Answer:
P = $900
Step-by-step explanation:
Simple Interest Formula: [tex]A = P(1+rt)[/tex]
Where A is the final amount,
P = Principal
r = Interest Rate in Percent or [tex]\frac{r}{100}[/tex] per annum
t = time in years
From the information given in the question,
A = $918
r = 2% per annum or [tex]\frac{2}{100}[/tex]
t = 1 year
Lets substitute these values to find P, the principal.
[tex]P(1+(\frac{2}{100} )(1))=918\\P(1+0.02)=918\\1.02P=918\\P = \frac{918}{1.02} \\=$900[/tex]
Therefore, P = $900

The graph of the invertible function f is shown on the grid below.
Answer:
4
Step-by-step explanation:
→ We go up the y axis to 6 and read of the x coordinate which is 4. This is because an inverse function does the the opposite i.e. if f ( x ) = y
f⁻¹ ( y ) = x.
Part 1. Using the two functions listed below, insert numbers in place of the letters a, b, c, and d so that f(x) and g(x) are inverses.
f(x)=
x+a
b
g(x)=cx−d
Part 2. Show your work to prove that the inverse of f(x) is g(x).
Part 3. Show your work to evaluate g(f(x)).
Part 4. Graph your two functions on a coordinate plane. Include a table of values for each function. Include five values for each function. Graph the line y = x on the same graph.
Task 2
Part 1. Create two radical equations: one that has an extraneous solution, and one that does not have an extraneous solution. Use the equation below as a model:
a√x+b+c=d
Use a constant in place of each variable a, b, c, and d. You can use positive and negative constants in your equation.
Part 2. Show your work in solving the equation. Include the work to check your solution and show that your solution is extraneous.
Part 3. Explain why the first equation has an extraneous solution and the second does not.
See below for the solution to the inverse function and the rational equation
The function and the inverseCreate functions f(x) and g(x)
The functions are given as:
f(x) = x + a/b
g(x) = cx − d
Let a = 4 and b = 2.
So, we have:
f(x) = x + 4/2
Rewrite as:
y = x + 2
Swap x and y
x = y + 2
Make y the subject
y = x - 2
So, we have:
g(x) = x - 2
So, the functions are:
f(x) = x + a/b ⇒ f(x) = x + 4/2
g(x) = cx − d ⇒ g(x) = x - 2
Show that the functions are inverse functions
In (a), we have:
f(x) = x + 4/2
g(x)= x - 2
If the functions are inverse functions, then:
f(g(x)) = x
We have:
f(x) = x + 4/2
This gives
f(g(x)) = g(x) + 4/2
This gives
f(g(x)) = x - 2 + 4/2
Evaluate
f(g(x)) = x
Evaluate g(f(x))
In (a), we have:
f(x) = x + 4/2
g(x)= x - 2
We have:
g(x)= x - 2
This gives
g(f(x)) = f(x) - 2
This gives
g(f(x)) = x + 4/2 - 2
Evaluate
g(f(x)) = x
Graph the functions

Radical equationsCreate the equations
The form of the equations is given as:
[tex]a\sqrt{x + b} + c= d[/tex]
So, we have:
[tex]\sqrt{4x + 5} + 1 = 0[/tex] --- has extraneous solution
[tex]2\sqrt{3x - 1} + 2 = 8[/tex] --- has no extraneous solution
The equation solution
Equation 1 with extraneous solution
[tex]\sqrt{4x + 5} + 1 = 0[/tex]
Subtract 1 from both sides
[tex]\sqrt{4x + 5} = -1[/tex]
Square both sides
4x + 5 = 1
Evaluate the like terms
4x = -4
Divide by 4
x = -1
Substitute x = -1 in [tex]\sqrt{4x + 5} + 1 = 0[/tex] to check
[tex]\sqrt{4(-1) + 5} + 1 = 0[/tex]
[tex]\sqrt{-4 + 5} + 1 = 0[/tex]
[tex]\sqrt{1} + 1 = 0[/tex]
Evaluate the root
[tex]1 + 1 = 0[/tex]
[tex]2= 0[/tex] --- false
Equation 2 without extraneous solution
[tex]2\sqrt{3x - 1} + 2 = 8[/tex]
Subtract 2 from both sides
[tex]2\sqrt{3x - 1} = 6[/tex]
Divide by 2
[tex]\sqrt{3x - 1} = 3[/tex]
Square both sides
3x - 1 = 9
Evaluate the like terms
3x = 10
Divide by 3
x = 10/3
Substitute x = x = 10/3 in [tex]2\sqrt{3x - 1} + 2 = 8[/tex] to check
[tex]2\sqrt{3 * \frac{10}{3} - 1} + 2 = 8[/tex]
[tex]2\sqrt{10 - 1} + 2 = 8[/tex]
[tex]2\sqrt{9} + 2 = 8[/tex]
Evaluate the root
[tex]2*3 + 2 = 8[/tex]
[tex]8 = 8[/tex] --- true
Why the equations have (or do not have) an extraneous solution
The first equation has an extraneous solution because the solution is false for the original equation and the second does not have an extraneous solution because the solution is true for the original equation

Solve for all of the missing angles in the rhombus below, given that m∠3 = 54°. (Round to the nearest tenth as needed.)
The measure of angles 1, 2, 4, and 5 are 54 degrees, 90 degrees, 36 degrees, and angle 36 degrees.
What is a rhombus?A rhombus is a two-dimensional shape having four parallel opposite pairs of straight, equal sides. This shape resembles a diamond and is what you'd find on a deck of cards to represent the diamond suit. Rhombuses can be encountered in a variety of common situations.
We have shown the rhombus in the picture.
As we know the diagonals bisect at a 90-degree angle.
So angle 2 = 90 degree
angle 1 = angle 3
angle 1 = 54 degrees
angle 1 + angle 2 + angle 5 = 180
54 + 90 + angle 5 = 180
angle 5 = 36 degrees
angle 5 = angle 4 = 36 degrees
Thus, the measure of angles 1, 2, 4, and 5 are 54 degrees, 90 degrees, 36 degrees, and angle 36 degrees.

For the training adaptation of maximum strength, what is the recommended number of repetitions per set? 1 to 5 repetitions 1 to 6 repetitions More than 15 repetitions 6 to 12 repetitions
For the training adaptation of maximum strength, 1 to 5 repetitions per set is recommended.
The one-repetition maximum test, also called a one-rep max or 1RM, is used to find out the heaviest weight you can lift just once.
If Maximal strength is desired, it is best achieved by performing repetitions at 85 to 100 % of the one-repetition maximum (1RM).
Formula to find the repetition is
weight used x (reps done x 0.33 + 1) = 1RM
so,
Reps done = {{1RM/weight used} - 1}/ 0.33
By this find the no of reps are recommended for maximum strength.
The maximum strength is achieved by doing the number of reps by 85 to 100% of the value of 1 RM.
So,
For the training adaptation of maximum strength, 1 to 5 repetitions per set is recommended.

We got the value of [tex]e=\frac{78}{7}[/tex] by solving the given equations [tex]3x+2y=26[/tex] and [tex]5x+y=26[/tex] by reduction method.
What is reduction method?The reduction or elimination approach includes using arithmetic operations between equations to produce equivalent equations with fewer unknowns that are simpler to analyze and evaluate.
Given equations are
[tex]3x+2y=26[/tex] .........(1)
[tex]5x+y=26[/tex] ...........(2)
We need to find the value of [tex]e=x+y[/tex]
Simplifying the given equation (2) and we get
[tex]5x+y=26\\\Rightarrow y=26-5x[/tex]................(3)
Now, substitute the equation (3) in equation (1) and we get
[tex]3x+2(26-5x)=26\\\Rightarrow 3x+52-10x=26\\\Rightarrow -7x+52=26\\\Rightarrow -7x=26-52\\\Rightarrow -7x=-26\\\Rightarrow x=\frac{26}{7}[/tex]
Substitute the value of x in equation (3), we get

Given f(x) = -5x + 2, determine each of the following:
a) f(-1)
b) f^-1(7)
c) f^-1(-43)
Answer:
a) 7
b) -1
c) 9
Step-by-step explanation:
a) Substitute -1 into the x's of the function.
f(-1) = -5(-1) + 2
f(-1) = 5 + 2
f(-1) = 7
b) f^-1(7) means: find the inverse of the function with 7 substituted as x.
Let y = f(x)
y = -5x + 2
5x = 2 - y
x = 2 - y / 5
f^-1(x) = 2 - x / 5
f^-1(7) = 2 - 7 / 5
f^-1(7) = -5/5
f^-1(7) = -1
c) We have already found the inverse of the- original function. Substitute -43 into the x's of the inverse function.
f^-1(-43) = 2 - (-43) / 5
f^-1(-43) = 2 + 43 / 5
f^-1(-43) = 45/5
f^-1(-43) = 9

In which quadrant is the endpoint of the segment that defines the angle?We know that if:
cos(θ) > 0, then we are on the first or fourth quadrantsin(θ) > 0, then we are on first or second quadrant.Here we know that:
sec(θ) < 0
And we know that:
sec(θ) = 1/cos(θ)
Then we have cos(θ) < 0
We also have that:
sec(θ)*csc(θ) > 0
Because sec(θ) < 0, we must have that csc(θ) < 0.
Remember: csc(θ) = 1/sen(θ)
Then sen(θ) < 0.
Then we have the two conditions:
sen(θ) < 0
cos(θ) < 0
