Answer:
$ 3,213.30
Step-by-step explanation:
2350(1.09)¹⁰ - 2350 = 3,213.30
The first column is x while the second is y. To find rate, you divide y by x. If each row has the same outcome, it is proportional.
First row:
9.00÷2= 4.50
Second row:
22.50÷5= 4.50
Third row:
31.50÷7= 4.50
There is a proportional relationship based off of the values.
So B, yes there is a constant of proportionality of $4.50.
Answer:
(b)
P = [4(4a + 3b]/(2a + b)
Step-by-step explanation:
P = 2L + 2W
P = [2(5a + 4b) + 2(3a + 2b)]/(2a + b)
P = [10a + 8b + 6a + 4b]/(2a + b)
P = [16a + 12b]/(2a + b)
P = [4(4a + 3b]/(2a + b)
Answer:
-33
Step-by-step explanation:
The rational number -33 is equal to -33
Answer:

Step-by-step explanation:
From the question we are told that
The vector given is

Also 
Generally

Here
is the magnitude of a which is mathematically represented as

=> 
b is vector which we will assume to have the following parameters

So

=> 
=> 
Hence the vector be can be mathematically represented as

This means that the vector b is more than one value since it is made up of variable
This means that if

Then
