What is 17+6-6+6 divided by 6 + 17.

alina1380 [7]

Answer:

$\boxed{\bold{1}}$

Using Pedmas rule:

$\dashrightarrow \sf \dfrac{17+6-6+6}{6+17}$

subtract: 6-6 = 0

$\dashrightarrow \sf \dfrac{17+6}{23}$

simplify the following

$\dashrightarrow \sf \dfrac{23}{23}$

the numerator and denominator cancels out

$\dashrightarrow \sf 1$

A cup of coffee is cooling down such that its temperature is decreasing at a constant rate of 8% per minute. Let’s say the coffe

KengaRu [80]

Answer:

Temperature after 1 minute = 184 ° F

Step-by-step explanation:

starting temperature = 200 °F

rate of decrease = 8% per minute

Temperature lost = 8% of 200 = 8/100 × 200 = 0.08 × 200 = 16 °F

It therefore means that after 1 minute, the cup of coffee loses 16 °F,

∴ Temperature after 1 minute = (starting temperature) - (lost temperature)

= 200 - 16 = 184 °F

Can you help me it’s. 2 part question I can only add one picture at a time

Recall the definition of the composition between two functions:

$(f\circ g)(x)=f(g(x))$

Similarly, but not always the same:

$(g\circ f)(x)=g(f(x))$

Use the rules of correspondence of the functions f and g to find the compositions:

$\begin{gathered} f(x)=6x-10 \\ g(x)=8-4x \end{gathered}$

Then:

$\begin{gathered} (f\circ g)(x)=f(g(x)) \\ =6\cdot g(x)-10 \\ =6(8-4x)-10 \\ =6\cdot8-6\cdot4x-10 \\ =48-24x-10 \\ =-24x+38 \\ \\ \therefore(f\circ g)(x)=-24x+38 \end{gathered}$

On the other hand:

$\begin{gathered} (g\circ f)(x)=g(f(x)) \\ =8-4\cdot f(x) \\ =8-4(6x-10) \\ =8-4\cdot6x-4\cdot-10 \\ =8-24x+40 \\ =-24x+48 \\ \\ \therefore(g\circ f)(x)=-24x+48 \end{gathered}$

Therefore, the answers are:

$\begin{gathered} (f\circ g)(x)=-24x+38 \\ (g\circ f)(x)=-24x+48 \end{gathered}$
