find R=x^2/y when
y=3.8x10^5
x=5.9x10^4

Answers

Answer 1

The value of the expression R = x^2/y when y = 3.8 x 10^5 and x = 5.9 x 10^4 is 9.2 x 10^3

How to evaluate the expression?

The expression is given as

R = x^2/y

Where

y = 3.8 x 10^5

x = 5.9 x 10^4

Substitute y = 3.8 x 10^5 and x = 5.9 x 10^4 in the equation R = x^2/y

So, we have

R = (5.9 x 10^4)^2/3.8 x 10^5

Evaluate the exponent

So, we have

R = 34.81 x 10^8/3.8 x 10^5

Evaluate the quotient

So, we have

R = 9.16052631579 x 10^3

Approximate the above expression

So, we have

R = 9.2 x 10^3

Hence, the value of the expression R = x^2/y when y = 3.8 x 10^5 and x = 5.9 x 10^4 is 9.2 x 10^3

Answers

Tt would take 15 minutes for there to be exactly 60 gallons in the hot tube.

What is proportion?

Proportion can be defined as the mathematical comparison of two numbers.

It is also known as an equation defining that the two given ratios are equivalent to each other.

From the information given, we have the following deductions;

There are 150 gallons of waterThe water drains at a rate of 6 gallons per minute

To determine the time taken for 60 gallons to be left in the hot tube, we have to subtract the number from the total number of gallons, we have;

= 150 - 60

Find the difference

= 90 gallons

Now,

If 6 gallons are drained in 1 minute

Then 90 gallons are drained in x minutes

cross multiply

x = 90/ 6

x = 15 minutes

Thus, it would take 15 minutes for there to be exactly 60 gallons in the hot tube.

Answers

The width of the rectangle as an exponential factor whose length is 2^(-1) m and Area is 2^(-4) m^2 is 2^(-3) meter.

As per the question statement, we are given a triangle whose length is 2^(-1) m and Area is 2^(-4) m^2 is 2^(-3) meter. We are supposed to find out the width of the rectangle as an exponential factor.

Before solving the question, we should know the formula for calculating the area of the rectangle

Area = Length * Width

Given Area = 2^(-4) m^2

Given Length =  2^(-1) m

Let Width = "x" m

2^(-4) =  2^(-1) * x

2^(-4)/2^(-1) = x

2^(-4+1) = x

2^(-3) = x

Hence width of the given rectangle as an exponential factor is

x = 2^(-3)  meter

Let α and β be the roots of the equation.

α ₊ β = ₋B/A

α×β = C/A

= a²/1

y = 3.0571 × 10⁻⁴

When we dived these two equations.

( x / y) = [ 2.058 × 10⁹ / 3.0571 × 10⁻⁴ ]

The significant digits in the number with the smaller number of significant digits should be used to determine the number of significant digits in a quotient where two numbers are divided by one another.

Answers

The inverse of the function will be:

if x is an integer, then f⁻¹ (x) = x - 1

for all other x , f⁻¹ (x) = x - 2

We are given the function as:

if x is an integer, then f (x) = x + 1

for all other x , f (x) = x + 2

Now, we need to find the inverse of the function.

We will do it in 2 parts.

First we will find the inverse of f (x) = x + 1 and then of f (x) = x + 2.

For f (x) = x + 1:

y = x + 1

y - 1 = x

x = y - 1

f⁻¹ (x) = x - 1

For f (x) = x + 2

y = x + 2

y - 2 = x

x = y - 2

f⁻¹ (x) = x - 2

Answers

The equation for the value of the painting of the years is y = 3000 + 330.4(x).

The estimated worth of the painting in 2030 is $7956.

In 2016, the worth of the painting is $3000.

In 2021, the worth of the painting is $4652.

The increase in worth in 5 years from 2016 to 2021 is:

= $4652 - $3000 = $1652

Hence, the increase in painting worth per year will be:

= $1652 / 5 = $330.4

Now, if x is in years and y is the worth of the painting in $.

Then, the equation for the worth of a painting is:

y = 3000 + 330.4(x)

From 2015 to 2030 the span is 15 years.

Then, the value of the painting in 2030.

So,

y = 3000 + 330.4(x)

The value of logarithmic expression 1/2 (logx4 + logx y) - 3 logx z as a single logarithm is (log4x^2y)^1/2/logx z^3

By considering the given  logarithmic expression

1/2 (logx4 + logx y) - 3 logx z

=1/2 (log4x^2y)-3 logx z

=(log4x^2y)^1/2- logx z^3

The logarithm is exponentiation's opposite function in mathematics. This means that the exponent to which a fixed number, base b, must be raised in order to produce a given number x, is represented by the logarithm of that number.

Based on the logarithm base, the logarithmic functions are broadly divided into two types. There are common and natural logarithms. Common logarithms are based on the number 10, while natural logarithms are based on the base "e."
