Step-by-step explanation:
3×3+8
i applied BODMASS RULE
1) F + (N - 1)*D=Nth Term, where F=First term, D=Common difference and N=Number of terms.
-1 + (8 - 1)*D =20, solve for D
-1 + 7D = 20
7D = 20 + 1
7D =21 divide both sides by 7
D = 21 / 7
D = 3 Common difference
2)
(F + L) / 2*N, where F=First term, L=Last term and N=Number of terms.
Sum = (-7 - 115) / 2*13
Sum =( -122 / 2) * 13
Sum = -61 * 13
Sum = -793
Answer:
The inequality representing the time taken by the entire cycle is:
Step-by-step explanation:
The time taken to complete one cycle of a manufacturing machine is no longer than 3 minutes.
It is provided that the manufacturing machine has two processes.
One of them is repeated 4 times and the second only once.
Assume that the variable <em>x</em> represents the time taken to complete the first process once.
Then the time taken to complete the first process 4 times would be, 4<em>x</em>.
Also assume that the variable <em>y</em> represents the time taken to complete the second process.
Then the inequality representing the time taken by the entire cycle is:
Consider the graph below representing the above equation.
