What is the recursive rule for this geometric sequence? 27, 9, 3, 1, ... Enter your answers in the boxes.

ANEK [815]

Answer:

$a_n=a_{n-1}(\frac{1}{3})\\a_1=27$

Step-by-step explanation:

A recursive formula is a formula in which each term is based on the previous term.

In a geometric sequence, each term is found by multiplying the previous term by a constant.

To get from 27 to 9, then from 9 to 3, etc., we would multiply by 1/3. This makes the common ratio 1/3.

The recursive formula for a geometric sequence is

$a_n=a_{n-1}(r)$ , where $a_n$ represents the general term, $a_{n-1}$ , represents the previous term, and r represents the common ratio.

Plugging in our values, we have

$a_n=a_{n-1}(r)$

We also have to indicate what the first term, a₁, is. In this sequence, it is 21. This gives us

$a_n=a_{n-1}(\frac{1}{3})\\a_1=27$

Your coffee bar has two kinds of drink One cup of the first one costs 9 grams of juice , 4 grams of coffee and 3 grams of sugar

VMariaS [17]

Answer:

How many drinks should be sold to get a maximal profit? 468

Sales of the first one = 345 cups

Sales of the second one = 123 cups

Step-by-step explanation:

maximize 1.2F + 0.7S

where:

F = first type of drink

S = second type of drink

constraints:

sugar ⇒ 3F + 10S ≤ 3000

juice ⇒ 9F + 4S ≤ 3600

coffee ⇒ 4F + 5S ≤ 2000

using solver the maximum profit is $500.10

and the optimal solution is 345F + 123S

This section of a concrete skateboard ramp has the shape of a triangular prism. Find the volume of the triangular prism. Find th

NISA [10]

Answer:

The volume of the triangular prism: 59.2 $ft^{3}$

The value of the concrete used is: 16*4 = $64

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one. Please have a look at the attached photo

My answer:

As we know that, the formula to find out the volume of the triangular prism is:

V = $\frac{1}{2} a*b*h$ when h is the height and a&b are the length of the two square edges. So we have:

V = $\frac{1}{2}$ *4*4*7.4 = 59.2 $ft^{3}$

To find the concrete used in the ramp if the cost of concrete is $ 4.00 per cubic foot, we need to know the area of the ramp, which is:

S = 4*4 = 16 $ft^{2}$

Hence, the value of the concrete used is: 16*4 = $64

Is 1.32 a rational number or integer

Ivahew [28]

Answer:

A rational number.

Step-by-step explanation

A rational number is a ratio of whole numbers.

1/3 is the ratio of 1:3

3:1 becomes 3/1 = 3

32:10 can be written 32/10 or 16/5 or 3.2

16/5 is a rational number 16 and 5 are integers, 5 is not equal to 0.

Therefore, 3.2 which can be expressed as 16/5 is a rational number.
