Answer:
15,625
Step-by-step explanation:
If f(x) = 5x then f ¹ you must label all numbers in the equation to make it easier, once done you will have 25(5¹)=125¹
125x125=15,625
The inverse function of the given function is x/5.
What is inverse function?Inverse function is represented by f⁻¹ with regards to the original function and the domain of the original function becomes the range of inverse function and the range of the given function becomes the domain of the inverse function. The graph of the inverse function is obtained by swapping (x, y) with (y, x) with reference to the line y = x.
Given that, f(x)=5x
Now, y=5x
Replace x by y and y by x, we get
x=5y
y=x/5
and f⁻¹(x)=x/5
Therefore, the inverse function of the given function is x/5.

How to find the simple interest rate if P=$4,000. T=2 years . And I= $320
And pls explain how I can find simple interest in every question bc I’m stressing about math finals
Answer:
3.2
Step-by-step explanation:
Formula to find the simple interest rate :
S.I. = [tex]\frac{PRT}{100}[/tex]
Formula to find R (simple interest rate) :
R = [tex]\frac{100*S.I.}{P*T}[/tex]
Since you have I (interest amount), we can use this formula instead :
R = [tex]\frac{I}{PT}[/tex]
R = [tex]\frac{320}{4,000*2}[/tex] = 4%/year or 0.04
Now plug this into the first formula
S.I. = [tex]\frac{4,000*0.04*2}{100}[/tex] = 3.2
i haven't done this in a while so hope this helps !!

Write the ratio 12:16:8 in simplest form
Answer:
[tex]\huge\boxed{\bf\: 3:4:2}[/tex]
Step-by-step explanation:
In the given ratio, [tex]12:16:8[/tex], we can see that all the 3 numbers in ratio are multiples of 4. Hence the lowest common multiple (LCM) of the given ratio = 4.
Now, let's divide the 3 numbers by 4.
[tex]12:16:8\\= \frac{12}{4}:\frac{16}{4}:\frac{8}{4}\\=\boxed{\bf\: 3:4:2}[/tex]
This ratio cannot be further simplified as they don't have any common multiples except for 1.
So, the simplified ratio = [tex]\boxed{\bf\: 3:4:2}[/tex]

Layla walked a total of 12 kilometers by making 4 trips to school. After 5 trips to school, how many kilometers will Layla have walked in total? Assume the relationship is directly proportional.
Answer:
[tex]=15km[/tex]
Explanation:
[tex]12[/tex] [tex]km[/tex] ÷ [tex]4[/tex]
[tex]=3[/tex] [tex]km[/tex] per trip to school
Now that we know that Layla walks 3 km to walk to school, we multiply that by 10
[tex]3[/tex] [tex]km[/tex] × [tex]5[/tex] [tex]trips[/tex]
[tex]=15[/tex] [tex]km[/tex]

The approximate value of log b to the nearest hundredth is 1.23
Laws of logarithmGiven the following logarithmic expressions
loog(5)b and log(9)48
Determine the value of log(9) 48
log(9)48 = 1.762
Equate log(5) b to 1.762 to log(5)b to determine the value of b
log(5)b = 1.762

A linear or nonlinear system of equations is called consistent if there is at least one set of values for the unknowns that satisfies each equation in the system—that is, when substituted into each of the equations, they make each equation hold true as an identity.
Let x represents the number of one-bedroom houses and y represents the number of two bedroom houses.
According to Question,
Total number of houses is 12 i.e. x + y = 12..........(i)
Total we have 88 windows in which 6 windows can be use in one bedroom house and 9 windows can be used in two bedroom house so,
6x + 9y = 88 ..................(ii)

Step-by-step explanation:
You have to simplify the brackets in turn.
3 times x^3- 7x+1 = 3x^3- 21x+ 3
then do 3 times x + 4= 3x + 12
you then add them all together, if they have a power add them, if they just have an x add them, and if they are just a number add them.
So it goes to 3x^3- 24x - 9,
this is because 3x^3 cant be added/ subtracted by anything, -24x is made from -21x- 3x, and -9 is made from 3 - + 12, so this means 3 - 12 = -9.

What is an angle?The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.
If the measure of the angle ∠RQT is 125°. Then the measure of the angles ∠RQS and ∠SQT will be
Then we have
∠RQS + ∠SQT = 125°
(3x - 10)° + (4x + 9)° = 125°
7x - 1 = 125°
7x = 126°
x = 18°
Then the measure of the angle ∠RQS will be
∠RQS = 3 × 18 - 10
∠RQS = 44°
Then the measure of the angle ∠SQT will be
∠SQT = 4 × 18 + 9

A complete graph of the polynomial function f is provided. Use your knowledge of the domain, range, behavior at each x intercept, end behavior, symmetry, local and global extreme values, and intervals of increasing and decreasing to select the best choice of the polynomial function, f.
The graph represents a polynomial graph, and the equation of the polynomial graph is f(x) = -(x + 5)³(x - 2)²
How to determine the equation?From the graph, we have the following observations:
The graph has a turning point at x = 2The graph changes the factor of its direction at x = -5This means that the graph has a multiplicity of 2 at x = 2 and a multiplicity of 3 at x = -5
So, we have:
f(x) = a(x + 5)³(x - 2)²
The curve is inverted,
This means that a < 0
Assume a = -1.
Then, we have:
f(x) = -(x + 5)³(x - 2)²
Hence, the equation of the polynomial graph is f(x) = -(x + 5)³(x - 2)²

p(x) = 16x -3600600 units417 unitsStep-by-step explanation:
The problem statement gives expressions and relations for revenue, cost, and profit. Substitute and simplify or solve, as appropriate.
__
(a)Given: r(x) = 20x; c(x) = 3600+4x; p(x) = r(x) -c(x)
The formula for p(x) is ...
p(x) = (20x) -(3600 +4x) . . . . substitute for r(x) and c(x)
p(x) = 16x -3600 . . . . . . . . simplify
__
(b-i)r(x) = 2·c(x) . . . . given relation for revenue and cost
20x = 2(3600 +4x) . . . . substitute for each
12x = 7200 . . . . . . . simplify and subtract 8x
x = 600 . . . . . . . divide by 12
Revenue is twice the cost when x = 600 units.
__
(b-ii)p(x) = 292 +1/3r(x) . . . . given relation for profit and revenue
16x -3600 = 292 +1/3(20x) . . . . . substitute for each
28/3x = 3892 . . . . . . . . add 3600 -20/3x
x = 417 . . . . . . . . multiply by 3/28
Profit is $292 more than 1/3 the revenue earned for 417 units.
