or f inverse of the inverse of 6.022 is equal to what?
And f^-1(-10) + f(6) =
Or f inverse of (-10) + f of (6) is equal to what?
Need help please
Answers
[tex]f^{-1}[/tex](f(6.022)) is 6.022 and [tex]f^{-1}[/tex](-10) + f(6) is -4
The general evaluation of function is
[tex]f^{-1}[/tex](f(x)) = x
Here we have to find [tex]f^{-1}[/tex](f(6.022))
Therefore [tex]f^{-1}[/tex](f(6.022)) = 6.022
Now we have to find the value of [tex]f^{-1}[/tex](-10) + f(6)
Form the table of values, we have
[tex]f^{-1}[/tex](-10) = -6 and f(6) = -10
So we have
[tex]f^{-1}[/tex](-10) + f(6) = 6 + (-10)
= 6 -10
= -4
Therefore [tex]f^{-10}[/tex] (-10)+ f(6) = -4

A skier is trying to decide whether or not to buy a season ski pass. A daily pass costs $70. A season ski pass cost$450. The skier would have to rent skis with either pass $30 per day. How many days would the skier have to go skiing in order to make the season pass less expensive than the daily basis
Answers
The skier have to go for 7 days skiing in order to make the season pass less expensive than the daily basis.
Cost of daily pass = $70
Cost of season ski pass = $450
Let the cost of skiing per day = 'x'
Now we will equate the season pass plus ski rentals to daily skiing plus ski rentals :
450 + 30x = 70x + 30x
We have 30x on both sides, so those can cancel out easily :
Then we get,
450 = 70x
Dividing both sides by 70 :
x = 6.42
We can't pay for a partial day, so the skier will have to ski for at least 7 days to make the season pass cheaper than getting daily passes.

x + x + 2 + x + 4 = y is the basic formula for even integer equations like this, and in this case y= 156

After using 25 square block, a quilt has been prepared by Wei-Min that has an area of 100 square inches. The length of each side of a block is 2 inches by calculating using concept of mensuration.
As per the question statement, Wei-Min makes a square quilt that has an area of 100 square inches and has got 25 square blocks, each the same size. We are supposed to find the length of each side of a block.
Using concept of mensuration,
Area of square quilt = 100 square inches
Number of block used = 25 square blocks
Therefore, area of each block = 100/25 = 4 square inches
As the block is a square, so each side will be equal in length.
Let's assume each side of square be "x" inches
Therefore x^2 = 4
or x = √4
or x = 2 inches

Ganesh spends 60% of his income every month and saves Rs 11120 in a month. Find his monthly income and expenditure.
Answers
Monthly income and expenditure of Ganesh will be-16680
Let Ganesh's monthly income be x
The problem can be solved using linear equation
The amount of 60% of his salary is spent which can be written as 60% of x or 0.6x
The amount of money saved by Ganesh = total salary - amount spent
= x - 0.6x
= 0.4x
The amount of savings made by Ganesh as per the question = 11120
Lets equate both the equation
0.4x = 11120
x = (11120 × 100)/ 40
x = 27800
Hence, Ganesh's monthly salary comes out to be 27800
Ganesh's monthly expenditure = 0.6 x= 0.6 × 27800 =16680

What is a Linear Function?A linear function can be described as a function whose graph is represented as a straight line graph on a coordinate plane with all its points plotted on the graph.
A linear function is modelled by the equation which is expressed in slope-intercept form as .f(x) = mx + b.
The "m" in the equation represents the rate of change of the function, which can also be called the slope of the graph while "b" represents the y-intercept where the line intercepts or crosses the y-axis.
What is the Rate of Change of a Function?The rate of change of a linear function = the slope = change in y / change in x.
Use two pairs of values from the table to find the rate of change, say, (2, 240) and (5, 600):
Rate of change (m) = (600 - 240) / (5 - 2)

Answers
The scale is equal to 1:500.
The ratio between a distance on a map and its corresponding distance on the ground is referred to as the "map scale."
if 1 cm on the map corresponds to 100 cm on actual ground then the scale of the map is given by the ration 1:100.
Scale of map is widely used in cartography and constructions.
The given condition states that 3 cm to 15 m.
We know that 1 cm =100 meters
Hence 15 meters = 15 × 100 cm =1500 cm
Therefore length on map = 1 cm
Length on ground = 1500 cm
Scale = distance on map : distance on ground
or, Scale = 3 : 1500

However, bar models just make it simpler for students to determine which calculation needs to be made in order to answer the problem. They do not perform the calculations for the student.Let us consider that each had x marbles. Now Brooke gave away 20 marbles and Samuel gave away 44 marbles :
∴ x - 20 = 3 (x - 44)

It is given that farmer wants to do fencing of 246 feet which means all the boundary will be covered which is given by
[tex]L+L+w+w+w=246\\2L+3w=246\\2L=246-3w\\\\L=\frac{246}{2} -\frac{3w}{2} \\\\L=123-\frac{3w}{2}[/tex] ...(2)
Putting the value of "L" in equation (1) , we get
[tex]A=({123-\frac{3w}{2}}) \times w\\\\A=123w-\frac{3w^2}{2}[/tex] ....(3)
Now , we are asked to find the maximum area then , put
[tex]\frac{dA}{dw}=0[/tex]
[tex]123-\frac{6w}{2} =0\\123-3w=0\\123=3w\\w=41[/tex]
Putting w = 41 in equation (3) , we will get the maximum area
[tex]A=123(41)-\frac{3(41)^2}{2} \\\\A=5043-2521.5\\\\A=2521.5[/tex]
Putting w = 41 in equation (2) , we will get the length
[tex]L=123-\frac{3(41)}{2} \\L=123-61.5\\L=61.5feet[/tex]
Hence , the dimensions will be 61.5 feet by 41 feet .
