Answer:
Length of L is 50/8
_______________
Length of n is 10
_______________
length of m is 150/8
Explanation:
put 1/3m instead of L.
as the perimeter is 65,
1/3m+ 1/3m+m-15+m=65
2/3m+2m=50
8/3m=50
m= 50*3/8=150/8
m=18.75
L=150/8* 1/3=150/24= 50/8
n= 50/8+ 150/8-15
n= 200/8-15= 80/8= 10

Step-by-step explanation:

What is the population density of 13 lillies living in an area of 6 meters (length) and 4 meters (width)?

Answers

Answer:

0.54 lillies per square meter.

Step-by-step explanation:

First we calculate the area:

Area = length * width

Area = 6 m * 4 m = 24 m²

The we divide the population of lillies (13) by the area, to calculate the population density:

13 lillies / 24 m² = 0.54 lillies/m²

So the population density is 0.54 lillies per square meter.

Can anyone solve this? If so tell me and make sure u know what ur doing please

Answers

Answer:

-2

Step-by-step explanation:

To find the slope of a line, you need to find the [tex]\frac{rise}{run}[/tex] between two points. I will be using the points (-3, 2) and (-1, -2).

[tex]\frac{rise}{run}[/tex] = [tex]\frac{-2-2}{-1-(-3)}[/tex]

= [tex]\frac{-2-2}{-1+3}[/tex]

= [tex]\frac{-4}{2}[/tex]

= -2

Find the zeros for each function

2. f(x) = x^4 + x^3 - 11x^2 - 9x + 18

Answers

Answer:

zeros are -10, and -1 (multiplicity 2)zeros are {-3, -2, 1, 3}

Step-by-step explanation:

For higher-degree polynomials I find it extremely useful to use a graphing calculator to find the zeros.

The usual approaches are ...

use the rational root theoremtry values of x=±1narrow the search using Descartes' rule of signsestimate maximum or minimum root values

1. Rational roots will be factors of 10, so ±1, ±2, ±5, or ±10. The signs are all positive, so there are no positive real roots. The sum of odd-degree coefficients is the same as the sum of even-degree coefficients, so -1 is one of the roots. Removing that using synthetic division gives you ...

f(x) = (x +1)(x^2 +11 +10)

The quadratic (more or less obviously) factors as (x+1)(x+10), so the complete factorization is ...

f(x) = (x +1)^2(x +10)

and the zeros are {-10, -1, -1}.

2. Rational roots will be factors of 18, so will be ±1, ±2, ±3, ±6, ±9, ±18. The sum of coefficients is 0, so x=1 is a root. The rule of signs tells you that there are 2 positive real roots, so there is one more positive real root. Synthetic division tells you the factoring so far is ...

f(x) = (x -1)(x^3 +2x^2 -9x -18)

We note that the first two coefficients have the same ratio as the last two, so we can factor by grouping.

x^3 +2x^2 -9x -18 = x^2(x +2) -9(x +2) = (x^2 -9)(x +2)

Factoring the difference of squares gives you the complete factorization, hence all of the roots. (The zeros are the values of x that make the factors zero.)

f(x) = (x -1)(x +2)(x -3)(x +3)

The zeros are {-3, -2, 1, 3}.
