SCORPION-xisa [38]

Answer:

Step-by-step explanation:

f(x) =x(x-9)

X(x-9)=0

X2-9x=0

X2-9x+0=0

(X2-9X)

x(x-9)=0

X-9=0

X=9

Prototyping is a tool that enables us to quickly take basic requirements and create a limited working system

<h3>What is prototyping?</h3>

Prototyping is the type of tool that is used to convert and implement the ideas of an organisation into a tangible form.

There are two major types of prototyping which includes Evolutionary and throwaway prototyping.

Therefore, Prototyping is a tool that enables us to quickly take basic requirements and create a limited working system.

The explicit rule for a sequence is given. an=3(1/6)^n−1 Enter the recursive rule for the geometric sequence. a1= ; an=

LenaWriter [7]

Answer:

The recursive rule is a1 = 3 , an = (1/6) a(n-1)

Step-by-step explanation:

* Lets revise the recursive formula for a geometric sequence:

1. Determine if the sequence is geometric (Do you multiply, or divide,

the same amount from one term to the next?)

2. Find the common ratio. (The number you multiply or divide.)

3. Create a recursive formula by stating the first term, and then

stating the formula to be the common ratio times the

previous term.

# a1 = first term;

# an= r • a(n-1)

- Where:

- a1 = the first term in the sequence

- an = the nth term in the sequence

- an-1 = the term before the nth term

- n = the term number

- r = the common ratio

* Lets solve the problem

∵ an = 3(1/6)^(n-1) ⇒ geometric sequence

∵ The explicit rule is an = a1(r)^n-1

∴ a1 = 3 and r = 1/6

- Lets write the recursive rule

∵ a1 = first term;

∵ an= r • a(n-1)

∴ a1 = 3

∴ an = (1/6) a(n-1)

* The recursive rule is a1 = 3 , an = (1/6) a(n-1)

At a summer camp there is one counselor for every 6 campers. Write a direct variation equation for the number of campers, y, tha

e-lub [12.9K]

Answer:

The direct variation equation can be given as:

$y=6x$

Step-by-step explanation:

Given:

At a summer camp there are 6 campers under one counselor.

To find the direct variation equation for the number of campers in terms of number of counselor.

Solution:

$y\rightarrow$ Number of campers

$x\rightarrow$ Number of counselors

We have $y$ ∝ $x$

The direct variation equation can be written as:

$y=kx$

where $k$ is the direct variation constant.

There are 6 campers under one counselor. Using this statement we can find value of $k$

Given: when $x=1$ then $y=6$

We have,

$6=k(1)$

∴ $k=6$

Thus, the direct variation equation can be given as:

$y=6x$

We can find the points using the equation to plot.

$x$ $y=6x$

Find the length of side a.<br> Can you help me please?

german

Answer:

Step-by-step explanation:

Use Pythagorean theorem:

a²+b²=c²

8²+a²=10²

64+a²=100

subtract 64 from 100

a²=36

√a=√36

a= 6
