A town has a population of 12000 and grows at 3.5% every year. What will be the population after 7 years, to the nearest whole n

Elena L [17]

Answer:

After 7 years the population will be 15268.

Step-by-step explanation:

Given a town has a population of 12000 and grows at 3.5% every year. we have to find the population after 7 years.

As the general growth formula is

$A = P(1 + r)^t$

where A = Amount after growth

P = Original amount

r = yearly growth rate

t = no. of years

here, P=12000, r=0.035, t=7

$A=12000(1+0.035)^7$

= $12000(1.035)^7$

= $15267.35\sim15268$

Hence, after 7 years the population will be 15268.

Select all of the roots of x3 2x2 – 16x– 32. –1 –2 –4 1 4 5

Lena [83]

In order to find the roots of the cubic equations by graphing you have to follow those steps

we have

$x^3+2x^2-16x-32$

we know that

The roots of the function are the values of x when the value of the function is equal to zero

Using a graphing tool

see the attached figure

The roots are

$x=-4\ x=-2\ x=4$

therefore

the answer is

$x=-4\ x=-2\ x=4$
