State if the given functions are inverses. f(x) = 1/x + 3 g(x) = 4/x + 2

Answers

Answer 1

Answer:

  they are not inverses

Step-by-step explanation:

f(1) = 1/1 +3 = 1 +3 = 4

g(4) = 4/4 +2 = 1 +2 = 3 ≠ 1

If the functions were inverses, we would have g(f(1)) = 1, which we do not.

The given functions  are not inverses.

_____

The same would be true if your functions were

  f(x) = 1/(x+3) and g(x) = 4/(x+2)

  f(1) = 1/(1+3) = 1/4

  g(1/4) = 4/(1/4 +2) = 4/(9/4) = 16/9 ≠ 1

Three girls-- Kali, Annie, and Xiaoling -- go on a trip with their youth orchestra. The three girls share the cost of the hotel. The bill comes to $295.48. It includes $13.25 for some food that Annie orders and $14.00 for cleaning Xiaoling's uniform. What is the dollar amount of each girl's share of the hotel bill?

Answers

Answer:

About $107.57

Step-by-step explanation:

if you add up the bill cost and the 13.25 for the food and 14.00 for cleaning Xialing's uniform its $322.73 divide that between the 3 girls and you get about 107.57

Each girl would pay Kali = $89.41

Annie = $102.66

Xiaoling  = $103.41

What is Unitary Method?

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

Foe example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Total bill amount = $295.48

Now, the amount excluding the amount of food ordered by Annie

= 295.48 - 13.25

= $282.23

and, the amount excluding Cleaning amount

= 282. 23 - 14

= $268.23

So, Each Girl would pay

Kali = $ 268.23 / 3 = $89.41

Annie = 89.41 + 13.25 = $102.66

Xiaoling = 89.41 + 14 = $103.41

Step-by-step explanation:

Step 1: Write out equation

x² + 8x - 10 = 0

Step 2: Add 10 to both sides

x² + 8x = 10

Step 3: Complete the Square

x² + 8x + 16 = 10 + 16

(x + 4)² = 26

Step 4: Square root both sides

x + 4 = ±√26

Step 5: Subtract 4 on both sides

x = -4 ± √26

There 8 × 10⁴ would be 10⁹ times as large as 4 × 10⁻⁵ which is determined by the division operation.

What is the division operation?

In mathematics, divides left-hand operands into right-hand operands in the division operation. The primary purpose of the division is to generate equal groupings or to determine how many people are in each category after a fair distribution.

For example 4/2 = 2

We have to determine 8 × 10⁴ is how many times as large as 4 × 10⁻⁵

Apply the division operation to get

⇒ 8 × 10⁴ ÷  4 × 10⁻⁵

⇒ (8 × 10⁴) /  (4 × 10⁻⁵)

Reduce the term of the numerator

⇒ ( 10⁴) / (10⁻⁵)

⇒ ( 10⁴) × (10⁵)

⇒ ( 10⁴⁺⁵)

⇒ 10⁹

Hence, there 8 × 10⁴ would be 10⁹ times as large as 4 × 10⁻⁵ which is determined by the division operation.

Savannah can run 1/2 mile in 300 seconds. What is
Savannah's unit rate?
10 mile per minute
2 1/2 mile per minutes
2/5 mile per minutes
1/10 mile per minute

Answers

1/10 miles per minute because it took her 5min to run 1/2

The required unit rate of the Savannah run is given as 1/10 mile per minute. Option D is correct.

What is the unit rate?

A unit rate is a rate in which the second term is 1. In other words, a unit rate is a rate that compares two quantities, with the second quantity being expressed as 1. Unit rates are often used to express a rate per unit of measurements, such as price per item, speed per hour, or cost per pound.

here,
As given in the question Savannah can run 1/2 mile in 300 seconds to evaluate the unit rate we must convert the time given second in minutes by dividing it by 60,
300 seconds = 300/60 = 5 minutes

Now,

Unit rate = 1/2 mile: 5 minutes
Unite rate = 1/10 mile per minute

Thus, the required unit rate of the Savannah run is given as 1/10 mile per minute. Option D is correct.

This sequence will have a pattern. Our goal is to try and find this pattern.

Our first two numbers are -45 and 9. The first relationship between these numbers that pops into my mind is 5. [tex]9 \cdot 5 = 45[/tex]. However, we go from -45 to 9. This means we have to divide by -5. [tex]-45 \div -5 = 9[/tex]

Let's check this actually is what the sequence is. It would be true if [tex]9 \div -5 = -1.8[/tex].

[tex]9 \div -5 = -1.8[/tex]

So -5 is the divisor.

To find the next term in the sequence, we divide -1.8 by -5.
