The volume V of a cone varies jointly as the area of the base B and the height

seraphim [82]

Answer:

h = 9 cm.

Step-by-step explanation:

V = kBh where k is the constant of variation.

From the given info:

32 = k*16*6 = 96k

So k = 32/96 = 1/3.

So we have the equation of variation:

V = 1/3Bh

When V = 60 B = 20, so:

60 = 1/3 20h

20h = 60 * 3 = 180

h = 180 /20 = 9.

The top of a circular table has a radius of 16 inches . What is the approximate circumference of the tabletop ? Use 3.14

Elena-2011 [213]

Answer:

A)100 in

Step-by-step explanation:

Given: Radius of circular table= 16 inches

Now, solving for circumference of the tabletop.

Remember, circumference of circle= $2\pi r$

we know pi= 3.14

∴ Circumference= $2\times 3.14\times 16$

⇒ Circumference of circular tabletop= 100.48 in ≅ $100\ in$

∴ Circumference of circular tabletop is 100 in.

In a memory experiment, Alice is able to memorize words at a rate given by m '(t)= - 0.009t^2 + 0.6t. In the same memory exper

White raven [17]

Answer:

1) Ben, 2) $\Delta = 2$ , 3) $\dot m = 2.7$ , 4) $\dot M = 2.9$

Step-by-step explanation:

1) Ben has a higher rate of memorization, since the coefficient of the second power is lesser than the one from Alice.

2) The number of words can be estimated by integrating the function:

Alice

$\Delta m = -0.003\cdot (10\,min)^{3} + 0.3\cdot (10\,min)^{2}$

$\Delta m = 27$

Ben

$\Delta M = -0.001\cdot (10\,min)^{3} + 0.3\cdot (10\,min)^{2}$

$\Delta M = 29$

$\Delta = \Delta M - \Delta m$

$\Delta = 2$

3) The average amount of words per minute is:

$\dot m = \frac{27}{10}$

$\dot m = 2.7$

4) The average amount of words per minute is:

$\dot M = \frac{29}{10}$

$\dot M = 2.9$
