4|59.43
Answer:
it is 1.15 the dude on top is right it is 1.15 i took the test and it 1.15
Step-by-step explanation:
The output of the defined number operation indicates the operations involved in the function.
The ratio of outputs for any two inputs that are 2 apart is approximately 1.149.
Reasons:
The table is presented as follows;

The ratio of the outputs for two inputs that are 2 apart, with the larger output divided by the smaller output are;
[tex]Between \ 0 \ and \ 2; \dfrac{51.71}{45} = 1.149 \overline 1[/tex]
[tex]Between \ 1 \ and \ 3; \dfrac{55.44}{48.24} \approx1.1493[/tex]
[tex]Between \ 2 \ and \ 4; \dfrac{59.43}{51.71} \approx 1.149294140[/tex]
Therefore;
The ratio of outputs for any two inputs that are 2 apart is approximately 1.149.

The table below shows the temperature (in °F) t hours after midnight in Phoenix on March 15. The table shows values of this function recorded every two hours.
Estimate the value of T′(8). Give units in your answer.
What is the meaning of T′(8)?
t 0 2 4 6 8 10 12 14
T 73 73 70 68 73 80 86 89
We need to estimate the value of T'(8) and then we need to give the meaning of this value. Since we have a table and not an expression of a function our goal is to find the Average Rate of Change between two points.
For a nonlinear graph whose slope changes at each point, the average rate of change between any two points [tex](x_{1},f(x_{1}) \ and \ (x_{2},f(x_{2})[/tex] is the slope of the line through the two points. So:
[tex]ARC=\frac{f(x_{2})-f(x_{1})}{x_{2}-x_{1}} =\frac{Change \ in \ y}{Change \ in \ x}=m_{sec}[/tex]
1. Estimated value of T′(8).
T'(8) means the derivative of the function T(t) when t = 8 hours. So, we can estimate this value using the average rate of change:
[tex]ARC=\frac{T(8)-T(6)}{8-6} =\frac{73-68}{8-6}=\frac{5}{2} \ degrees \ per \ hours[/tex]
2. The meaning of T′(8)
This means the average temperature after midnight in Phoenix on March 15, from t = 6 to t = 8 hours, that is, for each hour the temperature rises 5/2 degrees on the Fahrenheit scale. The points have been plotted in the Figure bellow.
The rate of change of the temperature is 3 degrees Celsius per hour. This response means that temperature has an instantaneous increase rate of 3 degrees Celsius per hour at [tex]t = 8\,h[/tex].
We can estimate the rate of change of the temperature, in degrees Celsius per hour, by calculating the average of two consecutive secant lines, whose expression is presented below:
[tex]T'(t) \approx \frac{1}{2}\cdot \left[\frac{T(t+\Delta t)-T(t)}{\Delta t} + \frac{T(t)-T(t-\Delta t)}{\Delta t} \right][/tex] (1)
If we know that [tex]\Delta t = 2[/tex], [tex]T(6) = 68[/tex], [tex]T(8) = 73[/tex] and [tex]T(10) = 80[/tex], then the estimated value of the rate of change of the temperature is:
[tex]T'(8) = \frac{1}{2}\cdot \left[\frac{80-73}{2}+\frac{73-68}{2} \right][/tex]
[tex]T'(8) \approx 3\,\frac{^{\circ}C}{h}[/tex]
The rate of change of the temperature is 3 degrees Celsius per hour. This response means that temperature has an instantaneous increase rate of 3 degrees Celsius per hour at [tex]t = 8\,h[/tex].

Which polynomial expression represents the area of the outermost square tile, shown below?
A square shaped tile with length x plus three is shown
x2 + 6x + 6
x2 + 9x + 6
x2 + 6x + 9
x2 − 6x + 9
Answer:
The correct answer is C, "x2 + 6x + 9."
Step-by-step explanation:
I just got it correct on the test.
Final answer:
To find the area of a square tile with sides of length x + 3, we square the binomial, resulting in the polynomial expression x² + 6x + 9, which represents the area of the square tile.
Explanation:
The question asks which polynomial expression represents the area of a square tile with sides of length x + 3. To find the area of a square, you multiply the length of one side by itself. In this case, the length of each side of the square is (x + 3), so the area of the square is (x + 3)(x + 3), or (x + 3)².
To expand this expression, we use the formula for squaring a binomial: (a + b)² = a² + 2ab + b². Applying this formula to our expression, we get:
a = x
b = 3
(x + 3)² = x² + 2(3)x + 3²
(x + 3)² = x² + 6x + 9
Therefore, the correct polynomial expression that represents the area of the square tile is x² + 6x + 9.

Solve the equation below for y.
8x - 2y = 24
A. y= 4x - 12
B. y= 12 - 4x
C. y = 8x - 24
D.y = 4x - 8
The given equation, when solved for y gives y = 4x - 12.
Hence, option A is correct.
Given is an equation 8x - 2y = 24, we need to solve for y.
To solve the equation for y, you need to isolate y on one side of the equation.
Let's do that step by step:
Start with the original equation:
8x - 2y = 24
Get rid of the constant term on the left side by subtracting 8x from both sides:
-2y = -8x + 24
Now, we want to solve for y, so we need to get rid of the coefficient of y (-2).
To do that, divide both sides by -2:
y = (-8x + 24) / -2
Simplify the right side of the equation:
y = -8x / -2 + 24 / -2
Simplify further:
y = 4x - 12
So, the solution for y is:
A. y = 4x - 12

*the quartic term
*the constant term
*the cubic term
*the quadratic term ...?
Answer:
Option 3- the cubic term
Step-by-step explanation:
Given : Polynomial [tex]d^2+d^3-d+3[/tex]
To find : To express the polynomial in standard form, which term should be written first?
Solution :
The given polynomial [tex]d^2+d^3-d+3[/tex]
The standard form of polynomial is arranged according to the higher degree to the lowest degree.
The degree is the power, first the higher degree then the lower and last the constant term.
In our given polynomial the highest degree is 3 so it is the first term of the polynomial.
The standard form is [tex]d^3+d^2-d+3[/tex]
Therefore, The required result is the cubic term is written first.
If the principal is $350 and the interest rate is 3 percent, what is the simple interest earned in one year? simple interest = P × r × t Select one of the options below as your answer: A. $10.50 B. $30.25 C. $105
Answer:
The option A. $10.50 is correct
Step-by-step explanation:
Principal = $350
Rate = 3%
⇒ Rate = 0.03
Time = 1 year
Now, Simple Interest is given by the formula : Principal × Rate × Time
Therefore, Simple Interest = 350 × 0.03 × 1
⇒ Simple Interest = $10.50
Hence, The option A. $10.50 is correct
Determine the volume of the right circular cone generated by rotating the line y = 1/3x about the y-axis between y = 0 and y = 3.
A) V = 81pi cu.units
B) V = 84pi cu.units
C) V = 82pi cu.units
D) V = 85pi cu.units
E) V = 83pi cu.units
In this exercise we want to calculate the volume of a circular cone in this way we have that the rotation will be given by:
Letter A
First let's write the rotation in favor of the X, this will be equal to:

which is a factored form of 216p^3 + 125q^3?
The factored form of [tex]\( 216p^3 + 125q^3 \) is \( (6p + 5q)(36p^2 - 30pq + 25q^2) \).[/tex]
To find the factored form of the expression [tex]\(216p^3 + 125q^3\)[/tex], we can use the sum of cubes formula:
[tex]\[ a^3 + b^3 = (a + b)(a^2 - ab + b^2) \][/tex]
Where a = 6p and b = 5q.
Substituting these values into the formula, we get:
[tex]\[ 216p^3 + 125q^3 = (6p)^3 + (5q)^3 \][/tex]
[tex]\[ = (6p + 5q)((6p)^2 - (6p)(5q) + (5q)^2) \][/tex]
[tex]\[ = (6p + 5q)(36p^2 - 30pq + 25q^2) \][/tex]
Therefore, the factored form of [tex]\( 216p^3 + 125q^3 \) is \( (6p + 5q)(36p^2 - 30pq + 25q^2) \).[/tex]
