Assuming Earth's gravity, the formula for the flight of the particle is: 


s(t) = -16t^2 + vt + s = -16t^2 + 144t + 160. 


This has a maximum when t = -b/(2a) = -144/[2(-16)] = -144/(-32) = 9/2. 


Therefore, the maximum height is s(9/2) = -16(9/2)^2 + 144(9/2) + 160 = 484 feet.

The temperature at 6:00 A.M. 58 degrees Fahrenheit. The temperature increased at a constant rate of 3 degrees Fahrenheit every h
Tasya [4]

Answer: c. (t:58\leq t\leq 70)

Step-by-step explanation:

given data:

T =  58 degree Celsius.

changes in temperature = 3dregres every hour = 4.

solution:

t=58+3h\\where h = 4

substitute the value for h into the equation.

t=58+3(4)\\t=58+12\\t=70

the set with 58\leq t\leq 70  best represents the function range.

At an ocean depth of 10 meters, a buoy bobs up and then down 6 meters from the ocean's depth. Ten seconds pass from the time the
Ivanshal [37]

The sine function for the given scenario is y  = 6sin ( (π / 10) x )  -  10.

<u>Step-by-step explanation:</u>

The standard formula for sine function is Asin(Bx)+C.

A buoy bobs up and down 6 meters. That is the buoy shifts vertically and horizontally  for 6 meters which is amplitude.

∴Amplitude A= 6.

Period is the distance in the x-axis that makes one full oscillation.

We know that the time taken buoy to move from its highest point to lowest point (half oscillation) is 10 seconds.

∴The period for full oscillation is 20 seconds.

Also, Period =2π divided by B.

⇒ 20 (B) = 2π.

B=2π /20.

= π/ 10.

Since the buoy is in the depth of the ocean 10 meters C = -10.

Applying all the values in the formula,

⇒y  = 6sin ( (π/ 10) x )  -  10.

The first point is the mid line,

The first point is x=0,

⇒y=6sin(0)-10.

y= -10.

∴ The line starts at the point y = -10.

The second point is either maximum or minimum value.

That is (5,-4) and (15, -16.)
