Volume of right circular cone is 388.43 in³

Step-by-step explanation:

Height of circular cone = 16.8 in

Radius of circular cone = 4.7 in

We need to find Volume of right circular cone

The formula used for calculating volume of a right circular cone is: [tex]Volume=\pi r^2\frac{h}{3}[/tex]

Putting values and finding volume

[tex]Volume=\pi r^2\frac{h}{3}\\Volume=3.14\times (4.7)^2 \times \frac{16.8}{3}\\Volume=3.14\times 22.09 \times 5.6\\Volume= 388.43 \:in^3[/tex]

So, Volume of right circular cone is 388.43 in³

This is between 2 and 3 seconds, excluding both endpoints.

========================================================

Explanation:

t = elapsed time in seconds

h(t) = height of the ball at time t

Replace h(t) with 100. Then get everything to one side.

[tex]h(t)= -16t^2+80t+4\\\\100= -16t^2+80t+4\\\\0 = -16t^2+80t+4-100\\\\0= -16t^2+80t-96\\\\-16t^2+80t-96 = 0[/tex]

Next, we'll use the quadratic formula to isolate t.

Plug in a = -16, b = 80, c = -96 which are the coefficients of the last equation mentioned above.

[tex]t = \frac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\t = \frac{-80\pm\sqrt{(80)^2-4(-16)(-96)}}{2(-16)}\\\\t = \frac{-80\pm\sqrt{256}}{-32}\\\\t = \frac{-80\pm16}{-32}\\\\t = \frac{-80+16}{-32} \ \text{ or } \ t = \frac{-80-16}{-32}\\\\t = \frac{-64}{-32} \ \text{ or } \ t = \frac{-96}{-32}\\\\t = 2 \ \text{ or } \ t = 3\\\\[/tex]

Therefore, the ball's height is greater than 100 ft in the air for the interval [tex]2 < t < 3[/tex]

This is between 2 and 3 seconds, excluding both endpoints.

------------------

Check:

Let's plug in t = 2 to find that...

[tex]h(t)= -16t^2+80t+4\\\\h(2)= -16(2)^2+80(2)+4\\\\h(2)= -16(4)+80(2)+4\\\\h(2)= -64+160+4\\\\h(2)= 100\\\\[/tex]

You should find that h(3) = 100 as well. I'll let you do those steps.

Since h(2) = 100 and h(3) = 100, this confirms the two solutions we found earlier.

The factors for 2xy - 8x + 5y -20 is ( 2x + 5 ) ( y - 4 ).

Given 2xy - 8x + 5y -20

By writing like terms on one side

2xy - 8x + 5y - 20

By taking common terms outside we get

2x ( y - 4) + 5 ( y - 4)

By taking common terms we get

( 2x + 5 ) ( y - 4 )

Therefore the factors for 2xy - 8x + 5y -20 is ( 2x + 5 ) ( y - 4 )..

The expression 3⁸ / 3² is equal to 3⁶.

When dividing two numbers with the same base, we subtract the exponents. In this case, we have:

3⁸ / 3²

To simplify, we subtract the exponent of 3² from the exponent of 3⁸:

3⁽⁸⁻²⁾

3⁶

Therefore, 3⁸ / 3² is equal to 3⁶.

Answer: 1 10/39

Step-by-step explanation:

The distance that Jermaine hiked and his elevation will be 3.85km and 1103.75 m.

From the information, Stephen has hiked 5.6 kilometers and is at an elevation of 1,920 m whole on the other hand, Jacob has hiked 9.8 kilometers and is at an elevation of 2,395 m.

Therefore, since Jermaine is 1/4 of the way between Steven and Jacob. This will be:

= 1/4(5.6 + 9.8)

= 1/4 × 15.4

= 3.85km

The elevation will be:

= 1/4(1920 + 2495)

= 1/4 × 4415

= 1103.75 m

Therefore, the distance that Jermaine hiked and his elevation will be 3.85km and 1103.75 m.

The obtained quadratic function has the same stretch factor as the given function and contains the given point is  y = 3x² + 6x - 12

A quadratic function is one of the following: f(x) = ax² + bx + c, where a, b, and c are positive integers and an is not equal to zero. A parabola is a curve that represents the graph of a quadratic function.

Because a quadratic function is indeed a parabolic curve, we use the standard parabola equation.

y = a(x - h)² + k

where a = stretch factor,

h = x-coordinate of vertex and

k = y-coordinate of vertex.

The quadratic function incorporates the point (1, -3) and has the vertex x-coordinate at x = -1. h = -1 is the answer.

It also has the stretch factor of f(x) = 3x². So, a = 3.

Thus, y = a(x - h)² + k

y = 3(x - (-1))² + k

y = 3(x + 1)² + k

Now, because the quadratic function proceeds through (1, -3), we have

y = 3(x + 1)² + k

-3 = 3(1 + 1)² + k

-3 = 3(2)² + k

-3 = 3(4) + k

-3 = 12 + k

k = -3 - 12

k = -15

Similarly, find the value for y.

y = 3(x + 1)² + k

y = 3(x + 1)² - 15

y = 3(x² + 2x + 1) - 15

y = 3x² + 6x + 3 - 15

y = 3x² + 6x - 12

Therefore, the equation of the quadratic function that contains the given point and has the same stretch factor as the given function is y = 3x² + 6x - 12.
