Answer:

Cone Volume = (PI * radius^2 * height) / 3

Cone Volume = (PI * 6^2 * 12) / 3

Cone Volume = 452.3893421169 cubic inches

Answer:

1,887,436,800

Step-by-step explanation:

f(t) = a·b^t

f (t) = number of cases at year t

a = starting value = 1800 in 1983

b = growth factor = 2

t = years since 1983 = 2003 - 1983 = 20

f(t) = 1800·(2)^20 =

Use the calculator to graph the function y = 2x2 25x + 3. What are the coordinates of the turning point of the graph to the near

olga2289 [7]

Use the calculator to graph the function y = $2x^2+ 25x + 3$

In the graph , the coordinates of the vertex is the turning point of the graph.

Given function is the quadratic function. For quadratic function the graph will be U shaped parabola.

There will be only one turning point for parabola

Turning point is the vertex

To find vertex we use formula x= $\frac{-b}{2a}$

y = $2x^2+ 25x + 3$

a=2, b= 35

$x =\frac{-25}{2*2} =\frac{-25}{4}$ = -6.25

Now plug in $\frac{-25}{4}$ in f(x)

$y= 2(\frac{-25}{4})^2+ 25(\frac{-25}{4}) + 3$

Take common denominator

$y= \frac{625}{8}+ (\frac{-625}{4}) + 3 =\frac{625-1250+24}{8} =-\frac{601}{8}$ = -75.125

So coordinates of turning point is (-6.25, -75.13)

The graph is attached below.

Answer:

16 people (1/8) attended the morning session only

Step-by-step explanation:

If everyone attended something, the 1/8 of the people who didn't attend an afternoon session must have attended only the morning session.

1/8 of the 128 people = 16 people attended only the morning session
