A drum used for percussion has sides modeled by a hyperbola. The total height of the drum is 35 inches. The diameter at the top of the drum is 16 inches, and the minimum diameter is 8 inches, occurring at a height of 22 inches. Determine the equation of a hyperbola that models the sides of the drum assuming that the center of the hyperbola occurs at the height where the diameter is the least.
look at the screen shot ya know
The equation of a hyperbola that models the sides of the drum assuming that the center of the hyperbola is (35 + a)²/a² - 8²/b² = 1 and (22+ a)²/a² - 4²/b² = 1
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Given that the total height of the drum is 35 inches.
The diameter at the top of the drum = is 16 inches, and
The minimum diameter is 8 inches, occurring at a height of 22 inches.
The equation of the hyperbola be denoted as;
x²/a² - y²/b² = 1
From the question, with x and y coordinates representing height and radius respectively,
Then,
When x = 35 + a, y is = 16/2 = 8 and
At x = 22+ a, y is = 8/2 = 4
Thus,
(35 + a)²/a² - 8²/b² = 1
(22+ a)²/a² - 4²/b² = 1
By solving, we have, a = 128.95 and b = 14.75
Therefore a= 128.95 and b = 14.75

Select one:
∠5°
∠85°
∠95°
∠15°
Answer:
∠95
Step-by-step explanation:
Hello There!
the measure of supplementary angles add up to equal 180
so to find an angle that is supplementary to angle 85 we subtract it from 180
180-85-95
so an angle that is supplementary to angle 85 would have a measure of 95 degrees
wich expression is equivalent to 2,3/5 divided by 7/9
Answer:
117/35 is equalivent expression
Step-by-step explanation:
2 3/5 divided by 7/9
so you need to make 2 3/5 into a fraction
you do the denominator time the whole number plus the numerator to get 13/5
13/5 / 7/9
when you divided fractions you flip the seccond fraction and multiply to get....
13/5 times 9/7

Answer: 20%
Step-by-step explanation: Basically you find the difference which is twelve, and put it over the original amount which is 60. You get 1/5 which in percent form is 20%
The percent of decrease from $60 to $48 is 20%.
What is a percentage?A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.
Let n be the percent of decrease.
60 - 48 = 12
60n = 12
n = 12/60
n = 0.2
n = 20%
