Answer:
The price decreased by 16 1/3%, or approximately 16.3%
Step-by-step explanation:
Use the formula for percent change. If the answer is negative, it is a percent decrease. if the answer is positive, it is a percent increase.
percent change = (new price - old price)/(old price) * 100%
In this case, use:
new price = 50
old price = 60
percent change = (new price - old price)/(old price) * 100%
percent change = (50 - 60)/60 * 100%
percent change = -10/60 * 100%
percent change = -1/6 * 100%
percent change = -100/6% = -50/3% = -16 1/3%
The price decreased by 16 1/3%, or approximately 16.3%
The rate of change of the volume with respect to s when s = 15 centimeters is 3375 centimeters
<h3>What is the volume?</h3>
The formula for volume of a cube is given as;
Volume = a³
Where:
a = length of its side
From the information given, we have;
V = s³
Where s = 15 centimeters
Substitute the value into the formula
v = (15)³
v = 3375 centimeters
Thus, the rate of change of the volume with respect to s when s = 15 centimeters is 3375 centimeters

Answer:
45,135,315,225
Step-by-step explanation:
2cos^2x = 1
Divide each side by 2
cos^2x = 1/2
Take the square root of each side
sqrt( cos^2 x) = ±sqrt (1/2)
cos x =±sqrt (1/2)
Make into two separate equations
cos x =sqrt (1/2) cos x = - sqrt(1/2)
Take the inverse cos of each side
cos ^-1 cos (x) = cos ^-1 (sqrt (1/2)) cos ^-1 cos (x) = cos ^-1 (-sqrt (1/2))
x = cos ^-1 (sqrt (1/2)) x = cos ^-1 (-sqrt (1/2))
x = 45 +360 n x = 135+ 360n
x = 315+360 n x =225+360n
Between 0 and 360
