Which is the simplified form of

Mathematics

ahrayia [7]3 years ago

For this case, we must simplify the following expression:

r ^ {- 7} + s ^ {- 12}

By definition of power properties we have to:

a ^ {- 1} = \frac {1} {a ^ 1} = \frac {1} {a}

So, rewriting the expression we have:

\frac {1} {r ^ 7} + \frac {1} {s ^ {12}}

Answer:

\frac {1} {r ^ 7} + \frac {1} {s ^ {12}}

Answer:

 1           1

------ + -------    

r^7      s^12

Step-by-step explanation:

r^(-7) + s^(-12) can be re-written as

 1           1

------ + -------    by putting to use the rule:

r^7      s^12

                1

x^(-a) = ----------

              x^a

The table shows the width and length of different pictures that Coby has enlarged for the school yearbook: Enlarged Pictures Wid
Savatey [412]

Answer:

42 inches

Step-by-step explanation:

Im guessing that the the table looks like this:

Width     Length

3           7

6           14

9           21

So we can see the numbers on the right are increasing by 3 and the numbers on the left are increasing by 7.

The width is 3 times some number, and the length is 7 times the same number.

So if the width was 18 then we know the number would be 3 because 3 * 6 = 18

If that number is 6, then the length will be 6 * 7 = 42

So the length is 42 inches

A factory makes light fixtures with right regular hexagonal prisms where the edge of a hexagonal base measures 4 cm and the leng
chubhunter [2.5K]

The maximum length of the prism is highest length of the hexagonal prism

The maximum length of each prism is 8.0 cm

<h3>How to determine the maximum length of each prism?</h3>

The surface area of the hexagonal prism is calculated using:

A = 6al + 3\sqrt3 a^2

Where:

a represents the edge length; a = 4 cm

l represents the length (or height) of the prism

The surface area costs $0.04 per square centimeter.

So, we have:

C = 0.04 * [6al + 3\sqrt3 a^2]

The maximum cost is $11.

So, the equation becomes

11 = 0.04 * [6al + 3\sqrt3 a^2]

Substitute 4 for a

11 = 0.04 * [6 * 4l + 3\sqrt3 * 4^2]

Evaluate the products and exponents

11 = 0.04 * [24l + 48\sqrt3]

Divide both sides by 0.04

275 = 24l + 48\sqrt3

Subtract 48\sqrt3 from both sides

24l = 275 - 48\sqrt3

Evaluate the difference

24l = 191.9

Divide both sides by 24

l = 8.0

Hence, the maximum length of each prism is 8.0 cm

Kim's recipe for fruit punch calls for 3 cups fruit punch syrup to 4 cups of water. Tammy's recipe for fruit punch calls for 5 c
zhannawk [14.2K]
Tammy's recipe makes a sweeter fruit punch. This is because 3/4 (Kim's recipe) equals 18/24 (Tammy's recipe) and 5/6 equals 20/24 and since 20/24 is the bigger ratio, Tammy's recipe will make a sweeter fruit punch. I hope this helps. (:
