The solution is option D.
0 4
- 6 1
3 -4
Rember rows times columns.
=>
a11 = 4*0 + 0*(-3) = 0
a12 = 4*1 + 0*1 = 4 + 0 = 4
a21 = -1*0 + 2*(-3) = 0 - 6 = -6
a22 = -1*1 + 2*1 = -1 + 2 = 1
a31 = -3*0 + (-1)*(-3) = 0 + 3 = 3
a32 = -3*1 + (-1)*1 = -3 - 1 = -4
Answer: ![\large \boldsymbol{\dfrac{1}{8 } (x^2-3)^4+c}](https://tex.z-dn.net/?f=%5Clarge%20%5Cboldsymbol%7B%5Cdfrac%7B1%7D%7B8%20%7D%20%28x%5E2-3%29%5E4%2Bc%7D)
Step-by-step explanation:
![\displaystyle \large \boldsymbol{} \int\limits {x(x^2-3)^2 } \, dx =\int\limits \frac{1}{2} {} \, (x^2-3)' (x^2-3)^3 dx =\frac{1}{8} (x^2-3)^4+c](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Clarge%20%5Cboldsymbol%7B%7D%20%20%5Cint%5Climits%20%7Bx%28x%5E2-3%29%5E2%20%7D%20%5C%2C%20dx%20%3D%5Cint%5Climits%20%5Cfrac%7B1%7D%7B2%7D%20%20%7B%7D%20%5C%2C%20%28x%5E2-3%29%27%20%28x%5E2-3%29%5E3%20dx%20%20%3D%5Cfrac%7B1%7D%7B8%7D%20%20%28x%5E2-3%29%5E4%2Bc)
It took her 1 hour to get to the appointment; at 80mph that means the appointment was 80 miles away.
I believe she will have 25 quarters.
Step-by-step explanation:
Create a proportion.
![\frac{4}{2.60} =\frac{7}{x}](https://tex.z-dn.net/?f=%20%5Cfrac%7B4%7D%7B2.60%7D%20%3D%5Cfrac%7B7%7D%7Bx%7D%20%20)
Cross multiply.
4x = 18.2
Divide both sides by 4.
x = 4.55
It will cost $4.55 to purchase 7 croissants.
