Answer:
\(f^{-1}\left(f(576)\right)=\boxed{576}\)
\(f^{-1}(-7)+f(-7)=\boxed{13}\)
Step-by-step explanation:
The inverse of an invertible function with the domain of all real numbers is obtained by reflecting the original function across the line y = x, which swaps the input and output values of the function. Therefore, (x, y) → (y, x).
Given table:
\(\begin{array}{lrrrrrr}\vphantom{\dfrac12}x&-7&11&-13&6&5&-9\\\cline{1-7}\vphantom{\dfrac12}f(x)&7&12&8&-7&13&5\end{array}\)
Inverse function:
\(\begin{array}{lrrrrrr}\vphantom{\dfrac12}x&7&12&8&-7&13&5\\\cline{1-7}\vphantom{\dfrac12}f^{-1}(x)&-7&11&-13&6&5&-9\end{array}\)
If we have a function f(x), the inverse function is denoted as f⁻¹(x), and it has the property that f⁻¹(f(x)) = x for all valid inputs x in the domain of f(x).
Therefore:
\(\large\boxed{f^{-1}\left(f(576)\right)=576}\)
The value of f(-7) is the value of f(x) when x = -7. Therefore, reading from the original table, f(-7) = 7.
The value of f⁻¹(-7) is the value of f⁻¹(x) when x = -7. Therefore, reading from the inverse function table, f⁻¹(-7) = 6.
Therefore:
\(\large\boxed{\begin{aligned}f^{-1}(-7)+f(-7)&=6+7\\&=13\end{aligned}}\)

Step-by-step explanation:
The number of pieces of popcorn in a large movie theatre popcorn bucket is normally distributed, with a mean of 1610 and a standard deviation of 10. Approximately what percentage of buckets contain between 1600 and 1620 pieces of popcorn?
Approximately 68%
Approximately 75%
Approximately 95%
Approximately 99.7%
Answers
Answer:
A. Approximately 68%
Step-by-step explanation:
The number of pieces of popcorn in a bucket is normally distributed.
Mean = μ = 1610
Standard deviation = б = 10
We know that in a normal distribution, approximately 34% of bags will fall within one standard deviation on one side. On both sides within the range of 1 standard deviation, 34 + 34 = 68 % of bags will fall.
A table of normal distribution of the mean is attached for better understanding.
Our range is:
1600 to 1620
1610 - 10 to 1610 + 10
μ ± б
mean ± 1 standard deviation
Our range is within 1 standard deviation. Hence, Approximately 68% of buckets contain between 1600 and 1620 pieces of popcorn.

Answer:
Y= mx + b
so Y = 1/3x + 2
just substitute
Now, we shall use points (3,2) as the substitutes for the solution for b, which 3 would be the input and 2 would be y.
Therefore, 2 = 1/3(3) + b
2 = 1 + b, therefore, one would be subtracted from 2 which would give us the answer of b equaling to one. Thus, y = 1/3x + 1

A certain blueprint shows two fences. Fence A is 1 1 4 yards long but is 1 1 2 inches long on the blueprint. What is the unit rate for inches per yard on this blueprint? If fence B is 5 yards long, how long is fence B on the blueprint?
Answers
Fence B in blueprint is 4.91 yards long (or 4.91071428572)
Step-by-step explanation:
If fence B is 114 yards long IRL and 112 in blueprint, then that means that every 114 yards, it's substracted 2, or every 57 it's substracted 1.
So 5 / 57 = 0.08771929824
You substract: 5 - 0.08771929824 = 4.91071428572
Simplified it's 4.91 Yards
Answer:
1.02 in/yd

Answers
Answer:
32 degrees
Step-by-step explanation:
The sum of all angles in a triangle is 180 degrees.
A right angle (The one marked by a small square on the bottom left) measures 90 degrees.
You're given that the other two angles in the triangle measure 58 and x degrees.
To find x, we'll find the sum of all angles, and equate it to 180.
The sum of all angles = 90 + 58 + x = 148 + x degrees
\(148 + x = 180 \text{ // -148}\\\cancel{148 -148} + x = 180 - 148\\x = 32^{\circ}\)

Answers
Answer:
x = 18
Step-by-step explanation:
This problem can be solved using concept of Pythagoras theorem.
Pythagoras theorem states that in a right angled triangle, if "a" and "b" are sides containing the right angle and h is hypotenuse then the relation between them is \(a^2 + b^2 = h^2\)
_________________________________________
Given in the problem
a = 24
b = x
h = x+12
applying Pythagoras theorem
\(24^2 + x^2 = (x+12)^2\\=> 576 + x^2 = x^2 + 24x + 144\\=>576 = x^2 + 24x + 144 - x^2\\=> 576 = 24x + 144 \\=> 576 - 144= 24x\\=> 432 = 24x\\=> x = 432/24 = 18\)
for (x+12)^2 we have used formula \((a+b)^2 = a^2 + 2ab + b^2\)
Thus, value of x is 18.

A photo of a beetle in a science book is increased to 778% as large as the actual size. If the beetle is 15 mm, what is the size of the beetle in the photo
Answers
Answer:
Step-by-step explanation:
If the beetle is 15 mm in actual size, and the photo is increased to 778% of the actual size, then we can find the size of the beetle in the photo by multiplying its actual size by 7.78:
Size of beetle in photo = Actual size of beetle x 7.78
Substituting the given value of the actual size, we get:
Size of beetle in photo = 15 mm x 7.78
= 116.7 mm
Therefore, the size of the beetle in the photo is 116.7 mm.

The area of the circular shaded region is given as follows:
A = 50.24 square yards.
How to calculate the area of a circle?The area of a circle of radius r is given by the multiplication of π and the radius squared, as follows:
A = πr²
The radius of a circle represents the distance between the center of the circle and a point on the circumference of the circle, while the diameter of the circle is the distance between two points on the circumference of the circle, on a segment that passes through the center. Hence, the diameter’s length is twice the radius length.
The circumference of a circle of radius r is given as follows:
C = 2πr.
Hence the radius of the inner circle is given as follows:
6.28r = 18.84
r = 18.84/6.28
r = 3 yd.
The radius of the outer circle is of 3 + 2 = 5 yd, hence the area of the shaded region is given as follows:
A = 3.14 x (5² - 3²)
A = 50.24 square yards.
