Answer:

Person will be 24 metres above the ground after 1.50 minutes

Step-by-step explanation:

Given:

h(t)=18.8-16.7\cos \left ( \frac{2\pi t}{5} \right )

To find:

time when the person be 24 meters above the ground

Solution:

Put h(t)=24

h(t)=18.8-16.7\cos \left ( \frac{2\pi t}{5} \right )\\24=18.8-16.7\cos \left ( \frac{2\pi t}{5} \right )\\16.7\cos \left ( \frac{2\pi t}{5} \right )=18.8-24\\16.7\cos \left ( \frac{2\pi t}{5} \right )=-5.2\\\cos \left ( \frac{2\pi t}{5} \right )=\frac{-5.2}{16.7}\\\cos \left ( \frac{2\pi t}{5} \right )=-0.3114\\\frac{2\pi t}{5}=1.887\\\frac{2}{5}\times \frac{22}{7}t=1.887\\t=1.887\times \frac{5}{2}\times \frac{7}{22}\\=1.501\\\approx 1.50 \,\,minute

So, the person will be 24 metres above the ground after 1.50 minutes

Determine the slope of a line that is perpendicular to the line whose equation is x - 2y = 6.
Degger [83]

Answer:

The answer is -1/2

Step-by-step explanation:

We first start by removing x in order isolate the y variable

2y = 6 - x

y = \frac{6-x}{2}

Further, we simplify the equation in order to get the value of m (slope)

y = 3 + \frac{-1x}{2}

Therefore, our slope is equivalent to -1/2

Answer:

  • 14 nickels
  • 6 dimes

Step-by-step explanation:

The system of equations can be written ...

  n + d = 20 . . . . . . . . coins in the jar

  5n +10d = 130 . . . . . value in cents

_____

Using the first equation, we can write an expression for n:

  n = 20 -d

We can substitute this into the second equation:

  5(20 -d) +10d = 130

  100 +5d = 130 . . . . . . simplify

  5d = 30 . . . . . . . . . . . . subtract 100

  d = 6 . . . . . . . . . . . . divide by 5

  n = 20-d = 14

The jar contains 14 nickels and 6 dimes.
