Answer:
The inverse of a function, denoted as f^-1 (x), is a new function that "undoes" the original function. To find the inverse of a function, you need to switch the x and y variables and then solve for y. To find the inverse of f(x) = 1/3 x - 5, you need to switch the x and y variables and then solve for y:
Step-by-step explanation:
To solve for y, you need to get x alone on one side of the equation:
x + 5 = 1/3 y
3x + 15 = y
The inverse of f(x) = 1/3 x - 5 is f^-1 (x) = 3x + 15
It is important to note that not all functions have an inverse, only functions that are one-to-one or "injective" functions have inverses.
Answer: 3x + 15 = the inverse function of f(x)
Explanation:
First of all, arrange the equation and leave the "x" alone.
x/3 - 5 = y (Multiply both sides by 3)
x - 15 = 3y (Then, leave "x" alone)
x = 3y + 15 (As the final step, change x and y variables.)
y = 3x + 15 (This is the inverse function of f(x).)

Find the solutions of the equation on the indicated interval. List the smaller answer first. Round to 3 decimal places. 3 cos ( x ) + 4 = 5 with − π ≤ x ≤ π .
Answer:
Step-by-step explanation:
The solutions to this equation are x = 1.273 and x = -0.273.
When x = 1.273, 3 cos (x) + 4 = 5.
When x = -0.273, 3 cos (x) + 4 = 5.
Rounding to 3 decimal places, the solutions to the equation on the indicated interval are x = 1.273 and x = -0.273.
Find the equation of the line that passes through (1,3) and is perpendicular to y=2x+3. Leave your answer in the form ax+by=c Where a, b and c are integers.
Answer:
2y+x=7
Step-by-step explanation:
The equation of a line is in the form:
[tex]y = mx + c[/tex]
where m is the gradient and c is the y-intercept.
In the equation y=2x+3 the gradient is 2, so to find the perpendicular gradient, it is the negative reciprocal, or in other words, flip the number upside down and make it negative:
[tex]2 = \frac{2}{1} [/tex]
[tex] \frac{2}{1} \: flipped \: upside \: down = \frac{1}{2} [/tex]
[tex] make \: \frac{1}{2} \: negative = - \frac{1}{2} [/tex]
So the gradient for the point (1, 3) is -1/2
Using y=mx+c to find c (the y-intercept) where y=1, m=-1/2, x=1, substitute these values in:
[tex]y = mx + c[/tex]
[tex]3 = - \frac{1}{2} (1) + c[/tex]
[tex]3 = - \frac{1}{2} + c[/tex]
[tex]3 + \frac{1}{2} = c[/tex]
[tex]c = \frac{7}{2} [/tex]
So the equation is:
[tex]y = - \frac{1}{2} x + \frac{7}{2} [/tex]
We need to write this in the form ax+by=c, so multiply everything by 2 to get rid of the fractions on the right:
[tex]2y = - x + 7[/tex]
Bring x to the left side by adding it:
[tex]2y + x = 7[/tex]
This is now in the form ax+by=c

If In ΔEFG, e = 690 inches, ∠F=94° and ∠G=46° then the length of g is 800 inches.
What is Trigonometry?Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.
The sum of interior angles of a triangle are 180 degrees.
In ΔEFG, e = 690 inches, ∠F=94° and ∠G=46
We need to find the ∠E then the length of g.
∠E+∠F+∠G=180
∠E+94+46=180
∠E+140=180
∠E=40 degrees

Suppose that you made repeated measurements of your height. If you used good technique, would you expect the range of measurements to be large or small? Explain your answer.
Answer:
Step-by-step explanation:
If you used good technique, you would expect the range of measurements to be small. Good technique would include using a measuring instrument that is calibrated correctly, measuring in the same position and at the same time of day, and being consistent in how you position your body during the measurement. All of these factors would help to reduce the amount of measurement error and therefore lead to a smaller range of measurements.

Find the measure of the given angle
Answer:
A= 110 degrees AND B= 140 degrees.
Y= 112 degrees and X= 157 degrees.
Step-by-step explanation:
Triangle XYZ is an isocoles triangle, because it has two congruent sides. 70 degrees is a measurement of an angle opposite of one of those congruent sides, so angle YXZ is also 70 degrees. By the triangle angle sum theorem, we can say that the measurement of angle YZX is 40 degrees. So, for the first triangle, by the linear pairs theorem, we can find the two missing angles.
A= 110 degrees AND B=140 degrees.
For the triangle on the right, we can use the triangle angle sum theorem to say that angle BDC is 68 degrees. Then, we can say that by the by the linear pairs theorem that angle ADE is 112 degrees. From there, we need to look at the 23 degree measurement on the lower right triangle. We can see that the angle steadily rises on that line and then we can take 180-23 by the linear pairs theorem to conclude than angle BEA is 157 degrees. This can be confirmed by looking at the two innermost angles in the top right triangle. If you take 180-23-112, you will get 45. If you add 45 to 112, you will get 157.
Y= 112 degrees and X= 157 degrees.

What is interest and its types(Simple and compound interest)?
Interest is the cost of borrowing money, where the borrower pays a fee to the lender for the loan. The interest, typically expressed as a percentage, can be either simple or compounded. Simple interest is based on the principal amount of a loan or deposit. In contrast, compound interest is based on the principal amount and the interest that accumulates on it in every period. Simple interest is calculated only on the principal amount of a loan or deposit, so it is easier to determine than compound interest.
The formula for these are
Simple Interest= P×r×n
where:
P=Principal amount
r=Annual interest rate
n=Term of loan, in years
Compound Interest=P×(1+r)^t−P
where:
P=Principal amount
r=Annual interest rate
t=Number of years interest is applied
Here,
Interest rate will be risk percentage + LIBOR
i.e.4.8%
Hence, the interest can be found by using formula for simple interest

the ratio of height and length of a store room is 5:4 and the ratio of height and breadth is 2:3. find the area of the floor of the store room if the total area of the four walls of the store room is 2760m^2
Answer: The area of the floor of the store room is 1080 m^2
Step-by-step explanation:
We can begin by using the information provided about the ratios of the dimensions of the store room to set up a system of equations.
Let's call the height of the store room h, the length l, and the breadth b.
From the first ratio given, we know that:
h/l = 5/4
From the second ratio given, we know that:
h/b = 2/3
We can also use the information about the total area of the four walls to set up another equation.
The total area of the four walls is the sum of the area of the top and bottom walls (length x height) and the area of the two side walls (breadth x height).
So we have:
2lh + 2bh = 2760
We can now use the first two equations to solve for one of the variables in terms of the other two.
We can cross-multiply and simplify the first equation:
l = (4/5)h
We can cross-multiply and simplify the second equation:
b = (3/2)h
We can now substitute these expressions for l and b into the equation for the total area of the four walls:
2(4/5)h^2 + 2(3/2)h^2 = 2760
Solving for h, we get:
h = 30
Now that we know the value of h, we can use the equations l = (4/5)h and b = (3/2)h to find the values of l and b.
l = (4/5)h = (4/5)(30) = 24
b = (3/2)h = (3/2)(30) = 45
Now we have all the information we need to find the area of the floor, which is the product of the length and breadth of the store room
Area of floor = lb = 2445 = 1080 m^2
Explanation: By using the information about the ratios of the dimensions of the store room and the total area of the four walls, we set up a system of equations and used algebra to solve for the height, length and breadth of the store room. With this information, we were able to find the area of the floor of the store room.

Graphing Lines How would you graph 10x-3y=15
Answer:
Step-by-step explanation:
To graph 10x-3y=15, start by rearranging the equation to the slope-intercept form of y = mx + b, where m = the slope and b = the y-intercept. 10x-3y=15 becomes 3y = 10x - 15. Solve for y by dividing both sides by 3 to get y = (10/3)x - 5.
Now that the equation is in the slope-intercept form, draw a graph on a coordinate plane. Start by plotting the y-intercept at (0, -5). Next, use the slope of 10/3 to determine the rise and run of the line. The rise is +10 and the run is +3. Starting at the y-intercept, draw a line that moves up 10 and to the right 3, and continue doing this until you reach the end of the graph. This line is the graph of 10x-3y=15.
Answer:
y=10/3x+5
(0,5), (3,15)
Step-by-step explanation:
First, put the graph in slope-intercept form. We can do this by subtracting 10x from both sides.
-3y=-10x-15
Next, we divide by -3.
y=10/3x+5
If you don't know how to graph an equation with slope-intercept form,
it is in the format of y=mx+b, where m is the slope (in this case, 10/3) and b is the y-intercept (in this case 5, or (0,5)). First graph the y-intercept.
(0,5).
Then implement the slope. Here we would go up by 10 and then go right by 3. This makes our second point (3,15).
Now that we have two points (0,5) and (3,15), just construct your line.
