So to begin, substitute all of the variables in for their corresponding value.
X=3
Y=-5
Z=-1
2XY+6YZ^2
2(3)(-5)+6(-5)(-1^2)
-30+-30
-60
Hopefully this is what they're asking for!
The answer is 16
And also , can people please stop posting did you get the answer yet, just so you could get the points. They only take two answers, and that's a waste of somebody who could've answered or helped.
Answer:
x = 5.333 , y= 9.620764575
Step-by-step explanation:
sin(29)/x = sin(90)/11
x = 11* sin(29)/sin(90)
x = 5.333
(5.333)^2 + y^2 = 121
y^2 = 121 - (5.333)^2
y= 9.620764575
4 is the correct answer or x=4 ✌️
Answer:
9t + 4c ≤ 250
3t + 2c ≤ 80
Step-by-step explanation:
t is the number of tables
c is the number of chairs
Each table takes 9 hours to assemble and 3 hours to finish, so t tables take 9t hours to assemble and 3t hours to finish.
Each chair takes 4 hours to assemble and 2 hours to finish, so c chairs take 4c hours to assemble and 2c hours to finish.
Therefore, total assembly time is 9t + 4c. Total finishing time is 3t + 2c.
Total assembly time is at most 250, and total finishing time is at most 80.
9t + 4c ≤ 250
3t + 2c ≤ 80
