it Question 3 Sandra draws a graph representing the relationship between time and distance on her morning run. She wants to show her coach that her rate in minutes per mile was the same for the entire run. Sandra chose two points on the line and drew vertical line segments from the points to the x-axis. How can she use these segments to prove that her speed was constant? Explain your reasoning.
Answers
Using the two points on the graph, Sandra can prove that her speed was constant using: Slope (m) = (18 - 6) / (3 - 1).
What is the Slope of a Graph?The slope of a graph is the ratio of the vertical distance along the line to the horizontal distance across the line, which is given as, m = change in y / change in x.
For a proportional graph, the slope is always constant, for whichever points we choose to use on the line.
Given two points on the line that Sandra chose, (3, 18) and (1, 6), therefore:
Slope (m) = change in y / change in x
Slope (m) = (18 - 6) / (3 - 1)
Slope (m) = 12/2
Slope (m) = 6
Therefore, to show her speed, which is the slope of the line, is constant, she can use the equation below:
Slope (m) = (18 - 6) / (3 - 1).

Given the equation F=95C+32 where C is the temperature in degrees Celsius and F is the corresponding temperature in degrees Fahrenheit, and the following ordered pairs:
(25,F1), (−30,F2)
Answers
The corresponding values of F1 and F2 in the ordered pairs are 77 degrees Fahrenheit and -22 degrees Fahrenheit
How to use the equation to convert from degrees Celsius to degrees Fahrenheit?
Given: the equation F=9/5C+32 and ordered pairs: (25, F1), (−30, F2)
In order to convert the given values to degrees Fahrenheit, substitute the given values into the equation to get F1 and F2 respectively:
For (25, F1):
F = 9/5 C+32 (put C= 25 in the equation)
F1 = 9/5(25) + 32
F1 = 45 +22
F1 = 77 degrees Fahrenheit
For (−30, F2):
F = 9/5 C+32 (put C= -30 in the equation)
F2 = 9/5(-30) + 32
F2 = -54 + 32
F2 = -22 degrees Fahrenheit
Therefore, the values of F1 and F2 are 77 degrees Fahrenheit and -22 degrees Fahrenheit respectively

Write a linear function $f$ with $f\left(0\right)=7$ and $f\left(3\right)=1$ .
Answers
A linear function will have the form f(x) = mx + b.
f(0)=7 means the point (0,7) is on this line.
f(3)=1 means the point (3,1) is on the line as well.
Using those two points, we can find the slope:
m = (1-7)/(3-0) = -6/3 = -2
Since we were given f(0)=7, we also know the y-intercept.
So our function is f(x) = -2x+7

A square with sides length x are cut out of each corner of a rectangular piece of cardboard measuring 5ft by 8ft. The resulting piece of cardboard is then folded into a box without a lid. Find the volume of the largest box that can be formed this way.
Answers
The volume of the largest box that can be made from the rectangular cardboard obtained by using the value of the derivative of the function for the volume at the extremum point is 18 cubic feet
What is an extremum point in mathematics?An extremum of a function is the point where the value of the function is a maximum or a minimum.
The side length of the cut out squares = x
The width of the rectangular cardboard = 5 feet
The length of the rectangular cardboard = 8 feet
The length of the side of the cut square = 8 - 2·x
Width of the side of the cut square = 5 - 2·x
Height of the cut square = x
Volume of the cut square, V = (8 - 2·x) × (5 - 2·x) × x = 4·x³ - 26·x² + 40·x
When the volume of the box is largest, we have;[tex]V' = \dfrac{d}{dx} \left(4\cdot x^3 - 26\cdot x^2 + 40\cdot x\right) = 12\cdot x^2 - 52\cdot x + 40=0[/tex]
12·x² - 52·x + 40 = 0
3·x² - 13·x + 10 = 0
Which gives;
(3·x - 10)·(x - 1) = 0
The dimensions of the cut square that gives the maximum volume are therefore;
x = 1 or x = 10/3
When x = 10/3, we have;
V = (8 - 2×(10/3)) × (5 - 2×(10/3)) × (10/3) ≈ -200/27 < 0
When x = 1, we have;
V = (8 - 2×1) × (5 - 2×1) × 1 = 18
The value of x that gives the maximum volume is therefore, x = 1
The dimensions of the box that give the maximum volume are therefore;
Height = x = 1
Length = 8 - 2×1 = 6
Width = 5 - 2 × 1 = 3
The dimensions of the box that gives the maximum volume are;
Height = 1 ft
Length = 6 ft
Width = 3 ft
The volume of the largest box that can be formed is 18 cubic feet

The standard form of the quadratic function y=ax² + bx + c = a (x - h)² + k
How to find the standard for of a quadratic function?By definition, quadratic function is a function in the form f(x) = ax² + bx + c, where a, b, and c are numbers with a not equal to zero.
ax² + bx + c = a (x² - 2xh + h²) + kax² + bx + c
= ax² - 2ah x + (ah² + k)
Comparing the coefficients of x on both sides,b = -2ah ⇒ h = -b/2a .............................................(i)
Comparing the constants on both sides,c = ah² + kc = a (-b/2a)² + k (From (1))
c = b²/(4a) + kk = c - (b²/4a)k = (4ac - b²) / (4a)
Therefore, we can use the formulas h = -b/2a and k = (4ac - b²) / (4a) to convert the standard form to its vertex form.

Let f(x) = 1 / 2+3x and point P = (2 , 1/8)
a.) Use the following definition of the slope of the tangent line at x = a to find the slope of the line tangent to the graph of f at P.
m = lim f(a+h) - f(a) / h
tan h --> 0
b.) Determine an equation of the tangent line at P.
Answers
The slope is -3/(2+3a)² and the equation of the line is y - 1/8 = [-3/(2+3a)²](x - 2).
What is the slope?The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).
[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]
f(x) = 1 / 2+3x and point P = (2 , 1/8)
f(x+h) = 1/(2 + 3a + 3h)
f(a) = 1/(2 + 3a)
m(tan) = [1/(2 + 3a + 3h) - 1/(2 + 3a)]/h
After simplifying:
m(tan) = -3/[(2+3a)(2+3a+3h)]
h = 0
m(tan) = -3/(2+3a)²
The equation of the line:
y - 1/8 = [-3/(2+3a)²](x - 2)
Thus, the slope is -3/(2+3a)² and the equation of the line is y - 1/8 = [-3/(2+3a)²](x - 2).

To find the local extrema of a polynomial function f(x) = anxn + an-1xn-1 + … + a2x2 + a1x + a0 (or any other function), you would apply the equation f ’(x) = 0. Consider the basic form of a quadratic equation: f(x) = ax2 + bx + c. Apply the equation above to this quadratic function and solve for x. The resulting equation should be familiar from algebra/pre-calculus. What did you call this equation and how is it related to the location of a local extrema on a quadratic function?
Answers
The resulting equation is the x-coordinate of the point of local extrema of a quadratic function.
To find the local extrema of a polynomial function f(x), we apply the equation f'(x) = 0. We are given the basic form of a quadratic equation. The equation is given below.
f(x) = ax² + bx + c
We need to find the differentiation of the above equation.
f'(x) = 2ax + b
Now, we will equate the obtained equation to zero and solve for the value of the variable "x".
f'(x) = 0
2ax + b = 0
2ax = -b
x = -b/2a
This resulting equation is familiar from algebra/pre-calculus. This is the x-coordinate of the point of local extrema of a quadratic function.

There are 9216 more white squares than black squares in the 47th term with it's an odd number of 97
How to calculate the 47th termThe terms are generated with the square of odd numbers with the black squares being the addition of the odd number and one subtracted from it.
For the 47th term:
Given that the first term is consists of 25 squares with 9 black and 16 white squares
first term has odd number 5
the square of 5; 5² = 25
black squares = 5 + (5-1) = 9
white squares = 25 - 9 = 16
Therefore, for the 47th term:
47th term has odd number 97
the square of 97; 97² = 9409
black squares = 97 + (97-1) = 193
white squares = 9409 - 193 = 9216
