How do you do recursive formulas

2 answers:

Naily [24]3 years ago

To write a recursive formula you need to: First, determine if the sequence is geometric(For example, If your multiply, or divide, the same amount for one term or more). Next, Find the common ratio(In other words the number that you multiply or divide). Finally, we make a recursive formula by stating the first term, and then stating the formula to be the common ratio times the previous term.

Hope This Helps!!!

Answer:

Determine if the sequence is arithmetic (Do you add, or subtract, the same amount from one term to the next?)

Find the common difference.

For this case we have to define root properties:

$\sqrt [n] {a ^ n} = a ^ {\frac {n} {n}} = a$

In addition, we know that:

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

On the other hand:

$4 ^ 2 = 16$

Thus, we can rewrite the given expression as:

$\sqrt {4 ^ 2 * a ^ 8 * \frac {1} {b ^ 2}} =\\4 ^ {\frac {2} {2}} * a ^ {\frac {8} {2}} * \frac {1} {b ^ {\frac {2} {2}}} =\\4 * a ^ 4 * \frac {1} {b}$

A pair of boots that originally sold for $75.32 are on sale for 22% off.

Vesnalui [34]

Answer:

The boots will be $58.75

Step-by-step explanation:

first you cross multiply

$\frac{x}{75.32}$ x $\frac{22}{100}$

you then get 1,657.04= 100x, so divide by 100 on both sides to get

16.5704 = X

Subtract X (the 22% discount amount) from the original price to get the new price of $58.75!

What is the value of x? Round to the nearest tenth. Please Help

Elodia [21]

Answer:

<h2>x = 6.5 cm</h2>

Step-by-step explanation:

The segment 20.2 cm is the tangent. Therefore x and 20.2cm are perpendicular.

Use the Pythagorean theorem:

$leg^2+leg^2=hypotenuse^2$

We have

$leg=x,\ leg=20.2cm,\ hypotenuse=(14.7+x)cm$

Substitute:

$x^2+20.2^2=(14.7+x)^2$ <em>use (a + b)² = a² + 2ab + b²</em>

$x^2+408.04=14.7^2+(2)(14.7)(x)+x^2$ <em>subtract x² from both sides</em>

$408.04=216.09+29.4x$ <em>subtract 216.09 from both sides</em>

$191.95=29.4x$ <em>divide both sides by 29.4</em>

$x\approx6.5\ cm$
