Assuming Earth's gravity, the formula for the flight of the particle is: 


s(t) = -16t^2 + vt + s = -16t^2 + 144t + 160. 


This has a maximum when t = -b/(2a) = -144/[2(-16)] = -144/(-32) = 9/2. 


Therefore, the maximum height is s(9/2) = -16(9/2)^2 + 144(9/2) + 160 = 484 feet.

Write 2.7 x 10^4 + 120 in scientific notation.
ryzh [129]

Hey there!

2.7 * 10^4 + 120

10^4

= 10 * 10 * 10 * 10

= 100 * 100

= 10,000

2.7 * 10,000 + 120

= 27,000 + 120

= 27,120

Therefore, your answer is. [10,000 * 2.712] because 10,000 * 2.712 is approximately 27,120

Good luck on your assignment and enjoy your day!

Which of the following is the quotient of the rational expression (x-2/x+3) divided by (2/x)
zloy xaker [14]

Answer:

(x²-2x)/(2x+6)

Step-by-step explanation:

When you are asked to divide two fractions just do keep-change-flip. Keep the first fraction, change the ÷ to x and flip the second fraction upside down. So the problem becomes ((x-2)/(x+3)) times (x/2). Then just multiply numerators and multiply denominators.

ABC is a right angled triangle right angled at B . A circle with centre O inscribed in the triangle . AB=6CM BC=8CM . Find the r
Vikki [24]

Answer:

Radius = 2 cm.

Step by step explanation:

By the Pythagoras theorem  the third side of the triangle

= sqrt (6^2 + 8^2)cm = sqrt100 = 10cm.

The formula for the radius of the circle is

r = sqrt [ (s - a)(s-b)(s-c)/ s ]  where a,b,c are side lengths and s = the semi perimeter.

Here s = ( 6+8+10) / 2 = 12

So the radius r  

= sqrt [ (12-6)(12-8)(12-10)/ 12 ]

= sqrt 4

= 2 (answer).

Match the reasons with the statement.
Firlakuza [10]
To prove that x = 2 in the equation given, first, we write the given.
               (4) Given:    (A)  12 - x = 20 - 5x
   Then, add 5x to both sides of the equation,
               (3) Addition property of equality:    (B) 12 + 4x = 20
Then, subtract 12 from both sides of the equation
              (2) Subtraction property of equality:  (C) 4x = 8
Lastly, divide both sides by 4
              (1) Division property of equality :    (D) x = 2

The area of a trapezoid is 70.55 square feet. The length of the bases are 11.4 and 5.6 feet. What is the height of the trapezoid
olasank [31]

Answer:

The height is 8.3 feet

Step-by-step explanation:

The area of a trapezoid is calculated using the formula:

Area=½(sum of bases)*height

We substitute area=70.55, and the base lengths 11.4 and 5.6 feet and solve for the height.

70.55 =  \frac{1}{2} (11.4 + 5.6)h

70.55 =  \frac{1}{2} (17)h

70 .55 = 8.5h

h =  \frac{70.55}{8.5}

h = 8.3
