Answer:

(a, b, c, d) = (-12, 2, 8, 6)

Step-by-step explanation:

Put the value where x is in the equation and do the arithmetic.

When evaluating polynomials by hand, it often works well to factor an x from the terms containing x:

... y = x(3 -x) +6

x = -3: y = (-3)(3 -(-3)) +6 = -3(6) +6 = -18 +6 = -12 (a)

x = -1: y = (-1)(3 -(-1)) +6 = -1(4) +6 = -4 +6 = 2 (b)

x = 2: y = 2(3 -2) +6 = 2+6 = 8 (c)

x = 3: y = 3(3 -3) +6 = 0 +6 = 6 (d)

Answer: Correlation

Step-by-step explanation:

The statistics that should be used to determine if scores on these two surveys are related to each other is referred to as correlation.

Correlation indicates the degree by which the variables that are given are linearly related. Correlation is used in the testing and determination of the strength of association that can be found between two variables.

In this case, since the student wants to determine if degree of introversion or extroversion s associated satisfaction with life, the correlation will be appropriate to use.

A golf ball is manufactured so that if it is dropped from A feet above the ground onto a hard surface, the maximum height of eac
Lunna [17]

Step-by-step explanation:

a.) To model this scenario

Let the height of ball = y

The height of 1st= 0.5y

2nd =0.5(0.5y)

3rd = 0.5*(0.5(0.5y))

Hence the height of nth bounce can be modeled as

Height of nth bounce =(0.5ⁿ-1)*y

The exponential equation is

hn= (0.5ⁿ-1)*y

b.) if the ball is dropped from 9ft above the ground

y= 9ft

On the 4th bounce

n=4

Substituting in the exponential equation we have

h4=(0.5^4-1)*9

h4=0.5³*9

h4= 0.125*9

h4= 1.125ft

On the 4th bounce, the ball will reach a height of 1.125ft
