State if the given functions are inverses.
1. g(x) = 4 + (7/2)x
f(x) = 5 - (4/5)x
Find the inverses of each function.
2. g(n) = (8/3)n + 7/3
3. g(x) = 1 - 2x^3
Answer:
1) The functions are not inverses.
\(\textsf{2)} \quad g^{-1}(n)=&\dfrac{3}{8}n-\dfrac{7}{8}\)
\(\textsf{3)} \quad g^{-1}(x)&=\sqrt[3]{\dfrac{1}{2}-\dfrac{1}{2}x}\)
Step-by-step explanation:
Question 1The inverse composition rule states that if two functions are inverses of each other, then their compositions result in the identity function.
Given functions:
\(g(x) = 4 + \dfrac{7}{2}x \qquad \qquad f(x) = 5 - \dfrac{4}{5}x\)
Find g(f(x)) and f(g(x)):
\(\begin{aligned} g(f(x))&=4+\dfrac{7}{2}f(x)\\\\&=4+\dfrac{7}{2}\left(5 - \dfrac{4}{5}x\right)\\\\&=4+\dfrac{35}{2}-\dfrac{14}{5}x\\\\&=\dfrac{43}{2}-\dfrac{14}{5}x\\\\\end{aligned}\) \(\begin{aligned} f(g(x))&=5 - \dfrac{4}{5}g(x)\\\\&=5 - \dfrac{4}{5}\left(4 + \dfrac{7}{2}x \right)\\\\&=5-\dfrac{16}{5}-\dfrac{14}{5}x\\\\&=\dfrac{9}{5}-\dfrac{14}{5}x\end{aligned}\)
As g(f(x)) or f(g(x)) is not equal to x, then f and g cannot be inverses.
\(\hrulefill\)
Question 2To find the inverse of a function, swap the dependent and independent variables, and solve for the new dependent variable.
Calculate the inverse of g(n):
\(\begin{aligned}y &= \dfrac{8}{3}n + \dfrac{7}{3}\\\\n &= \dfrac{8}{3}y + \dfrac{7}{3}\\\\3n &= 8y + 7\\\\3n-7 &= 8y\\\\y&=\dfrac{3}{8}n-\dfrac{7}{8}\\\\g^{-1}(n)&=\dfrac{3}{8}n-\dfrac{7}{8}\end{aligned}\)
Calculate the inverse of g(x):
\(\begin{aligned}y &= 1-2x^3\\\\x &= 1-2y^3\\\\x -1&=-2y^3\\\\2y^3&=1-x\\\\y^3&=\dfrac{1}{2}-\dfrac{1}{2}x\\\\y&=\sqrt[3]{\dfrac{1}{2}-\dfrac{1}{2}x}\\\\g^{-1}(x)&=\sqrt[3]{\dfrac{1}{2}-\dfrac{1}{2}x}\\\\\end{aligned}\)
Answer:
1.
If the composition of two functions is the identity function, then the two functions are inverses. In other words, if f(g(x)) = x and g(f(x)) = x, then f and g are inverses.
For\(\bold{g(x) = 4 + \frac{7}{2}x\: and \:f(x) = 5 -\frac{4}{5}x}\), we have:
\(f(g(x)) = 5 - \frac{4}{5}(4 + \frac{7}{2}x)\\ =5 - \frac{4}{5}(\frac{8+7x}{2})\\=5 - \frac{2}{5}(8+7x)\\=\frac{25-16-14x}{5}\\=\frac{9-14x}{5}\)
\(g(f(x)) = 4 + (\frac{7}{5})(5 - \frac{4}{5}x) \\=4 + (\frac{7}{5})(\frac{25-4x}{5})\\=4+ \frac{175-28x}{25}\\=\frac{100+175-28x}{25}\\=\frac{175-28x}{25}\)
As you can see, f(g(x)) does not equal x, and g(f(x)) does not equal x. Therefore, g(x) and f(x) are not inverses.
Sure, here are the inverses of the functions you provided:
2. g(n) = (8/3)n + 7/3
we can swap the roles of x and y and solve for y to find the inverse of g(n). In other words, we can write the equation as y = (8/3)n + 7/3 and solve for n.
y = (8/3)n + 7/3
n =3/8*( y-7/3)
Therefore, the inverse of g(n) is:
\(g^{-1}(n) = \frac{3}{8}(n - \frac{7}{3})=\frac{3}{8}*\frac{3n-7}{3}=\boxed{\frac{3n-7}{8}}\)
3. g(x) = 1 - 2x^3
We can use the method of substitution to find the inverse of g(x). We can substitute y for g(x) and solve for x.
\(y = 1 - 2x^3\\2x^3 = 1 - y\\x = \sqrt[3]{\frac{1 - y}{2}}\)
Therefore, the inverse of g(x) is:
\(g^{-1}(x) =\boxed{ \sqrt[3]{\frac{1 - x}{2}}}\)

What is the surface area of this cylinder?
Use ≈ 3.14 and round your answer to the nearest hundredth.
The radius is 10mm and the height is 5mm
Answer:
942 square millimeters.
Step-by-step explanation:
The formula for the surface area of a cylinder is:
S = 2πr^2 + 2πrh
where S is the surface area, r is the radius, and h is the height.
Substituting the given values, we get:
S = 2 x 3.14 x 10^2 + 2 x 3.14 x 10 x 5
S = 628 + 314
S = 942
Therefore, the surface area of the cylinder is 942 square millimeters.

Answer:
m<2 = 70degrees
m<3 = 70degrees
m<4 = 110degrees
m<5 = 110degrees
m<6 = 70degrees
m<7 = 70degrees
m<8 = 110degrees
Step-by-step explanation:
A line has the angles of 180 degrees so if m<1 is 110 then m<2 must be 70degrees. Then m<4 is opposite side of m<1 so it has to be the same number of degrees and the same for m<3 is the opposite side of m<2.

The distance between points A and C is 5 units.
Here, we have to find the distance between two points A(-2, -3) and C(3, -3), we can use the distance formula:
Distance = √((x₂ - x₁)² + (y₂ - y₁)²).
Where (x₁, y₁) are the coordinates of point A and (x₂, y₂) are the coordinates of point C.
Given:
Point A: (-2, -3)
Point C: (3, -3)
Plugging these values into the distance formula:
Distance = √((3 - (-2))² + (-3 - (-3))²)
Distance = √(5² + 0²)
Distance = √25
Distance = 5.
So, the distance between points A and C is 5 units.

What are the names of a circle with H
If the length of HJ is 7 unit then the length of EI is 14 unit.
What is a circle?A circle is a shape consisting of all points in a plane that are given the same distance from a given point called the center.
We are given a circle with center H.
Therefore, the radius of the circle is found as; HJ
Then the Diameter is the line from one point in the circle to the other point through the center of the circle.
Diameter of the circle = EI
Since we know that One of the theorems of a circle states that the angles in the same segments or on the same chord are equal.
Then the name of the chord is FG.
If the length of HJ is 7 unit then the length of EI is;
EI = 2 HJ
EI = 14 unit.

The number 1234567 cannot be written as a sum of two squares.
Let q = x^2+y^2,
Let a and b be two even numbers, such that
a= 2x and b = 2y
then
n = (2x)^2 + (2y)^2 = 4 (x^2+y^2)
implies n = 4q
Let a and b be two odd numbers, such that
a = 2x+1 and b = 2y+1
then
n = (2x+1)^2 + (2y+1)^2 = 4x^2+4y^2+1 = 4q+2
Let a be an even number and b be an odd number, such that
a= 2x and b = 2y+1

n = (2x)^2 + (2y+1)^2 = 4q+1

tanx sinx+ secx cos^2x. Explain how you do it
Answer:
First, remember that:
\(tan(x) = \frac{sin(x)}{cos(x)}\)
and:
\(sec(x) = \frac{1}{cos(x)}\)
Then we can rewrite the expression:
\(tan(x)*sin(x) + sec(x)*cos^2(x) = A\)
Where A is an equivalent expression.
as:
\(\frac{sin(x)}{cos(x)} *sin(x) + \frac{1}{cos(x)}*cos^2(x) = A\)
Then this is:
\(\frac{sin^2(x)}{cos(x)} + cos(x) = A\)
Now we can multiply both sides by cos(x), then:
\((\frac{sin^2(x)}{cos(x)} + cos(x))*cos(x) = A*cos(x)\)
\(sin^2(x) + cos^2(x) = A*cos(x)\)
And we know that the left term of the above equation is equal to 1, then:
\(1 = A*cos(x)\)
\(\frac{1}{cos(x)} = sec(x) = A\)
And A is equivalent to the original expression, then we get:
\(tan(x)*sin(x) + sec(x)*cos^2(x) = sec(x)\)
The simplification of the expression is sec(x)

Based on this triangle, what statement about x is true?

x = 62 because 147 – 85 = 62 and 85 + 62 = 147
x = 95 because 180 – 85 = 95 and 85 + 95 = 180
x = 118 because
180 147 + 85
33 + 85
=118
Answer:
B. x = 62 because 147 – 85 = 62 and 85 + 62 = 147
Step-by-step explanation:
We are given that
\(\angle ABC=85^{\circ}\)
Exterior angle=\(147^{\circ}\)
We have to find the value of x.
We know that
Exterior angle=Sum of opposite interior angles of triangle
Using the property
\(x+85=147\)
Subtract 85 from both sides we get
\(x=147-85\)
\(x=62\)
Option B is true.
B. x = 62 because 147 – 85 = 62 and 85 + 62 = 147
