A scientist is studying the motion of waves by measuring the distance between the crests and troughs of waves in a particular ar

ea. He set up a
series of buoys at equal intervals, and attached a depth detector to each buoy.
After gathering data, the scientist modeled the positions of the buoys at a specific instance with the given function, where x is the horizontal
distance, in feet, from the first buoy and f(x) is the depth of the water, in feet, at that location.
F(x) = 2cos(x/8x) +13

Select the correct representation of the buoy positions modeled by function

PLease tell me how to do it that will give you brainliest
Evgen [1.6K]

Answer: Table H would be the correct answer;

The rule of a function is that for each x-value given there can't be more than 1 y-value

<u>In Table F:</u>

x = -13, then y = -2

x = -13, then y = 0

x = -13, then y = 5

x = -13, then y = 7

For the x-value -13, there are 4 different y-values, so <em>it's not a function.</em>

<u>In Table G:</u>

x = -6, then y = 3

x = -1, then y = -1

x = -1, then y = 5

x = 10, then y = -9

For the x-value -1, there are 2 different y-values, hence <em>this isn't a function.</em>

<u>In Table H:</u>

x = 1, then y = 4

x = 3, then y = 4

x = 7, then y = 4

x = 12, then y = 4

For each x-value, there is only 1 y-value, so <em>this is a function.</em>

<u>In table J:</u>

x = -9, then y = -7

x = -2, then y = -5

x = 0, then y = 0

x = 0, then y = 6

For the x-value 0, there are 2 different y-value therefore <em>this isn't a function</em>

Hope this helps!

14. It costs a pool cover manufacturer $0.15 per square foot for the material they use to make pool covers. If a certain circula
laila [671]

Answer:

$2.83

Step-by-step explanation:

Diameter of the pool = 24ft

Cost of 1 ft² = $0.15

Area of the pool=?

But the pool is a circular pool,

Area of a circle = Πr² or πd²/4

π = 3.142

Area of the pool = (π * 24) / 4

Area = (3.142 * 24) / 4

Area = 18.85ft²

If 1ft² = $0.15

18.85 = $x

x = (18.85 * 0.15) / 1

x = $2.8275 = $2.83

The cost of the pool is $2.83

The discriminant of a quadratic equation is equal to -8, which statement describes the roots?
Maslowich

Answer:

  (a)  There are two complex roots

Step-by-step explanation:

The discriminant of a quadratic function describes the nature of its roots:

  • <u>negative</u>: two complex roots
  • <u>zero</u>: one real root (multiplicity 2)
  • <u>positive</u>: two distinct real roots.

__

Your discriminant of -8 is <em>negative</em>, so it indicates ...

  There are two complex roots

_____

<em>Additional comment</em>

We generally study polynomials with <em>real coefficients</em>. These will never have an odd number of complex roots. Their complex roots always come in conjugate pairs.
