The graph of the function (E) f(x) = (x + 10)(x - 3)²(x + 1) matches the given graph.
What is a graph of a function?Defining a function's graph: The collection of all points in the plane with the form (x, f(x)) that make up a function f's graph. We could also say that the graph of f is the graph of y = f(x). As a result, the graph of an equation is a particular instance of the graph of a function. We merely select a value for x, then determine the value of y that corresponds. Equations that have been solved for y are graphed as functions! In this instance, the graph of f(x) is the graph of y = x² - 3. Making points for the graph is simple.So, the function with which the given graph matches:
The graph of the option (E) f(x) = (x + 10)(x - 3)²(x + 1) is:(Refer to the graph attached below)We can easily see that coordinates of the given graph and the graph of equation (E) match.Therefore, the graph of the function (E) f(x) = (x + 10)(x - 3)²(x + 1) matches the given graph.

What is a Rectangular Prism?A rectangular prism is a three-dimensional form with six faces, where all of the faces (top, bottom, and lateral faces) are rectangles and all pairings of opposite faces are congruent. The volume of a rectangular prism is the space that it contains. We know that the volume of any prism is calculated by multiplying its base area by its height.Given:
The volume of rectangular prism = 10368 cubic inches or 6 cubic feet
Height of rectangular prism = 24 inches
It is mentioned that the chest will be twice as long as it is wide.
Let the width of the chest be x inches, so its length is 2x inches.
The volume of the chest = length × width × height
Substituting the values,
10368 = 2x × x × 24
10368 = 2x²× 24
x² = 10368/48
x = √216
x ≅ 14.7 inches ( to the nearest tenth of an inch)
Therefore, the width of the chest is 14.7 inches.

The area when the length of a rectangle is six times its width is 216m².
How to calculate the value?Let the width = w
Let the length = 6 × w = 6w
Therefore the perimeter will be:

2(w + 6w) = 84
2 × 7w = 84
14w = 84
Divide
w = 84 / 14
w = 6
Width = 6m
Length = 6w = 6 × 6 = 36m

find the 12th term of the series; 0.008, 0.04, 0.2
Answers
Answer
12th term = 390,625
Explanation
On close observation, we can see that the given series is in geometric progression.
Geometric progression has a general formula of
aₙ = a (rⁿ⁻¹)
where
aₙ = nth term
a = First term
r = Common ratio
n = number or position of the term
For this question, we need to compute the common ratio
Common Ratio = (Next term) ÷ (Current term)
= (Second term) ÷ (First term)
= (Third term) ÷ (Second term)
For this question,
Common Ratio = 0.04 ÷ 0.008 = 5
OR
0.2 ÷ 0.04 = 5
And we can see that the first term is 0.008
So, the 12th term will have the formula
aₙ = a (rⁿ⁻¹)
a = 0.008
n = 12
r = 5
a₁₂ = 0.008 (5¹²⁻¹)
= 0.008 (5¹¹)
= 0.008 (48,828,125)
= 390,625

We need to find the explicit equation for the sequence:
[tex]\begin{gathered} t\mleft(n+1\mright)=t\mleft(n\mright)-4 \\ \\ t(2)=10 \end{gathered}[/tex]First, we can complete the given table. Notice that when we subtract 4 from the n-th term, we obtain the next term (n+1).
Then, to find a previous term, we can add 4. Thus. we obtain:
n t(n)
0 14+4 = 18
1 10+4 = 14
2 10
3 10-4 = 6
4 6-4 = 2
5 2-4 = -2
Now, observing the above relations, we need to write an expression for t(n) in terms of n:
n t(n)
0 18 = 18 - 0*4
1 14 = 18 - 1*4
2 10 = 18 - 2*4
3 6 = 18 - 3*4
4 2 = 18 - 4*4
5 -2 = 18 - 5*4
