Answer:
The value of z is:
z = 6
Step-by-step explanation:
We have been given 4 options of z. Lets substitute each value in the given equation to see which option satisfies.
<h3 /><h3>For z = 3</h3>
sin(9z - 1) = cos(6z + 1)
sin(9(3) - 1) = cos(6(3) + 1)
sin(26) = cos(19)
0.438 = 0.945
FALSE
<h3 /><h3>For z = 4</h3>
sin(9z - 1) = cos(6z + 1)
sin(9(4) - 1) = cos(6(4) + 1)
sin(35) = cos(25)
0.574 = 0.965
FALSE
<h3 /><h3>For z = 5</h3>
sin(9z - 1) = cos(6z + 1)
sin(9(5) - 1) = cos(6(5) + 1)
sin(44) = cos(31)
0.695 = 0.857
FALSE
<h3 /><h3>For z = 6</h3>
sin(9z - 1) = cos(6z + 1)
sin(9(6) - 1) = cos(6(6) + 1)
sin(53) = cos(37)
0.799 = 0.799
TRUE
<h3 />
The first one is the correct answer.
When you multiply, you end up with 49x^16+28xy^40-28x^40 -16y^64
The two middle terms cancel out so you end up with 49x^16-16^64.

Step-by-step explanation:
Well, I'm not sure if I'm correct, but from what I've learned, and independent variable is first which could be the temperature.
Answer:
![\huge\boxed{\sf 25\ ml}](https://tex.z-dn.net/?f=%5Chuge%5Cboxed%7B%5Csf%2025%5C%20ml%7D)
Step-by-step explanation:
Total amount of water = 500 ml
Mary drank = 400 ml
<u>Left:</u>
= 500 ml - 400 ml
= 100 ml
This was divided equally among 4 friends.
So,
<u>Each friend got:</u>
= 100 ml/4
= 25 ml
