G(x)=1/6(8)^x-5. x=9​

Mathematics
1 answer:
Nezavi [6.7K]3 years ago
5 0

Answer:

g(9) = \frac{2048}{3}

Step-by-step explanation:

Given

g(x) = \frac{1}{6}(8)^{x-5}

x = 9

Required

Solve

Substitute 9 for x in g(x) = \frac{1}{6}(8)^{x-5}

g(9) = \frac{1}{6}(8)^{9-5}

g(9) = \frac{1}{6}(8)^{4}

Remove bracket

g(9) = \frac{1}{6}* 8^4

g(9) = \frac{1}{6}* 4096

g(9) = \frac{1* 4096}{6}

g(9) = \frac{4096}{6}

Simplify fraction

g(9) = \frac{2048}{3}

Purchasing a TV that is 20% off will save $180.
Flauer [41]

Answer:

$900

Step-by-step explanation:

a)Off given on purchasing a TV=  20%

20% on TV = $ 180

Let the original price of TV set $ x

20% of x= $180

\frac{20}{100} ×x= $180

x = $ 180× 5

x= $ 900

Hence, Original price of TV set= $ 900

b)  By second method,

20%= $180

1%= $ 9

100% = $900

Hence, the original price $ 900

Is the following UPC code valid? 375407370090. PLEASE SHOW OR EXPLAIN!!!
MAXImum [283]

Answer:

The UPC is not valid..

Step-by-step explanation:

The Universal Price Code is represented in the form of bars which is scanned when we purchase something.

The last digit of the UPC is the check digit.

Give UPC = 375407370090

To check whether the UPC is valid or not.

Step 1:

Add the digits at odd positions.

3 + 5 + 0 +3 + 0 + 9 = 20

Step 2:

Multiply the number obtained in step 1 by 3

20*3 = 60

Step 3:

The digits at even positions have to be added. The last digit has to be ignored as it is a check digit.

7 + 4 + 7 +7 +0 = 25

Step 4:

Add the numbers obtained in Step 2 and step 3

60 + 25 = 85

Step 5:

The number obtained in step 5 is subtracted from the next multiple of 10.

In the above case,

85 will be subtracted from 90.

90 - 85 = 5

For a valid UPC, the answer to step 5 is equal to the last digit of UPC.

In the above case, the answer is 5 which is not equal to zero.

So, the UPC is not Valid.
