Answer:
Option A
The volume of prism is, [tex]180^{3}[/tex]
Step-by-step explanation:
From the given figure, we have
The length of the triangular prism is 6 units.
Since in the triangular cross-section we have the base (b) equals 5 units and the height (h) equals 12 units.
Using Volume of triangular prism formula: - A triangular prism whose length is l units, and whose triangular cross-section has base b units and height h units, then,
Volume(V) of the triangular prism in the cubic unit is given by;
[tex]V=\frac{1}{2}bhl[/tex]
Putting the values of [tex]l=6[/tex] unit, b=5 unit and h = 12 unit.
⇒ V = 1/2 × 5 × 6 × 12
on solving we get;
[tex]V=180^{3}[/tex]
therefore, the volume of the prism is [tex]180^{3}[/tex].

Length=50m
Breadth=25m
Diagonal be x
It will form right angle triangle Like below[tex]\setlength{\unitlength}{1cm}\begin{picture}(6,5)\linethickness{.4mm}\put(1,1){\line(1,0){4.5}}\put(1,1){\line(0,1){3.5}}\qbezier(1,4.5)(1,4.5)(5.5,1)\put(.3,2.5){\large\bf 25m}\put(2.8,.3){\large\bf 50m}\put(1.02,1.02){\framebox(0.3,0.3)}\put(.7,4.8){\large\bf A}\put(.8,.3){\large\bf B}\put(5.8,.3){\large\bf C}\qbezier(4.5,1)(4.3,1.25)(4.6,1.7)\put(3.8,1.3){\large\bf $\Theta$}\end{picture}[/tex]
So
➝x^2=50^2+25^2
➝x=√(50)^2+(25)^2
➝x=√2500+625
➝x=√3125
➝x=55.9m
➝x=56m(approx)

To graph the function g(x) = (x - 5)² - 9, shift the graph of f(x) = x²
5 units right and 9 units down
Step-by-step explanation:
Let us revise the translation
1. If the function f(x) translated horizontally to the right by h units, then
its image is g(x) = f(x - h)
2. If the function f(x) translated horizontally to the left by h units, then
its image is g(x) = f(x + h)
3. If the function f(x) translated vertically up by k units, then its image
is g(x) = f(x) + k
4. If the function f(x) translated vertically down by k units, then its image
is g(x) = f(x) - k
∵ f(x) = x²
∵ g(x) = (x - 5)² - 9
∴ g(x) = f(x - 5)² - 9
∴ h = 5 ⇒ 5 units right
∴ k = -9 ⇒ 9 units down
∴ f(x) translated 5 units to the right
∴ f(x) translated 9 units down
To graph the function g(x) = (x - 5)² - 9, shift the graph of f(x) = x²
5 units right and 9 units down
The graph of g(x) = -1/5(x + 5)² - 2 is plotted making use of the points it passes.
What is a function?A function y = f(x) is a one to one relationship between two sets X and Y where the set X is called the domain and Y the range of function f(x) ans x ∈ X and y ∈ Y.
The given function is g(x) = -1/5(x + 5)² - 2.
In order to plot its graph, consider following values of x and y as follows,
For x = 0,
g(x) = -1/5(0 + 5)² - 2
= -7
For x = -5,
g(x) = -1/5(-5 + 5)² - 2
= -2
Now as the given function has its degree as 2, it is parabolic.
Thus, its graph can be drawn as follows,
Hence, the graph of the given function is drawn clearly.

Find the maximum value of y = -x^2 + 6x + 5
Answer:
D
Step-by-step explanation:
The maximum value is the y- coordinate of the vertex
Given a quadratic in standard form , y = ax² + bx + c ( a ≠ 0 )
Then the x- coordinate of the vertex is
x = - [tex]\frac{b}{2a}[/tex]
y = - x² + 6x + 5 ← is in standard form
with a = - 1 and b = 6 , then x- coordinate of vertex is
x = - [tex]\frac{6}{-2}[/tex] = 3
Substitute x = 3 into the function for y- coordinate of vertex
y = - 3² + 6(3) + 5 = - 9 + 18 + 5 = 14
maximum value is 14 → D

On the same day, Parker’s friend, Peggy, was charged $5 for 1 1/2 lb. of gummy candy. Explain in terms of the graph why this must be a mistake.
Answer:
After a quick online search, I've found that the complete question is:
a) Parker paid $4.50 for three pounds of gummy candy. Assuming each pound of gummy candy costs the same amount, complete the table of values representing the cost of gummy candy in pounds.
Then we want to graph the points, and then comes our question:
c) On the same day, Parker’s friend, Peggy, was charged $5 for 1 1/2 lb. of gummy candy. Explain in terms of the graph why this must be a mistake.
So first, we know that this is a proportional relationship (each pound of candy costs the same)
And 0 pounds of candy should cost $0.
Then the relation between y (price) and x (number of lb) is:
y = k*lb
where k is the cost per lb.
Knowing that Parker paid $4.50 for three pounds of gummy candy, the relation is:
$4.50 = k*3lb
($4.50/3lb) = k = $1.50/lb
Then the linear relation is:
y = ($1.50/lb)*x
Now, in this question we can see that Parker's friend was charged $5 for ( 1 and 1/2) lb of candy.
If we replace those values in the equation, we get:
$5 = ($1.50/lb)*(1 + 1/2)lb = $2.25
This equation is false, then, in terms of the graph, the point ( (1 and 1/2)lb, $5) does not belong on the graph that you found in the previous points.
