the function d(x) represent the distance traveled by a train traveling 80 mph during t hours after 1:00 pm. what does d (5)-d(2)
Tema [17]
The function d(t) represents the distance traveled by the train after t hours. d(5) is the total distance traveled by the train after 5 hours, which means 6:00 pm. The d(2) is the total distance traveled by the train after two hours, 3:00 pm. The expression d(5) - d(2) represents the total distance traveled by the train from 3:00 pm to 6:00 pm or for traveling at a constant speed for 3 hours.

Show your work and hurry please
spayn [35]

Answer:

15

Step-by-step explanation:

Note: Take note , absolute value will give the magnitude of the value. (Which means ignoring the + / - signs.)

Eg. | - 19 | = 19

Therefore,

\frac{12(30 - (9 +  {4}^{2})) }{10 -  | - 6| }  \\  =  \frac{12(30 - (9 + 16))}{10 - 6}  \\  =   \frac{12(30 - 25)}{4}  \\  =  \frac{12(5)}{4}  \\  =  \frac{60}{4}  \\  = 15

The price of a pedicure decreases by 4.2% from £36 on promotion.
maria [59]

A) 95.8 % of £36 will be the new price

B) The answer to part A as a decimal is £34.488

C) The new price is £34.488

<h3><u>Solution:</u></h3>

Given that the price of a pedicure decreases by 4.2% from £36 on promotion

<em><u>A) What percentage of £36 will the new price be ?</u></em>

Given that £36 is decreased by 4.2 %

New price = 36 – 4.2% of 36

\begin{array}{l}{\text { New price }=36-\frac{4.2}{100} \times 36} \\\\ {\text { New price }=36-1.512} \\\\ {\text { New price }=34.488}\end{array}

Now we have to find what percentage of £36 will the new price be

x % of 36 = 34.488

\frac{x}{100} \times 36 = 34.488\\\\x = \frac{34.488 \times 100}{36} = 95.8 \%

<em><u>B) Write your answer to part a as a decimal.</u></em>

Now, we have to find the new price in decimal form.

\begin{array}{l}{95.8 \% \times 36 \rightarrow \frac{95.8}{100} \times 36} \\\\ {\rightarrow 0.958 \times 36=34.488}\end{array}

<em><u>C) Work out the new price.</u></em>

As we calculated, the new price is £34.488
