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\}

The temperature inside a certain industrial machine at time t seconds after startup, for 0 &lt; t &lt; 10, is given by h(t) = 42
frutty [35]

Answer:

t= \frac{125}{38} s

Step-by-step explanation:

We are given the temperature inside the machine from startup until 10 seconds later, the formula is:

h(t)= 42 \cdot t +1 - 4\cdot t +2  (degrees \, C)

We want to know at what time t the temperature inside the machine will be equal to 128 °C.

So we set:

h(t)=128

42\cdot t+1-4\cdot t+2=128

Now, we rearrange the equation to keep terms with t on the left hand side and terms without t on the right hand side

42\cdot t-4\cdot t=128-1-2

and we simplify:

(42-4)\cdot t= 128-2-1= 125

38 \cdot t = 125

now it's easy to solve for t:

t=\frac{125}{38}

And thus we arrive to the solution.

My question was;
UkoKoshka [18]

Answer:

84.

Step-by-step explanation:

96 / (7 + 5) + 19 * 4

Use order of operations (PEMDAS* ).

Perform the operation in the parentheses first:

= 96/12 + 19*4

Now the divide and multiplication:

= 8 + 76

and finally the add:

= 84.
