality.

This inversely proportional relationship is denoted by

[tex]m \propto \dfrac{1}{n} \\\\ \text{or} \\\\n \propto \dfrac{1}{m}[/tex]

As visible, increasing one variable will decrease the other variable if both are inversely proportional.

The formula for the inverse function is given as,

[tex]y=\dfrac{c}{x}[/tex]

Here, c is constant.

The graph goes through the point: C(-25, -0.2). For the inverse function.

[tex]-25\propto\dfrac{1}{-0.2}\\-25=\dfrac{c}{-0.2}\\c=-25\times-0.2\\c=5[/tex]

Put the value in the above function,

[tex]y=\dfrac{5}{x}[/tex]

This is the required function.

Hence, the formula for an inverse proportion, knowing that its graph goes through the point: C(-25, -0.2) is y=5/x.

Eric and James are looking at this number sequence: 4, 8, 20, 56, 164. What must they do to find the term-to-term rule?

Answers

Answer:

[tex]f(n)=f(n-1) + 4(3)^{n-2}[/tex]

[tex]\textsf{where}\quad f(1)=4[/tex]

Step-by-step explanation:

Given sequence:  4, 8, 20, 56, 164

First, work out the difference in the terms:

[tex]4 \underset{+4}{\longrightarrow} 8 \underset{+12}{\longrightarrow} 20 \underset{+36}{\longrightarrow} 56 \underset{+108}{\longrightarrow} 164[/tex]

As the first differences are not the same, work out the second differences:

[tex]4 \underset{\times 3}{\longrightarrow} 12 \underset{\times 3}{\longrightarrow} 36 \underset{\times 3}{\longrightarrow} 108[/tex]

Therefore, the term-to-term rule is:

[tex]f(n)=f(n-1) + 4(3)^{n-2}[/tex]  

[tex]\textsf{where}\quad f(1)=4[/tex]

[tex]f(2)=f(1) + 4(3)^{2-2}=4+ 4(3)^{0}=4+4=8[/tex]

[tex]f(3)=f(2)+4(3)^{3-2}=8+4(3)^1=8+12=20[/tex]

[tex]f(4)=f(3) + 4(3)^{4-2}=20+4(3)^2=20+36=56[/tex]
