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

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}.
What is the original price of the box of cereal?
Answers
Answer:
$3.20
Step-by-step explanation:
A book publisher found that the cost to produce 1000 calculus textbooks is $26,300, while the cost to produce 2000 calculus textbooks is $52,900. Assume that the cost C(x) is a linear function of x, the number of textbooks produced. What is the marginal cost of a calculus textbook?
Answers
Answer:
$26.60
Step-by-step explanation:
Calculation for the marginal cost of a calculus textbook
Marginal cost =($52,900-$26,300)/(2,000-1,000)
Marginal cost=$26,600/1,000
Marginal cost=$26.60
Or
First step
$52,900=2,000x +c equation (1)
$26,300= 1,000x+c equations (2)
Second step is to subtract equation (1) from equation (2)
$52,900=2,000x +c equation (1)
-$26,300= 1000x+c equations (2)
$26,600=1,000x
Third step is to find the marginal cost
$26,600=1,000x
x=26,600/1,000
x=$26.60
Therefore the marginal cost of a calculus textbook will be $26.60
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.

Answer:
343π/6 cm³ ≈ 179.6 cm³
Step-by-step explanation:
The formula for the volume of a sphere is one of the volume formulas worth memorizing. It is ...
V = (4/3)πr³
For r = 3.5 cm, the volume is ...
V = (4/3)π(3.5 cm)³ = 343π/6 cm³ ≈ 179.6 cm³
The volume of air in the balloon is about 179.6 cm³.

[tex]\frac{rise}{run}[/tex] = [tex]\frac{-2-2}{-1-(-3)}[/tex]
= [tex]\frac{-2-2}{-1+3}[/tex]
= [tex]\frac{-4}{2}[/tex]
