Answer: first option 0 to 30 minutes.

Jusitification:

Interpolation is the prediction of an intermediate value using a linear model.

In this case, she has the data for 0, 5, 10, 15, and 30 minutes.

So, she can interpolate between any pair of consecutive data to find an intermediate value.

For example: i) if she wants the value for 20 minutes, she can interpolate between 15 and 30 minutes, ii) if she wants the value for 7 minutes, she can interpolate between 5 and 10 minutes, iii) if she wants the value for 12 mintues, she will interpolate between 10 and 15 minutes.

Answer:

a = 2  

b = 4

The equation is ⇒ y=2(4)^{x}

Step-by-step explanation:

∵ It is an exponential Regression

∴ y = ab^{x} where a ≠ 0

∵ x = 0 ⇒ y = 2

∴ 2 = ab^{0} ⇒ 2 = a(1) (where b^0 = 1)

∴ a = 2

∵ x = 1 ⇒ y = 8

∴ 8 = 2(b)^1 ⇒ 8 = 2b ⇒ b = 8 ÷ 2 = 4

∴  b = 4

∴ The equation is ⇒ y = 2(4)^{x}

The height meters of a mass projected vertically upwards at a time seconds s=ut-0.5gt².
Sergeu [11.5K]

9514 1404 393

Answer:

  t ≈ 0.590 s (ascent); 5.532 s (descent)

Step-by-step explanation:

We are interested in the values of t when s=16.

  s = 30t -4.9t²

  4.9t^2 -30t +16 = 0 . . . . . substitute 16 for s; put in standard form

The quadratic formula can be used to find the solutions:

  t = (-(-30) ±√((-30)² -4(4.9)(16)))/(2(4.9))

  t = (30 ±√586.4)/9.8 ≈ 0.59023, 5.53221 . . . . seconds after launch

a) It will take 0.590 seconds to reach 16 m height initially.

b) It will take 5.532 seconds to return to 16 m height on descent.
