Answer: D
<u>Step-by-step explanation:</u>
In order to increase each ticket by $2, you are ADDING 2 to each value.
So you create a matrix of all 2's and add that to the given matrix.
![\left[\begin{array}{cc}2&2\\2&2\\2&2\end{array}\right] +\left[\begin{array}{cc}8&10\\12&16\\6&8\end{array}\right]\quad =\quad \large \left[\begin{array}{cc}10&12\\14&18\\8&10\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D2%262%5C%5C2%262%5C%5C2%262%5Cend%7Barray%7D%5Cright%5D%20%2B%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D8%2610%5C%5C12%2616%5C%5C6%268%5Cend%7Barray%7D%5Cright%5D%5Cquad%20%3D%5Cquad%20%5Clarge%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D10%2612%5C%5C14%2618%5C%5C8%2610%5Cend%7Barray%7D%5Cright%5D)
Answer:
1=51°
2=18°
3=123°
4=39°
Step-by-step explanation:
Use this rule: <em>(x^a)^b = x^ab</em>
3(x + 2)^3/5 + 2 = 27
Subtract 3 from both sides
3(x + 2)^3/5 = 27 - 3
Simplify 27 - 3 to 24
3(x + 2)^3/5 = 24
Divide both sides by 3
(x + 2)^3/5 = 24/3
Simplify 24/3 to 8
(x + 2)^3/5 = 8
Take the cube root of both sides
x + 2 = 3/5√8
Invert and multiply
x + 2 = 8^5/3
Calculate
x + 2 = 2^5
Simplify 2^5 to 32
x + 2 = 32
Subtract 2 from both sides
x = 32 - 2
Simplify 32 - 3 to 30
<u>x = 30</u>
Answer:
x0.046*3=15000
x0.045=5000
x=111111.111111
so you have to deposit 111111.12 every month
