The option A and B would be wrong since it was less than the minimum value of the function. To find the cost, you just need to replace the x variable with time after 2005.
If the time is 2025 it will be
x= 2025-2005= 20

y = 15.7x + 459
y = 15.7(20) + 459
y = 314+ 459 = <span>$773.00
</span>
If the time is 2030 it will be
x= 2030-2005= 25

<span>y = 15.7x + 459
</span><span>y = 15.7(25) + 459
</span>y = 392.5+ 459 =<span>$851.50</span><span>
</span>

Graph the function: <br> f(x)=5/2x-6
MrMuchimi
Plug in any value for x and then you will get y.  Use the coordinates to plot.
Example
x= 2
5/2(2)-6
5-6
-1
(2,-1)
Then continue to do the same.

Answer:

The ball shall keep rising tills its velocity becomes zero. Let it rise to a height h feet from point of projection.

Step-by-step explanation:

Let us take the point of projection of the ball as origin of the coordinate system, the upward direction as positive and down direction as negative.

Initial velocity u with which the ball is projected upwards = + 120 ft/s

Uniform acceleration a acting on the ball is to acceleration due to gravity = - 32 ft/s²

The ball shall keep rising tills its velocity becomes zero. Let it rise to a height h feet from point of projection.

Using the formula:

v² - u² = 2 a h,

where

u = initial velocity of the ball = +120 ft/s

v = final velocity of the ball at the highest point = 0 ft/s

a = uniform acceleration acting on the ball = -32 ft/s²

h = height attained

Substituting the values we get;

0² - 120² = 2 × (- 32) h

=> h = 120²/2 × 32 = 225 feet

The height of the ball from the ground at its highest point = 225 feet + 12 feet = 237 feet.
