Sara has a stack of 8 plates each plate is 0.5 inches and she is trying to wrap them as a gift the largest plate has a diameter of 10 inches and each plate has a diameter of 1 inch smaller than the previous plate. She has a cylindrical box with a radius of 5 in that can hold 150 cubic inches will her plates fit in the box
Answer: No her plates will not fit in the box
Step-by-step explanation: Each plate is 0.5 inches tall; therefore, the stack of 8 plates will have a height of .
Also, the diameter of the largest plate is 10 inches or has a radius of 5 inches, which matches the radius of the cylindrical box; therefore, we know that the stack of plates can fit into the base area of the cylindrical box.
What we want to figure out now is the height of the cylindrical box to see if it is greater than or equal to 4 inches—the height of the stack of plates.
The volume of a cylinder is , and since for our cylindrical box the volume is 150 cubic inches; therefore,
putting in and solving for height we get
,
which is not greater than 4 inches, which means the plates will not fit into the box since the height of the stack is greater than the height of the box.

O
B. 3(x + 6)(x + 1)
0
C. 3(x + 3)(x + 2)
D. 3(x + 1)(x + 2)
Answer:
B
Step-by-step explanation:
Given
3x² + 21x + 18 ← factor out 3 from each term
= 3(x² + 7x + 6) ← factor the quadratic
Consider the factors of the constant term (+ 6) which sum to give the coefficient of the x- term (+ 7)
The factors are + 6 and + 1, since
6 × 1 = 6 and 6 + 1 = 7, thus
x² + 7x + 6 = (x + 6)(x + 1)
Thus
3x² + 21x + 18 = 3(x + 6)(x + 1) → B

A footbridge is in the shape of an arc of a circle. The bridge is 7 ft tall and 29 ft wide. What is the radius of the circle that contains the bridge? Round your answer to the nearest tenth.
Answer:
18.5 ft (to the nearest tenth)
Step-by-step explanation:
The diameter of the circle passes through the center of the circle and divides the width of the circle into two equal parts.
We complete the circle and apply the Law of Intersecting Chords.
In the diagram, by this law:
AB X BC =DB X BE
7*x=14.5X14.5
x=14.5X14.5÷7
x=30.04
Therefore:
Length of the Diameter= 7+30.04 ft=37.04 ft
Radius =37.04/2= 18.5 ft
The radius of the circle should be 18.5 ft (to the nearest tenth).
Calculation of the radius:
Since there is the bridge is 7 ft tall and 29 ft wide.
Also,
here we apply the Law of Intersecting Chords.
So,
[tex]AB \times BC =DB \times BE\\\\7\times x=14.5\times 14.5\\\\x=14.5\times 14.5\div 7[/tex]
x=30.04
Now
Length of the Diameter= 7+30.04 ft=37.04 ft
So, Radius = 50% of 37.04 = 18.5 ft
Hence, The radius of the circle should be 18.5 ft (to the nearest tenth).

g(x) = “8x
What is the domain of g?
Answer: -1 is not in the domain and 0 and 2 are in the domain
Step-by-step explanation:
The domain of the function g(x) = “8x” is all real numbers, as there are no restrictions on the values that x can take.
The question seeks to find the domain of a function represented as g(x) = “8x. A function's domain refers to all the possible values that can be input into the function. In the case of g(x) = “8x, this is a linear function where x can take any real number value since there are no restrictions like square roots or denominators that could potentially exclude certain x values. Therefore, the domain of g is all real numbers, often represented as (-∞, +∞) or ℝ in set notation.

2

10
None of these
Answer:
D
10
Step-by-step explanation:
The requried Rocco can wear his shirts with jeans in 10 different ways. The correct answer is 10.
To determine the number of different ways Rocco can wear his shirts with jeans, we need to multiply the number of options for shirts by the number of options for jeans. In this case, Rocco has 5 different shirts and 2 different pairs of jeans.
Since he can wear any shirt with any pair of jeans, the total number of different combinations is obtained by multiplying the number of shirts (5) by the number of jeans (2):
5 shirts * 2 pairs of jeans = 10 different ways
Therefore, Rocco can wear his shirts with jeans in 10 different ways. The correct answer is 10.

Ms. Hatcher bought the pencil decoration shown below for her bulletin board.
If a = 11 in and b = 25 in, what is the area of the pencil?
Answer:
335.5 in^2
Step-by-step explanation:
The area is a rectangle and a triangle
The area of the rectangle is
A = a*b where a is 11 and b is 25
A = 11*25 =275
The area of the triangle is
A = 1/2 b*h where b is 11 and h is 11
A = 1/2 (11) * 11
A = 60.5
The total area is 275+60.5=335.5

Write the equation of the graph obtained when the graph of y=1/x is compressed vertically by a factor of 0.25, translated 4 units right, and then translated 3 units up.
Answer: The equation is y = 0.25/(x - 4) + 3
Step-by-step explanation:
If we have a function y = f(x)
A compression means that we multiply the function by a factor smaller than 1.
Then the vertical compression by a factor of 0.25 is:
y = 0.25*f(x)
a translation by A units to the right, means that we need to valuate the function in x - A.
So now we have:
y = 0.25*f(x - 4)
A translation in the y-axis means that we need to add a constant to the equation, then if we tralate it by 3 units up, we have:
y = 0.25*f(x - A) + 3
Then, if f(x) = 1/x
Our new equation is:
y = 0.25/(x - 4) + 3
Answer:
g ( x ) = 0.25 / ( x - 4 ) + 3
Step-by-step explanation:
Solution:-
- The given function is defined as an inverse function:
f ( x ) = 1 / x
- The transformation on the function of f ( x ) are of three kinds. We will use a general form to look at the effect of each transformation.
[tex]f ( x ) --- > g ( x ) = [ \frac{a}{( x +/- b)} ] + c[/tex]
Where a,b, and c are constants for transformation.
- The effect of constant a:
a > 1 ------ > Flattens the graph
0 < a < 1 -------- > Compresses the graph vertically
- The effect of constant b:
b > 0 ------ > Horizontal shift to left
b < 0 -------- > Horizontal shift to right
- The effect of constant c:
c > 0 ------ > Vertical shift up
c < 0 -------- > Vertical shift down
- Now we will determine the result of function after each transformation.
Compressed vertically by a factor of 0.25. Hence, a = 0.25 [ 0 , 1 ]k ( x ) = 0.25 / x
Translated 4 units right. The value of b = -4 , right shift : b < 0.j ( x ) = 0.25 / ( x - 4 )
translated 3 units up. The value of c = 3, up shift. c > 0g ( x ) = 0.25 / ( x - 4 ) + 3
Hence, the resulting function of all the mentioned transformations of original function f ( x ) is given as g ( x ):
g ( x ) = 0.25 / ( x - 4 ) + 3

Define a polynomial that is a difference of squares. How do you know that it is the difference of squares? How is it factored?
Answer:
Here you go, your equation should look a lot like this:
x²-16 -----> (x+4)(x-4).
Step-by-step explanation:
It's an example of what you should be writing depending on your answer. You did not include any details about your question.
The polynomial that is a difference of squares will be x²-16. It is factored as (x+4)(x-4).
What is a polynomial?Polynomial is the combination of variables and constants systematically with "n" number of power in ascending or descending order. Polynomials are used in management, computer, and math-based occupations. Variables and constants are utilized to define numbers that are known and unknown in expressions in all professions that need proficiency with polynomials.
We have to define a polynomial that is a difference of squares we have to also do factors for that polynomial.
The polynomial that is a difference of squares is found as,
x²-16
Used the below identity in order to factorize the polynomial,
a²-b²=(a+b)(a-b)
16 in its square form is written as 4².
x²-4² = (x+4)(x-4)
Thus, the polynomial that is a difference of squares will be x²-16. It is factored as (x+4)(x-4).
