Answer:
Where's the graph?
Step-by-step explanation:
Given cost function C(a) = 7.5a, where a is the number of T-shirts.
Let us complete table.
We need to plug a=1,2,3,4 in above function to get the costs to complete the table.
For a =1
C(1)= 7.5(1) = 7.50
For a =2
C(2)= 7.5(2) = 15.00
For a =3
C(3)= 7.5(3) = 22.50
For a = 4
C(4)= 7.5(1) = 30.00
In order to find the common difference we need to find the diffrences of costs 15-7.50 = 7.50
22.50-15.00=7.50.
<h3>Therefore, common difference is 7.5.</h3>
a represents the number of T-shirts.
Domain of a is the numbers we can take for a.
So, we can take value for a as 0 or greater value.
Therefore, domain for a would be a is gerater than or equal to 0.
<h3>Domain : a≥0</h3>
Answer: a. Kurtis is moving to a new city to start the job he was hired for.
Step-by-step explanation: <em>"is moving"</em> is present progressive tense.
<em>"was hired" </em>is passive past tense.
<em>"to start" </em>is an infinitive.
These are correct verb forms.
b is almost correct. Kurtis "moved" is OK in the past tense. *is started* should be "has started"
c is partly correct. *to starting* is ungrammatical here.
d is wrong because *to started* is always ungrammatical.
Answer:
12.50 ft per hour
Step-by-step explanation:
Given that:
Fish pond has a rectangular shape.
Length of fish pond = 60 feet
Width of fish pond = 40 feet
Total time to complete the fencing = 16 hours
To find:
Unit rate of putting the fencing around the fish pond.
Solution:
First of all, we need to find the total fencing to be put around the fish pond.
Total fencing is nothing but the perimeter of the fish pond which is of rectangular shape.
Formula for perimeter of rectangular shape is given as:


Unit rate is the perimeter divided by total time taken to put the fencing around.
Therefore,
Unit rate =
feet per hour
So, the answer is <em>12.5 feet per hour</em>.
