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:
∠G ≅ ∠Q
Step-by-step explanation:
<u>Given</u>
<u>Answer choices:</u>
- BI≅PQ - yes correct, corresponding
- ∠B ≅ ∠P - yes correct, corresponding
- ∠G ≅ ∠Q - no, incorrect, it should read ∠G ≅ ∠Z
- ZP ≅ GB - yes correct, corresponding
So, incorrect choice is the third one
Answer:
The exact distance is 
miles.
The distance is approximately 10.4 miles.
Step-by-step explanation:
It is given that a rectangular city is 3 miles long and 10 miles wide. So,
Length = 3 miles
Width = 10 miles
We need to find the distance between opposite corners of the city. It means, we need to find the length of the diagonal of the rectangle.
Using Pythagoras theorem, the length of diagonal is
where, l is length and w is width.
Substitute l=3 and w=10.
The exact distance is miles.
Now,
The distance is approximately 10.4 miles.
