When the product of two numbers is 40 and one of the numbers is 8/15, the other number can be found by dividing 40 by 8/15, which is 937.5.
Explanation:The question is asking for the other number when the product of two numbers is 40 and one of the numbers is given as 8/15. To answer this, we need to use the concept that the product of two numbers is equal to one number multiplied by the other. Therefore, to find the missing number, we need to divide 40 (the product) by the given number (8/15).
So, the calculation will look like this: 40 ÷ (8/15) = 7500/8 = 937.5.
Thus, the other number is 937.5 .

Given f(x) = ax – b, what is f-1(x)?
A) x+b/a
B) 1/ax-b
C) 1/ax+b
ANSWER
The correct answer is A
[tex]f^{-1}(x)=\frac{x+b}{a}[/tex]
EXPLANATION
Given [tex]f(x)=ax-b[/tex].
We can find the inverse by taking the steps.
1. Let [tex]y=ax-b[/tex]
2. Interchange x and y
[tex]x=ay-b[/tex]
3. Make y the subject
[tex]x+b=ay[/tex]
[tex]\frac{x+b}{a}=y[/tex]
The new function we got now is the inverse of f(x)
[tex]f^{-1}(x)=\frac{x+b}{a}[/tex]
x + b/a Replace f(x) with y, interchange x and y and solve for y.
How to express exponential equation, 3^c = 27 , as a logarithmic equation
If you consider the logarithm base 3 of both sides, you have
[tex] \log_3(3^c) = \log_3(27) [/tex]
You can use a rule of logarithms that allow you to turn exponents into multiplicative factors:
[tex] \log_a(b^c) = c\log_a(b) [/tex]
So the equation becomes
[tex] c\log_3(3)=\log_3(27) [/tex]
Now, by definition, you have
[tex] \log_a(b)=c \iff a^c=b [/tex]
So, you have
[tex] \log_3(3)=x \iff 3^x=3 \iff x = 1,\quad \log_3(27)=y \iff 3^y=27\iff y=3 [/tex]
So, the equation becomes
[tex] 1\cdot c = 3 \iff c=3 [/tex]
[tex]log_{3}[/tex]27 = c
using the law of logs : [tex]log_{b}[/tex] x = n ⇔ x = [tex]b^{n}[/tex]
given [tex]3^{c}[/tex] = 27 then
[tex]log_{3}[/tex] 27 = c

When is cos (x) = 0? at 90° (aka π/2)
Answer: [tex]\frac{\pi}{2}[/tex]
Answer: Hello there!
We have the function f(x) = exp(-sin(x)) and we want to see in wich point the slope is 0.
This is equivalent to see when f'(x) = 0
where f'(x) is the derivative of f(x)
Then the first step is derivate the function f(x)
if we have a function of the form g(h(x)), his derivate is:
g'(h(x))*h'(x)
In our case, g(x) = exp(x) and h(x) = - sin(x)
then f'(x) = exp(-sin(x))*(-cos(x))
Now we know that exp(-sin(x)) is never equal to 0, then we need to se when the cosine is equal to zero.
cos(90°) = 0, and 90° is equivalent to pi/2
Then f'(pi/2) = exp(-sin(pi/2))*(-cos(pi/2)) = 0
this means that the function f(x) has a slope of 0 in the point x = pi/2

Step-by-step explanation:
Julio cubes a number and then takes the cube root of the result.He ends up with 20.What number did julio start with
Julio initially started with the number 20, because cubing the number and then taking the cube root returns the original number.
If Julio cubes a number and then takes the cube root of the result, and ends up with 20, then the number he started with is also 20. This is because the cube of a number n is n
to the power of 3 (n³), and the cube root of a number is the inverse operation, which will return the original number. In symbolic form, if n is cubed to get n³, then taking the cube root of n³ will return n. Since Julio ends up with 20, the number he started with must have been 20.

The problem then looks like this: 5/9 + 3 1/3
To make the problem easier you change the mixed number (3 1/3) to an improper fraction which is 10/3
Because its 5/9 + 10/3 you multiply 10 and 3 and get 30, and you keep the LCD (least common denominator) which is 9
Finally you add 5 + 30 = 35 and have 9 as your denominator

What are the domain and range of each relation?
Drag the answer into the box to match each relation.
Answers:
The domain of the graph is {-3, -1, 1, 4}. The range of the graph is {-4, -1, 1, 4}
The domain of the set of ordered pairs is {-4, -3, 1}. The range of the set of ordered pairs is {1, 3, 4}
====================================================
Recall that the domain is the set of allowed x values. All we do is list the unique x coordinates of each point which are -3, -1, 1 and 4. The range is the set of y values so we just list the unique y coordinates of each point which are -4, -1, 1 and 4.
The same will happen with the other problem as well. The set of points listed is pretty much identical to the first problem, but the points haven't been graphed, but instead their coordinates have been listed out. The first coordinate is the x coordinate. The second coordinate is the y coordinate. Each point is in the form (x,y).

K is the midpoint of segment HL . H has coordinates (1, -7 ) , and K has coordinates(-9, 3 ). Find the coordinates of other end point L.
The coordinates of the other endpoint L are (-19, 13).
If K is the midpoint of segment HL, we can use the midpoint formula to find the coordinates of point L.
The midpoint formula states that if you have the coordinates of two endpoints of a line segment and the coordinates of the midpoint, you can find the missing endpoint.
Let's denote the coordinates of point L as (x, y).
The midpoint formula is:
Midpoint =[tex]\(\left(\frac{{x_1 + x_2}}{2}, \frac{{y_1 + y_2}}{2}\right)\)[/tex]
Given:
Coordinates of K = (-9, 3)
Coordinates of H = (1, -7)
Let (x, y) be the coordinates of point L.
Using the midpoint formula for x-coordinates:
[tex]\(\frac{{1 + x}}{2} = -9\)[/tex]
Solving for x:
[tex]\(1 + x = -18\)[/tex]
[tex]\(x = -19\)[/tex]
Using the midpoint formula for y-coordinates:
[tex]\(\frac{{-7 + y}}{2} = 3\)[/tex]
Solving for y:
[tex]\(-7 + y = 6\)[/tex]
[tex]\(y = 13\)[/tex]
Therefore, the coordinates of the other endpoint L are (-19, 13).

This is a procedure to multiply mixed numbers. Then multiply the fractions and simplify the resulting fraction into a mixed number.
Explanation:The problem asked here is a multiplication problem with mixed numbers. First, let's convert 3 2/5 and 2 1/3 to improper fractions. For 3 2/5, multiply 5 (the denominator) and 3 (the whole number), then add 2 (the numerator). We get 17/5. For 2 1/3, multiply 3 (the denominator) and 2 (the whole number), then add 1 (the numerator). We get 7/3.
Now let's multiply the fractions. The resulting fraction is (17/5) x (7/3) = 119/15. This simplifies to 7 14/15.
So, 3 2/5 multiplied by 2 1/3 equals 7 14/15.

5(2x-1)/3 -4 =11 what does x =
Solve for x by simplifying both sides of the equation, then isolating the variable.
x = 5
To solve the equation 5(2x-1)/3 - 4 = 11 for x, you need to isolate the term containing x on one side and perform basic algebraic operations to find that x = 5.
Explanation:The mathematical equation in question is 5(2x-1)/3 - 4 = 11, which you can solve to find the value of x. First off, you should isolate the term including x on one side to simplify the equation. Multiply both sides by 3 to get rid of the division by 3. The equation then becomes: 5(2x-1) - 4*3 = 11*3, which simplifies to 5(2x-1) - 12 = 33. Then, add 12 to both sides to isolate the term containing x on one side: 5(2x-1) = 45. Next, divide both side by 5 so the equation becomes: 2x-1 = 9. Finally, add 1 then divide by 2 to solve for x, and you get x = 5.
