Answer:

2(x+8)(x-5)

Step-by-step explanation:

2x^2 + 6x − 80

Factor out a 2

2(x^2 + 3x − 40)

What 2 numbers multiply to -40 and add to 3

8*-5 = -40

8+-5 = -3

2(x+8)(x-5)

First add them together
30 and 3/4+12 and 1/4+ 16 and 1/4=30+3/4+12+1/4+16+1/4 =30+12+16+3/4+1/4+1/4=58+1+1/4=59+1/4=59 and 1/4
subtract from 72
72-59 and 1/4=72-(59+1/4)=72-59-1/4=71+1-59-1/4= 71-59+1-1/4= 71-59+4/4-1/4=12+3/4

the legnth left is 12 and 3/4 inches

The population of a certain city is projected to grow at the rate given below.

dmitriy555 [2]

Answer:

The population would be 34007.

Step-by-step explanation:

The given equation that shows the population growth rate of a certain city,

$r(t)=1800(1+\frac{6t}{3+t^2}); 0\leq t\leq 5$

Let P represents the population,

Since, change rate in population = r(t)

$\frac{dP(t)}{dt}=r(t)$

$\frac{dP(t)}{dt}=1800(1+\frac{6t}{3+t^2})$

$dP(t)=1800(1+\frac{6t}{3+t^2})dt$

Integrating both sides,

$\int dP(t)=\int 1800(1+\frac{6t}{3+t^2})dt$

$P(t)=\int 1800 dt+\int \frac{6t}{3+t^2}dt$

$P(t)=1800t + \int \frac{6t}{3+t^2}dt$

Put $3+t^2 = u\implies 2t dt = du$

$P(t)=1800t + \int \frac{3}{u}du$

$P(t)=1800t + 3\ln u + C$

$P(t)=1800t + 3\ln (3+t^2) + C$

We have P(0) = 25000

$25000 = 1800(0) + 3\ln (3) + C$

$25000 = 3\ln (3) + C$

$\implies C = 25000 - 3\ln (3) =24996.70$

Hence, the function that shows the population after t years,

$P(t)=1800t + 3\ln (3+t^2) + 24996.70$

At t = 5,

Population after 5 years would be,

$P(5) = 1800(5) + 3\ln (3+5^2) + 24996.70 = 34006.70\approx 34007$

Olin [163]

Answer:

False

Step-by-step explanation:

Regression model is a set of statistical process which estimates the relationship between two variables. The one variable is dependent variable and the other is independent variable. The statistician should not use printout C to perform a t-test in regression model.
