The first five terms of the recursively defined sequence are 6, 12, 48, 768, 196608

For given question,

We have been given the recursive formula of a sequence.

a_{k+1}=\frac{1}{3}{a_k}^2

Also, the first term of the sequence is,

a1 = 6

Substitute k = 1 in given recursive formula.

⇒ a_{1+1}=\frac{1}{3}{a_1}^2

⇒ a2 = 1/3 (6)²

⇒ a2 = (1/3) × 36

⇒ a2 = 12

Substitute k = 2 in given recursive formula.

⇒ a_{2+1}=\frac{1}{3}{a_2}^2

⇒ a3 = (1/3) × (12)²

⇒ a3 = (1/3) × 144

⇒ a3 = 48

Substitute k = 3 in given recursive formula.

⇒ a_{3+1}=\frac{1}{3}{a_3}^2

⇒ a4 = (1/3) × (48)²

⇒ a4 = (1/3) × 2304

⇒ a4 = 768

Substitute k = 4 in given recursive formula.

⇒ a_{4+1}=\frac{1}{3}{a_4}^2

⇒ a5 = (1/3) × (768)²

⇒ a5 = (1/3) × 589824

⇒ a5 = 196608

Therefore, the first five terms of the recursively defined sequence are 6, 12, 48, 768, 196608

A water wheel has a radius of 4 feet and the bottom of the wheel is 1 foot from the ground. one plank is painted white and it st
Sliva [168]

The correct option is 9 feet.

The height from the ground the white plank after the motion is 9 feet.

<h3>What is rotational motion?</h3>

Anything that spins or moves in a circular route is said to be in rotational motion. It's also referred to as angular motion and circular motion. The motion can be uniform (— in other words, the velocity v remains constant) and non-uniform, but it must be circular.

Now, according to the question;

The wheel's radius is 4 feet.

The height of a bottom of a wheel from the ground equals 1 foot.

π/3 radians is the angle where the wheel is rolled.

The following relationship describes the height of a revolving wheel.

f(t) = A·sin(B·t + C) + D

Where,

D = Mid line =  4 + 1 = 5 feet

B·t = π/3

C = 0

amplitude; A = 4

Substituting the values in the function;

f(t) = 4×sin(π/3) + 5 = 8.464 ft

f(t) = 9 (approx)

Therefore, the plank's height after the /3π/3 rotation motion = 9 ft.

Help!!!How does the slope of g(x) compare to the slope of f(x)?
attashe74 [19]

we know that

The formula to calculate the slope m between two points is equal to

m=\frac{(y2-y1)}{(x2-x1)}

Step 1

<u>Find the slope of the function f(x)</u>

Let

A( 0,-2)\\B(1,0)

substitute the values in the formula  above

m=\frac{(0+2)}{(1-0)}

m=2

<u>the slope of the function f(x) is m=2</u>

Step 2

<u>Find the slope of the function g(x)</u>

Let

C( -4,0)\\D(0,2)

substitute the values in the formula  above

m=\frac{(2-0)}{(0+4)}

m=\frac{2}{4}

m=\frac{1}{2}

the slope of the function g(x) is m=\frac{1}{2}

therefore

slope f(x) > slope g(x)

or

slope g(x) < slope f(x)

<u>the answer is the option </u>

B.The slope of g(x) is less than the slope of f(x).

The graph of Y=|x| is transformed as shown in the graph below. Which equation represents the transformed function?
MrMuchimi

Answer:

A

Step-by-step explanation:

The first thing you need to do is find the slope. Find two perfect points.

In this case I chose (0,0) and (4,1). Slope is basically rise over run. In other words, how much you go up, and how much you go right. We rise up one and to the right 4.
