Given:
<span>F= $335,000
n = 30 years at a fixed rate of i = 7.5%
Required:
the total cost of the principal
Solution:
F = P(1+i)^n
P = F/(1+i)^n
P = 335,000 / (1.0.075)^30
P = 38,264.05</span>
An equation that models the proportional relationship between t and s.
t = 12.5s
<h3>What is proportional relationship?</h3>
Relationships between two variables where their ratios are equal are known as proportional relationships. The fact that one variable is always a constant value multiplied by the other in a proportionate connection is another way to conceive of them. This parameter is referred to as the "constant of proportionality."
<h3>According to the given information :</h3>
1) Ticket for an art museum costs $12.50
2) In other words, the price will increase by $12.50 for each ticket purchased (or tickets).
In other words, the total expense is always 12.5 times the quantity of tickets sold.
3) This indicates that we can create this ---> t = 12.5s.
An equation that models the proportional relationship between t and s.

X is the domain and y is the range
Answer:
? = 3
Step-by-step explanation:
To find the value of ?, substitute one of the ordered pairs from the table [except (0, 0)] into the given formula and solve for ?.
Given formula:

Substitute x = 1 and y = 3 into the formula:

To isolate ? divide both sides by 1:


Therefore, ? = 3:

Check by inputting another value of x from the table into the found formula and comparing the calculated y-value:


Answer:
-4r
Step-by-step explanation:
r+(-5r)=r-5r=-4r
