<span>28/40
An easy way to do this is to divide both the numerator and the denominator by 2 or by their greatest common factor. And since their greatest common factor is 4, divide the numerator and the denominator by 4.
Final Answer: 7/10</span>

Answer:

−224

Step-by-step explanation:

−7(7+9)−7(7+9)

=(−7)(16)−7(7+9)

=−112−7(7+9)

=−112−(7)(16)

=−112−112

Among all right circular cones with a slant height of 24, what are the dimensions (radius and height) that maximize the volum

aleksklad [387]

Answer:

5571.99

Step-by-step explanation:

We need to use the Pythagorean theorem to solve the problem.

The theorem indicates that,

$r^2+h^2=24^2 \\r^2+h^2=576\\r^2=576-h^2$

Once this is defined, we proceed to define the volume of a cone,

$v=\frac{1}{3}\pi r^2 h$

Substituting,

$v=\frac{1}{3} \pi (576-h^2)h\\v=\frac{1}{3} \pi (576h-h^3)$

We need to find the maximum height, so we proceed to calculate h, by means of its derivative and equalizing 0,

$\frac{dv}{dh} = \frac{1}{3} \pi (576-3h^2)$

$\frac{dv}{dh} = 0$ then $\rightarrow \frac{1}{3}\pi(576-3h^2)=0$

$h_1=-8\sqrt{3}\\h_2=8\sqrt{3}$

<em>We select the positiv value.</em>

We have then,

$r^2 = 576-(8\sqrt3)^2 = 384\\r=\sqrt{384}$

We can now calculate the maximum volume,

$V_{max}= \frac{1}{3}\pi r^2 h = \frac{1}{3}\pi (\sqrt{384})^2 (8\sqrt{3}) = 5571.99$

Complete the function f(x)=2x-5

Grace [21]

Replace X in the equation with the values in the table and calculate:

2X-5:

2(-4) -5 = -8 -5 = -13

2(-2)-5 = -4-5 = -9

2(1)-5 = 2-5 = -3

2(3)-5 = 6-5 = 1

2(5)-5 = 10-5 = 5
