1. What is the constant of proportionality, k,<br><br><br> of Kevin's wage? Greg's? Savannah's?

Gala2k [10]

Answer:

Part a) The constant of proportionality of Kevin's wage is $k=\$8.25\ per\ hour$

Part b) The constant of proportionality of Greg's wage is $k=\$9.00\ per\ hour$

Part c) The constant of proportionality of Savannah's wage is $k=\$9.50\ per\ hour$

Step-by-step explanation:

See the attached figure to better understand the problem

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form $y/x=k$ or $y=kx$

To find out the constant of proportionality k , divide the variable y (total earned) by the variable x (number of hours)

<em>Kevin's wage</em>

Take any point from the table

I take the point (2,16.50)

$k=\frac{16.50}{2}=\$8.25\ per\ hour$

<em>Greg's wage</em>

Take any point from the table

I take the point (3,27.00)

$k=\frac{27.00}{3}=\$9.00\ per\ hour$

<em>Savannah's wage</em>

Take any point from the table

I take the point (2,19.00)

$k=\frac{19.00}{2}=\$9.50\ per\ hour$

If an object is dropped from a height of 116 feet, the function h(t)=-16t^2+116 gives the height after t seconds. When will the

7nadin3 [17]

Let h(t)= 0 (because when it reaches the ground h=0)

0=-16t^2+116
16t^2=116
divide both sides by 16
t^2= 7.25
square root both sides to find t
t=2.69sec

Which represents the empirical formula for A3B9?<br> AB3<br> AB2<br> A3B9<br> A9B27

DaniilM [7]

Answer:

$AB_{3}$

Step-by-step explanation:

Given : $A_{3}B_{9}$

To Find : Which represents the empirical formula for $A_{3}B_{9}$ ?

Solution:

Definition of Empirical Formula - A formula that gives the simplest whole-number ratio of atoms in a compound.

$A_{3}B_{9}$

To reduce it in simplest form

Divide the subscript numbers by 3

So, the resultant : $AB_{3}$

Thus the empirical formula for $A_{3}B_{9}$ :

$AB_{3}$
