a stone is thrown downward with an intitial velocity of 29.5 m/sec will travel a distance of a meters, where s(t) = 4.9t^2 + 29.
Alenkinab [10]

Answer:

t = 9 s

Step-by-step explanation:

A stone is thrown downward with an intitial velocity of 29.5 m/sec will travel a distance of a meters, where

s(t) = -4.9t^2 + 29.4+132.3

We need to find when the stone will hit the ground. It means when s(t) = 0. So,

-4.9t^2 + 29.4t+132.3=0\\\\t=-3\ and\ t=9

So, the stone will take 9 seconds to hit the ground. Hence, this is the required solution.

The y - intercept is y=-5/3 x-4
Dimas [21]

Answer:

<u>-4 </u>

Step-by-step explanation:

This is the slope-intercept form of a line equation.

This means that -5/3 is the slope of the line.

It also means that -4 is the y intercept.

<u>-4 is the y intercept.</u>

Work out the volume of a sphere please help i’ll give u brainlest
Doss [256]

Answer:

V = 3591.4 cm³

Step-by-step explanation:

Volume of Sphere = \frac{4}{3} \pi r^3

Where r = 9.5 cm

V = \frac{4}{3} (3.14)(9.5)^3

V = \frac{4}{3} (3.14)(857.4)

V = \frac{10774}{3}

V = 3591.4 cm³

Which of the following functions illustrates a change in amplitude?
Pachacha [2.7K]

Hey there! :)

Answer:

C.

Step-by-step explanation:

For a graph to have a change in amplitude, there must be a coefficient in front of the equation, or the 'a' value.

Recall that the transformation form of a trigonometric graph is:

y = ±a(cos(b(x-h))+k

Where 'a' is the amplitude

'b' changes the period

'h' is a horizontal shift

'k' is a vertical shift

We can look at each choice and eliminate:

A. There is only a coefficient of -1 in front of the equation, which simply results in a reflection over the x-axis. This is incorrect.

B. This equation contains a b value of 2. This changes the period of the graph, not the amplitude. This is incorrect.

C. This equation contains a coefficient, or 'a' value of -2. The amplitude is changed by a factor of 2. This is correct.

D. This graph only contains a vertical shift of 1 unit up. This is incorrect.

Therefore, C is the correct answer.
