Midpoint has a formula x plus x2 divided by 2 and vice versa for y
So to solve you need to fill in numbers
You can replace x with negative 2 since you know that the coordinates for point A are -2,4
Solve to get 10
And vice versa for the y coordinate you solve the filled in equation to get 0
Your end result is 10,0
        
             
        
        
        
Answer:
x=4
Step-by-step explanation:
1. distributive property
2. combine like terms
3. inverse operation
4. division or multiplication property
 
        
                    
             
        
        
        
Subtracting -9 from any number is the same as

<u>A</u>
<u>subtracting 9 from that number.</u>
 
        
             
        
        
        
Since ![[0,4]=[0,1]\cup(1,4]](https://tex.z-dn.net/?f=%5B0%2C4%5D%3D%5B0%2C1%5D%5Ccup%281%2C4%5D) , we can rewrite the integral as
, we can rewrite the integral as

Now there is no ambiguity about the definition of f(t), because in each integral we are integrating a single part of its piecewise definition:

Both integrals are quite immediate: you only need to use the power rule

to get
![\displaystyle \int_0^11-3t^2\;dt = \left[t-t^3\right]_0^1,\quad \int_1^4 2t\; dt = \left[t^2\right]_1^4](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Cint_0%5E11-3t%5E2%5C%3Bdt%20%3D%20%5Cleft%5Bt-t%5E3%5Cright%5D_0%5E1%2C%5Cquad%20%5Cint_1%5E4%202t%5C%3B%20dt%20%3D%20%5Cleft%5Bt%5E2%5Cright%5D_1%5E4)
Now we only need to evaluate the antiderivatives:
![\left[t-t^3\right]_0^1 = 1-1^3=0,\quad \left[t^2\right]_1^4 = 4^2-1^2=15](https://tex.z-dn.net/?f=%5Cleft%5Bt-t%5E3%5Cright%5D_0%5E1%20%3D%201-1%5E3%3D0%2C%5Cquad%20%5Cleft%5Bt%5E2%5Cright%5D_1%5E4%20%3D%204%5E2-1%5E2%3D15)
So, the final answer is 15.
 
        
             
        
        
        
Answer: The tailor made 8 complete hats 
Step-by-step explanation:
 Amount of fabrics available to make hat = 6 2/3 yards
1 hat requires = 5/6 yards
 Number of hat to obtain from the available fabric = Amount of fabrics available to make hat / requirement of 1 hat 
=(6 2/3) / (5/6)
(20/3) / (5/6)
20/3 x 6/5 = cancelling out, we are left with 
4x2= 8 hats 
or 
(20/3) / (5/6)
6.6666 /0.83333
= 8.00002= 8 hats
