Answer:

<u>2,365,200,000 times</u>

Step-by-step explanation:

<u>Given</u> :

  • Average heartbeat rate = 60 times/minute
  • Avg. human lifespan = 75 years

<u>To Find</u> :

  • Number of heartbeats in lifetime of 75 years

<u>Solving</u> :

  • Let the number we require be n
  • n = average heartbeat rate x 60 x 24 x 365 x 75
  • n = 60 x 60 x 24 x 365 x 75
  • n = 3600 x 24 x 365 x 75
  • n = 86400 x 365 x 75
  • n = 31536000 x 75
  • n = <u>2,365,200,000 times</u>

The graph is falling on the left hand side and rising on the right hand side.

Since the two ends of graph are in opposite direction, the exponent of variable has to be odd. For an even exponent of leading term, the two ends are in same direction.

Since the graph is falling on left and rising on right, this indicates that the coefficient of leading term is positive.

So, the leading term must have:
1) Odd exponent
2) Positive Coefficient

Thus, option Fourth is the correct answer

Write the equation of the line perpendicular to y= 2/5x+6/6 that passes through the point (-2,6)
Oliga [24]
The line to find: y = mx + b
the line perpendicular to y= 2/5x+6/6 so it has the slope m × 2/5 = -1
thus the slope m = -5/2
the line passes through the point (-2,6) so:
6 = (-5/2)×(-2) + b so b = 1


the equation of the line is y = -5/2x +1

Simplify 38 over 49 what’s the anwswer
Katyanochek1 [597]

Answer: 38 over 49 can be written as 38/49. When divided, you will get 0.77551020408. It takes lots of regrouping, but it ends eventually.

If you are reducing it as a fraction, it is not possible because there is no other number to reduce it, so it will be in it's simplest form already.
