Gerald earns a base hourly rate of $8 per hour at his job. However, if he works more than 10 hours in a week, he earns $9 per ho

Vika [28.1K]

For 10 hours of job Gerald earns 8*10=80$

For 11 hours Gerald earns 8*10+9n. n - number of working hours over 10 hours.

if Gerald work 16 hours, then he work 6 hours after 10, so n=6

8*10+9*6=80+54=134$

Answer: Gerald earns 134$ if he works 16 hours in one week.

Sorry for my bad English pls:)

The average wind speed at a local weather station is 34.8 miles per hour. The highest speed ever recorded the stations 318.0 mil

lukranit [14]

Answer:

$Difference = 283.2\ miles/hour$

Step-by-step explanation:

Given

$Average\ Speed = 34.8\ miles/hour$

$Highest\ Speed = 318.0\ miles/hour$

Required

Determine the difference in the highest speed and the average speed

$Difference = Highest\ Speed - Average\ Speed$

$Difference = 318.0\ miles/hour - 34.8\ miles/hour$

$Difference = 283.2\ miles/hour$

<em>Hence, the highest speed is 283.2 miles/hour faster than the average speed</em>

Find dy/dx by implicit differentiation. y cos x = 5x2 + 3y2

lbvjy [14]

Step 1:
Start by putting $\frac{d}{dx}$ in front of each term

$\frac{d}{dx}[y cos x]= \frac{d}{dx}[5x^2]+ \frac{d}{dx}[ 3y^2]$
-----------------------------------------------------------------------------------------------------------------
Step 2:

Deal with the terms in 'x' and the constant terms
$\frac{d}{dx}[ycosx]= 10x+ \frac{d}{dx} [3y^2]$
----------------------------------------------------------------------------------------------------------------
Step 3:

Use the chain rule for the terms in 'y'
$\frac{d}{dx}[ycosx]=10x+6y \frac{dy}{dx}$
--------------------------------------------------------------------------------------------------------------
Step 4:

Use the product rule on the term in 'x' and 'y'
$(y) \frac{d}{dx} cos x+(cos x) \frac{d}{dx}y =10x+6y \frac{dy}{dx}
$
$y(-siny)+(cosx) \frac{dy}{dx} =10x+6y \frac{dy}{dx}$
--------------------------------------------------------------------------------------------------------------

Step 5:

Rearrange to make $\frac{dy}{dx}$ the subject
$-y sin(y)+cos(x) \frac{dy}{dx} =10x+6y \frac{dy}{dx}$
$cos(x) \frac{dy}{dx}-6y \frac{dy}{dx}=10x+y sin(y)$
$[cos(x) - 6y] \frac{dy}{dx}=10x + y sin(y)$
$\frac{dy}{dx}= \frac{10x+ysin(y)}{cos(x)-6y}$ ⇒ Final Answer
