Answer:

1,296.2 ft^3

Step-by-step explanation:

since a hemisphere is half a sphere

V = (4π/3 x r^3) / 2

V = (4π/3 x 8.5^3) / 2

V = 1,296.2 ft^3

Write the first four terms in the following sequences. A(n+1)=12 A(n) for n≥1 and A(1)=4 .

ycow [4]

Answer:Such sequences can be expressed in terms of the nth term of the sequence. In this case, the nth term = 2n. To find the 1st term, put n = 1 into the formula, to find the 4th term, replace the n's by 4's: 4th term = 2 × 4 = 8

A carpenter needs to cut four sections, each 3–feet 8–inches long, from a piece of molding. If the board is only sold by the foo

3 feet 8 inches converted to inches is 3x12+8=44inches

44inches times 4 pieces is 176 inches.

176 inches converted back to feet and inches is 176/12=14 feet 8 inches so he would need 15 feet of board

Find the first, fourth, and tenth terms of the arithmetic sequence described by the given rule.

lubasha [3.4K]

Answer:

The answer is option C.

Step-by-step explanation:

The arithmetic sequence is given by

$A(n) = - 6 + (n - 1)( \frac{1}{5} )$

where n is the number of terms

For the first term

n = 1

So we have

$A(1) = - 6 + (1 - 1)( \frac{1}{5} )$

$= - 6 + (0)( \frac{1}{5} )$

$= - 6$

For the fourth term

n = 4

$A(4) = - 6 + (4 - 1)( \frac{1}{5} )$

$= - 6 + (3)( \frac{1}{5} )$

$= - 5 \frac{2}{5}$

For the tenth term

n = 10

$A(10) = - 6 + (10 - 1)( \frac{1}{5} )$

$= - 6 + (9)( \frac{1}{5} )$

$= - 4 \frac{1}{5}$

Hope this helps you
