Answer:
$42.49
Step-by-step explanation:
s=p−(p×d)
Where:
s
is the sales price: what we are solving for in this problem
p
is the original price: $49.99 for this problem
d
is the discount percent: 15% for this problem. "Percent" or "%" means "out of 100" or "per 100", Therefore 15% can be written as
15/100. Substituting and calculating
s gives: s =$49.99-($49.99×1510)
s=$49.99−$749.8100
s=$49.99−$7.4985 s=$42.4915 s=$42.49
rounded to the nearest cent.
The sales price of the video game is $42.49
Answer:

Step-by-step explanation:
The equation of a periodic function is in the form:
y = Asin(Bx + C) + D
Where A = amplitude, B = 2π / period, D = vertical shift, phase shift = -C / B.
Given that:
amplitude: 4, period 4 phase shift = vertical shift = -2
Hence:
A = amplitude = 4, B = 2π / period = 2π / 4 = π / 2, D = vertical shift = -2.
Phase shift = -C / B
C = -phase shift * B = - * -2 * π / 2 = π.
Therefore substituting gives:

Answer:
x=3
Step-by-step explanation:
