Charlie reads quickly. He reads 1\dfrac371 7 3 1, start fraction, 3, divided by, 7, end fraction pages every \dfrac23 3 2 st

OLEGan [10]

<h2>Answer:</h2>

The number of pages he will read in one minute is:

$2\dfrac{1}{7}\ \text{pages}$

<h2>Step-by-step explanation:</h2>

It is given that:

Charlie reads $1\dfrac{3}{7}\ \text{pages}$ in every $\dfrac{2}{3}\ \text{minutes}$ .

We know that:

$1\dfrac{3}{7}=\dfrac{10}{7}$

This means that:

Charlie reads $\dfrac{10}{7}\ \text{pages}$ in every $\dfrac{2}{3}\ \text{minutes}$ .

This means that:

$\text{In}\ \dfrac{2}{3}\ \text{minutes he reads}\ \dfrac{10}{7}\ \text{pages}\\\\\text{Hence}$

$\text{In}\ 1\ \text{minute he will read}\ \dfrac{\dfrac{10}{7}}{\dfrac{2}{3}}\ \text{pages}$

$\text{In}\ 1\ \text{minute he will read}\ \dfrac{10\times 3}{7\times 2}\ \text{pages}$

Hence,

$\text{In}\ 1\ \text{minute he will read}\ \dfrac{15}{7}\ \text{pages}$

Hence,

$\text{In}\ 1\ \text{minute he will read}\ \dfrac{15}{7}\ \text{pages}$

$\text{In}\ 1\ \text{minute he will read}\ 2\dfrac{1}{7}\ \text{pages}$

I need help...... Write the domain and range of each of the functions graphed below. 1. Domain: ___________________ Range: _____

Mamont248 [21]

Answer:

Step-by-step explanation:

Domain of any function is represented by the x-values and Range is represented by the y-values.

Graph (1),(Row (1) first graph)

Domain → (-∞, ∞) Or set of all real numbers

Range → (-∞, ∞) Or set of all real numbers

Graph (2) (Row (1) second graph)

Domain → [0, ∞} Or x ≥ 0

Range → [-2, ∞) Or x ≥ -2

Graph (3) [Row (2) first graph]

Domain → (-∞, ∞) Or set of all real numbers

Range → (-∞, ∞) Or set of all real numbers

Graph (4) [Row (2) second graph]

Domain → (-∞, ∞) Or set of all real numbers

Range → [4, ∞) Or x ≥ 4

1.5, 2.25, 3.0, 3.75, ...

The recursive formula can be used to determine the total amount of time spent making hats based on the total amount of time spent previously is f(n + 1) = f(n) + 0.75

<h3>Recursive functions</h3>

The general recursive function is expressed as:

an+1 = d + an

where

r is the common difference

Given the sequence below

1.5, 2.25, 3.0, 3.75, ...

Common difference = 2.25 - 1.5 = 0.75

Substitute

f(n + 1) = f(n) + d

f(n + 1) = f(n) + 0.75

Hence the recursive formula can be used to determine the total amount of time spent making hats based on the total amount of time spent previously is f(n + 1) = f(n) + 0.75
