Answer:
Tamara's example is in fact an example that represents a linear functional relationship.
- This is because the cost of baby-sitting is linearly related to the amount of hours the nany spend with the child: the more hours the nany spends with the child, the higher the cost of baby-sitting, and this relation is constant: for every extra hour the cost increases at a constant rate of $6.5.
- If we want to represent the total cost of baby-sitting in a graph, taking the variable "y" as the total cost of baby-sitting and the variable "x" as the amount of hours the nany remains with the baby, y=5+6.5x (see the graph attached).
- The relation is linear because the cost increases proportionally with the amount of hours ($6.5 per hour).
- See table attached, were you can see the increses in total cost of baby sitting (y) when the amount of hours (x) increases.
Answer:
The unit rate is $8.89 /ft².
Step-by-step explanation:
Given:
$160 for 18ft².
So, by dividing with 18
we get
.
Now, round to nearest hundredth for $8.888 is $8.89.
Therefore, the unit rate is $8.89 /ft².
Answer:
suppose that r = 50%=0.5,
t =10 years and P= 100, find A?
A=100(1+(0.5)(10))=600
suppose t =10 yrs, r=50%, A=600, find P?
P=600/((1+(0.5)(10))=100
suppose t =10 yrs, r=50%, A=600, P= 100 find r?
r= (600-100)/100(10)=500/1000=0.5=50%
suppose r=50%, A=600, P= 100 find t?
t= (600-100)/100(0.5)=500/50=10 yrs
