5. The Riverside Geyser in Yellowstone National Park erupts
Anastasy [175]

Answer:

Step-by-step explanation:

<h3>A.</h3>

The equation for the model of the geyser is found by substituting the given upward velocity into the vertical motion model. The problem statement tells us v=69. We assume the height is measured from ground level, so c=0. Putting these values into the model gives ...

  h(t) = -16t² +69t

__

<h3>B.</h3>

The maximum height is at a time that is halfway between the zeros of the function.

  h(t) = -16t(t -4.3125) . . . . . has zeros at t=0 and t=4.3125

The maximum height will occur at t=4.3125/2 = 2.15625 seconds. The height at that time is ...

  h(t) = -16(2.15625)(2.15625 -4.3125) = 16(2.15625²) ≈ 74.39 . . . feet

The maximum height of the geyser is about 74.4 feet.

Cameron's uncle is 3 times old as he is. 4 years ago, he was 4 times older. How old is Cameron?
erma4kov [3.2K]

Let Cameron be x years old now.

-

<u>Now:</u>

Cameron = x

Uncle =3x

-

<u>4 years ago:</u>

Cameron = x - 4

Uncle = 3x - 4

-

<u>4 years ago, Uncle is 4 times older:</u>

3x - 4 = 4(x - 4)

-

<u>Find x:</u>

3x - 4 = 4(x - 4)

3x - 4 = 4x - 16

4x - 3x = 16 - 4

x = 12

-

<u>Find the age:</u>

Cameron = x = 12

-

Answer: Cameron is 12 years old now.

Find the volume of the cone.
Ne4ueva [31]

Answer:

3142.86 cubic cm

Step-by-step explanation:

volume of cone is given by formula

volume of cone = 1/3(area of base*height)

Given radius of base = 10cm

we know area of circle is given by \pi  r^2 where r is radius of circle

thus area of base of cone is calculated below

\pi 10^2\\=> 22/7 *100\\=> 314.2857

area of base of cone is 314.2857 square cm

height = 30 cm

Thus volume of cone  = 1/3* (area of base*height)

                                   = 1/3(314.2857*30)

                                   = 1/3 *9428.571 = 3142.857.

Thus, volume of cone is 3142.857 cubic cm.

volume of cone  to the nearest hundredth is 3142.86 cubic cm
