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:
4
Step-by-step explanation:
Answer:
g(-1)=4 ,f(g(-1))=18
Step-by-step explanation:
g(-1):
1-3(-1)=4
f(g(-1)):
sub in g(-1) as x
(4)^2+2=18
Y=mx+b is the slope-intercept equation where m is the slope of a line and b is the y value of an x intercept. to solve for slope we have (y1-y2)/(x1-x2) where y1 and y2 are y values of 2 points, and x1 and x2 the x values of those points. so we have (0,5) and (3,4). These can be plugged in to get (5-4)/(0-3) or -1/3. then this is plugged in along with 5 for the x intercept to get y=-1/3*x+5 as the answer for 6. Completing the same process for the slope of #7 we can get (-12-(-2))/(0-8) or -10/-8 or 5/4. Again we plug in to get y=5/4*x-12 as the answer for 7.
