A man's shoe size is related to his foot length and can be modeled by the equation s = 1.7f - 7.2, where s is shoe size and f is foot length,in inches. What is the shoe size of a man whose foot measures 9 inches?

Answers

Answer 1

Answer:

On putting the value of given foot length in the linear equation, the shoe size of the man is 8.1.

What is linear equation?

A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation. The standard form of a linear equation in one variable is of the form Ax + B = 0.

Putting the value of f in the linear equation to calculate s.

$s = 1.7f - 7.2\ns = 1.7 * 9 - 7.2\ns = 15.3 - 7.2 = 8.1\n$

Given the function f ( x ) = − 1 x + 3 x 4 , f(x)=− x 1 + 4 3 x , find f ′ ( 4 ) . f ′ (4). Express your answer as a single fraction in simplest form.

Answers

Step-by-step explanation:

The question is not well written. Let us say the function given as expressed as;

f(x) = -1/x + 3/x⁴

f'(x) means we are to differentiate the function with respect to x;

Given f(x) = axⁿ

f'(x) = naxⁿ⁻¹

f(x) = -x⁻¹ + 3x⁻⁴

Applying the differentiation formula we will have;

f'(x) = -1(-x⁻²)+(-4)3x⁻⁴⁻¹

f'(x) = x⁻²-12x⁻⁵

Express as a fraction

f'(x) = 1/x²-12/x⁵

To get f'(4), we will have to substitute x = 4 into the resulting expression

f'(4) = 1/4²-12/4(5)

f'(4) = 1/16-12/20

f'(4) = 1/16-3/5

Find the LCM

f'(4) = (5-48)/80

f'(4) = -43/80

Note that the function used was assumed but the same method can be employed to any other functions.

How many days in 4 consecutive years

Answers

There are 365 days in a year.
So in 4 years, there are 365 × 4 = 1460 days.
However, every 4 years, there is also a "leap day." (an additional day in February of years divisible by 4 to balance the calendar)
After adding this day, we would have 1461 days in 4 consecutive years.

*Note: There are exceptions to when leap years happen, so on some 4 year periods there is no leap year. In that case, there could be just 1460.

In four consecutive years, there are 1461 days.

How did we get the value?

To determine the total number of days in four consecutive years, we need to consider whether those years are regular years or leap years.

A regular year has 365 days, while a leap year has 366 days. Leap years occur every four years, with some exceptions. The exceptions are years divisible by 100 but not divisible by 400, which are not leap years.

To calculate the number of days in fourconsecutive years, we first determine if any of the years in that span are leap years. If one or more of the years are leap years, we add an extra day for each leap year.

Let's consider the four-year period starting from the current year, 2023:

Year 2023: Regular year (365 days)

Year 2024: Leap year (366 days)

Year 2025: Regular year (365 days)

Year 2026: Regular year (365 days)

To calculate the total number of days in this four-year span, we add up the days for each year:

365 + 366 + 365 + 365 = 1461

Therefore, in four consecutive years, there are 1461 days.
