Wesley ran a total of 2 miles.
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:
Answer:
<em><u>38 15/16</u></em>
Step-by-step explanation:
39 + 1/8n
Since the n = -1/2, replace the 'n' in the original equation with that number
39 + 1/8 (-1/2)
Multiply numerator-to-numerator and denominator-to-denominator
1/8 times -1/2 equals -1/16
(Because a positive times a negative equals a negative)
Now your complete equation is:
39 + -1/16
Add those numbers together to get <u>38 15/16</u>
Answer:
Medium
Step-by-step explanation:
The computation is shown below:
The cost for the small and medium bag is shown below:
As we know that
1kg = 1000g
So 3kg = 3000g
Now for small bags
= 0.95 ÷ 250 × 3000
= £11.40
For medium bags
= £1.80 ÷ 500 × 3000
= £10.80
So here the medium bag would represent the better value
Answer:
1/4
Step-by-step explanation:
x^2+x+b= x^2+2*x+1/2+(1/2)^2= (x+1/2)^2
b= 1/4
