The given expression is 
We need to determine the output k, when the input t is -7
<u>Output k:</u>
The value of the output k can be determined by substituting the input 
in the expression
Thus, we have,
Multiplying the terms 10 and -7, we have,
Simplifying, we get,

Answer:
Step-by-step explanation:
Join OB.
∠A=∠A (common)
∴ ΔAPO and ΔAOB are similar.

∠Q=∠B
So PQ║OB
Similarly RS║OB
∴PQ║RS
Answer:
1 3/8
Step-by-step explanation:
First, change the mixed fraction to improper fraction.
2 3/4 = 8/4 + 3/4 = 11/4
1/2 of 11/4 = (11/4)(1/2) = 11/8
11/4 - 11/8 = 22/8 - 11/8 = 11/8
11/8, or 1 3/8 is your answer.
