Answer:
area = 1539√3 in²
Step-by-step explanation:
three hexagons and one triangle:
each of the three hexagons are composed of 6 equilateral triangles just like the center triangle.
So you have 19 equilateral triangles with each side being 18 inches long.
The height (h) of a triangle will be:
h² = 18² - 9² = 324 - 81 = 243
h = √243
h = 9√3
area of one triangle = 1/2bh = (1/2)(18)(9√3) = 81√3
81√3(19 triangles) = 1539√3 in²

If the value of y varies inversely with x , which function represents the relationship between x and y if y = 48 when x = 3?
A. Y= 144/x
B. Y= 16/x
C. Y= x/16
D. Y= x/144
Answer:
A. Y = 144/x
Step-by-step explanation:
Inversely means y = 1/x
If y = 48, when x = 3
so 144/3 = 48
Therefore the answer is A
If the value of y varies inversely with x then the function Y= 144/x represents the relationship between x and y if y = 48 when x = 3
What is a function?A relation is a function if it has only One y-value for each x-value.
If y varies inversely with x, it means that y is inversely proportional to x, or y=k/x, where k is a constant of proportionality.
To find k, we can use the given values of y and x:
y = k/x
48 = k/3
k = 144
Now that we know k, we can write the function that represents the relationship between x and y:
y = 144/x
Therefore, if the value of y varies inversely with x then the function Y= 144/x represents the relationship between x and y if y = 48 when x = 3

State whether the line through points has a slope of zero or undefined. Also state whether it is horizontal or verticalline
Missing part of question
(a) (-3, 4) and (5, 4)
(b) (4, 5) and (4, -3).
Answer:
(a) (-3, 4) and (5, 4)
Zero slope
Horizontal line
(b) (4, 5) and (4, -3).
Undefined slope
Vertical line
Step-by-step explanation:
Solving (a): (-3, 4) and (5, 4)
Slope (m) is calculated as:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
This gives
[tex]m = \frac{4-4}{5 - -3}[/tex]
[tex]m = \frac{0}{8}[/tex]
[tex]m = 0[/tex]
This line has a slope of zero.
When slope equals 0, then the line is horizontal
Solving (b): (4, 5) and (4, -3)
Slope (m) is calculated as:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
This gives
[tex]m = \frac{5--3}{4-4}[/tex]
[tex]m = \frac{8}{0}[/tex]
m = undefined
This line has an undefined slope.
When the slope of a line is undefined, then the line is vertical

Find the slope of the line that passes through the two points (7, -5) and (1, -13). (Don't forget to simplify!)
I don't want no links just the answer if u don't have the answer don't give me a link
Answer:
The slope would be 4/3 or 1 1/3.
Step-by-step explanation:
When you put the coordinates in the point-slope formula, you will get -5 - (-13) over 7 - 1. The answer becomes 8/6 but if simplified, it becomes 4/3 or 1 1/3 as a mixed fraction.
What is the end behavior of the function f(x)=2/3x^3? As x→[infinity], f(x)→−[infinity] As x→−[infinity], f(x)→−[infinity] As x→[infinity], f(x)→[infinity] As x→−[infinity], f(x)→[infinity] As x→[infinity], f(x)→[infinity] As x→−[infinity], f(x)→−[infinity] As x→[infinity], f(x)→−[infinity] As x→−[infinity], f(x)→[infinity]
Answer:
As x→[infinity], f(x)→[infinity] As x→−[infinity], f(x)→−[infinity]
Step-by-step explanation:
Since f(x) =2x³/3,
Let x → + ∞
Substituting x = + ∞ into the equation, we have
f(+∞) = 2(+∞)³/3
= + 2∞³/3
= + ∞ (since + 2∞³/3 → +∞ (a larger number))
So as x → + ∞, f(x) → + ∞
Let x → - ∞
Substituting x = - ∞ into the equation, we have
f(-∞) = 2(-∞)³/3
= - 2∞³/3
= - ∞ (since - 2∞³/3 → -∞ (a larger number))
So as x → -∞, f(x) → -∞
So, the answer is As x→[infinity], f(x)→[infinity] As x→−[infinity], f(x)→−[infinity]

please I need someone to help my assignment
Answer:
All the measurements are correct
Step-by-step explanation:
What we have here are right triangles
For right triangles, the square of the hypotenuse (the side facing the right angle) equals the sum of the squares of the two other sides
Starting from the left;
a) 13^2 = 12^2 + 5^2
169 = 144 + 25
169 = 169
This triangle is valid
b) 25^2 = 24^2 + 7^2
625 = 576 + 49
625 = 625
This triangle is valid
c) 5^2 = 3^2 + 2^2
25 = 9 + 16
25 = 25

Explain the difference in meaning between 8+6 divided by 2 and 8 divided by 6 divided by 2
Answer:
In first case it is (8+6) whole divided by 2 that is 8/2+6/2 where u will get the answer 7.
in next case it is (8/6) then divided by 2
which will be 8/6*1/2.
(while converting from division to multiplication remember to take the reciprocal of the number after division sign in this 2 will become 1/2)
so and will be 8/12. 2/3 will be the answer....

Deux pays , le Pays Chaud et le Pays Froid, mènent des enquêtes sur les dépenses de consommation. Au Pays Chaud , les consommateurs achètent 60 bouteilles d'eau, 16 kilos de pain et 8 litres d'huile d'olive par année. Au Pays Froid, les consommateurs n'achètent aucune bouteille d'eau (ils sucent des glaçons qui ne leur coûtent rien), mais ils achètent 84 litres d'huile d'olive et 29 kilos de pain par année. Les prix dans les deux pays sont les mêmes, et mesurés avec la même monnaie, le dollar. Dans l'année de base, l'eau embouteillée coûtait 0,95 $ la bouteille, le pain,4,80$ le kilo, et l'huile d'olive,10,35 $ le litre. Dans l'année courante, l'eau embouteillée coûte 1,95 $ la bouteille, le pain,6,30 $ le kilo, et l'huile d'olive, 11,20 $ le litre. Quel est l'IPC au Pays Chaud dans l'année courante?
