Answer:

2.19562667 in³

Step-by-step explanation:

1 kilopound foot = 12000 lb-in

658.688 Kft = 7904256 lb - in 
1 Kip Force Per Square Inch
= 1000 Psi = 1000 lb/in²
3600 x 1000 psi = 3600000 lb/in²
Therefore,

658.688 Kft /3600 kip = 7904256  in/3600000 lb × in/ lb/in² 

= 2.19562667 in³

Hello Sir/Madam
I'm writing to you in response to the claim that cars are unsafe, stinky, dirty, and noisy. They ought to be prohibited from all town and city centres so that people can cycle and walk in peace. I want to make it clear that this isn't always the case, and I'll explain why in this letter.

First of all, there are many measures in place to make sure that cars are not "downright dangerous"; for instance, speed limits, traffic lights, and zebra crossings; these make sure that nobody is at risk of being hurt by a car; they are all very important and give you the same sense of security as being at home. Instead of outlawing vehicles, our society could band together to impose more regulation on them by increasing the number of zebra crossings and traffic lights.

Second, drivers must pass a driving test to demonstrate that they are qualified to own and operate a vehicle and that they are knowledgeable about how to prevent endangering others or behaving dangerously around them. This is done to ensure that cars are not unsafe.

Another thing I want to point out is that people who live far away and work in town or city centres need a car because it's the only way they can get to their place of employment directly. It would be too inconvenient for them to cycle or walk, and people with disabilities can't cycle or walk, so they will need to use a car as a means of transportation. According to a recent survey, 85% of individuals indicated they couldn't get to work without a car, therefore banning cars would result in people losing their employment, but also in those with disabilities becoming even more disadvantaged than they already are. 

How would you feel if you couldn't walk or ride a bike to work due to a disability and lost your job as a result?
There are cars that have been produced recently that are eco-friendly, ensuring that they are not "smelly, noisy, or dirty," as described in your remark, which is another reason why I disagree with it.
These vehicles are excellent since they make people feel more at home and don't contribute to pollution.

I appreciate you reading my letter, and I hope to hear from you soon.

my heartfelt thanks

Answer:

D. (1,5) and (5.25,3.94)

Step-by-step explanation:

Given data:

y=-x²+6x--------------------------(1)

4y=21-x

x=21-4y

substitute 'x' in eq(1)

y=(21-4y)²+6(21-4y)

we have

(a-b)²=a²+b²-2ab

(21-4y)²=21²+(4y)²-2*21*4y

             =441+16y²-168y

             =16y²-168y+441

6(21-4y)=21*6-4y*6

              =-24y+126

then

y=-(21-4y)²+6(21-4y)

0=-16y²+168y-441-24y+126-y

0=-16y²+143y-315

16y²-143y+315=0

by solving the above equation we have

y=5,3.9375

if y=5

x=21-4y

  =21-4*5

  =21-20

  =1

if y=3.9375

x=21-4*3.9375

  =21-15.75

  =5.25

Answer:

see below

Step-by-step explanation:

Given the the height of  the ballon is modeled using 

h(x)  = -0.1x^2+0.8x+2.... eq 1

a) polynomial equation

Here -0.1x^2+0.8x+2 is a polynimail, hence polynomial equation is -0.1x^2+0.8x+2 = 0

b) To hit the hill : situation is shown in the picture below: 

Answer:see belowStep-by-step explanation:Given the the height of  the ballon is modeled using&n

Here AB is the with slope AD. 

Now, on throwing the balloon. 

Here the slope =  (2-h)/x = 3/4

8 - 4h = 3x 

h = (8-3x)/4 ......eq 2  

using (1) and (2) 

-0.1x^2+0.8x+2 = (8-3x)/4

-0.4x^2 + 3.2x + 8 = 8 - 3x 

-0.4x^2 = -0.2x 

0.4x = 0.2 

x = 1/2 = 0.5 

Therefore, the balloon will hit the hill at a distance of 0.5 yard.
