A boat is pulled toward a dock by means of a rope wound on a drum that is located 6 ft above the bow of the boat. If the rope is

Monica [59]

Answer:

Step-by-step explanation:

Given that:

The height of the dock (h) = 6

Let represent d to be the distance between the boat and the dock

Let the length of the rope between the boat and the drum be denoted by (l)

Then, the rate of change for the length of the rope be:

dl/dt = -5 ft/s

Using Pythagoras rule to determine the relationship between these values, we have:

$l^2 = h^2 +d^2$

$l^2 = 6^2 + d^2$

$l^2 = 36 + d^2$

We relate to: $2l * \dfrac{dl}{dt} = 2d* \dfrac{dd}{dt}$

From the question;

l = 34,

So to find $\dfrac{dd}{dt}$ , we get;

$d = \sqrt{l^2 - 36}$

$d = \sqrt{34^2 - 36}$

$d = \sqrt{1156- 36}$

$d = \sqrt{1120}$

d = 33.46

So, we have:

$\dfrac{dd}{dt}= \dfrac{l}{d} \times \dfrac{dl}{dt}$

$\dfrac{dd}{dt}= \dfrac{34}{33.46} \times - 5$

$\dfrac{dd}{dt}= 1.016 \times - 5$

$\dfrac{dd}{dt}=-5.08 \ ft/sec$

3/5 × 6/7 help please

zepelin [54]

Multiply the numerator by the numerator (top number).
Multiply the denominator by the denominator (bottom number).

So 3 x 6 = 18
And 5 x 7 = 35
= 18/35

Sandy drove 55 miles per hour to Orlando. Write a function rule that relates the number of miles traveled to the hours driven.

zloy xaker [14]

The function rule that relates the number of miles traveled to the hours driven is d = 55t

<h3>What is speed?</h3>

Speed is the ratio of distance traveled by a body to the time taken.

The formula for calculating distance is expressed as:

distance = speed * time

Speed s = d/t

Given that the speed is 55 miles per hour

55 = d/t

Cross multiply

d = 55t

Hence the function rule that relates the number of miles traveled to the hours driven is d = 55t
