The population of kansas city, missouri was 435,000 in 1990 and 482,300 in 2005. if the population is changing linearly, write a

Jlenok [28]

Find the slope of the line connecting (1990,435000) and (2005,482300):

482300-435000 47300
m = ----------------------- = ---------------- = 3153/yr (approx)
2005 - 1990 15 yr

Use the point-slope formula to find the equation of this str. line:

y-435000 = (3153/yr)(x-1990)

The year 2020 is 30 years after 1990. Thus, the expected pop in 2020 is

given by y-435000 = 3153(30) = 94590, so that y = 529590.

Please help me on this and show me the steps to the answer.

I guess you want to calculate the value of e. If so then:

-8.e = 4 . Divide both sides by 4:

-2.e = 1. Divide both sides by 2:
-e = 1/2. Multiply both sides with (-):

e = - 1/2

Help please!!!!!!!!!!

Answer:

H. 1/9.

Step-by-step explanation:

The area of a circle is calculated by solving for π $r^2$ .

The smallest circle has an area of π $1^2$ = π * 1 = π.

The middle ring will then have an area of π $2^2$ - π = π * 4 - π = 4π - π = 3π.

The largest ring will then have an area of π $3^{2}$ - π $2^{2}$ = 9π - 4π = 5π.

5π + 3π + π = 9π

So, the probability of hitting the innermost circle will be π / 9π = 1 / 9.

Your answer is H. 1/9.

Hope this helps!

Which of the following is the product

choli [55]

Answer:

$\text{\bf{A.}}\quad\dfrac{3x^2}{x^2-6x-7}$

Step-by-step explanation:

As with multiplying any rational expressions, the numerator of the result is the product of the numerators, and the denominator of the result is the product of the denominators.

$\dfrac{3x}{x+1}\cdot\dfrac{x}{x-7}=\dfrac{(3x)(x)}{(x+1)(x-7)}=\dfrac{3x^2}{x^2-6x-7}$

_____

The denominator product is found using the distributive property. Each of the terms of one factor is multiplied by the other factor.

$(x+1)(x-7)=x(x-7)+1(x-7)\\\\=x^2-7x+1x-7=x^2-6x-7$
