Answer:

see attached

Step-by-step explanation:

The scaling shown in the attachment is about as close as I can get using an on-line graphing program. You may fare better with graph paper. The vertex and x-intercepts are shown. The values at x=-3 and x=2 are y=11.

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:

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

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

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

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

Hey there!

$\bold{Mean\rightarrow your \ average}$
$\bold{The\ word \ 'average' \ means \rightarrow}$ $\bold{is \ where \ you \ add \ up \ your \ particular \ numbers \ \& you}$ $\bold{divde \ your \ result \ by \ the \ number!}$

$\bold{22.\downarrow}$

If we're rounding the answer then: $\boxed{\bold{answer:90}}$ $\checkmark$

$\bold{23.\downarrow}$

Another name for the word is "range" so, $\boxed{\bold{answer:11}}$ $\checkmark$

Good luck on your assignment and enjoy your day!

Based on the information given, it can be noted that RUTS is a rectangle because the opposite sides are parallel and have equal lengths.

<h3>Proving the rectangles.</h3>

RU = ST, UT = RS because the opposite sides are parallel and have equal length.

STU and SRU are right angles because they've 90°. Also, URS will be equal to STU. Lastly, USR = SUT because the angles are both alternate angles.

3-4z = -5+8z Can someone help?

noname [10]

3-4z=-5+8z

Add 5 to both sides

8-4z=8z

Add 4z to both sides

8=12z

Divide both sides by 12

z=12/8

Simplify

z=3/2
