Hi there!

To solve this problem, let's set up a proportion: 1/30 = x/45. Now, cross-multiply to get an equation: 30x = 45. Now, divide each side by 30 to figure out how many centimeters would be used to represent 45 kilometers: x = 2/3 or 0.666 cm.

Hope this helps!! :)

Write the first five terms of the recursively defined sequence. a1 = 6, ak 1 = 1 3 ak2
vova2212 [387]

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

Answer:

d. all of the above                

Step-by-step explanation:            

A two-way ANOVA generally compares the "mean differences" between different groups that are being split into two distinct independent variables which are also referred to as factors. The main aim of a two-way ANOVA is to comprehend if there is any interaction that exists between these two "independent variables" to that of the "dependent variable".

A simple main effect test is described as a phenomenon in which the effect of one specific 'independent variable' that possess within one level related to a second or the other 'independent variable'. It utilizes the "df" and the "error term" from the 'whole design'.

The post-hoc test is described as a test that generally analyzes the results of experimental data.
