If the domain of f(n) = -4n - 3 is (-1, 1/4,4}, what is the range?
ahrayia [7]

Answer:

Range= \{1,-4,-19\}

Step-by-step explanation:

Given

f(n) = -4n - 3

n = \{-1,1/4,4\} --- domain

Required

Determine the range

To do this, we simply substitute the values of n in the given expression

So, we have:

n = -1

f(-1) = -4 * -1 - 3 =4 - 3 = 1

n = 1/4

f(-1) = -4 * 1/4 - 3 =-1 - 3 = -4

n=4

f(-1) = -4 * 4 - 3 =-16 - 3 = -19

Hence, the range is:

Range= \{1,-4,-19\}

A refrigeration system at your company uses temperature sensors fixed to read Celsius (°C) values, but the system operators in y
Anton [14]

Answer:

14°F

Step-by-step explanation:

We are given that,

The label for the high temperature is -10°C.

It is required to label the alarm in Fahrenheit (°F).

As we know,

(1°C × \frac{9}{5}) + 32 = 33.8°F

Thus, for -10°C, we have,

(-10°C × \frac{9}{5}) + 32 = -18 + 32 = 14°F

Hence, the Fahrenheit value on the label will be 14°F.

al dividir A entre 23 se obtuvo 247 de cociente y el residuo fue el maximo. hallar A a)5242 b)5436 c)5703 d)5332 solo esas 4 alt
yuradex [85]

Aplicando la división, hay que el valor de A es dado por:

c) 5703

Una división es representada por:

\frac{a}{b} = c + \frac{r}{b}

En que:

  • c es el cociente.
  • r es el residuo.

En este problema, b = 23, y también:

  • Cociente de 247, o sea, c = 247.
  • Residuo maximo, que es 22, o sea, r = 22.

\frac{a}{b} = c + \frac{r}{b}

\frac{A}{23} = 247 + \frac{22}{23}

A = 23(247) + 22 = 5703

El valor de A es dado por:

c) 5703
