Answer:

B. g(x) = (x - 2)^(1/2) + 3

Step-by-step explanation:

(x - 2) is not negative and defined when x≥0
g(x) gets minimum value of 3 at minimum value of x = 2

Calculate the circumference. round to the nearest hundredth. 16 inches

goldenfox [79]

Given the radius is, r = 16 in,

The expression for the circumference of a circle is,

$C=2\pi r$

Therefore, we have,

$C=2\times3.14\times16\text{ in = }100.48\text{ in}$

Thus, the circumference of the circle is 100.48 in.

The mean height of married American women in their early twenties is 64.5 inches and the standard deviation is 2.5 inches. The m

SSSSS [86.1K]

Answer:

The equation for regression line and predicting a husband's height for married couples in their early 20s

Equation: Y'=33.67+0.54*X'

Step-by-step explanation:

r=0.5

x'=64.5

Sx=2.5

y'=68.5

Sy=2.7

General regression line equation is:

Y'=a+b*X'

so the slope of the regression line is the linear correlation coefficient multiplied by the standard deviation for y' divided by the standard deviation for x'

$b=r*\frac{S_{y}}{S_{x}}\\b=0.5*\frac{2.7}{2.5}\\b=0.54$

The intercept with axis y is the mean of the decreased by the product of the slope and the mean of x

$a=y'-b*x'\\a=68.5-0.54*64.5\\a=33.67$

The equation regression line then is:

Y'=33.67+0.54*X'

A parabola has its vertex at (2, 1) and crosses the x-axis at (1,0) anu al l

Y_Kistochka [10]

Answer:

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

Here (h, k) = (2, 1), thus

y = a(x - 2)² + 1

To find a substitute (1, 0) into the equation

0 = a(1 - 2)² + 1

0 = a + 1 ( subtract 1 from both sides )

a = - 1

Hence

y = - (x - 2)² + 1 or

y = 1 - (x - 2)² → A
