Answer: $ 3045.48

Step-by-step explanation:

The exponential decay equation with rate of growth r in time period t is given by :-

y=A(1-r)^t, where A is the initial amount

Given : The rate of decay of population every year : 15% =0.15

The initial value = $9500

Then , the exponential growth equation in time period t is given by :-

y=9500(1-0.15)^t=9500(0.85)^t

After t= 7 years

The value of the sailboat will be :-

y=9500(0.85)^{7}=3045.48233867\approx3045.48

Hence, the value of the sailboat after 7 years= $3045.48.

Find the distance between the points (-2, 4) and (4, -6).<br> 0 212<br> 2/(10)<br> O2V(34)
Fittoniya [83]

Answer:

2\sqrt{34}

Step-by-step explanation:

Calculate the distance (d) using the distance formula

d = √(x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (- 2, 4) and (x₂, y₂ ) = (4, - 6)

d = \sqrt{(4+2)^2+(-6-4)^2}

  = \sqrt{6^2+(-10)^2}

  = \sqrt{36+100}

  = \sqrt{136} = \sqrt{4(34)} = \sqrt{4} × \sqrt{34} = 2\sqrt{34}

The speed limit is 25 miles per hour, but it seems that many of the cars are going faster. The city places 2 counter strips 360
klio [65]
You figure out how long it would take a car traveling at 25 mph
to cover 360 ft.  Any driver who does it in less time is speeding.

           (25 mi/hr) · (5,280 ft/mile) · (1 hr / 3,600 sec)

       =    (25 · 5280 / 3600)  ft/sec  =  (36 and 2/3) feet per second.

To cover 360 ft at 25 mph, it would take

                360 ft / (36 and 2/3 ft/sec)  =   9.82 seconds .

Anybody who covers the 360 feet in less than 9.82 seconds
is moving faster than 25 mph.
_________________________________

If you're interested, here's how to do it in the other direction:

Let's say a car covers the 360 feet in ' S ' seconds.
What's the speed of the car ?

           (360 ft / S sec) · (1 mile / 5280 feet) · (3600 sec/hour)

       =    (360 · 3600) / (S · 5280)  mile/hour

       =        245.5 / S    miles per hour .

The teacher timed one car crossing both strips in 7.0 seconds.
How fast was that car traveling ?

                   245.5 / 7.0  =  35.1 miles per hour


Another teacher timed another car that took 9.82 seconds to cross
both strips.  How fast was this car traveling ?

                        245.5 / 9.82  =  25 miles per hour
