Answer 1
Answer:

Answer:

F = (9C + 32)/(5)

Step-by-step explanation:

Given

C = ((5F - 32))/(9)

Required

Determine the inverse function

C = ((5F - 32))/(9)

Make F the subject of formula:

Multiply through by 9

9C = 5F - 32

Add 32 to both sides

9C + 32= 5F

Divide through by 5

(9C + 32)/(5)= F

F = (9C + 32)/(5)

Answer 2
Answer:

The inverse function is °F = (9/5 * °C) + 32.

To determine this inverse function, we first need to understand that it's the reverse conversion from Celsius to Fahrenheit. In the original conversion from Fahrenheit to Celsius, we subtracted 32 from the Fahrenheit temperature and then divided the result by 9/5 (or 1.8).

To find the inverse, we need to do the opposite operations in reverse order. First, we need to undo the division by 1.8, which is equivalent to multiplying by 5/9. Then, we need to undo the subtraction of 32 by adding 32 to the result.

This process is different from determining previous inverses because it involves reversing the operations in the opposite order and with different constants (5/9 and 32) compared to the original function.

The F and °C variables need to be switched in the inverse function because we are now going from Celsius to Fahrenheit, and the relationship between these temperature scales requires different mathematical operations.

Switching them makes sense because it aligns with the real-world relationship between the two temperature scales and ensures that the inverse function correctly converts from Celsius to Fahrenheit

The planet Mars has a radius of 3400 km. What is the volume of Mars?Write your answer in scientific notation to three decimal places.

Answers

Answer:

1.646×10¹¹ km³.

Step-by-step explanation:

From the question given, we obtained the following information:

Radius (r) = 3400 km

Volume (V) =.?

The shape of a planet is spherical in nature. Thus, we shall apply the formula for calculating the volume of a sphere to obtain the volume of Planet Mar as illustrated below:

Radius (r) = 3400 km

Pi (π) = 3.14

Volume (V) =.?

Volume of a sphere = 4/3 πr³

V = 4/3 × 3.14 × (3400)³

V = 4/3 × 3.14 × 3.9304×10¹⁰

V = 1.646×10¹¹ km³

From the calculations made above, the volume of Planet Mar is 1.646×10¹¹ km³

Question 8 of 10If f(x) = 5x – 2 and g(x) = 2x + 1, find (f+g)(x).

Answers

The solution is : If f(x) = 5x – 2 and g(x) = 2x + 1, then the value of  (f+g)(x) is : 7x-1.

What is function?

Function, in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable.

here, we have,

given that,

If f(x) = 5x – 2 and g(x) = 2x + 1,

now, we have to find (f+g)(x).

so, we have,

f(x) = 5x – 2

and g(x) = 2x + 1

now,

(f+g)(x)

=f(x)+g(x)

=5x-2+(2x+1)

=5x-2+2x+1

=7x-1

Hence, The solution is : If f(x) = 5x – 2 and g(x) = 2x + 1, then the value of  (f+g)(x) is : 7x-1.

-3 = 15+4y round to nearst tenth

Answers

Answer:

y = - 4.5

Step-by-step explanation:

given the equation

- 3 = 15 + 4y ( subtract 15 from both sides )

- 3 - 15 = 15 - 15 + 4y ( simplify both sides )

- 18 = 4y ( divide both sides by 4 )

(-18)/(4) = (4)/(4) y , that is

- 4.5 = y

Savanna is playing a game with her friends. She tells them to each pick a number, and then she directs them to: 1. Multiply their number by 4 2. Subtract 6 from that number 3. Divide that number by 2. Once they do that, they each tell Savanna their number a. Arturo says his "new" number is -15. What number did Arturo start with?

Answers

Answer:

x  = - 6

Step-by-step explanation:

Let  x  b number, according to instructions´ we must

1.-Multiply  by  4

2.-Subtract  6

3.-Divide by 2

4.-Arturo says his new number  - 15

4,.Which one was the original number   ??

The maths expression for that  is :

(4*x - 6 ) / 2  =  -  15

we solve for x

4x  -  6  = - 30

4x   =  - 24

x  = - 6

Final answer:

To find Arturo's starting number, reverse the given steps: divide by 2, add 6, then multiply by 4.

Explanation:

To find Arturo's starting number, we need to reverse the steps Savanna provided. Let's go through the steps backwards:

  1. Arturo's number after dividing by 2 is -15 * 2 = -30.
  2. Arturo's number after adding 6 is -30 + 6 = -24.
  3. Arturo's number after multiplying by 4 is -24 / 4 = -6.

Therefore, Arturo started with the number -6.
