Answer:

3391.2

Step-by-step explanation:

The formula for the volume of a cylinder is

pi * r^2 * h

Plugging the values in we get

3.14 * 6^2 * 30

= 3.14 * 36 * 30

= 3391.2

4x-7+7x=3x-1 <br><br> Please help hurry for crutal test.
Serhud [2]
Hey there! :D

4x-7+7x=3x-1

Combine like terms. 

11x-7=3x-1

Add 7 to both sides. 

11x= 3x+6

Subtract 3x on both sides. 

8x=6

Divide 8 into both sides.

x=6/8 or 3/4. (.75)

I hope this helps!

Circle the rate that does not belong with the other three. Explain your reasoning.
gladu [14]
<span>500ft/1minute
</span> <span>The rate which deviates from the choices given is 500ft/1min
<span>Since, 60mi/hr and 88ft/s =1440mi/day
To illustrate this hypothesis we can solve and convert 60miles/hr
60 x 24 = 1440
hence, 60miles/hr = 1440miles/day

88ft/s
1. 88ft = 0.016667miles
2. 60 seconds = 1 minute </span></span> 3. 60 minutes = 1 hr 4. 24 hours = 1 day Hence, in conversion <span><span>
60 sec x 60 min x 24 hours = 86400s
0.016667 miles x 86400 sec  = 1440 mi/day
88ft/s = 1440miles/day</span> </span>

The explicit formula for the geometric sequence Negative one-ninth, one-third, negative 1, 3, negative 9, ellipsis is f (x) = ne
storchak [24]

Answer:

Common ratio, r=-3

Recursive Formula

f(n)=-3f(n-1),$   $n\geq 2\\f(1)=-\dfrac{1}{9},

Step-by-step explanation:

The formula for the geometric sequence: -\dfrac{1}{9} ,\dfrac{1}{3}, -1,3,-9,\cdots is given as:

f(x)=-\dfrac{1}{9}(-3)^{x-1}

<u>Common Ratio</u>

Dividing the next terms by the previous terms, we obtain:

\dfrac{1}{3} \div -\dfrac{1}{9} = \dfrac{1}{3} \times -9 =-3\\3 \div -1 =-3\\-9 \div 3 =-3

Therefore, the common ratio of the sequence, r=-3

<u>Recursive Formula</u>

We observe that the next term, f(n) is obtained by the multiplication of the previous term. f(n-1) by -3.

Therefore, a recursive formula for the sequence is:

f(n)=-3f(n-1),$   $n\geq 2\\f(1)=-\dfrac{1}{9},
