2 onea and 8 tens is a way to express it
Answer:
when a expression is squared (²) that means it is multiplyed by itself.
Step-by-step explanation:
(1/2)² = (1/2 x 1/2)
1 squared = 1
2 squared = 4
1/4 is smaller than 1/2. 1/2 is greater than (1/2)²
Answer:
Step-by-step explanation:
The interval [4, ∞) all real numbers 4 and greater, whereas the interval (4,∞) not includes the endpoint 4.
Answer: The value of y is 39.6 when x = 11 and the required expression is y(11) = 39.6
Step-by-step explanation:
Since we have given that
y varies directly as x.
If y = 18, when x = 5.
So, we need to find the value of y when x is 11.
According to question, we get that

Hence, the value of y is 39.6 when x = 11 and the required expression is y(11) = 39.6
