Find the inverse of the given function. (pictured below)

Mathematics
1 answer:
zavuch27 [327]3 years ago
4 0

Answer:

4

3

0

Step-by-step explanation:

f(x) = y = -1/2 × sqrt(x+3)

2y = -sqrt(x+3)

4y² = x + 3

x = 4y² - 3

now renaming this, so that the normal symbols and names are used for this function definition, so that the input variable is called "x" :

f-1(x) = 4x² - 3

basically, just by itself, this function would be defined for all possible real values of x.

but because it is the inverse of the original function, which generates only values of y<=0, then for the inverse function that same range applies for its input variable x

x<=0

I started this and got distracted and never finished and it timed out. Focus Dean.

It's not the best graph; I assume the origin is the apparent origin and the y axis numbers go with the line above them.

This graph is M(V), M(V) is mass in kg of bucket with water volume V in liters

a) the mass of an empty bucket

That's the y intercept, M(0), eyeballing it around .7 kg

Answer: .7 kg

b) the mass of the bucket containing 1 liter of liquid

That's M(1), looks like 1.3 or so

Answer: 1.3 kg

c) the mass of one liter of liquid

That's the difference, M(1)-M(0), about .6 kg. We can get a better estimate from a longer slope, say (.5,1) to (3,3), (3-1)/(3-.5) = .8 kg.

Answer : 0.8 kg

d) the volume of the liquid in the bucket, if the total mass of bucket with the liquid is 3 kg.

Solve M(V)=3

That has a solution from the graph V=3.

Answer: 3 liters

Write the expression 10 + 25 in a different way,
Harman [31]
25+10 is the answer

In the Commutative law of addition, it says that a+b and b+a are the same which makes ab and ba equal to one another.

To prove just add 10+25 and 25+10to show that both results in 35 (aka the same answer)

Which describes a financial product offered by insurance companies that, in return for an investment, provides fixed payments ea
adelina 88 [10]

Answer:

Period annuity is the answer.

Step-by-step explanation:

Period annuity or fixed period describes a financial product offered by insurance companies that, in return for an investment, provides fixed payments each month for a certain amount of time.

A period annuity pays income to the person for a specified period of time like ten years. The payments depend on the amount paid into the annuity and the length of the payout period.

Whereas, the lifetime annuity provides income for the remaining life of the person.

Therefore, period annuity or fixed period annuity is the answer.
