Volume of a cone = pi * r² * (h/3)

If your diameter is 2, then take half of that for the radius; your radius is 1

Now plug in your given info:

V = pi * (1)² * (7/3)
= pi * 1 * (7/3)
= 7pi / 3

V ≈ 7.3304

Your answer is option D.

If you apply the changes below to the absolute value parent function, f(x) = |Xl,

TiliK225 [7]

Answer:

• Shift 5 units to the left >>> f(x) = |x+5|

• Shift 4 units down >>> f(x) = |x| - 4

Step-by-step explanation:

If we have the parent function:

f(x) = |x|

For horizontal translations:

|x-a| means horizontally translated a units right
|x+a| means horizontally translated a units left

For Vertical translation:

|x| + b means vertically translated b units up
|x| - b means vertically translated b units down

From the translation rules, we can say:

Shift 5 units left would be:

|x+5|

and

Shift 4 units down would be:

|x| - 4

Section 208 of nassau veterans Memorial Coliseum has 17 rows. The first row has 13 seats in it. If you add two seats to the prev

STatiana [176]

Row 15 has 41 seats, and the entire section has 493 seats.

We can write the explicit formula for an arithmetic sequence to represent this, since we add 2 each time:

13+2(n-1)

Using 15 for n,
13+2(15-1) = 13+2(14) = 13+28 = 41

To find the total number of seats, we evaluate the sum
$\Sigma_{n=1}^{17} 13+2(n-1)$

Using technology to evaluate this sum, it is 493.

Assume that a spherical cell, with a diameter of 18 μm, has spherical mitochondria, each with a diameter of 0.18 μm. If mitochon

laiz [17]

Since the linear dimension of the mitochondria is 10^-2 times that of the cell, the volume as a proportion of cell volume will be (10^-2)^3 = 10^-6. In order to make up 0.134 of the cell volume, there must be

(1.34×10^-1)/(10^-6) = 1.34×10^5

mitochondria in the cell.

There are about 134,000 mitochondria.
