When Evil Kenevil was a kid, he decided to attempt to jump a distance of 30 yards using ramps that extended 9 yards high for tak

e off and landing with his motorcycle.
As the figure below illustrates, at zero yards from the take off ramp, he was 9 yards high. At 8 yards from the ramp, he was 17 yards high, and at 18 yards from the ramp, he was 18 yards high.



Since there are no rockets or wings affecting Evil’s flight, he should closely follow a parabolic path that can be modeled by a quadratic equation:
y=ax^2+bx+c, where y is the height of Evil’s bike, and x is the horizontal distance he has traveled.





1.) Using the three data points (x, y) that we know Evil passed through and the general quadratic equation, create three corresponding equations:

Equation 1: (5 pts.)


Equation 2: (5 pts.)


Equation 3: (5 pts.)


2.) Solve your system of equations from above for a, b, and c.

a = (10 pts.)


b = (10 pts.)


c = (10 pts.)


3.) Using your values of a, b, and c, what is the quadratic equation that models Evil’s jump?

Quadratic Equation: (10 pts.)


4.) What is the maximum height for Evil during this jump? (15 pts.)





5.) What is Evil’s height when he gets to the landing ramp? Is this a successful stunt? (15 pts.)




6.) Evil was at a height of 17 yards when he was 8 yards out. Where else was he at a height of 17 yards?

The Broad Street subway line express train stops at city hall every 9 minutes. The local train stops at the station every 12 min
Dmitry_Shevchenko [17]

Both the train will meet after 36 minutes.

<h3>Concept:</h3>
  • To find when both the train will meet again at the same time, we need to find the LCM of the frequency.

<h3>How to solve the given question?</h3>
  • Frequency of express train = 9 minutes = 3 × 3
  • Frequency of local train = 12 minutes = 2 × 2 × 3
  • LCM = 2 × 2 × 3 × 3 = 36

Thus, both the train will meet after 36 minutes.

6 x 10^9 divide 3x10^4 = ____x10^?
lara [203]

Answer:

2 × 10⁵

Step-by-step explanation:

The following data were obtained from the question:

6×10⁹/ 3×10⁴ =?

The above expression can be simplified as follow:

6×10⁹/ 3×10⁴ = 6×10⁹ ÷ 3×10⁴

Recall:

Aᵐ ÷ Aⁿ = Aᵐ ¯ ⁿ

Therefore,

6×10⁹ ÷ 3×10⁴ = (6/3) × 10⁹ ¯ ⁴

6×10⁹ ÷ 3×10⁴ = 2 × 10⁵

Thus, 6×10⁹/ 3×10⁴ is equal to 2 × 10⁵
