Answer:
[tex]f^{-1} (x) = \sqrt[3]{\frac{1 - 9x^{2} }{x^{2} } }[/tex]
Step-by-step explanation:
Let f(x) = y
Interchange x and y so
[tex]x = \frac{1}{\sqrt{y^{3} + 9 } }[/tex]
[tex]x\sqrt{y^{3} + 9} = 1[/tex]
[tex]\sqrt{y^{3} + 9 } = \frac{1}{x}[/tex]
[tex]y^{3} + 9 = \frac{1}{x^{2} }[/tex]
[tex]y^{3} = \frac{1}{x^{2} } - 9[/tex] = [tex]\frac{1 - 9x^{2} }{x^{2} }[/tex]
[tex]y = \sqrt[3]{\frac{1 - 9x^{2} }{x^{2} } }[/tex]
[tex]f^{-1} (x) = \sqrt[3]{\frac{1 - 9x^{2} }{x^{2} } }[/tex]

In ΔFGH, the measure of ∠H=90°, HG = 56, FH = 33, and GF = 65. What ratio represents the cosine of ∠G? ASAP PLS
Answers
The value of ratio which represents the cosine of ∠G is,
⇒ cos G = 56/65
What is mean by Triangle?A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
We have to given that;
In ΔFGH,
The measure of ∠H=90°, HG = 56, FH = 33, and GF = 65.
Now, By the formula;
⇒ cos θ = Base / Hypotenuse
Hence, We get;
⇒ cos G = GH / GF
⇒ cos G = 56/65
Thus, The value of ratio which represents the cosine of ∠G is,
⇒ cos G = 56/65

Q2. In a camp food was enough for 400 people for 23 days. If 60 more people joined the camp, find the number of days the food will last?
Q3. Given that y is directly proportional to x and that y= 40 when x= 200, find the value of
(a) y when x= 15
(b) x when y= 8
Q4. If y is inversely proportional to x and that y= 8 when x= 30, find the value of:
(a) the value of y when x= 4
(b) the value of x when y= 360
Answers
Answer:
Q2)
We have food for 400 people, and it will last for 23 days.
Then we have an inverse relation, where the number of days decreases as the number of people increases, this means that we have a relationship like:
23 days = K/400 people.
Then we get:
(23 days)*(400 people) = K = 9200 days*people.
Now if we increase the number of people by 60, we get.
people = 460
Then the number of days that this will last is:
D = (9200 days*people)/460 people = 20 days.
The food will last for 20 days.
Q3) We have a proportional relationship (y = k*x) such that y = 40 when x = 200, then we get:
40 = k*200
With this, we can find the value of k
40/200 = k = 0.2
Then the proportional relationship is:
y = 0.2*x
a) We need to replace x by 15.
y = 0.2*15 = 3
y = 3
b) We need to replace y by 8.
8 = 0.2*x
8/0.2 = x = 40
x = 40
Q3) y is inversely proportional to x (y = k/x), and y = 8 when x = 30.
Then we get:
8 = k/30
Then the value of k is:
8*30 = k = 240
then the relationship is:
y = 240/x
a) we need to replace x by 4
y = 240/4 = 60
y = 60
b) we need to replace y by 360
360 = 240/x
360*x = 240
x = 240/360 = 0.666...
x = 0.666...

Over a 24 hour period the temperature in a town can be modeled by one period of a sinusoidal function. The temperature measures 70*F in the morning, rises to a high of 80*F, falls to a low of 60*F, and then rises to 70*F by the next morning.
What is the equation for the sine function f(x), where x represents time on hours since the beginning of the 24 hour period that models the situation
Answers
Start with an initial temperature of T0 = 70° at t = 0 hours, and add to that a sine function that does the following, in order:
Rises by 10°, reaching 80° after 6 hours
Drops by 10º, reaching 70° after 12 hours
Drops by 10°, reaching 60° after 18 hours
Rises by 10°, reaching 70° after 24 hours
Note that the amplitude of the sine function is A = 10°.
T = period of the sine function
T = 24 hours
f(x) = T0 + A sin[(2π/T)x]
where
T0 = 70°
A = 10°
T = 24 hours
x = elapsed time in hours
f(x) = 70º + (10°)sin[(π/12)x]
with x in hours.
Test this solution and see that it fits the data. (Make sure your calculator is in the radian mode!)
