Answer:

see explanation

Step-by-step explanation:

If 2 functions are inverses then the x and y- coordinates swap, that is

(x , y ) → (y, x )

Thus

a = - 3.8 ← the x- coordinate of the inverse

b = - 2.6 ← the y- coordinate of the inverse

c = 1.7 ← the x- coordinate of the inverse

d = 4.4 ← the y- coordinate of the inverse

e = 1.0 ← the x- coordinate of the inverse

The city of Oakland is experiencing a movement of its population to the suburbs. At present 85% of the total population lives in

Oxana [17]

Answer:

A. $\left[\begin{array}{cc}0.93&0.07&\\0.01&0.99&\end{array}\right]$

B. (0.85 0.15)

C. 79.2% population in the city while 20.8% population in the suburb

Step-by-step explanation:

(a) The transition matrix for the information is

C S

$\left[\begin{array}{cc}0.93&0.07&\\0.01&0.99&\end{array}\right]$

(b) the probability vector for the information is

$(\frac{85}{100} \ \ \frac{15}{100} )$

and this gives us

(0.85 0.15)

(c) we simply multiply the above two matrices to find the percent of the population can be expected to be in each category after one year after

$\left[\begin{array}{cc}0.85&0.15\end{array}\right] \left[\begin{array}{cc}0.93&0.07&\\0.01&0.99&\end{array}\right] = \left[\begin{array}{cc}0.792&0.208&\end{array}\right]$

in the city there are 79.2% while in the suburb, there are 20.8%

What is the radius of a circle whose equation is x^2+y^2-10x+6y+18=0

hichkok12 [17]

to find the radius of x^2+y^2-10x+6y+18=0, we must complete the square:

x^2 - 10x + y^2 + 6y = -18

Then:

x^2 - 10x + 5^2 - 5^2 + y^2 + 6y + 9 - 9 = -18

Collecting all three constants on the right-hand side, r^2 = -18 + 25 + 9 = 16

Then r = +sqrt(16) = +4 (answer)

I don’t get this pls help

SashulF [63]

Answer:

4 + 9x² + 1x³ + 12x⁵

Step-by-step explanation:

3x² + 6x² = (3 + 6)x² = 9x²

4 + 3x² + 8x³ + (-7x³ + 12x⁵ +6x²) = 4 + <u>3x² + 6x² </u> + <u>8x³ - 7x³ </u> + 12x⁵

= 4 + 9x² + 1x³ + 12x⁵
