What is the end behavior of the graph of the polynomial function f(x) = 2x3 _ 26x _ 24?

1 answer:

8 0

Polynomial end behavior determines the value of the polynomial function as the value of x variable decreases in both the positive and negative direction.

For an expression with odd degree and a positive coefficient, its behavior is the same as x^3.

Thus for 2x^3 – 26x – 24;

<span>x -> - increasing y -> - increasing</span>

<span>And as x -> + increasing y -> + increasing</span>

belka [17]

Answer: The constant of proportionality is r = 5.

Step-by-step explanation:

O, we know that x and y are proportional, this means that:

y = r*x

where r is the constant of proportionality.

we also have the table

x y

7 35

12 60

20 100

Now, we can replace those values in our equation and get, for the first pair:

35 = r*7

r = 35/7 = 5

for the second pair:

60 = r*12

60/12 = 5 = r

So we can conclude that the constant of proportionality is 5.

Q. You are working on an air conditioning system. A roll of cylindrical copper tubing has an outside diameter of 7/8 inch and an

diamong [38]

The refrigerant can hold 1.92 ft³

Step-by-step explanation:

The formula to apply is that of volume

v=π *r²*h where v is volume, r is radius of cylindrical object and h is height of tubing

Finding volume of using outside diameter

v=π*7/16*7/16*12

v=49/64 *3/1 *3.14

v=7.22 ft³

Volume using inside diameter

v=π*r²*h

v=3.14*3/8*3/8*12

v=5.30 ft³

Volume the refrigerant can hold is;

7.22-5.30 = 1.92 ft³

If n - 2y = 3y- n/m,find the value of n when y = 5 and m = -3

Gnom [1K]

Answer:

37 1/2

Step-by-step explanation:

n - 2y = 3y- n/m,

find the value of n when y = 5 and m = -3

--------

n-2*5=3*5-n/-3

n-10=15+n/3

n-n/3=15+10

2n/3=25

2n=3*25

n=75/2

n=37 1/2 or 37.5

Each beehives on Larson’s honey farm usually produces 85lbs of honey per year. About how many pounds of honey will 10,000 hives

schepotkina [342]

If one of Larson's beehives produces 85lbs of honey, you need to multiply it with the given number of hives, which is 10,000.

So: 85 * 10,000 = 850,000lbs

Correlation coefficient (r) = [nΣxy - (Σx)(Σy)] / [sqrt(nΣx^2 - (Σx)^2)sqrt(nΣy^2 - (Σy)^2)]
Σx = 21 => (Σx)^2 = 21^2 = 441
Σy = 671 => (Σy)^2 = 671^2 = 450,241
Σx^2 = 1 + 4 + 9 + 16 + 25 + 36 = 91
Σy^2 = 98^2 + 101^2 + 109^2 + 117^2 + 119^2 + 127^2 = 75,665
Σxy = 1(98) + 2(101) + 3(109) + 4(117) + 5(119) + 6(127) = 2,452
r = [6(2,452) - 21(671)] / [sqrt(6(91) - 441)sqrt(6(75,665) - 450,241)] = 621/sqrt(105)sqrt(3749) = 0.99

option b is the correct answer.
