Hello!
To be perpendicular to x = 4, the line must be y = something. This eliminates answer choices #2 and #4. Also, to pass through the point (.5, 7), the line must be y = 7.
So answer choice #3.
Hope this helps!! Let me know if you have ANY questions.
Given :
- Area of square equals to the area of rectangle of sides 4.9m and 1.6m .
To find :-
Solution :-
<u>As </u><u>we</u><u> know</u><u> </u><u>,</u>
- Area = side²
- 4.9 * 1.6 = a²
- a = √ 49/10 * 16/10
- a = 7/10 * 4/10
- a = 28/100
- a = 0.28 m
When an interval says (0, 2pi). This means all angles ranging from 0 to 2pi with 0 and 2pi not included in the values. The parenthesis means the values in the right or left of it is not included while a bracket is used to indicate the values used as limits are included

Answer:
1. Discrete-time signals are represented mathematically as sequences of numbers. A sequence of numbers x, in which the nth number in the sequence is denoted x[n],
1 is
formally written as
x = {x[n]}, −∞ <n< ∞, (2.1)
2. where n is an integer. In a practical setting, such sequences can often arise from periodic
sampling of an analog (i.e., continuous-time) signal xa(t). In that case, the numeric value
of the nth number in the sequence is equal to the value of the analog signal, xa(t), at
time nT : i.e.,
x[n] = xa(nT ), −∞ <n< ∞. (2.2)
