Please help; I have no idea how to solve this!! The temperature in degrees Celsius (C) can be converted to degrees Fahrenheit (F

) using the formula F(C)= 9/5C+k, where k is a constant. Find k, if to C=−40°C corresponds F=−40°F.

Answer:

32

Step-by-step explanation:

-40 = (9/5)(-40) + k

-40 = -72 + k

k = -40 + 72

k = 32

14. Compare the graph below to the function
Dahasolnce [82]

Answer:

Option (2)

Step-by-step explanation:

Parent function has been given as,

f(x) = \sqrt{x}

When translated by 3 units left,

f(x + 3) = \sqrt{(x+3)}

g(x) = \sqrt{(x+3)}

If the translated function is stretched vertically by a scale factor = k

New function will be,

g'(x) = k\sqrt{(x+3)}

Since a point (1, 4) passes lies on the transformed function.

g'(1) = k\sqrt{(1+3)}

4 = 2k

k = 2

Therefore, transformed function represents the translation by 3 units in the negative side of the x-axis and stretched vertically by 2 units.

Option (2) will be the answer.

Which function has a domain of all real numbers
Pachacha [2.7K]

Answer:

Most of the functions we have studied in Algebra I are defined for all real numbers. This domain is denoted . For example, the domain of f (x) = 2x + 5 is , because f (x) is defined for all real numbers x; that is, we can find f (x) for all real numbers x.
