Answer:

f^-1 is P and f^-1(x) = 3x+4

Step-by-step explanation:

I did the work in my notebook but pretty much to find the inverse of [tex]\frac{x-4}{3\\}[/tex] you gotta do an equation and yeh its pretty simple.

The solution is , f^-1 is P and f^-1(x) = 3x+4.

An expression is any mathematical statement which consists of numbers, variables and an arithmetic operation between them. In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.

here, we have,

from the given figure, we get,

The line r represents f(x)=x-4/3.

so, we get,

f^-1 is P

let, y = f(x)

and, f^-1(y)=x

i.e. y = x-4/3.

3y=x-4

x=3y+4

so, f^-1(y) = 3y+4.

and f^-1(x) = 3x+4.

Answer:

slope = -3

x-intercept = (4/3,0) = (1.33,0)

y-intercept = (0,4)

f(-1) = 7

Step-by-step explanation:

Take 2 known points

i.e (0,4) and (1,1) from the graph

slope = (1-4)/(1-0) = -3

now we have

linear equation

y = mx+c

we have (0,4)

4 = -3 * 0 + C

C =4

so the equation of line is

y = -3x + 4

now

f(-1) = -3 * -1 +4 = 3+4 =7

for x intercept, put y = 0

o = -3x + 4

x = -4/-3 = 4/3

for y intercept, x = 0

y = -3 * 0 + 4 = 0+4 = 4

The answer is -70.22

Step-by-step explanation:

Answer:

-70.20

Step-by-step explanation:

Answer:

192

Step-by-step explanation:

There are 2 ways of solving for <4

The first is just to add the 2 angles not connected to <4

<4 = 51 + 51 = 102

The second is to find <2 and take that away from 180

<2 + 51 + 51 = 180

<2 = 180 - 102

<2 = 78

<4 + <2 = 180   (They are supplementary

<4 = 180 - 78

<4 = 102

Answer:

The cost of using 18 HCF = $40.39

Step-by-step explanation:

A linear function is one that has a constant rate of change for all the values within the distribution. For a linear function, there is a constant, and that constant is known as the slope or gradient of the linear function.

Let us first calculate this constant (slope).

Let:

X₁ = 14 HCF, Y₁ = $33.79, X₂ = 27 HCF, Y₂ = $55.24, m = slope

[tex]m = \frac{Y_2-Y_1}{X_2 - X_1} \\m = \frac{55.24 - 33.79}{27-14} \\m = \frac{21.45}{13} \\m = 1.65[/tex]

at any two points on the linear function, the rate of change of the cost to HCF = 1.65

Now, Let X₃ = 18 HCF, Y₃ = cost for using 18 HCF

[tex]m = \frac{Y_3 - Y_1}{X_3-X_1} \\where\ m= 1.65\\1.65 = \frac{Y_3-33.79}{18-14}\\1.65 = \frac{Y_3 - 33.79}{4} \\6.6 = Y_3 - 33.79\\Y_3 =6.6+33.79\\Y_3 = 40.39[/tex]

Therefore, the cost of using 18 HCF = $40.39

N:B X₂ and Y₂ can also be used with X₃ and Y₃ to find Y₃. You can try it out, you should get the same result

Answer:

Answer:

the correct answer is isosceles

Answer:

When two shapes are similar, their corresponding angles will be the same.  The angles are the same because the shape is still the same.  You can tell from the order of the similarity statement which angles match up.  In the example, angles A and D are the same (both letters are in written first), angles B and E are the same (both letters are written in the middle), and C and F are the same

Step-by-step explanation:

Similar triangles can be different sizes, so the lengths of the corresponding sides are not necessarily the same, but they are proportional.  This means that the ratios of the corresponding sides are equal.

Answer:

Step-by-step explanation:

Even though no answer choices are given, the main benefit of this is that by choosing a randomly from a population it allows every single individual to have the same chance of getting chosen and observed. This randomness allows for that sample group to much more accurately represent the entire population that is being observed without having to conduct additional research. Therefore, becoming extremely useful in such studies.

A sample is a  group that is taken out of the population to be tested.

A random sampling occurs when subjects are being selected for a study  

The benefit of using random sampling is that each subject in the population is equally likely to be selected and the resulting sample is likely representative of the population.

Random sampling allows for unbiased estimates to be created, but at the cost of efficiency within the research process

Answer: Jane

Step-by-step explanation: Her pay is going up by the same amount, 12, each time.

Answer:

Matt's pay is not linear

Jane's pay is linear, and it is $12/hour

Step-by-step explanation:

Matt's Earnings:

As the time goes from 1 hour to 2 hours, the difference in hours is 1, the difference in pay is $8. From 2 hours to 3 hours, the difference in hours is again 1, but the difference in pay is $11. Since equal changes in x do not produce equal changes in y, Matt's earnings are not linear.

Jane's Earning:

As the time goes from 1 hour to 2 hours, the difference in hours is 1, the difference in pay is $12. From 2 hours to 3 hours, the difference in hours is again 1, and the difference in pay is again $12. Since equal changes in x produce equal changes in y, Jane's earnings are linear.

Answer:

dh/dt = 8/9π

Step-by-step explanation:

Given that

Volume of A cone = 1/3πr²h.

Assuming v is the volume of the tank, then dv/dt = 2 m³/min

Assuming h is the height of the water we're looking for dh/dt

To start, we need to find a relationship between dh/dt and dv/dt

We then write v as a function of h, instead of having it as h & r, and then by using similar triangles, we notice that

r/h = 2/4, essentially, r = h/2.

Now, we substitute for this r, in the formula for volume

V = 1/3πr²h

V = 1/3 * π * (h/2)² * h

V = 1/3 * π * h³/4

If we differentiate v, wrt t, we have

dv/dt = π/12 * 3h² * dh/dt

dv/dt = π/4 * h² * dh/dt

Remember that h = 3, so, substitute for h

2 = π/4 * 9 * dh/dt

8/π = 9 * dh/dt

dh/dt = 8/9π

3/2= axis of symmetry

Then plug that in to find the vertex/maximum or minimum

3/2^2-3(3/2)+5

9/4-9/2+5

You can only add fractions with like denominators multiply 9/2(2/2) and 5(4/4)

So, 9/4-18/4+20/4

9/4-18/4= -9/4+20/4= 11/4
