A rubber bouncy ball is dropped from a height of 119.00 inches onto a hard flat floor. After each bounce, the ball returns to a

height that is 18.2% less than the previous maximum height. What is the maximum height reached after the 19th bounce?
What is the rate of change, b, for this situation?

Answer:

  • See below

Step-by-step explanation:

<u>18.2% less than h is:</u>

  • h*(100 - 18.2)/100 =
  • h*0.818

<u>The following series reflects this situation:</u>

  • 119, 119*0.818, 119*0.818², ...

This is a geometric series with the first term 119 and common ratio 0.818.

<u>The maximum height after 19th bounce is:</u>

  • h = 119*0.818¹⁹ = 2.62 inches (rounded)

The rate of change is same as common ratio b = 0.818.

2x(squared) + 23x-19=0
Helen [10]
Use quadratic formula

for ax^2+bx+c=0
x=\frac{-b+/- \sqrt{b^2-4ac} }{2a}

given
2x^2+23x-19=0
a=2
b=23
c=-19

x=\frac{-23+/- \sqrt{23^2-4(2)(-19)} }{2(2)}
x=\frac{-23+/- \sqrt{529-152} }{4}
x=\frac{-23+/- \sqrt{377} }{4}

x=\frac{-23+ \sqrt{377} }{4} or \frac{-23- \sqrt{377} }{4}

If sin(x) =-1/2 and tan(x) is negative what is cos(2x)
Keith_Richards [23]

Answer:

positive

Step-by-step explanation:

Using the acronym ASTC (all students take calculus), this means that if sin and tan are negative, they must be in the fourth quadrant, which means that cos is positive.

ASTC is an acronym to help students remember which of the three basic trigonometric functions are positive in which quadrants.

A: all

S: sin

T: tan

C: cos

It starts from the first quadrant: all the sin, tan, cos are positive in the first quadrant, only sin is positive in the second quadrant, only tan is positive in the third quadrant, only cos is positive in the fourth quadrant.
