please help me!!!!!!! ​

Step-by-step explanation:

the inverse function simply calculate the original x it of a given y. so, we need to transform the original function to calculate x instead of y.

and then, at the end to make it a formally correct function definition, we rename x to y and y to x.

y = x + 3

x = y - 3

=> to make it a formally correct function definition

y = x - 3 = h(x)

The rate of inflation between year 1 and year 2, based on the CPI, is  c. 33.33%.

The Consumer Price Index (CPI) allows us to calculate inflation. To find the inflation across these years, use the formula:

= (CPI₂ - CPI₁) / CPI₁ x 100%

Solving gives us:

= (200 - 150) / 150 x 100%

= 33.3%

In conclusion, the inflation is 33.3%.

Answer:

  √40 ≈ 6 4/13 ≈ 6.31

Step-by-step explanation:

The estimate by linear approximation starts with the recognition that ...

  40 = 36 +4 = 6² +4

and the difference from 36 to the next square, 7² = 49 is 49-36 = 13.

The linear approximation to √40 is ...

  √40 ≈ 6 4/13 ≈ 6.31

__

There are various methods for improving this approximation. Perhaps the fastest improvement is obtained using the "Babylonian method." The next iteration is the average of this value and 40 divided by this value.

  (82/13 +40/(82/13))/2 = 6 173/533 ≈ 6.3246 . . . . accurate to 4 decimal places

_____

Additional comment

When you write the value in terms of a square and a remainder:

  n = s² +r

then the above linear approximation of √n can be written as ...

  √n ≈ s +r/(2s+1)

Using the idea that a square root can always be represented by a continued fraction, we can continue the fraction one more iteration to give a slightly better approximation:

  √n ≈ s +r(2s+1)/(2s(2s+1) +r)

For the case at hand, this gives √40 ≈ 6+52/160 = 6 13/40 = 6.325, accurate to 3 decimal places. Additional iterations using the continued fraction idea can be had using ...

  n'' = s + r/(s +n') . . . . . where n' is an approximation of the root and n'' is a better approximation. This does not converge as fast as the Babylonian method, but may be easier to calculate on some calculators.

Answer:

[tex]y = - \frac{4}{5} x + \frac{6}{5} [/tex]

Step-by-step explanation:

First subtract 4x on both sides in order to get -5y alone. Now you have -5y = 4x + 6 (since neither 6 nor 4x are like terms). Now divide -5 on both sides in order to get rid of it, so we can get y by its self. Now you have y = -4/5 x + 6/5

Answer:

Step-by-step explanation:

you just gotta add all the side-lengths together and consider each grid square as 10 instead of 1.

so 70 + 40 + 20 + 60 + 20 + 40 i believe.

this all equals 250.

ask your teacher if its a type, because there's no 250 on there. grab a calculator or something as proof.

The given curve has equation

r(θ) = 9 + 8 cos(θ)

and its derivative is

dr/dθ = -8 sin(θ)

When θ = π/3, we have r (π/3) = 13, and dr/dθ (π/3) = -4√3.

Differentiate these with respect to θ :

dy/dθ = dr/dθ sin(θ) + r(θ) cos(θ)

dx/dθ = dr/dθ cos(θ) - r(θ) sin(θ)

In polar coordinates, we have

y(θ) = r(θ) sin(θ)

x(θ) = r(θ) cos(θ)

and when θ = π/3, we have y (π/3) = 13√3/2 and x (π/3) = 13/2.

The slope of the tangent line to the curve is dy/dx. By the chain rule,

dy/dx = dy/dθ • dθ/dx = (dy/dθ) / (dx/dθ)

dy/dx = (dr/dθ sin(θ) + r(θ) cos(θ)) / (dr/dθ cos(θ) - r(θ) sin(θ))

When θ = π/3, the slope is

dy/dx = (-4√3 sin(π/3) + 13 cos(π/3)) / (-4√3 cos(π/3) - 13 sin(π/3))

dy/dx = (-4√3 (√3/2) + 13 (1/2)) / (-4√3 (1/2) - 13 (√3/2))

dy/dx = - 1/(17√3)

So, the tangent line has slope -1/(17√3) and passes through (13/2, 13√3/2). Using the point-slope formula, its equation is

y - 13√3/2 = -1/(17√3) (x - 13/2)

y = -(x - 338)/(17√3)

Answer:

15 Hours

Step-by-step explanation:

So you have one block, and your friend has two.

We know that you work for 3 hours, this means that your only block must represent 3 hours.

And all the blocks represent the same amount of time, then each one of the two blocks of your friend also represents 3 hours.

Then in total, he tutored for 3 hours + 3 hours = 6 hours.

Therefore, you still have only one block, but now your friend has 5.

Using the same reasoning as above, we can conclude that each block represents 3 hours, and your friend has 5 of them, this means that he tutored for:

5*3 hours = 15 hours

Answer:

After depositing rs. 1500 ratan got rs. 7500 in his bank account. When he withdrew 1/3 of 7500, he withdrew rs. 2500 from his bank account.. so left amount in bank is 7500-2500= 5000 rupees

Answer :

square of 5 is 25 .

The equation of the line is represented in table number 2. Then the correct option is B.

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

From the graph, the y-intercept is 5. Then the equation is given as,

y = mx + 5

From the graph, the equation passes through (-4, -3). Then we have

- 3 = (-4)m + 5

- 8 = - 4m

m = 2

Then the equation is given as,

y = 2x + 5

The equation of the line is represented in table number 2. Then the correct option is B.

The average rate of growth of the ice can be found by dividing the thickness by the number of days of growth

The growth rate of the ice over the 8 days is 0.375 inches/day
