Answer:
23.63
Step-by-step explanation:
3.4 x 6.95
Answer:
452.39
Step-by-step explanation:
The question is asking for the area of the pool, so use the circle area formula, which is A=
. In the formula, A is the area and r is the radius. The question gives us the diameter, so divide that by 2 to get the radius. Therefore the equation is A=
, then solve to get 452.39.
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)
Step-by-step explanation:
5-(-4)
5 + 4 = 9
exceeds by 9
Answer:
k > 7
Step-by-step explanation:
Given the inequality statement: 4k - (5 + 3k) > 2
Distribute -1 into (5 + 3k):
4k -5 - 3k > 2
Next, add like terms:
k - 5 > 2
Add 5 to both sides of the inequality:
k - 5 + 5 > 2 + 5
k > 7
