The inverse of function is x= √1/3( y+5 )
what is Inverse of function?A function that reverses the effects of another function is called an inverse function. When y=f(x) and x=g(y), a function g is the inverse of a function f. . Applying f and then g is equivalent to doing nothing, in other words. This can be expressed as g(f(x))=x in terms of the relationship between f and g.
Given:
g(x) = 3x² - 5
To find the inverse of the function take g(x) = y
Then, solve for x
y= 3x² - 5
y + 5= 3x²
x² = 1/3( y+5 )
x= √1/3( y+5 )
Hence, the inverse of function is x= √1/3( y+5 ).

Marla is making 2 liters of cherry lemonade, 5 deciliter dog limeade and 2,500 milliliters strawberry lemonade for a party after the party was over she still a total of 1.3 liters of lemonade left. How many liters of lemonade were consumed during the party?
→Answer:
3.2 liters of lemonade were consumed during the party.
→Step-by-step explanation:
What we know
_____________________________________
Well there is 2,500 mL of strawberry lemonade
There are 2 liters of cherry
There are 5 deciliters of dog limeade
_____________________________________
So the 5 deciliters of dog limeade doesn't count because it is limeade, not lemonade.
The question is asking for the number of liters so we need to convert the 2,500 milliliters of lemonade to liters.
Which will be 2.5 liters of lemonade.
There are also 2 liters of cherry lemonade so 2.5 + 2 is 4.5.
So if 1.3 liters were left over doing 4.5 - 1.3 we get 3.2, meaning 3.2 liters of lemonade were consumed during the party.

So the value of the angle at the circumference would be 108/2 = 54
Is Lmn=OPQ? If so, name the congruence postulate that applies.
Answer:
Answer D
Step-by-step explanation:
Since 3 sides are congruent to 3 other sides, the two triangles are congruent due to the SSS postulate.
SSS stands for "side side side". It means that if you have three pairs of congruent corresponding sides, then the triangles are congruent. It's like saying every corresponding piece of two houses are the same, so the two houses overall must be identical.

if a savings account is opened with an initial deposit of $250, and interest is compounded monthly at 6.25% for 50 years, how much will the account be worth at the end of the 50-year period?
Answer:
$-9125
Step-by-step explanation:
6.25÷100 = 0.0625 50×12=600
0.0625×250= $15.625
6.25%=$15.625
15.625×600= $9375
$250-$9375= -9125
The account be worth at the end of the 50-year period will be 9125 dollar.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
Given that savings account is opened with an initial deposit of $250, and interest is compounded monthly at 6.25% for 50 years.
The rate is 6.25÷100 = 0.0625
Therefore, 50×12=600
0.0625×250= $15.625
Since we know that 6.25%=$15.625
15.625×600= $9375
Thus we get;
$250-$9375 = -9125
Hence, the account be worth at the end of the 50-year period will be 9125 dollar.

Study the following figure, where two concentric circles share center C.
Segment AB is a diameter of the larger circle.
Segment AB intersects a chord of the smaller circle, PQ, at a right angle at point Z.
Segment AB intersects a chord of the larger circle, MN, at a right angle at point 0.
If MO=7x-4, and NO=6x, what is the length of MN
Answer:
Length of MN = 48 units
Step-by-step explanation:
AB is the diameter of the larger circle which is perpendicular to both the chords PQ (chord of the smaller circle) and MN(chord of the larger circle).
Theorem says,
"Radius or a diameter of a circle which is perpendicular to the chord divides the chord in two equal parts."
Therefore, MO ≅ ON
m(MO) = m(ON)
7x - 4 = 6x
7x - 6x = 4
x = 4
m(MN) = m(MO) + m(ON)
= (7x - 4) + (6x)
= 13x - 4
= (13 × 4) - 4
= 52 - 4
= 48
Length of chord MN will be 48 units.

As supply rises, prices generally decrease.
As demand decreases, costs generally increase.
As supply decreases, prices increase
The average rate of change describes
As demand rises, the price of the product decreases.
te increases.
Answer:
Statements 1,3 and 4 are correct
Step-by-step explanation:
We want to select the three correct statements as related to demand and supply.
Statement 1 is correct
An increased supply would lead to saturation of the market with the product for normal goods. The saturation of the market will surely make the price of the goods in the market decrease
Statement 2 is incorrect
A decrease in demand should drive down the prices of commodities for normal goods
Statement 3 is correct
A decrease in supply means there are less goods in the market. This makes consumers want to fight more to get their share in the market which thus forces up price of these goods
Statement 4 is correct
An increase in demand would make suppliers increase the price they place on their commodities.
A rectangular plot measures 20 ft. By 30ft. A 3ft wide side walk surrounds it. Find the area of the side walk
Answer:
336 feet²
Step-by-step explanation:
If we have a rectangle that is 30 by 20 feet, that means the area of that rectangle would be 20 × 30 feet squared, which is 600 ft².
If there is a 3 feet sidewalk surrounding it, that means that the end of the sidewalk will extend 3 feet extra around each side of plot. Since there are two ends to one side, that means an extra six feet is added on to each dimension. Therefore, 36 × 26 are the dimensions of the sidewalk+plot. 36 × 26 = 936 ft².
To find the area of the sidewalk itself, we subtract 600 ft² from 936 ft². This gets us with 336 ft².

Answer:
C. (6, 5) and (3, -4)
Step-by-step explanation:
Given the equation 3x - y = 13, we need to figure out which points satisfy it. In order for an ordered pair to satisfy an equation, when we plug the x-coordinate in for x and the y-coordinate in for y, the equation should hold true.
Let's try with (6, 5):
3x - y = 13
3 * 6 - 5 =? 13
18 - 5 =? 13
13 = 13
Since this is true, we know that (6, 5) is indeed a solution.
Now let's try with (3, -4):
3x - y = 13
3 * (3) - (-4) =? 13
9 + 4 =?13
13 = 13
Again, since this is true, then (3, -4) must be a solution.
Thus, the answer is C.

Answer:
x = - 3, x = 0.5
Step-by-step explanation:
Given
10x² + 5x - 15 = - 12 + 8x² ( subtract 8x² from both sides )
2x² + 5x - 15 = - 12 ( add 12 to both sides )
2x² + 5x - 3 = 0 ← in standard form
(x + 3)(2x - 1) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 3 = 0 ⇒ x = - 3
2x - 1 = 0 ⇒ 2x = 1 ⇒ x = 0.5

An intelligent trader travels from 1 place to another carrying 3 sacks having
30 coconuts each. No sack can hold more than 30 coconuts. On the way
he passes through 30 checkpoints and on each checkpoint he has to give 1
coconut for each sack he is carrying. How many coconuts are left in the
end? *
Answer:
none
Step-by-step explanation:
the man is carrying 3 sacks
each has 30 coconuts
so at total he has 90 coconuts: 30*3= 90
he passe through 30 checkpoints
ha has to give 1 coconut for each sack
so he gives 3 coconuts each time: 3*1=3
there are 30 ckeckpoints so : 3*30= 90
he has spent all the coconuts unless he has a trick
He starts with 3 sacks with 30 in each sack.
He has to give 1 coconut per sack away. So at first he gives 3 coconuts away.
The first 10 checkpoints he gives away 30 coconuts, so he is left with 2 sacks.
Now he has to give 2 coconuts away. 30/2 = 15, so the next 15 checkpoints he ends up giving away another full sack, so he is left with 1 full sack of 30 coconuts and he has 5 checkpoints left.
Giving away 1 coconut at those checkpoints, he would have 25 left
