4. Fraction: Explain what 5/6 means. Write an explanation of the term fraction that should work with 5/6 and %.
vazorg [7]

Answer:

See below.

Step-by-step explanation:

5/6 is a fraction. The 5 is in the numerator, and the 6 is in the denominator.

The denominator is the number of parts the unit was divided into. In this case, the denominator is 6. That means one unit, 1, was divided into 6 equal parts. Each part is one-sixth.

The numerator is the number of those parts that you use. 5 in the numerator means to use 5 of those parts, each of which is 1/6 of 1.

In other words, 5/6 means divide 1 into 6 equal parts, and take 5 of those parts.

5/6 is the same as 5 divided by 6, so as a decimal it is 0.8333...

As a percent it is 83.333...%

<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

Find a polynomial of degree 3 with a real coefficient that satisfies the given condition. Zeros: -2, 1, 0; f(2)=32
xz_007 [3.2K]
Its factors would be
(x+2)*(x-1)*(x+0)

x^2 +x -2

x^3 + 0 + x^2 + 0 -2x +0

Equation: x^3 + x^2 -2x
f(2) = 8 + 4 -4

2x^3  + 2x^2  -4x +0
f(2) = 16 + 8 -8

3x^3  + 3x^2  -6x +0
f(2) =  24 +12 -12

4x^3  + 4x^2  -8x +0
f(2) =  32 +16 -16

So, the equation is:
4x^3  + 4x^2  -8x = 0
